Integration of computer simulation in design for manufacturing and assembly

As a reason for competitiveness, the process of product development evolves using, in some situations, improvement methods, e.g. design for manufacturing and assembly (DFMA). In the framework of the product development process, it is desirable that engineers and managers have a systemic view of the effects that changes in local processes will have on the overall performance of the entire production system. This vision of such effects can be achieved with computer simulation. This study aims at assessing how DFMA can be integrated with computer simulation and the benefits from the alternatives identified by such method during production and assembly. Using the electronic voting machine printer as object of study, options to improve design by means of DFMA principles are identified. Five models were developed to represent the current assembly process and two models following the implementation of the changes proposed by the DFMA. The sale price is confidential (exclusive product of the Brazilian government). The company provided data in assembly costs. The results show the production increase in assembly time (9.94%) and average daily sales (

A Reference Model for the New Product Development in Medium-Sized Technology-Based Electronics Enterprises

O gerenciamento do Earned Value vem obtendo aceitacao crescente nas empresas e entre profissionais tais como gerentes de projetos e funcionais, devido a sua efetividade no controle dos resultados do projeto. Earned Value e definido como uma ferramenta de controle que permite avaliar simultaneamente de maneira quantitativa como se encontram os custos e prazos em uma data de controle, permitindo tambem prever a data de termino e o valor gasto (VARGAS, 2005). Este artigo avalia a aplicabilidade do earned value como ferramenta de controle de projetos aeronauticos na EMBRAER. Contribui tambem para a aplicacao do earned value no controle de projetos complexos. Utilizam-se como tecnicas de coleta de dados: entrevistas, observacoes e analise documental. Conclui-se que o earned value e utilizado apenas nos projetos da area de aviacao de defesa, por ser uma exigencia contratual. O uso do earned value nas areas de programas executivos e comerciais restringe-se as fases de definicao conjunta, projeto detalhado e certificacao, pois o escopo do projeto e bem definido, o cronograma e detalhado e os custos sao previstos e obtidos com maior acuidade. Nas demais fases de desenvolvimento do produto, o uso do earned value e restrito, devido principalmente as constantes alteracoes de escopo do produto e do projeto.Earned value management has been increasingly used by companies as well as by functional and project managers due to its effectiveness in controlling project results. It is defined as a control tool that enables a quantitative and simultaneous evaluation of the costs and process time within a pre-scheduled date as well as predicting the deadline and the total value spent (VARGAS, 2005).This study evaluates the earned value applicability as a tool to control aeronautical projects at EMBRAER, A Brazilian Aeronautical Company. It is also concerned with the application of earned value in the control of complex projects. The data were gathered through interviews, observations and document analysis. The results show that The Earned Value is used only in the defense aviation projects since it is a contractual obligation. Its use in executive and commercial areas is restricted to the combined definition stages, detailed project, and certification because the scope of the project is well defined, the schedule is detailed, and the costs are foreseen and fairly accurate. In the other stages of the product development, the use of earned value is restricted mainly because of the frequent changes of the scope of the product and project.

Identificação dos fatores críticos de sucesso no desenvolvimento de produtos de empresas de biotecnologia do estado de Minas Gerais

New Product development (NPD) is getting even more significant to the entrepreneurship competitiveness due to the increasing market internationalization, to the product diversity and variety and the reduction of the product life cycle. This present work has as its main goal to propose a reference model adapted to NPD of technology-based companies (TBC) that produce electronics. This research follows a combined methodology approach, that is, a qualitative-quantitative approach. First, a qualitative approach is applied with the study of multiple cases in order to identify the NPD features based on electronics manufacturing. Then, a qualitative approach is employed with application on multi-criterion decision-making method as to select macro-phases, phases and activities from the proposed model for NPD. Finally, studies of multiple cases are carried out to verify the proposed model adequacy. The results analyses suggests that the proposed model may be considered convenient.

Impacto das funções desempenhadas pelos gerentes nos resultados da incubadora: survey realizada na rede mineira de inovação

Abstract This research analyzes the incorporation of risk management in the product development process (PDP) in auto parts companies, based on Advanced Product and Quality Planning (APQP), and emphasizes the delivery of project development proposed by the Production Part Approval Process (PPAP) and conducts a review of the literature, establishing the theoretical foundations for its development. The research method used was action research, where data were collected through documentary analysis, interviews and researchers’ observations. The incorporation of risk management contributes to the PDP‑making processes, especially in the stages of qualitative risk analysis and planning of responses to risk, providing greater accuracy of the time and identification of critical activities. The factors that emerged as most important for guaranteeing the accuracy of the results are: team building; collective discussion of deadlines set, resulting in commitment; the role of project manager, providing feedback from the participants; the existence of objective evidence in support of senior management. It follows that team‑building impacts on risk management, as in the perceived risk to ongoing education.
