Abstract
Failure mode and effects analysis (FMEA) and fault tree analysis (FTA) are widely used to analyze the aviation safety, chemical process, and servicing products because of their broad applicability and detailed outcomes. However, when facing a rapidly evolving industry and spontaneous changes in manufacturing processes, the analysis team often requires setting a specific event for analyzing target, and thus becomes a very time-consuming task if using these two methods in a the traditional combining way. In addition, when the target system is huge and complex, it will become inefficient and could result in possible data lost without the assistance of computer software. Therefore, this study attempts to solve the problems by revising the combination steps of FMEA and FTA as well as the computer software aiding. To achieve the research objectives, the qualitative and quantitative analyses of FTA were performed respectively to find out the most critical components. Then, analysis of FMEA on the current detection methods, alert design, and reaction of each failure mode of critical components were conducted to provide recommendations to improve the safety design and management. Furthermore, an efficient computer software has been used to assist the running of analysis and data interconnection. This study took a solar cell plant in Taiwan as a case and analyzed the safety design and management of two systems which related with a hazardous chemical, Diethylzinc. The result showed the weakness in two systems and safety suggestions presented.
