Dependency Structure Matrix

A four-stage methodological framework useful to analyze the performance of a product development process, with a focus on the information flow inefficiencies is presented. The formal and informal communication exchange between interacting tasks is captured through the Dependency Structure Matrix (DSM) representation, while the properties of the information flow structure are explored calculating metrics of Social Network Analysis (SNA). Information exchange inefficiency of process tasks is calculated performing Data Envelopment Analysis (DEA).

Copula Approach

Data envelopment analysis (DEA) is a method that finds the effectiveness of an existing system using a number of input and output variables. In this study, we obtained energy efficiencies of construction, industrial, power, and transportation sectors in OECD countries for 2011 using DEA. It is possible to achieve the efficiencies in different sectors. However, we aim to find joint energy efficiency scores for all sectors. One of the methods proposed in the literature to obtain joint efficiency is network data envelopment analysis (network DEA). Network DEA treats sectors as sub-processes and obtains system and process efficiencies through optimal weights. Alternatively, we used a novel copula-based approach to achieve common efficiency scores. In this approach, it is possible to demonstrate the dependency structure between the efficiency scores of similar qualities obtained with DEA by copula families. New efficiency scores are obtained with the help of joint probability distribution. Then, we obtained joint efficiency scores through the copula approach using these efficiency scores. Finally, we obtained the joint efficiency scores of the same sectors through network DEA. As a result, we compared network DEA with the copula approach and interpreted the efficiencies of each energy sector and joint efficiencies.

Sheet Metal Parts

Within the Collaborative Research Center 666 the algorithm based product development process has been established. It is based on state of the art product development methodologies and enhanced in order to optimize the product development process of integral bifurcated sheet metal parts. Algorithms based on mathematical optimization approaches as well as the initial product requirements and constraints information are applied to obtain an optimized design as CAD-Model. Regarding this methodology there are still some challenges to be solved, such as reduction of iterations steps to elaborate final product design as CAD-model, use of heterogeneous data as well as software and enhancement of information exchange. Therefore, this paper introduces a concept for a web-based application to support the algorithmic product development methodology and CAD modeling in CRC 666. It enables the development and adaptation of integral bifurcated parts based on the initial optimization data provided by XML-files. Besides the description of use cases and use scenarios, the concept is implemented as a web-based application for validation purposes. Based on the validation, advantages and limitations of the presented approach are discussed.

AbstractProduct customization aims to consider individual customers preferences in the design of new products, in order to directly involve them in the product development process and to maximize their satisfaction. It can be considered a key competitive factor and a “hot topic” in several industrial sectors, including luxury apparel goods and high-end footwear products. However, currently the design and manufacturing of customized shoes are carried out through artisanal and non-standardized processes, based on the individual expertise of operators.The objective of this study is to define an innovative framework to support the different processes affected by customization. This framework is enabled by different digital technologies, as CAD-based tools, virtual/augmented reality systems, etc., opportunely integrated in the product development process. The main benefits related to the framework implementation in real industrial contexts are an increase of flexibility, the repeatability of processes, a higher efficiency in information exchange, a more effective involvement of final customers, and, as a consequence, the reduction of time to market and production costs for tailor-made shoes.

O objetivo deste estudo é analisar as características das publicações internacionais na temática avaliação do desempenho hospitalar (ADH), por meio de um fragmento da literatura, na busca de geração de conhecimento, identificação de lacunas e possibilidade de contribuições. Esta pesquisa utiliza uma abordagem qualitativa e o instrumento selecionado para identificar e selecionar o fragmento de literatura para análise e reflexão foi o Knowledge Development Process – Constructivist (ProKnow-C). O portfólio bibliográfico com 43 artigos identificou os autores e os núcleos de pesquisas de destaque e os periódicos com maior número de publicações. Quanto aos métodos mais utilizados na ADH, destacam-se os que se baseiam na teoria das fronteiras Eficientes, classificados como: Data Envelopment Analysis (DEA - 53,85%), Stochastic Frontier Analysis (SFA - 12,82%), comparação entre DEA e SFA (7,69%) e Partinal Frontier Analysis (2,56%). Quanto ao emprego ou dimensões analisadas, 38,46% dos artigos destinam-se aos gestores. A partir das análises geradas foi possível identificar lacunas, referentes a mecanismos de avaliação do desempenho voltados para as dimensões que extrapolem as métricas. Para geração e aplicação de conhecimento nesta área, sugere-se a adequação da ADH as especificidades destas organizações, considerando o ambiente e a finalidade do sistema ao qual se insere.
