Web-based design review portal with fuzzy set theoretic methods for fuel pump designs
ABSTRACT Design review is used throughout the product development process to evaluate the design in terms of costs, quality and delivery, to ensure that the most suitable knowledge and technology are incorporated into the design, and to resolve possible problems instead of passing them downstream. Business globalization has extended design review activities to involve interdisciplinary members within and outside the enterprise, either geographically collocated or dispersed. This paper first proposes a systematic and rigorous framework based on a Systematic Theory of Axiomatic Design Review for more efficient and effective design review. The resulting framework is adequately well-structured and generic, enabling it to become the basis for developing a web-based design review portal in the extended enterprise. The framework is extended further to formulate a new design review technique called FuzzySTAR (Fuzzy Set Theory Approach to design Review). This paper demonstrates how design review tools are accommodated within the design review enterprise portal and how to use FuzzySTAR for reviewing the design of a fuel pump.

ABSTRACT: This paper describes a web-based design review system as a knowledge management system relating reliability and safety system design. Since people's consciousness for safety and security become sensitive and increases the need of establishing a proactive prevention method for internal failures and relating risks in products. It also means that prevailing tacit knowledge in retired workers, in order to transform them to be easily used to support new system development, become more important. When considering safety and reliability design, at least two data sheet are necessary; Failure Modes and Effects Analyses (FMEA) and Risk Assessment (RA). These two data are practically made separately. However, it includes the concerns that a risk by failures during long-term use may not be noticed. To overcome this insufficiency, a support tool for integrating reliability evaluation and risk assessment data simultaneously is expected to be revealed. The authors have then developed a web-based design review system for reliability and safety system design. The system include various profitable functions; making FMEA and RA sheet, retrieving past data sheet for engineering change management and new product development and web-based discussion to increase the efficiency of discussion. The system is applied to one practical development works in order to demonstrate its effectiveness that is to be made clear by interviewing user's qualitative comment.01/2010; 9(2).
