APPLICATION OF QUALITY FUNCTION DEPLOYMENT METHOD AND FUZZY LOGIC FOR IMPROVING THE DESIGN CHARACTERISTICS IN FRP COOLING TOWER-CASE STUDY

摘要

Quality Function Deployment is a continuous improvement technique applied in the design of an FRP cooling tower.QFD helps to develop customer oriented, higher quality products. In order to improve the quality characteristics of this product and to satisfy the customers, the technique such as QFD followed by fuzzy logic technique approach is done. Though, the QFD method has some draw backs, it is one of the most important methods to interpret customer needs for specific quality development. To overcome this drawback, fuzzy linguistics approach is proposed in this paper. This paper shows how QFD approach can be combined with fuzzy logic to resolve some of its drawback. Finally, these two approaches have been compared to know which applies the best for this case study.
