    • 截至目前BPEL商業流程定義與應用，主要皆針對流程自動化之服務組合與流程設計。對於必須由人員進行互動(human interaction)才能完成的流程活動，在BPEL中並沒有實際的描述。再加上以WSDL作為流程服務介面的描述，並無法提供流程使用者實際流程的執行順序。因此，本論文目標在於設計基於服務遞送(service delivery)之BPEL擴充，讓BPEL具備描述人員活動(people activity)的能力，從而讓人員活動能夠整合入整體商業流程的設計之中，並且讓流程執行順序能實際實現於流程自動化中。除了讓BPEL具備可描述人員活動的的擴充之外，我們在BPEL中也引入服務使用介面(service UI)描述，讓人員在流程進行中能夠透過這些服務使用介面與商業流程進行互動，藉此達成服務遞送的目標。

    In nowadays, the specification and the use of the WS-BPEL mainly focuses on the design of composite services and fully automated process. There is no description about human interaction in the BPEL process. Furthermore, it can not provide process participants the sequence of actual process execution by using WSDL description. Hence, in this thesis we designed two BPEL extensions to implement service delivery, which let WS-BPEL can be able to involve human interactions in process and let people activities be integrated into the design of entire business process. Moreover, we introduced the description of service UI into BPEL, which enables process participants to interact with business process through these service UIs.
