Quality Function Deployment — QFD combined with Concurrent Engineering — CE as a support tool for the competitive strategy on product development is devised. In this study, beyond the proposed method, it is intended to develop relations with innovational models, arrangements of innovation and technology transfer, learning in organizations, and how the diffusion of knowledge occurs. QFD can also be one those main tools of CE as this identifies the customer’s main requirements translating into the features required for products. The field survey of exploratory and descriptive type, using the questionnaire as data collection technique, was carried out in the manufacturing companies in the fast growing sectors of automobile industries in the State of Parana located in the Southern of Brazil. The selection of sample companies was made intentionally to guarantee of return of answer through the accessibility criteria. The reasons for this fact that can be pointed out are: the use of “home made” methodology to fulfill customer’s requirements, unknowing of the methodology, and the lack of adequate training to use QFD. It is expected that the results of findings, if disseminated adequately among local companies, will help to enhance the competitiveness performance beyond the local market scenario.

In industry segments such as automotive and industrial equipment the use of compressed porous materials is well known to improve the global acoustic performance of the complete system. Such porous materials should be designed in a specific way in order to reach a significant acoustic sealing performance at different compression rates. Unfortunately, there are no standard measurement procedures nor predefined material characteristics that allow the selection of the right material with the optimal acoustic performance. The main goal of this research is to link acoustic performance of compressed porous materials with intrinsic material characteristics using statistical techniques.

This paper outlines a framework for applying a genetic algorithm to the selection of component variants between the conceptual and detailed design stages of product development. A genetic algorithm (GA) is defined for the problem and an example is presented that demonstrates its application and usefulness. Functional modeling techniques are used to formulate the design problem and generate the chromosomes that are evaluated with the algorithm. In the presented example, suitable GA parameters and the break-even point where the GA surpassed an enumerated search of the same solution space were found. Recommend uses of the GA along with limitations of the method and future work are presented as well.

Employees of an agricultural research unit were evaluated for selection as rum tasters. Prospects were classified and ranked considering their relative consistency in four organoleptic tests of four rum samples and their evaluation relative to those of an experienced rum taster. Statistical techniques used were variance analysis of Latin squares for the scores of the evaluation of 10 rum attributes and the calculation of a rum evaluation index for each taster using a linear discriminant function.

Aufbauend auf einer zeitlichen und inhaltlichen Abgrenzung im Produktentstehungsprozess (PEP) stellt der Fachbeitrag verschiedene Probleme vor, die bei der Serienreifmachung allgemein und in der Nutzfahrzeug-Industrie im Speziellen auftreten. Anschließend werden Herausforderungen abgeleitet, die es bei der Entwicklung eines Konzepts für die Serienreifmachung in der Nutzfahrzeug-Industrie zu bewältigen gilt.   Based on a definition of the process of attaining production-readiness in the context of the product development process, this article presents several problems that occur during the process of attaining production-readiness in general and specifically in the commercial vehicle industry. Furthermore, a selection of challenges is derived from the presented problems and an approach to cope with these challenges is suggested.

AbstractPrototyping is an essential activity in product development, but novice designers lack awareness and purpose when they prototype. To foster prototyping mindsets in novice designers, we introduce a prototyping support tool that structures prototyping activities. This paper outlines the Prototyping Planner's development, evolution, and evaluation by 125 novice designers. The majority of novice designers’ experienced that the Prototyping Planner helped them create purposeful prototypes and evaluate results from prototyping.
