碩士 === 佛光大學 === 管理學系 === 100 === Since ECFA has taken effect and many developing countries have witnessed economic growth, Taiwan’s industries have met with an increasing number of competitors. These competitors have lured customers away from their Taiwanese counterparts by adopting the low price strategy, which poses a great threat to Taiwan enterprises. For many years, diving suits produced by Taiwan had the largest global market share. However, the gradual reduction of orders placed by customers in recent years has brought about overwhelming challenges and threats. As a result, Taiwan’s diving suit manufacturers must promote product quality and technological innovation in order to overtake their competitors and maintain the competitive advantage in the market, thus setting the quality benchmark in the industry. This research is intended to construct an integrated Quality Function Deployment (QFD) model for improving quality of diving suits by avoiding failures of potential products. First, the Failure Modes and Effects Analysis (FMEA) is employed to reveal the voice of customers (customers placing orders) for the purpose of grasping the failures between customer needs of diving suits and manufacturing process. Moreover, the 39 engineering parameters of the Theory of Inventive Problem Solving (TRIZ) serve as the technical requirements for improving the quality of diving suits. Next, FMEA and TRIZ are integrated to construct the QFD model for finding the relationship matrix of diving suits. Finally, the technical requirements of higher importance are identified by way of House of Quality (HOQ) matrix which is followed by the application of QC 7 Tools to obtain the action plans for quality improvement. This will help promote the quality of diving suits. According to the empirical results obtained from the case study, the top three failure modes with the highest RPN scores obtained from FMEA are break and hole in cloth cap piece, weak bond, and lack of flexibility which are arranged according to their scores from high to low. Through the expert questionnaires of the relationship matrix of HOQ, the three most important degrees of the TRIZ engineering parameters after calculation in order are: speed, force, and stability of subsystem. This results show the priority direction for technical requirements for improving quality of diving suits. Finally, this study utilizes the Cause &; Effect Diagram to analyze detailed improvement plans, and applies the Pareto Diagram and the Control Chart to control elements of manufacturing process to reduce the failures of diving suits. The framework of this research can serve as the reference model of continuous improvement for traditional industries, enabling enterprises to enjoy sustainable development and create perpetual success via systemized management. In addition, the empirical results can improve the yield rate of diving suits to enhance their competitiveness in the market.
