A Methodology For Failure Data Collection And Failure Rate Computation For The Petro-Chemical Industry In Taiwan

[[abstract]]近年來設備管理與維修保養體系的角色，不再只是被動的故障排除，已轉向與風險管理技術結合，並追求效益、成本、與最佳化。在設備管理作業中，不論是保養週期的推估，還是於失誤樹與風險之計算，設備/元件失效率數據的使用都是不可或缺的，但目前所使用之設備失效率數據均源自國外機構所出版之資料庫。設備失效率與行業別及所在地極為相關，如欲用於國內，則應用本土之資料庫。 本發明特別考量我國石化產業特性，以最新的設備編碼架構進行失效率資料庫的規劃，同時考量以網際網路的平台為設計程式。原始數據為以來自石化產業設備的故障資訊與維修記錄，利用ISO14224標準，進行設備分類、時間的編碼、失效模式歸類等。程式環境為PHP和MySQL的搭配，旨在建立網頁化的失效率處理與數據檢索系統。[[abstract]]In recent years, roles of equipment management and maintenance in a plant had gone from resolving breakdowns to adopting performance-oriented, and cost-conscious approaches, which often involve risk and reliability related techniques. Equipment/parts failure rate data is deemed essential in all kinds of tasks in plant asset management, including determination of inspection intervals and calculation of risks. In Taiwan, systematic collection and therefore utilization of the failure rate in an organization is extremely rare except in the aerospace industries and military facilities. As for other industries, it is unlikely for an individual companies to maintain a proprietary database. It is an aim of this research to develop an failure rate database as well as a data handling and searching program for the chemical industry, in which raw equipment maintenance records are from various companies. The program is designed with PHP as the front end developing language and MySQL as the database management tool. In order for easier access, the program is designed be web-based
