| Summary: | 碩士 === 國立交通大學 === 工業工程與管理系所 === 95 === Liquefied Petroleum Gas (LPG) is an important energy source for many homes, restaurants, and industrial sites in Taiwan. Also, how to transport various kinds of bottled LPG in a secure way have inevitably generated many public safety issues. One of them is to inspect the quality of each LPG steel bottle regularly; thereafter an aluminum-based license plate with a valid period is attached to each qualified steel bottle. Another important one is to build a traceability system for monitoring their movements and locating the positions of LPG steel bottles before the expiration of their licenses. In this thesis, a distributed information system based on web service technology is proposed to solve the steel bottle traceability problem. The research includes the analysis of LPG steel bottle supply chain in Taiwan, the design of tracing codes for steel bottles, and the analysis of information flows. More importantly, a web service based prototype traceability system has been implemented. Also this implementation shows the feasibility of web service approach for solving the tracing bottled LPG problem.
