碩士 === 國防大學中正理工學院 === 電子工程研究所 === 93 === Promoting service qualities and reducing manpower costs by monitoring, controlling, and identifying products and equipment through networks are important topics for current enterprises. Especially, the military whole logistics demands the properties of timeliness, convenience, and stability. However, the current operations of logistic supply usually possess the problems of uncertainty in inventory, ignorance of the material locations, and not being able to timely provide proper qualities of spare parts for maintenance. To improve these shortcomings, this thesis proposes a novel Web-based monitoring and control system by using technologies of Radio Frequency Identification (RFID), Middleware, and Web Services. First, the system utilizes RFID tags to store the data of products and uses various kinds of readers to automatically acquire product information for increasing the efficiency of inventorying stocks. Next, we design a RFID middleware that contains reader interfaces, data processing modules, and application interfaces such that the readers and external application systems can mutually communicate and exchange information. In addition, this research constructs a material-flow platform that can real-time trace transported materials and products. We also adopt the linear regression to predict the demand of spare parts. Based on historical consumption data, the system can dynamically estimate the “zero date” and “purchase date” to facilitate the purchase organization to properly plan the operation time. Finally, we deploy and test the developed Web-based monitoring and control system according to the military three-tier logistic maintenance architecture: Organization, Intermediate, and Depot. The results of integration tests show that the proposed system can effectively improve the deficiency of current military logistic supply operations. The associated research results can also be useful references for constructing future military whole logistics policies.
