[en] ANALYSIS AND PROPOSITIONS FOR THE OPERATION MODEL DESIGN OF A TRANSPLANTATION UNIT INSERTED IN THE KIDNEY TRANSPLANT NETWORK OF THE STATE OF RIO DE JANEIRO / [pt] ANÁLISE E PROPOSIÇÕES PARA O PROJETO DO MODELO DE OPERAÇÃO DE UMA UNIDADE TRANSPLANTADORA INSERIDA NA REDE DE TRANSPLANTE RENAL DO ESTADO DO RIO DE JANEIRO

ANA CAROLINA PEREIRA DE V SILVA 14 June 2018 (has links)
[pt] As doenças do rim e trato urinário contribuem com cerca de 850 mil mortes a cada ano, sendo a décima segunda causa de morte do mundo. No Brasil, a diálise ainda é o procedimento mais utilizado, apesar de o transplante ser a modalidade mais recomendada, por oferecer melhor qualidade de vida ao paciente, uma possível redução do risco de mortalidade e menor custo que a diálise. Uma vez na fila, o paciente ainda se depara um conjunto de ineficiências do Sistema Nacional de Transplante. A presente pesquisa identifica que uma delas é o desalinhamento entre os atores do transplante (doador, receptor e unidade transplantadora) e que há um gap no que tange às atividades do ator unidades transplantadoras. Dessa forma, o objetivo da presente pesquisa é investigar, à luz da gestão de operações, o modelo de uma unidade transplantadora de referência, inserida na rede de transplante renal do estado do Rio de Janeiro. A partir do levantamento da literatura e de campo, são realizadas modelagens do processo de transplante renal, descrição e diagnóstico do modelo de operação da unidade transplantadora e proposições acerca do projeto de operação da unidade estudada / [en] Diseases of the kidney and urinary tract contribute about 850,000 deaths each year, being the 12th leading cause of death in the world. In Brazil, dialysis is still the most used procedure, although transplantation is the most recommended modality, because it offers a better quality of life for the patient, a possible reduction of mortality risk and lower cost than dialysis. Once in the queue, the patient still faces a set of inefficiencies of the National Transplant System. The present research identifies that one of them is the misalignment between the actors of the transplant (donor, receiver and transplantation unit) and that there is a gap with respect to the activities of the transplantation unit actors. Thus, the objective of this research is to investigate, in the light of operations management, the model of a reference transplantation unit, inserted in the kidney transplant network of the state of Rio de Janeiro. From the literature and field survey, modeling of the renal transplantation process, description and diagnosis of the operation model of the transplantation unit and propositions about the operation project of the studied unit are performed.

[en] BUSINESS PROCESS MANAGEMENT: A LIFE CYCLE APPROACH / [pt] GESTÃO DE PROCESSOS DE NEGÓCIOS: UMA ABORDAGEM DE CICLO DE VIDA

THAIS CRISTINA CHAGAS S AZEVEDO 26 March 2018 (has links)
[pt] A Gestão de Processos de Negócios (em inglês, Business Process Management – BPM) tem obtido uma importância significativa tanto para os acadêmicos quanto para os participantes no mundo industrial. Contudo, um maior número de pesquisas empíricas se faz necessário para preencher uma lacuna existente na literatura acadêmica, especialmente no que diz respeito em como as organizações estão desenvolvendo as tarefas relacionadas à gestão de seus processos, como estão identificando as barreiras enfrentadas nesta gestão e os principais facilitadores usados para superar tais barreiras. Neste contexto, este estudo apresenta os achados empíricos e as lições aprendidas em uma pesquisa-ação sobre a evolução da gestão dos processos logísticos de uma multinacional do ramo de entretenimento que teve duração de aproximadamente dois anos e meio. O estudo contou com a participação de membros da academia, profissionais da organização e consultores externos. A partir da literatura em BPM, foram estudados diversos ciclos de vida da gestão de processos de negócios propostos por distintos autores e um modelo conceitual é proposto para orientar o desenvolvimento das tarefas realizadas na gestão de processos. Diferentes fatores críticos são analisados e discutidos nesta tese de Mestrado a partir da abordagem de ciclo de vida escolhida para a gestão dos processos logísticos da companhia com foco nas dimensões organizacionais, de recursos humanos e da tecnologia da informação da organização, resultando em contribuições tanto para acadêmicos quanto para os profissionais no mercado. / [en] Business process management (BPM) has obtained significant importance for both academics and practitioners. However, the academic literature needs additional empirical researches to fulfill research-practice gaps, especially on how organizations are developing BPM tasks, identifying the barriers faced and main enablers adopted. Within this context, this paper presents the empirical findings and lessons learnt from an action research on the evolution of the logistics processes management for a multinational entertainment company. Different critical factors are analyzed and discussed within the Master Thesis regarding the entire BPM development from a life cycle approach, focusing in the organizational, people and IT dimensions, resulting in contributions for both academics and practitioners.

[en] ANALYSIS AND PERSPECTIVES FROM EMPIRICAL STUDIES IN COLLABORATIVE PLANNING, FORECASTING AND REPLENISHMENT (CPFR) / [pt] ANÁLISES E PERSPECTIVAS DE ESTUDOS EMPÍRICOS EM COLLABORATIVE PLANNING, FORECASTING AND REPLENISHMENT (CPFR)

VICTOR BARROS COURI 10 November 2017 (has links)
[pt] A prática do Planejamento, Previsão e Reabastecimento Colaborativo (em inglês, Collaborative Planning, Forecasting and Replenishment – CPFR) é um tema recente de integração de cadeias de suprimento que tem sido amplamente abordado na literatura acadêmica. O CPFR é considerado, para muitos pesquisadores, uma iniciativa mais completa e avançada que outros métodos de colaboração na cadeia, sendo, em alguns casos, uma extensão ou aprimoramento dos mesmos. O amadurecimento do tema é representado pela existência de revisões sistemáticas na literatura. Contudo, por ser o CPFR ainda um tema recente com acentuado crescimento de estudos na literatura, esta dissertação tem como objetivo realizar uma atualização destas revisões sistemáticas para verificar novos avanços no assunto, se lacunas ressaltadas já foram pelo menos parcialmente endereçadas e se tendências estão se consolidando. Mais ainda, em função da dificuldade de se implementar o CPFR na prática, um enfoque maior na análise dos estudos empíricos existentes com o objetivo de ir além de resultados parciais e particulares oferecidos na literatura é contemplado nesta dissertação, expandindo assim o escopo das revisões existentes com o foco específico em estudos empíricos. A dissertação apresenta seus resultados guiados em um framework de síntese para integração de cadeias focado em CPFR, tendo como base os passos para a condução de uma pesquisa empírica em gerência de operações, os blocos conceituais do CPFR e a contribuição dos estudos empíricos. Uma agenda para pesquisas futuras finaliza a dissertação. / [en] The practice of Collaborative Planning, Forecasting and Replenishment (CPFR) is a recent topic of supply chain integration that has been extensively covered in academic literature. The CPFR is considered by several researchers a more complete and advanced initiative than other methods of collaboration in the chain, being in some cases an extension or improvement of them. The maturation of the theme is represented by the existence of systematic reviews in the literature. However, since CPFR is still a recent topic with a strong growth of studies in the literature, this dissertation aims to carry out an update of these systematic reviews in order to verify new advances in the subject, if highlighted gaps have been at least partially addressed, and also if trends have been consolidating. Moreover, due to the difficulty of implementing CPFR in practice, a greater focus on the analysis of existing empirical studies with the objective of going beyond partial and particular results offered in the literature is contemplated in this dissertation, thus expanding the scope of the existing reviews with specific focus on empirical studies. The dissertation presents its results guided by a synthesis framework for supply chain integration focused on CPFR, based on the steps for conducting an empirical research in operations management, the conceptual building blocks for CPFR and the contribution of the empirical studies. An agenda for future research concludes the dissertation.

No. of bitstreams: 1 4874.pdf: 1459522 bytes, checksum: 5169b93eb32f56a68db468735a84aebc (MD5) Previous issue date: 2012-08-29 / The purpose of this study is to analyze the process of ownership change in an appliance company, checking the impacts brought by this process in its management. For this study, it was performed a case study, during which were conducted interviews with managers from different areas of the company. It was also based on a literature in academic journals, economic analysis and sector and public agencies publications on the process of internationalization, the Brazilian economic indicators, and the appliance industry. The 1990s was a period remarkable for the internationalization of the economy, with the rise in trade, finance and information between countries. Brazil was integrated through this process by the trade liberalization for imports, which, together with the macroeconomic and political stability, have made the country more attractive for foreign investment. This context coincided with a period of an overvalued exchange rate, which, together with high domestic interest rates, led to the acquisition of national capital companies in various industries, including appliance industry. Since then, this industry has become an oligopoly, dominated by a few large multinational companies with significant consequences for the management of companies in Brazil. In the studied company, there have been significant changes in the management staff, in the organizational structure, as well as its strategic position, with implications for the operations and human resources management. / O objetivo deste estudo é analisar o processo de mudança de propriedade de uma empresa de eletrodomésticos de linha branca nacional, verificando os principais impactos trazidos por este processo em sua gestão. Para este estudo, foi realizado um estudo de caso na empresa de linha branca analisada, na qual foram realizadas entrevistas com gestores de diferentes áreas. Também foi realizado um levantamento bibliográfico em publicações acadêmicas, de análise econômica e setorial e de órgãos públicos sobre o processo de internacionalização, indicadores econômicos do Brasil e da indústria de linha branca. A década de 1990 foi um período marcante para o processo de internacionalização da economia, com o aumento do fluxo comercial, financeiro e de informações entre países. O Brasil se integrou a esse processo por meio da abertura comercial para as importações, o que, aliado à estabilização macroeconômica e política, tornaram o país mais atrativo para receber investimentos estrangeiros. Este contexto coincidiu com um período de sobrevalorização cambial, o que, juntamente com as altas taxas de juros internas, levou à aquisição de várias empresas de capital nacional em diversas indústrias, incluindo a de eletrodomésticos de linha branca. A partir de então, esta indústria tornou-se um oligopólio, dominada por poucas grandes empresas multinacionais, o que levou a mudanças significativas na gestão de empresas no Brasil. No caso da empresa estudada, verificaram-se mudanças significativas no corpo de gestores, na estrutura organizacional, bem como em seu posicionamento estratégico, com consequências para a gestão da manufatura e de recursos humanos.

Estudo comparativo entre os fornecedores de componentes automotivos de plantas convencionais e modulares. / A comparative study between the suppliers of automotive components to conventional and to modular plants.

Thaise Graziadio 16 August 2004 (has links)
O objetivo desta tese é verificar se, e como a Estratégia Modular implementada por uma montadora de automóveis influencia os fornecedores de componentes que ocupam o 2º. nível da cadeia de suprimento modular. A estratégia visa aumentar a eficiência e a rentabilidade da produção e do negócio, e integra ações para reduzir custos e aumentar a produtividade através de montagem final em módulos, e para reduzir riscos do investimento via externalização de atividades de produção e projeto para os fornecedores. O método estudo de caso foi utilizado na análise de duas cadeias produtivas (mesma montadora), uma convencional e outra modular, e que produzem carros semelhantes. Foram selecionados dois módulos de cada carro: suspensão e cockpit. Em cada cadeia, foram estudados dois níveis de fornecedores: 1º. (ou sistemistas) e 2º. (fornecedores de componentes). Comparada à convencional, a organização modular se caracteriza pelo fluxo físico consolidado (de conjuntos e módulos), pela redução de número de fornecedores diretos da montadora, e criação de um nível intermediário, o do sistemista (fornecedor de módulo), entre outros. De modo amplo, os fornecedores sistemistas assumem atividades da produção, projeto e gestão de fornecedores, antes exclusivas da montadora, além de se instalarem perto da linha final. Entretanto, a pesquisa revelou dois tipos de sistemistas: montador, que gerencia compras de peças, monta os módulos e os entrega na linha final participação (atuação em projeto muito limitada) e o integrador que participa do projeto dos componentes (desde o conceito do produto até a produção), coordena técnica e comercialmente os fornecedores para que preços, prazos de entregas e qualidade estejam em conformidade, e garante a funcionalidade do módulo. A estratégia modular da montadora afeta, embora menos, os fornecedores nível 2, sendo que as mudanças são mais fortes para os que fornecem para o sistemista integrador pois a chance de perder contato direto com a montadora é maior e, junto, se perde acesso a novos projetos, melhorias tecnológicas e oportunidades rentáveis. O maior valor agregado ao produto do sistemista e a externalização causam várias mudanças de produto, processo e relações de suprimento entre o integrador e o nível 2. Quanto ao fornecedor do sistemista montador, as mudanças se concentram basicamente em logística e gestão da qualidade. / The objective of this dissertation is to verify and to understand how does the modular strategy being implemented by the car assembler influences the suppliers in the 2nd. level of the automotive chain. Modular strategy is conceptually based on modularity (more added value to components as they become modules) and outsourcing (suppliers’ involvement in activities usually made only by the assembler). Method case was used in the analysis of two productive chains of a single assembler, one is conventional and the other is modular, producing similar subcompact cars. We studied two modules of each car: suspension and cockpit. Each chain is composed of one car assembler, some 1st. tier suppliers (also called systemists or module suppliers) and some 2nd. tier suppliers (the components producers). The modular organization characterizes for the consolidated physical flow (assemblies and modules), the reduction of direct suppliers to the assembler, and the new role of the module suppliers. We found two kinds of modular supplier: first one is the 'assembler systemist' and it basically purchases the components of the module, assembles it and deliveries it at the final assembly line. The other type is the 'integrator systemist', to whom the changes are more significant. The 'integrator systemist' assumes relative responsibilities for development and many responsibilities for production and supply management. Generally speaking, the second tier suppliers (producers of components) are not very influenced by the Modular Strategy but when we consider the differences among the module suppliers, several points are distinguished. Effects of modularization and outsourcing are more intense on the second tier suppliers that work for the 'integrator systemist', since they face changes in the components development, in commercial practices, in productive processes and also in the supply system.

Uso dos sistemas de controle gerencial, técnicas de gestão e o desempenho de empresas do setor de autopeças

Nisiyama, Edelcio Koitiro 09 February 2012 (has links)
Made available in DSpace on 2016-03-15T19:32:42Z (GMT). No. of bitstreams: 1 Edelcio Koitiro Nisiyama.pdf: 245257 bytes, checksum: 386df80663d24330f2d7669c8f077fe6 (MD5) Previous issue date: 2012-02-09 / This research studied the relationships among the Management Control System (MCS), the Operations Management techniques and the performance in the Brazilian autoparts industry. The Simons framework (Levers of Control) was used to characterize the uses of the management control system through the dimensions of the diagnostic use and interactive use. The practices of the operations management, such as the TQM (Total Quality Management) and the Continuous Improvement Programs, also aims to get the competitive advantage and performance improvement of the firms. The effects on the performance were measured through the cost reduction and introduction of new products in order to show the effects on the operational performance and on the innovation process, supported by the concepts of the Resource-Based View (RBV), by means of a survey with questionnaires which were answered by 98 firms of the autoparts industry whose data were analyzed with a multivariate analysis technique, Structural Equation Model, with the estimation model of PLS (Partial Least Square). The results indicate that the diagnostic use of MCS is positively associated to the targets of cost reduction, and the interactive use of MCS is positively associated to the objectives of introduction of new products. This result of the interactive use is in line with Henri (2006) and Oyadomari et al (2011) who showed the influence of the interactive use on the organizational capabilities which include the innovation. The results also suggest that the use of the operations management techniques influences positively the reduction of cost, however, the hypothesis of association with the targets of introduction of new products was not statistically validated. The results of this research should be analyzed having in mind the limitations of such a research that used managers perceptions in a non-probabilistic sample in a model that simplifies the reality leaving other variables out of the model that could influence the analyzed relationships. / Esta pesquisa estudou os relacionamentos entre os usos do Sistema de Controle Gerencial (SCG), técnicas de gestão das operações e o desempenho em indústrias brasileiras de autopeças. Utilizou-se o modelo de Simons (Levers of Control) para caracterizar os usos do sistema de controle gerencial através das dimensões do uso diagnóstico e uso interativo. As práticas de gestão operacional, tais como a TQM (Total Quality Management) e Programas de Melhoria Contínua, visam também conseguir a vantagem competitiva e melhoria de desempenho das empresas. Os efeitos no desempenho foram mensurados através da redução de custos e do lançamento de novos produtos de forma a mostrar os efeitos no desempenho operacional e no processo de inovação, tendo como suporte os conceitos da VBR (Visão Baseada em Recursos), por meio de um survey com questionários respondidos por 98 empresas do setor, cujos dados foram analisados com a técnica de análise multivariada Modelagem de Equações Estruturais com o método de estimação PLS (Partial Least Square). Os resultados indicam que o uso diagnóstico do SCG está associado positivamente com as metas de redução de custos, e o uso interativo do SCG está associado positivamente com os objetivos de lançamento de novos produtos. Este resultado do uso interativo está em linha com Henri (2006) e Oyadomari et al (2011) que mostraram a influência do uso interativo nas competências organizacionais entre as quais está a inovação. Os resultados sugerem também que o uso das técnicas de gestão das operações influencia positivamente a redução de custos, entretanto, a hipótese de associação com as metas de lançamento de novos produtos não foi validada estatisticamente. Os resultados desta pesquisa devem ser analisados à luz das limitações deste tipo de pesquisa que considerou percepções de gestores de uma amostra não probabilística em um modelo que simplifica a realidade deixando de fora outras variáveis que podem influenciar as relações analisadas.

Information Usage in Smart Material Flows : An Evaluation of the Prerequisites of how to Become Smart in the Material Flow from a User Perspective within Assembly at an Industrial Manufacturing Company

Eriksson, Josefin, Eldered, Anna January 2017 (has links)
IT is a well-integrated function within most companies and its importance grows bigger by the day. With new solutions and concepts being introduced continuously it is important to be aware of the ever-changing possibilities found within IT. One of these changes is the concept of Industrie 4.0 which poses as a revolutionary way to do business by connecting the real world with the virtual one to a greater extent than what is done today. Research has shown that there are many possible benefits of implementing Industrie 4.0 and also Smart Factory, such as improved inventory control and faster reaction time. Since these concepts are quite new, no real definition exists and the congruence between the academic and business world is not always at the same level, and therefore the first steps are not yet defined. Therefore, this study tried to reduce the gap between these two worlds by offering concrete recommendations of what needs to be done to be able to apply Industrie 4.0 in the real world at Scania CV AB and Scania IT. Scania CV AB posed as a case company to find out where to start on the road to become smart. Currently there are many functions using the services of Scania IT, but exactly how the systems are used is not known by Scania IT. To be able to provide the necessary services for the various functions of Scania CV AB and start the road of becoming smart, Scania IT needs to know how the systems are used and what information that is currently missing. A formulated strategy of Scania, as a whole, is to be able to collect and analyse information in order to have a more Intuitive Presence and Predictable Future, two words meaning that more proactive work can be conducted and more autonomous decisions can be made. To be able to fulfil this vision, knowledge about the needed information must be acquired by Scania IT. With focus on the information connected to the material flow before the material reaches the assembly lines found at Scania CV AB the purpose of this study was to identify and analyse information and actions needed in the material flow from a user perspective, to become Intuitive and Predictable as part of the concept Industrie 4.0. A set of research objectives were formulated as a guide for the study. By first identifying, with the help of the first research objective, the information input and output for the functions at Scania CV AB connected to the material flow, with a base in the functions planning material, it was identified that at different production sites different standards of working exist, but also differences in the IT usage and system configurations was found.  The second research objective focused on what information should be available for production and material planning according to a literature review and this was later compared with the findings at Scania, which composed the third research objective. As it turned out, Scania uses the correct set of basic information such as forecasting, production plan, and calculations of gross demand, along with information regarding costs, lead times, and inventory. However, how to use the information is not standardized and the users of the IT systems perceived the information as hard to find and difficult to interpret. The fourth research objective focused on the concept of Industrie 4.0 and Smart Factories by studying literature, an external company and the ideas that Scania CV AB have, to see what must be done before a Digital Factory can be created. The recommendations for Scania IT were based on the result on the analyses and they can be summarized by the need of further standardization of information and information usage to be able to start the road of becoming Smart and take one step closer to the concepts of Smart Factory and Industrie 4.0.

資源導向智慧家庭服務維運機制的設計與實現 / Design and implementation of a resource-oriented smart home service operation management platform

陳映如 Unknown Date (has links)
智慧家庭的概念早在半世紀前就被提出,但至今仍被認為是豪宅的配備, 到目前為止也沒有「智慧家庭產業」出現。解決智慧家庭系統的維運議題, 是智慧家庭技術普及化,進而形成產業的重要前提。Broadband Forum 所提 出的 CWMP 是目前較普及與成熟的維運技術,但 CWMP 在軟體架構與軟 體設計上仍具有改善空間,包含用企業級技術來定義嵌入裝置規範,導致 效能與擴充性不佳;領域模型設計不良,開發人員難以學習與理解,以及 Web 回呼(Callback)機制未臻完善,無法彈性應對各種裝置回呼狀況。針對 這些議題,本論文提出以資源導向架構風格來改良 CWMP,並針對現行各 種 Web Callback 機制做實驗與分析,評估適合 CWMP 應用場域中的 Callback 機制,基於上述機制,建構基於資源導向架構的 CWMP 智慧家庭服務維運 平台,並透過實驗與實作應用情境,並驗證其功能完備性、效能及實務上 之可行性。 / The vision of smart home has been depicted for over a half-century. Nevertheless, Smart Home technologies are still not widely deployed in most people’s living spaces. The main reason is that operations management technologies for smart home such as remote deployment, monitoring, and maintenance are not well studied and only a few attempts have so far been made toward this aspect. CWMP, proposed by Broadband Forum, is a promising standard for realizing a Smart Home operations management platform. Several design issues, namely, poor performance and scalability, poor domain model design and inappropriate web callback architecture, have been identified. The objective of this thesis is, therefore, to deal with the issues mentioned above by suggesting a set of new ways to design CWMP functionalities. The overall approach is based on the RESTful architectural style. Finally, the proposed designs are realized as an operations management platform prototype. Validations and experiments are performed to verify the effectiveness of the proposed approach.

Aide à la décision pour la planification des activités et des ressources humaines en hospitalisation à domicile / Decision support for planning the operations and the human resources in Home Health Care services

Redjem, Rabeh 08 July 2013 (has links)
L’hospitalisation hors les murs est une expression générique qui désigne toutes les formes de structures accueillant des patients pour une prise en charge longue et régulière nécessitant des soins complexes. Les structures hors les murs doivent assurer une prise en charge sure et d’une qualité au moins identique à celle fourni par l’hôpital, tout en contribuant à la diminution des coûts de la prise en charge. D’où la nécessité d’une gestion efficiente des activités des soignants et des ressources humaines. Dans ce travail de recherche, l’intérêt est porté à la problématique générale de gestion des activités de soins en Hospitalisation À Domicile (HAD). Il s’agit d’une problématique très complexe, car elle vise à résoudre simultanément des sous-problèmes réputés NP – difficiles. Dans cette thèse, nous étudions cette problématique au niveau opérationnel de la conception des tournées des soignants. La démarche adoptée pour ce travail de recherche se base sur trois étapes essentielles. Nous commençons par une étude sur le système de santé et les structures d’HAD en France, tout en mettant en claire les facteurs essentiels de leur fonctionnement. Cette étape sera clôturée par une étude du fonctionnement des systèmes d’HAD dans la région Rhône-Alpes, en se basant sur les retours du projet régional Organisation des Soins A Domicile (OSAD). La deuxième étape concerne les problématiques de gestion et la planification des activités de soins et des ressources humaines en HAD. Ce travail conduira à l’élaboration d’une classification des problématiques de la gestion des activités en HAD. En se basant sur la classification identifiée précédemment, nous définissons, les axes de complexité de ce problème : (i) le nombre d’activités de soins par soignant, (ii) la dépendance temporelle entre les activités des patients et (iii) la dimension environnementale. Ensuite, nous proposons un ensemble d’approches et d’outils pour la résolution de la problématique des tournées d’infirmiers en HAD, sous différentes contraintes liées à la réalisation des soins et en particulier aux contraintes de dépendances temporelles. Pour répondre à l’ensemble des contraintes et exigences de performance, nous développons une heuristique originale permettant une résolution en un temps compatible avec les contraintes de mise en oeuvre, pour des instances de grande taille / Home care services, is a generic term that gathers different kind of care: provider, agency, and organization. In France, the most important part of the in-home care is performed by HAD (Hospitalization At Home). The HAD concept is defined by decree. The HAD has to provide only complex care in the patient’s home for 24 motives. HAD are hospitals and have to ensure continuity of care for their patients. Our researches focus on the operation management for home care services. This problem is complex; it needs to solve sub-problems known to be NP - hard. In this work, this problem is studied at the operational level in design of tours of caregivers. The approach followed is based on three essential stages. Firstly, we study the health system and the home care structures in France. At the end of this step, we summarize the outcome obtained of the regional project Organization of Home Care Service (Organisation des Soins A Domicile : OSAD) on the home care structures in the Rhône-Alpes region (France). The second step gathers scientific literature about home care management, particularly about problems of management and planning of activities and human resources in the home care structures. This work leads to design a classification in order to management activities issues in home care structures. Based on this classification, we define three complexity axes of the operation management in home care problem, i.e. (i) the rate of the number of care activities per caregiver, (ii) dependency level between the patients’ activities and (iii) the environmental level. In the third stage, we suggest a set of mathematical approaches and tools for solving the problem of caregivers’ tours. Two MIPL model are developed, the first is based on a Traveling Salesman Problem (TSP) with coordination between the caregivers and the second on RCPSP (Ressources Constrained Project Scheduling Problem). Because the both previous models are time consuming, we suggest an original heuristic to solve the TSP coordinated problem, to resolve the care management activities in home care services

Chefers informationsinsamling under distansarbete : En jämförande studie av produktionsledning och administrativ ledning

Lundell, Tobias, Vallgren, Mattias January 2021 (has links)
Studiens syfte är att frambringa en ökad förståelse kring chefers informationsinsamling under distansarbete genom en jämförelse mellan två chefsgrupper inom olika verksamhetsområden. Chefsgrupperna utgörs av dels chefer inom produktionsledning och chefer i en administrativ ledning. Intentionen med en jämförande studie är att åskådliggöra skillnader i vilka alternativa tillvägagångssätt chefsgrupperna tillämpar i informationsinsamlingen under distansarbete. Tidigare forskning har avhandlat grunderna i chefsarbete samt chefsarbete på distans. Den aktuella studien fokuserar på chefsarbete under distansarbete via en jämförande karaktär där studien identifierat ett aktuellt forskningsgap. En jämförande studie är relevant för att åskådliggöra hur chefsgrupperna agerat vid omställningen mot distansarbete eftersom arbetet vanligtvis inte utförts på distans tidigare. Eftersom cheferna arbetar inom olika verksamhetsområden är det av intresse att belysa vilka skillnader som kan utläsas mellan grupperna. Studien tar sin utgångspunkt i den deduktiva ansatsen via kvalitativa intervjuer utförda med åtta stycken chefer inom olika företag fördelade på två chefsgrupper.  Resultatet påvisar att det existerar skillnader i tillvägagångssätten kring informationsinsamling för de olika cheferna. Från cheferna i produktionsledning kan urskiljas att ett delegerat arbetssätt varit ett genomgående förekommande tillvägagångssätt vilket effektiviserat informationsflödena och informationsinsamlingen inom organisationerna. En tydlig distinktion gentemot chefer inom den administrativa chefsgruppen är att cheferna inom den senare kategorin anammat ett större fokus på att utforma procedurer för att göra den digitala mötesformen mer effektiv och välfungerande. Anledningen är att det digitala formatet utgör det huvudsakliga forumet för att delge och samla in information under distansarbete. Skillnaden i tillvägagångssätt utgörs av de underordnades roll och arbetsuppgifter inom organisationerna. Eftersom de anställda som lyder under produktionsledningen fortsättningsvis behövt befinna sig fysiskt på arbetsplatsen för att upprätthålla verksamheten har cheferna modifierat ett arbetssätt anpassat efter förutsättningarna. Inom den administrativa gruppen har både chefer och anställda möjlighet att bedriva arbetet från distans vilket ställt krav på cheferna att finna effektiva tillvägagångssätt kopplat till digitala kommunikationsverktyg för att skapa förutsättningar att kunna samla in information om verksamheten. / The purpose of the study is to generate an increased understanding of managers' information gathering during telework through a comparison between two management groups in different business areas. The management groups consist of managers within operations management and managers in administrative management. The intention of a compared study is to visualize differences in which alternative approaches the management groups apply in the information gathering during teleworking. Previous research has discussed the premises of managerial work and managerial work during telework. The current study focuses on managerial work during telework via a comparison where the study identified a current research gap. A comparative study is essential to illustrate how the management groups have acted in the transition to telework, as the work has usually not been performed remotely before. Since the managers work in different areas of activity it is interesting to highlight the differences that can be read between the groups. The study is based on the deductive approach via qualitative interviews accomplished with eight managers in different companies divided into two management groups. The results show that there are differences in the approaches to information gathering for the various managers. In operations management it can be distinguished that a delegated method has been a common procedure, which has streamlined the information flows and information gathering within the organizations. An explicit distinction towards managers within the administrative management group is that the managers within the latter category have adopted a considerable focus on forming procedures to make the digital form of meeting more efficient and well-functioning. The reason is that digital communication is the main forum för communicating and gathering information during telework. The difference in approach consists of the role and tasks of the subordinates within the organization. As the employees who are under the operations management continued to need to be physically at the workplace to maintain the business, managers have modified a way of working adapted to the conditions. Within the administrative group both managers and employees have the opportunity to conduct the work remotely, which requires managers to find effective procedures linked to digital communication tools to create conditions for being able to gather information about the organization.
