Organização de conhecimento e informações para integração de componentes em um arcabouço de projeto orientado para a manufaturaRamos, André Luiz Tietböhl January 2015 (has links)
A constante evolução de métodos, tecnologias e ferramentas associadas na área de projeto fornece maior capacidade para o projetista. Entretanto, ela também aumenta os requisitos de interfaces e controle do conjunto de componentes de projeto consideravelmente. Tipicamente, este aspecto está presente na área de Projeto Orientado para a Manufatura (DFM) onde existem diversos distintos componentes. Cada um dos componentes existentes, ou futuros, pode ter foco diferente, consequentemente com requisitos de informação, utilização e execução distintos. Este trabalho propõe a utilização de padrões conceituais flexíveis de informação e controle de forma abrangente em uma arquitetura de Projeto Orientado para a Manufatura (DFM). O objetivo principal é auxiliar a análise e resolução de DFM, bem como dar suporte à atividade de projeto estruturando e propondo uma solução em relevantes aspectos em DFM: estruturação do contexto das informações (ou conhecimento) em DFM. A arquitetura utiliza as seguintes atividades de projeto em processos de usinagem: Tolerância, Custo, Acessibilidade da ferramenta, Disponibilidade de máquinas e ferramentas e Análise de materiais para demonstrar a relevância da correta contextualização e utilização da informação no domínio DFM . Sob forma geral, concomitantemente, as amplas necessidades de compreensão dos distintos tipos e formas da informação em DFM demandam que uma arquitetura de projeto tenha capacidade de gerenciar/administrar diferentes contextos de informações de projeto. Este é um tópico relevante tendo em vista que existem diferentes atividades DFM que eventualmente devem ser incluídas no ato de projetar. Tipicamente, cada uma delas tem requisitos distintos em termos de dados e conhecimento, ou contextualização do projeto, que idealmente poderiam ser gerenciados através da arquitetura de informação atual – STEP.Aarquitetura proposta gerencia contextos de informações de projeto através de ontologias direcionadas no domínio DFM. Através dela, será possível compreender e utilizar melhor as intrínsecas interfaces existentes nas informações deste domínio, além de, através disto, aumentar a flexibilidade e eficácia de sistemas DFM. / This work proposes the use of industry standards to support the utilization of Design for Manufacturing (DFM) techniques in a comprehensive scale in the design field. The specific aspect being considered in an architecture is the definition and structure of DFM information context. In order to demonstrate the research concepts, some design activities are implemented the framework (which is focused in machining processes): Tolerancing model, Cost model based on material remove processes, Tool Accessibility model taking into consideration the part being designed, Availability of Machines and Tools model, and Material analysis. The broad needs of design–based frameworks, in general, require that its architecture must have the capabilities to handle di erent framework design information utilization contexts, or information context concepts. This is a relevant aspect since there are severalDFMcomponents/activities that preferably should be included in the design process. Traditionally, each one of them might have distinct data & knowledge requirements, which can be handled by the current information architecture – STEP – only in part. Additionally, each one of them might have, or need, di erent forms of understanding DFM information (information context). The framework handles information context concepts through the use of the ontologies targeted to the DFMfield. It is expected that a better comprehension and usage of the intrinsic information interfaces existent in its domain be achieved. Through it, more flexible and e ective DFM systems information-wise can be obtained.

Supporting At-Risk Students Through the Interconnected Systems Framework: Perspectives of Specialized Instructional Support PersonnelSandoval, Luis Angel 01 January 2024 (has links) (PDF)
The number of students with mental health challenges has increased significantly in public schools during the past 10 years. Despite school and community efforts many students remain underserved, specifically at-risk populations. At-risk youth are more likely to experience adverse life outcomes such as performing poorly in school, dropping out of school, acting violently, and facing higher instances of mental health challenges when compared to peers with fewer risk factors. The purpose of this qualitative study was to examine specialized instructional support personnel’s attitudes and willingness to implement a change model, ISF, to support at-risk youth in the public school system. A secondary aim of this study was to answer the question of the attitudes of specialized instructional support personnel to provide insight for decision makers considering adopting this change model. The research question posed was: What are specialized instructional support personnel’s attitudes toward implementing a mental health change model, ISF, in their school district? This study also contributed to furthering the knowledge of a complex service delivery system intended to enhance student performance by identifying support structures that promote student wellness. The results of this study indicated the specialized instructional support personnel interviewed would be willing to support elements of the ISF.

Styrning mot målkongruens när outsourcing tillämpas : En kvalitativ fallstudie på Eksjöhus AB / Control towards goal congruence when outsourcing is applied : A qualitative case study at Eksjöhus ABKågebrand Karlsson, Matilda, Johansson, Frida, Nelzén, Ebba January 2020 (has links)
Bakgrund och problem: Ekonomistyrning måste anpassas till respektive företags förutsättningar. Företag kan tillämpas olika strategier i syfte att uppnå deras vision varav en strategi är outsourcing. Outsourcing innebär att en extern part kontrakteras att utföra en viss aktivitet för en annan organisations räkning. Denna form av struktur får dock inverkan på verksamhetens förmåga att skapa målkongruens eftersom det innebär att även den externa partens målsättningar måste stämma överens med organisationens målsättningar. Ytterligare problematik uppstår när outsourcing tillämpas till flertalet externa organisationer i form av agenter. Problematik i förhållandet mellan agenten och den styrande verksamheten beskrivs i teorin av fenomenet agency theory och dess underliggande antagande om att respektive part kommer att agera utefter sina egna intressen och målsättningar. Att styra en verksamhet till målkongruens under dessa förutsättningar blir därmed komplext. Syfte: Studien ämnar förklara komplexiteten i styrning när outsourcing tillämpas på en avdelning som består av agenter. Utöver detta ska studien också beskriva hur styrning implementeras och vilka styrmedel som appliceras för de olika avdelningarna inom fallföretaget i jämförelse med den outsourcade avdelningen. Studien syftar därmed till att undersöka hur styrning kan utformas för att uppnå målkongruens i en verksamhet inom husbyggnadsbranschen som har valt att tillämpa outsourcing på försäljningsavdelningen. Metod: Studien har tagit ansats i en kvalitativ forskningsmetod och tillämpat en enfallsstudie som forskningsdesign. Vidare har insamlingen av det empiriska materialet utgått från semistrukturerade intervjuer. Slutsats: Styrning mot målkongruens när outsourcing tillämpas uppnås genom att respektive avdelnings samt individers målsättningar sammanlänkas med organisationens målsättningar, vilket också överensstämmer med vad teorin definierar som tillvägagångssätt för att uppnå målkongruens. I syfte att den externa organisationen ska tillta ett målkongruent beteende bör vinstmaximering ligga till grund för utformningen av eventuell budget och målsättning i den outsourcade verksamheten. / Background and problem: Management control must be adapted to the circumstances of each company. Companies can apply different strategies to achieve their vision, one being outsourcing. Outsourcing means that an external party is contracted to perform a certain activity on behalf of another organization. However, this form of structure has an impact on the business's ability to create target congruence because it means that the external party's objectives must be in line with the organisation's objectives. Further problems arise when outsourcing is applied to multiple external organizations in the form of agents. Problems within the relationship between the agent and the business that controls are described as the phenomenon of agency theory and its underlying assumption that each party will act according to its own interests and objectives. Controlling a business to target congruence under these conditions is thereby complex. Purpose: The study aims to explain the complexity of control when outsourcing is applied to a department that consists of agents. In addition to this, the study will also describe how control is implemented and how control mechanisms are applied to the various departments within the case company in comparison to the outsourced department. The aim of this study is thereby to investigate how control can be designed to achieve target congruence in an activity in the house construction industry that has chosen to apply outsourcing to the sales department. Method: The study has taken a qualitative research and applied a case study as a research design. Furthermore, the collection of the empirical material has been based on semi- structured interviews. Conclusion: Control towards goal congruence when outsourcing is applied is achieved by linking the objectives of each department and individuals with the goals of the organization. This is also in line with what the theory defines as the approach to achieving goal congruence. In order to achieve a goal-congruent behaviour, the external organization should use of profit maximization in every budget and objectives in the outsourced activity.

Applying the "safe place, safe person, safe systems" framework to improve OHS management: a new integrated approachMakin, Anne-Marie, Safety Science, Faculty of Science, UNSW January 2009 (has links)
A new model was developed to enhance the understanding of the full context of work associated hazards, to explore the connection between OHS performance and a systematic approach to safety, and to simplify approaches to OHS management. This Safe Place, Safe Person, Safe Systems model was derived from the literature and used as the basis for the development of a framework, consisting of 60 elements which was transformed into an assessment tool. This assessment tool was trialled with a pilot study on a medium sized manufacturing plant in the plastics industry, and the tool and Preliminary Report peer reviewed by an expert panel using the Nominal Group Technique. After refinements were made to the assessment tool it was applied to eight case studies that were drawn from advertisements. This qualitative study consisted of two parts: firstly the assessment using the Safe Place, Safe Person, Safe Systems framework; and secondly a controlled self assessment exercise to target improvements to three of the elements over a period of four months. The study illustrated that the Safe Place, Safe Person, Safe Systems framework could be successfully applied in a range of industries to promote OHS improvements and to provide a systematic, planned approach to fulfilling OHS responsibilities. The application of this framework highlighted that: there is a need for further education on the correct application of the risk assessment process and the responsibilities owed to contractors; techniques such as dynamic risk assessments are more suitable where the place of work is variable and hazards are unpredictable; more focus is needed on the appropriate management of hazardous substances with long term health consequences; and that the level of formality invoked for treating hazards does not necessarily equate to improved risk reduction outcomes. The Safe Place, Safe Person, Safe Systems framework was found to be applicable to small, medium and large organisations provided the assessment was scoped to a small division of relatively homogeneous activity to ensure a more representative hazard profile. This approach has provided a way forward to simplify OHS management and also offers practical direction for implementing a targeted OHS improvement program.
