碩士 === 國立中正大學 === 通訊資訊數位學習碩士在職專班 === 105 === Root-cause analysis (RCA) is a process to identify the exact reason of the problems. Many RCA methods have been proposed in the literature, and they are very helpful to help administrators better understand what to look for and how to solve the problem. In this thesis, we use the music box test, a National Skill Examination in Taiwan, as our case study of RCA, which first converts the system into an initial dependency graph and applies divide and conquer algorithm to recognize the root cause. From the initial study analysis, our RCA has a better performance than the solution using if-then-else statements inside a conventional RCA process.
