一工作流程管理系統中代理機制之分析

Abstract

除了之前許多在工作流程系統特點上的研究之外，有些問題尚未被發覺。其中的一個就是代理機制。代理機制可以讓工作流程經由代理而能繼續運行。本篇論文呈現的是在工作流程系統中代理機制之分析。其中呈現的有兩個會發生代理的不同劇本以及數個代理規則的討論，進而呈現了代理機制的細節。之後代理機制中依據不同的代理規則會發生的問題將會被討論。而為了要找出這些問題，將會提出一個方法，而這個方法能將代理規則跟代理的關係以圖形化的方式呈現出來。根據這個轉換的圖形，相對於這些問題的演算法將會被提出來讓找出這些問題更加容易。

Despite many research works in the features of Workflow Management System (WFMS), several issues are not researched yet. One of them is the delegation mechanism. Delegation mechanism ensures the continuity of processes. This thesis presents an analysis of delegation mechanism in a Workflow Management System. Two scenarios in which delegations happen and several delegation rules are shown as the detail of delegation mechanism. Then several problems of delegation are discussed based on the delegations and delegation rules. In order to find out the problems with delegation mechanism, a method is discussed to transform the delegations with delegation rules into a graphic view. With the graphic method, algorithms of finding corresponding delegation problems are presented.
