Arquitetura de sistema de planejamento e controle da produção no contexto de empresa virtual. / Production planning and control system architecture in virtual enterprise context.

Marcosiris Amorim de Oliveira Pessoa 24 April 2015 (has links)
Em um mercado global, tem sido observada a tendência para a dispersão geográfica das fabricas. Esta dispersão e motivada pela oportunidade de explorar as vantagens locais, sob diferentes pontos de vista. Essa estrutura também permite a interação mais intensa entre plantas de diferentes empresas produtivas. Neste sentido, o conceito de Empresa Virtual (EV) e fundamental para explorar novas estratégias de negócios, tais como foco nas competências essenciais, orientação máxima para o cliente e produção distribuída. No entanto, nesta nova estrutura produtiva, há novos requisitos para o planejamento e para o estabelecimento da data de entrega dos pedidos. Um sistema de Planejamento e Controle da Produção (PCP) convencional utiliza uma arquitetura hierárquica, o que não atende o requisito de autonomia das empresas parceiras. Para atender a essas novas exigências, este trabalho apresenta uma arquitetura de sistemas de planejamento e controle da produção no contexto de EV. Na proposta são utilizados os conceitos de janelas de tempo em conjunto com propagação de restrições para atender os requisitos de prazo de entrega de produtos. Estes dois conceitos tem sido amplamente utilizados na literatura relacionada a sistemas de planejamento convencionais, no entanto, não no contexto de EV. Nesta abordagem, as janelas de tempo delimitam o intervalo de alocação das tarefas nos sistemas de produção envolvidos, enquanto as restrição de capacidade identificam janelas de tempo factíveis considerando a importância da data de vencimento do pedido. E apresentado um exemplo da utilização da arquitetura e um exemplo de implementação. Este trabalho engloba EVs com empresas parceiras de diversos tipos de produção (produção em lotes e produção discreta). E utilizado o Production Flow Schema (PFS) para modelagem dos processos produtivos segundo uma abordagem hierárquica, com base em sucessivos renamentos para construir o modelo de forma progressiva e estruturada onde as propriedades do modelo ficam asseguradas por construção. Este refinamento gera sub-grafos em Rede de Petri, que são utilizados para a analise e o controle do processo produtivo. / In a global market, the trend for geographical dispersion of manufacturing plants has been observed. This dispersion is motivated by the opportunity to exploit local advantages under dierent viewpoints. This structure also allows for more intense interaction between plants of dierent productive enterprises. In this sense, the concept of Virtual Enterprise (VE) is fundamental to explore new business strategies such asfocus on core competencies,maximal customer orientationanddistributed production. However, in this new productive structure, there are new requirements for planning and for establishing the delivery date of the orders. A conventional Production Planning and Control system (PPC) uses a hierarchical architecture, which does not meet the requirement of autonomy of the partners companies. To address these new requirements, this work introduces a Production Planning and Control System Architecture in EV context. In the proposal are used the concepts oftime windowsandconstraint propagationto meet the deadline requirements of product delivery. These two concepts have been widely used in the literature relating to conventional planning systems, however, not in the EV context. In this approach, thetime windowsdelimit the allocation range of tasks in production systems involved, while the capacity constraint identify the feasible time window considering the importance of the ordes due date. An example of using the architecture and an implementation is presented. This work includes EVs with partner companies of various types of production (production batch and discrete manufacturing). Production Flow Schema (PFS) is used for modeling the processes according to a hierarchical approach based on successive renements to construct progressive and structured model where the properties of model are ensured by construction. This renement generates sub-graphs in Petri Net, which are used for the analysis and control of the production process.

An Ontology for Match-Making in Plug and Play Business Software Platform

Mir, Muhammad Salman khan and Muhammad Arif Raza January 2008 (has links)
An innovation is the process of making improvements by introducing new idea in the form of product or service. In recent years, successful societies are shifting their focus towards the realization and acceptance of these new ideas. Plug and Play business software platform is the first step to transform these ideas into reality. The study presented in this thesis introduced that a new business idea contains specific business role and consists of a set of capabilities or needs and any one of them. Plug and play business software platform mainly consists of three major business processes that are required to run this platform those are; business match making process, negotiating process and collaboration process. This study analyzes the process of business match making in detail and introduce an ontology based business match making process which will find new businesses in a hierarchical fashion based on their specific business roles. Match making ontology consists of three processes i.e. information collection process which is used to collect and register information, extraction process which is an optional process to extract set of capabilities and needs if actor/innovator is unable to define its business capabilities and needs in information collection process and finally finding and ranking process which will find a set of potential collaborators and then will rank that set based on ranking parameters collected in information collection process from actor/innovator. This study also presents a technological model which will provide foundation to develop plug and play business software platform. This model identifies business processes of the platform and presents each business process as a separate loosely coupled software module. This model divides the platform into two layers; the upper layer is called PnP layer and consists of PnP Client Service, PnP Community Service, Finding and Ranking Service, Negotiating Service and Collaboration Service; lower layer is called kernel layer and consists of Security management Service, Operational management Services and Communication Service. Finally partially implemented prototype, test data and results will be used to visualize the presented concept.

No. of bitstreams: 1 Danilo.pdf: 1730178 bytes, checksum: 9368a8c4699b8c6bcbcfdfb44da27ec0 (MD5) Previous issue date: 2008-02-28 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The Virtual Incubator (VI) is one of the newest types of business incubator. They render a great variety of services electronically, by the Internet. The concept of Virtual Organization (VO) is recent and it was introduced by Mowshowitz (1986), as a new organizational model, being composed by a net relatively stable of independent companies, that aim at to participate in business cooperations. The theme "Virtual Organizations" wins relevance as it is researched inside as a strategic alternative to increase the competitiveness and the earnings of a cooperation among organizations (CORRÊA 1999). The objective of the research seeks to define model to allow to create an applicable proposal of virtual incubator with the use of the theoretical reference of the theory of the virtual organizations - Model VIVO. Is that model the answer to the research question on how the theory of the virtual organizations can contribute with the model of incubators, in order to render to the companies and places, appropriate support services to the challenges of the global competitive scenery in the century XXI? The adopted methodology was theoretical-empiric, in the which, besides the revision of the literature on the subject, it tried to verify the coherence with the practical reality, through case study in the market. The study of chosen case is the Park of the Lakes, a project of territorial economical development with several organizations in cooperation, among them two consultancy companies that develop a business alliance together to supply services to the market. The analysis elaborated dimensions and research categories on strategic alliance, characteristics of VO and core competence, in order to produce relevant considerations to the research work on the model VIVO. Some were used instruments of collection of data as bibliographical and documental research, questionnaire and participant observation. At the end, starting from the elaborated theoretical-empiric research and of the case study used as example, it is possible to present the consolidated proposal of the model VIVO, tends like this, a body of solid work to subsidize the final conclusions and the futures studies on the theme / A Incubadora Virtual (IV) é um dos mais novos tipos de incubadora de negócios. Prestam uma grande variedade de serviços eletronicamente, pela Internet. O conceito de Organização Virtual (OV) é recente e foi introduzido por Mowshowitz (1986), como um novo modelo organizacional, sendo composta por uma rede relativamente estável de empresas independentes, que objetivam participar de cooperações de negócio. O tema "Organizações Virtuais" ganha relevância à medida que é pesquisado como uma alternativa estratégica para aumentar a competitividade e os ganhos dentro de uma cooperação entre organizações (CORRÊA, 1999). O objetivo da pesquisa visa definir modelo que permita criar uma proposta aplicável de incubadora virtual com o uso dos referenciais teóricos da teoria das organizações virtuais - Modelo IVOV. Esse modelo é a resposta à pergunta de pesquisa sobre como a teoria das organizações virtuais pode contribuir com o modelo de incubadoras, a fim de prestar às empresas e localidades, serviços de apoio adequados aos desafios do cenário competitivo global no século XXI? A metodologia adotada foi teórico-empírica, na qual, além da revisão da literatura sobre o assunto, procurou-se verificar a coerência com a realidade prática, através de estudo de caso no mercado. O estudo de caso escolhido é o Projeto Parque dos Lagos, um projeto de desenvolvimento econômico territorial com diversas organizações em cooperação, dentre elas duas empresas de consultoria que desenvolvem uma aliança empresarial para fornecer serviços em conjunto ao mercado. A análise elaborou dimensões e categorias de pesquisa sobre aliança estratégica, características de OV e competência essencial, a fim de produzir considerações relevantes ao trabalho de pesquisa sobre o modelo IVOV. Foram utilizados alguns instrumentos de coleta de dados como pesquisa bibliográfica e documental, questionário e observação participante. Ao final, a partir da pesquisa teóricoempírica elaborada e do estudo de caso utilizado como exemplo, é possível apresentar a proposta consolidada do modelo IVOV, tendo assim, um corpo de trabalho consistente para subsidiar as conclusões finais e os futuros estudos sobre o tema

Ein Ordnungsrahmen für Social Networking Services

Richter, Alexander, Söldner, Jens-Hendrik, Bullinger, Angelika, Koch, Michael, Pflaum, Bennet January 2009 (has links)
Der große Erfolg vieler Internet-Plattformen zum Social Networking, wie facebook.com oder myspace.com zieht zunehmend auch die Aufmerksamkeit großer Unternehmen auf sich, die mit ähnlichen Werkzeugen ihr internes Wissens- und Innovationsmanagement verbessern möchten. Im Gegensatz zu anderer Social Software wie Wikis oder Weblogs, die sich in der Regel leicht für den Einsatz innerhalb des Firmen-Intranets adaptieren lassen, ist dies für Social Networking Services (SNS) jedoch schwieriger. Zum einen existieren kaum Open-Source-Anwendungen, die ohne großen Aufwand implementierbar sind. Zum anderen unterscheiden sich die Lösungen von SNS-Anbietern enorm, was es den Unternehmen schwer macht, eine geeignete Lösung auszuwählen. Eine Hilfestellung soll der im vorliegenden Beitrag vorgestellte Ordnungsrahmen für SNS bieten. Entlang von acht Dimensionen ermöglicht er den Vergleich und die Einordnung verschiedener Dienste.
