Abstract
Owing to the increasing amount of communication contents in real world, how to cut down the transmission time through web applications has become a vital issue. At the same time, the functionality and reusability of website resources are still of concern. However, traditional framework of Client / Server network is insufficient for achieving the desired performances. Therefore, Distributed Network and Agent-based Network are getting much more attention. To provide a service-oriented platform for meeting different needs and bridging the communications while offering various web services with distributed network architecture will definitely be a significant objective in oncoming development of web technology.n terms of these trends, the thesis proposes an information platform derived from the concept of Service-oriented Architecture (SOA). The information platform follows a real-world condition for people to access. For example, users in an organization can login to this site and use the flow chart or procedures with web services provided. Besides the web services, the thesis also applies the technique of Socket to support the functionality on the platform and to lesson the loadings of web servers for mending the time delays in data transmission. In security issues, login, registry, and cookies mechanisms are entirely encrypted. The administrator of this platform can easily view users’ status and login time by the constructed GMPP web service so as to do web management. Additionally, this platform also offers users of Event-Recorder to record all acts done on the web site, and the stored data could be checked lately when needed.n addition to those web services, the thesis constructs a web-based factorial simulation system of photolithography area in semiconductor fabrication as well. Through the application, one can get the dispatching results and performance indexes including average cycle time and throughput. There is also an auxiliary functionality as scheduler selector, which seeks for the best schedulers by putting Neural Network, Support Vector Machine (SVM), and Fuzzy Logic in use. inally, after the simulation procedure, the Principal Component Analysis (PCA) based Statistical Process Control (SPC) method would be used to find the most contributing factors and do the statistical diagnosis. The managers of the factories would then be able to keep in pace with the conditions within fabrication and manufacturing processes.
