| Summary: | 碩士 === 中原大學 === 工業與系統工程研究所 === 104 === The technical capabilities of aerospace industry represent the industrial level of a country. The attributes of that has the uniqueness of technological professionalism, domination, concentration, and system integration. The aerospace industry has the features of high supply chain relevancy, great potential market, strict quality demand and low pollution. Quality and Safety are the main concern in the aerospace industry. The foundation of safety and quality control is to comply with aviation regulations and technical standards.
This study starts to use the FMEA method to figure out the failure modes from the production process. By applying the results, RPNs are determined. The risk factors are sorted and classified through failure modes and RPNs from the largest value to the smallest value. On the other hand, IDEF0 is constructed to realize the present system. The potential failures by FMEA are the inputs for the improved IDEF0 to promote the production process efficiency and productivity. Finally, this study suggests modifications of the present system with the improved IDEF0 and analyzes the benefits after the improvement to validate the solution approach by this study.
The contributions of this research are as follows. The study combines with FMEA and IDEF0 to analyzes and modifies the aviation product production process including incoming inspection, testing and appearance check, and out-going inspection from the example company and obtain the significant improvement. Thus, this study is proved to have the following effect which can be standardized as the operation procedure.
(1)Operational clarification: To analyze the example company incoming inspection, testing and appearance check, out-going inspection via IDEF0 method can make operators much more familiar with their operational procedure.
(2)Decrease the failure rate: The modify processes including incoming inspection, testing and appearance check, out-going inspection can reduce the failure rate result from operators who do not comply with operation standard.
(3)To reduce customer complaints: The modify production process will not only reduce the failure rate but also prevent defective product occurrence from the customer’s end. Hence, this can efficiently reduce the number of customer complaints about quality concerns.
The improvement method of this study can serve as a reference for Aerospace Industry or other technology industry in attempt to effectively optimize the production process.
