| Summary: | 碩士 === 中原大學 === 工業與系統工程研究所 === 99 === In order to be competitive in the global market, enterprises have to quickly response to customers’ demands, and they must constantly update product types to satisfy customers’ needs. However, the collaborative design process of new product may change frequently, due to customers’ demands or market variations, and this situation makes the product design management very difficult. This research proposed to apply service oriented architecture (SOA) as the framework for the information system of the product design workflow.
SOA emphasizes on integrating distributed Web Services in a loosely coupled way, and the key step of developing a SOA system is service identification. This study proposed a hierarchical workflow model to increase system flexibility and services reusability. The workflow model is consisted of functional process, sub-process and activity from top to bottom. Then, a service identification method was developed to find services based on workflow requirement. In order to increase services reusability, this study proposed that services should be designed based on workflow activities; therefore, the same services could be applied in different workflows in which activities are similar. In such a case, services reusability is improved and service building cost is reduced.
This research implemented a workflow information system based on SOA, and this architecture correlated with the hierarchical workflow model. The WebSphere Integration Developer (WID) from IBM was applied to build the new product design process, and system flexibility was tested by an example. The results show the proposed service identification method increases service reusability and the developed information system can be easily modified in various situations.
