Integration and Application of Web-Service-Based Expert System and Computer Maintenance Management Information System

The information technology has experienced breakthroughs in recent years. Enterprises have begun to introduce information systems to help with business operations. Constantly or even perennially in use, high-tech computer equipments are showing hardware abnormalities or malfunctions on a regular basis. In view of the issue, this study utilizes a multifunctional integrative expert system to help maintenance staffs diagnose and remove computer system problems with the attention focused on hardware trouble removal. Traditional expert systems, however, are under development and integration constraints, such as the fact that its development is more time-consuming, that it cannot be used repeatedly and that cross-platform application is difficult. This study therefore attempts to employ the concept of service-oriented architecture (SOA) and establish two heterogeneous Web services components including the computer maintenance expert system and the maintenance management information system. It also incorporates the application of wireless LAN (WLAN) in one system in order to demonstrate the integration and application of the expert system and WLAN in Web services environment.
