Gestão de portfólio de serviços de MRO (Maintenance, Repair and Overhaul) aeronáutico: uma pesquisa ação / Portfolio management service MRO (Maintenance, Repair and Overhaul) aircraft: an action research

Luiz Gabriel Rossi Roque 14 September 2012 (has links)
Os centros de manutenção de aeronaves da América Latina possuem portfólios de serviços limitados e esse é um fator que restringe o crescimento do transporte aéreo na região. Faz-se necessário, portanto, o desenvolvimento de novos serviços de reparo de aeronaves e seus componentes nesses centros. Apesar de o Desenvolvimento de Produtos ter recebido uma atenção substancial na ultima década, há pouca literatura sobre o Desenvolvimento de Serviços e trabalhos que tratam de gestão de portfólio de serviços são ainda mais escassos. A pouca literatura existente não é suficientemente abrangente para tratar da gestão de portfólio de serviços de manutenção complexa. O objetivo deste trabalho é, portanto, desenvolver um processo de gestão de portfólio de serviços para empresas de manutenção aeronáutica, chamado de modelo específico. O desenvolvimento do modelo será feito utilizando a pesquisa-ação, abordagem que objetiva tanto a tomada de ação quanto a criação de conhecimento com ciclos contínuos. Durante a criação do modelo específico foram usados como base de conhecimento modelos de referência de PDP e PDS, posteriormente adaptados para a realidade de serviços, para a região e tipologia da indústria. A pesquisa ação se iniciou numa pré-fase de contextualização, seguida por quatro ciclos, sendo que em cada ciclo uma etapa do modelo foi desenvolvida e avaliada, resultando em um modelo especifico de gestão de portfólio para indústria de MRO aeronáutico brasileiro. Ao final dos ciclos foi feita uma avaliação do processo criada por meio de um questionário. Os participantes da pesquisa avaliaram o método de desenvolvimento do modelo como adequado e avaliaram também o próprio modelo como adequado. / The aircraft maintenance centers in Latin America have limited portfolios of services; this is a factor that restricts the growth of air transport in the region. Therefore is necessary to develop new maintenance, repair and overhaul (MRO) services for aircraft and their components in those centers. New Product Development (NPD) process theory has received substantial attention in the last decade but there is little literature on the New Services Development (NSD), and papers dealing directly with services portfolio management are even scarcer. The existing literature is not holistic enough to deal with maintenance services portfolio management. Therefore this paper aims to develop a services portfolio management (SPM) for aircraft components maintenance. The SPM model development will be done using the action research approach trough the creation of knowledge in continuous PDCA cycles. During the creation of the specific model, were used as knowledge base reference models of PDP and PDS, later adapted to the reality of services to the region and type of industry. The action research began in pre contextualization phase, followed by four cycles, and each cycle a stage of the model was developed and evaluated, resulting in a specific model of portfolio management for MRO Brazilian aeronautics industry. At the end of cycles an evaluation process created by means of a questionnaire. Survey participants rated the method as proper development of the model, the model itself also rated as adequate.

Opportunities and challenges for mainstreaming ecosystem services in decision making

Sitas, Nadia 12 1900 (has links)
Thesis (PhD)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: Ecosystem service research has grown significantly in recent years, highlighting links between ecosystem services and human well-being. Few studies are however, geared towards providing user-friendly, user-useful and user-relevant information suitable for implementing effective local management of areas that deliver ecosystem services, resulting in a gap between ecosystem service research and management. In response to this challenge, it has been argued that in order to safeguard the benefit flows provided by ecosystems, the concept of ecosystem services should be mainstreamed into land-use (and water-use) planning and management processes. As the conservation of ecosystem services is ultimately a social process operating in a social context, understanding the complexity of the research-management interface demands input from a range of stakeholders. Thus, mainstreaming the environment into decision making requires multi-stakeholder engagement processes that facilitate the co-production and exchange of knowledge. Accordingly, through the use of a transdisciplinary, mixed method approach, this dissertation contributes to a better understanding of some of the opportunities and challenges for mainstreaming ecosystem services in development planning at a local level, using a case study in the Eden District (Eden) of South Africa. Through an extensive stakeholder engagement process which explored what the information needs, responsibilities and capacities of decision makers in Eden are, both opportunities that facilitate the integration of ecosystem service information in decision making, and challenges impeding integration, have been identified. This research found that despite a history of ecosystem service research in Eden, there has been limited integration of the concept of ecosystem services into decision-making processes driving development. Insufficient capacity, limited resources, minimal proactive planning, a weak regulatory environment, entrenched disciplinary thinking and insufficient communication amongst diverse stakeholders on the benefits of using an ecosystem-based approach remain as challenges for the mainstreaming of ecosystem services in decision making. However, strategic opportunities for mainstreaming ecosystem services into decisions regarding current and future development trajectories were also found. It was found that the development, and nurturing of transdisciplinary learning networks that are problem driven, and action oriented, using a communities of practice model of engagement, can facilitate legitimate knowledge exchange processes. In this regard, the role of individual and institutional knowledge brokers was found to be critical. It was also found that the concept of risk was useful as a mainstreaming tool in bridging the gaps between different disciplines, and between science, policy and practice. A frame of risk enabled different disciplinary and knowledge communities to participate in joint activities and discussions during which information was co-produced and exchanged. Through this work, new relationships were built that facilitated both learning and action with regards to the importance of ecosystem services for mitigating risk. / AFRIKAANSE OPSOMMING: Ekosisteemdiens-navorsing het aansienlik gegroei in die afgelope jare, met ‘n klem op die verband tussen ekosisteemdienste en menslike welsyn. Min ondersoeke is egter gerig op die verskaffing van gebruikersvriendelike, -nuttige en -relevante inligting wat geskik is vir die implementering van doeltreffende plaaslike bestuur van die gebiede wat ekosisteemdienste lewer, en dit lei tot 'n gaping tussen ekosisteemdiens-navorsing en -bestuur. In reaksie op hierdie uitdaging word aangevoer dat ekosisteemdienste gehoofstroom moet word in prosesses ter beplanning en bestuur van grond- en watergebruik, ten einde die voordele wat deur ekosisteme gebied word, te beskerm. Omdat die behoud van ekosisteemdienste per slot van rekening `n sosiale proses is wat in `n sosiale konteks in werking is, word insette van 'n verskeidenheid van belanghebbendes vereis, om die ingewikkelde aard van die koppelvlak tussen navorsing en bestuur te verstaan. Dus, om die omgewing in besluitneming te hoofstroom, vereis prosesse van betrokkenheid van veelvuldige belanghebbendes, wat die medevervaardiging en uitruil van kennis fasiliteer. Gevolglik, deur die toepassing van `n transdissiplinêre, gemengde metode benadering in `n gevallestudie in die Eden Distrik (Eden) van Suid-Afrika, dra hierdie verhandeling by tot `n beter begrip van sommige van die geleenthede en uitdagings verbonde aan die hoofstroming van ekosisteemdienste in ontwikkelingsbeplanning op 'n plaaslike vlak. Deur `n uitvoerige proses van deelname met belanghebbendes is inligting benodig deur besluitnemers in Eden, sowel as hul verantwoordelikhede en vermoëns, verken, en sodoende is beide die geleenthede wat die integrasie van ekosisteemdiens-inligting in besluiteming fasiliteer, en uitdagings wat integrasie belemmer, geïdentifiseer. Hierdie navorsing het bevind dat, ten spyte van `n geskiedenis van ekosisteemdiens-navorsing in Eden, is daar beperkte integrasie van die konsep van ekosisteemdiens in besluitnemingsprosesse wat ontwikkeling dryf. Onvoldoende kapasiteit, beperkte hulpbronne, minimale proaktiewe beplanning, 'n swak reguleringsomgewing, verskanste dissiplinêre denkwyses en onvoldoende kommunikasie tussen uiteenlopende belanghebbendes oor die voordele verbonde aan die gebruik van 'n ekosisteembenadering, bly uitdagings vir die hoofstroming van ekosisteemdienste in besluitneming. Maar strategiese geleenthede vir die hoofstroming van ekosisteemdienste in besluitneming in verband met huidige en toekomstige ontwikkelingsbane is ook aangetref. Daar is bevind dat, deur transdissiplinêre leernetwerke wat probleemgedrewe en aksie-georiënteerd is, te ontwikkel en koester met behulp van 'n praktykgemeenskappemodel van betrokkenheid, legitieme kennisuitruilingsprosesse gefasiliteer kan word. In hierdie verband is die rol van individuele en institusionele kennismakelaars as krities bevind. Daar is ook bevind dat die konsep van risiko nuttig is as 'n hoofstromings-instrument in die oorbrugging van die gaping tussen die verskillende dissiplines, en tussen wetenskap, beleid en praktyk. `n Raamwerk van risiko het verskillende dissiplinêre en kennisgemeenskappe in staat gestel om deel te neem aan gesamentlike aktiwiteite en besprekings, waartydens inligting saam geproduseer en uitgeruil is. Deur hierdie werk is nuwe verhoudings gevestig, wat beide leer en optrede rakende die belang van ekosisteemdienste vir risikotempering gefasiliteer het.

Rodrigues, Kênia Fernandes de Castro 06 August 2014 (has links)
No contexto da avaliação econômica de projetos de desenvolvimento de produtos e serviços percebem-se muitas dificuldades: ausência de classificação dos métodos de avaliação de investimentos apropriados para o contexto de priorização e seleção de projetos; ausência de sistematização das condições necessárias (conhecimentos, informações, habilidades, formulações e critérios de avaliação) à aplicação dos métodos; ausência de um framework de avaliação econômica que integre condições necessárias para a aplicação dos métodos com o apoio à escolha e aplicação de métodos de avaliação de investimentos apropriados aos conhecimentos disponíveis. Com o objetivo de superar tais dificuldades, essa pesquisa propõe uma sistematização e análise da avaliação econômica de projetos de desenvolvimento de produtos e serviços para poder apoiar a escolha e aplicação de métodos. O método de pesquisa adotado consiste em múltiplos estudos de casos. A pesquisa compreende três fases: (1) Aquisição de conhecimentos; (2) Sistematização da avaliação econômica, com base na revisão bibliográfica e em pesquisa de campo exploratória; (3) Análise da avaliação econômica com base em sete casos. Os resultados colaboram com evidências de que uma sistematização da avaliação econômica pode apoiar a escolha e a aplicação de métodos de avaliação de investimentos para a priorização e seleção de projetos de desenvolvimento de produtos e serviços conforme os conhecimentos disponíveis. Além disso, uma proposta de planilha e a simulação de um exemplo fictício foram elaboradas, com o objetivo de apoiar a avaliação de projetos de desenvolvimento de produtos e serviços. Os resultados compreendem desde a caracterização e sistematização dos métodos de avaliação de investimentos na priorização e a seleção de projetos de desenvolvimento de produtos e serviços, a análise de diversos constructos chaves em estudos de casos, até a proposição de possíveis melhorias do processo decisório nos casos. / In the context of economic evaluation, many difficulties are perceived: lack of classification of evaluation methods according to the context of investment prioritization and selection of projects to develop products and services; lack of systematization of the required conditions (knowledge, information, skills, formulation and evaluation criteria) to the applications of methods; lack of economic evaluation framework that integrates the required conditions to support the choice of methods to apply according to the available knowledge. In order to overcome these difficulties, this research proposes a systematization and analysis of the economic evaluation of the product and service development projects to support the methods choice and selection. The research method adopted is based on multiple case studies. The research comprehends three phases: (1) Acquisition of knowledge; (2) Economic evaluation systematization, through literature review and exploratory field research; (3) Analysis of the economic evaluation based on seven cases. The results provide evidence that a systematization of economic evaluation can support the choice and application of valuating investments methods for the prioritization and selection of the product and service development projects according to the available knowledge. Furthermore, a proposal of a spreadsheet and its simulation based on a fictional example were prepared, aiming at supporting the evaluation of development projects for products and services. The results comprises from the characterization and systematization of the methods to evaluate investments concerning the prioritization and selection of projects for development of products and services, the analysis of several key constructs in case studies, to the proposition of possible improvements in the decision-making in those cases.

A proposed water sector plan for the Dr Kenneth Kaunda District Municipality / M. Diedericks.

Diedericks, Melvin January 2013 (has links)
The recent reform of potable water service provisioning by means of the promulgation of the Water Services Act 108 of 1997 and the National Water Act 36 of 1998 in South Africa has started a process of addressing the imbalance that existed in regard to how the national resource was being distributed. Water is now recognised as a scarce resource that belongs to all the people of the country. Consequently, it should be managed in an integrated way for social and economic development – including future growth (Fuggle & Rabie, 2005:293; Reimann, Chimboza & Fubesi, 2012:446). What is required is an attitude that incorporates a sensitivity in the careful cognisance and management of ―the aggregate of surrounding objects, conditions, and influences that impact on the life and habits of man, or any other organism or collection of organisms (South Africa, 1989). The provision of potable water by water services authorities (WSAs) is an important basic service that faces a number of challenges, such as the use of an outdated infrastructure, the lack of skilled and knowledgeable people, improper planning, and the booming population that places overt pressure on the demand for service delivery. This study was, therefore, undertaken to investigate how a municipality – which is forced to obtain its potable water supply from nearby surface and groundwater catchments, could manage this supply in a more effective, efficient, equitable, economic and sustainable manner by means of improved co-operative governance and intergovernmental relations. The key motivation was thus to develop a plan that would manage water resources more effectively on strategic, tactical and operational levels within government structures and to assist in realising integrated water resources management (IWRM). The proposed plan could be used to develop a shared vision for the Dr Kenneth Kaunda District Municipality (Dr KKDM) municipal area of responsibility; and to provide an overview of the strengths, weaknesses, opportunities and threats regarding the management of water resources. A qualitative research design was used to conduct the study, which included a literature review, semi-structured interviews, data sampling and scientific analysis of responses. Furthermore, a case-study approach was followed by the researcher, with Dr KKDM as the unit of analysis (the locus). / Thesis (Ph.D. (Public Management and Governance))--North-West University, Potchefstroom Campus, 2013.

Předpoklady rozvoje komerčních služeb ve vybrané oblasti - Dobrovolný svazek obcí Zlatý vrch / The Assumptions of Commercial Services Development in a Chosen Area - DSO Zlaty vrch

VLKOVÁ, Jana January 2011 (has links)
The aim of this thesis is to analyse commercial servises in the area Zlatý vrch and suggest the possible solutions of their develepment. The literary part, in which the basic terms of the topic are characterized, was written first. These terms are then used in the practical part. Subsequently, the situation analysis, where the whole territory is mapped, was worked out. Futhermore, the survey of the businesmen and also interwiews with the mayors of each municipality were carried out. SWOT analysis of strengths, weaknesses, opportunities and threats was prepared on the basis of these analyses. At the end, I proposed my own suggestions for the expansion of commercial services, which arise from the three main priorities: turism, business and environment.

Entretanto, ela ainda não oferece apoio para tratar as características não-funcionais dos serviços. Os consumidores de serviços Web podem requerer serviços com parâmetros de qualidade específicos e esperar garantias de níveis de qualidade. O objetivo desta dissertação é estender o modelo de serviços Web para apoiar a gerência de características não-funcionais para serviços Web. O modelo proposto inclui mediadores para auxiliar na descoberta de serviços de acordo com os requisitos funcionais e não-funcionais dos consumidores e monitores para verificar os atributos de qualidade. As principais contribuições desta dissertação são: a utilização do padrão Web Services Policy Framework (WS-Policy) para complementar as descrições de serviços Web Services Description Language (WSDL) com políticas para atributos de qualidade; uma extensão para o padrão Universal Description Discovery & Integration (UDDI) para a publicação e a descoberta de serviços Web incluindo características nãofuncionais; e o monitoramento e a atualização de características não-funcionais para refletir os atributos reais dos serviços / Abstract: Although the Web service technology allows the development and execution of distributed applications, it still lacks facilities to deal with Quality of Service (QoS). Consumers may require services with particular non-functional characteristics and expect quality level guarantees. The goal of this thesis is to propose an extended Web service architecture supporting QoS management for Web services. It includes brokers to facilitate service selection according to functional and non-functional requirements and monitors to verify QoS attributes. The main contributions of this approach are: the use of the Web Services Policy Framework (WS-Policy) standard to complement Web Services Description Language (WSDL) specifications with QoS policies; an extension to the Universal Description Discovery & Integration (UDDI) standard for QoS-enriched Web service publication and discovery; and QoS updating to reflect actual service attributes / Mestrado / Mestre em Ciência da Computação

LEONARDO PEREIRA RODRIGUES DOS SANTOS 12 November 2003 (has links)
[pt] O propósito deste trabalho é analisar as características relevantes dos cursos de mestrado em administração e em que grau elas são avaliadas por seus alunos e ex-alunos, com o objetivo de fornecer subsídios para as instituições acadêmicas desenvolverem ou aprimorarem tais cursos. Nesta pesquisa, aplicou-se a teoria de análise conjunta, a fim de se apontar o conjunto de características consideradas relevantes pelos estudantes de cursos de mestrado em administração de empresas. O desenvolvimento da dissertação foi composto de duas etapas: escolha dos atributos e níveis a serem avaliados pelos respondentes e análise dessa avaliação. Para escolher o conjunto de atributos e níveis a serem julgados, foram analisadas as informações existentes na literatura e conduzido um grupo de foco. Em seguida, foi escolhido o conjunto de estímulos a ser submetido aos estudantes de mestrado, desenvolvido com base no projeto ortogonal calculado pelo software estatístico SPSS. Realizou-se, então, a coleta de dados por meio de questionários, os quais foram entregues pessoalmente aos entrevistados ou enviados, em alguns casos, via correio eletrônico. Na última etapa, analisaram-se, com o auxílio do software SPSS, as importâncias relativas dos atributos e utilidades dos níveis propostos na pesquisa de campo, o que propiciou que o objetivo geral de se identificarem as características relevantes para conceito de um curso de mestrado fosse alcançado. / [en] The purpose of this work is to identify the main features of the Master in Business Administration programs and how these programs are evaluated by students and former students, aiming at helping academic institutions develop or improve their Master degree courses in the area. In this research, the conjoint analysis method was used to determine the set of features considered relevant by Master in Business Administration students. The thesis was developed in two stages: choosing the attributes and levels to be evaluated by respondents and analyzing such evaluation. The attributes and levels to be assessed were chosen only after the existing information was analyzed and a focus group was conducted. The set of stimulis to be given to the Master in Business Administration students was then chosen based on the orthogonal project calculated by the statistical software SPSS. The next stage involved data collection using questionnaires, which were personally delivered to the respondents or, in some cases, sent by e- mail. Finally, the statistical software SPSS was used to analyze the relative importance of the attributes and the partial utilities of the levels proposed in the field research, achieving the general goal of identifying the relevant features for the concept of a Master´s degree course.
