本論文主要在探討正式模型正確性的需求,我們稱這個模型為個人化流程,個人化流程是將個人的活動加以協調,流程中的每個活動需要確保使用者和組織間連結的關係,我們確認出資料和暫時性相依的關係為協調個人化流程的重要元素,我們針對個人化流程的類型和實例定義其正確性,我們還對個人化流程的實例確認出三個服務品質的指標,分別是時間、花費和可靠度,而我們是透過個人化工作流程管理系統來管理個人化流程,個人化工作流程管理系統是在手持式裝置上面執行的系統,因為考慮到手持式裝置計算能力和電力的限制,我們因此提出了有效率的演算法來確認和分析服務品質的指標在個人化工作流程執行階段的正確性。
This thesis addresses the correctness requirements of a formal model. This model is called the personal process model. A personal process is a coordination of personal activities, each requiring a joint effort between a user and an enacting organization. We identify data and temporal dependencies as the key elements for personal process coordination. We define the correctness on personal process types and instances. We also identify three key QoS measures on personal process instances, namely the response time, the cost and the reliability. A personal process is managed by a personal workflow management system (PWFMS) running on a handheld device. Considering the fact that handheld devices usually impose strict limitations on their computation power and battery consumptions, we propose efficient algorithms for verifying the correctness and analyzing the QoSs of a personal process at run-time.
