本研究發展的案例式推理系統，案例以類型抽象階層來表達，並以鄰近值集合產生適當的SQL表達式，以完成關聯式資料庫的相似度為基礎的擷取，利用資料採礦當中的關聯規則分析方法找出修正新案例的規則。修改後的案例用以支援以個案處理為基之工作流程當中的表單系統，工作流程一開始是以案例式推理系統的新案例的特徵屬性值輸入，根據新案例的特徵（屬性─值）擷取出案例庫中，一個或多個與新案例相似的案例，經由相似案例的再使用和修改過後，得到新案例的解決方案，並且產生個案處理為基之工作流程當中的新的個案實例，進行後續的流程活動。
旅行社的客製化服務（量身訂做或企業專區）普遍都是讓使用者輸入相當概略的需求，例如：旅遊地點（國家、城市）、日期、人數、預算，或是讓使用者留下聯絡資料。因此本研究發展的方法可應用在此類旅遊服務，以案例式推理系統實現旅遊活動的建議方案機制，同時能夠配合個案處理為基之工作流程表單，在產生建議方案後，由建議方案的資料控制決定後續的活動。讓使用者依需求產生的建議方案決定旅遊活動後報名，以及處理因不同旅遊活動產生不同的活動，以及其他需求的表單。

This thesis develops a case-based reasoning (CBR) system to support workflow. Cases in the CBR system are presented by abstraction hierarchy. When a new case input into the system, the abstraction hierarchy can conclude neighbor value sets to generate SQL (Standard Query Language) expressions are used to retrieve similar cases from case library. Furthermore, abstraction hierarchy calculates similarities between the new case and similar cases. The association rule analysis is used to find rules for case adaption.
The workflow start when new case with feature attributes values input into. According to the features (attribute-value) of the new case, one or more similar case(s) are retrieved. Solution of new case is generated by reusing and revising solution(s) of similar case(s). The new case with revised solution become a new workflow instance, and continues to execute activities.
Most travel customizer services are provided to user to input simple requirement or just only input user’s contact information. This research could apply to the kind of travel services. Travel activities solution suggesting is realized by CBR system. The solution would affect subsequent activities and forms. Users may obtain solution based on their requirement. The workflow would handle different activities and forms result from different travel activities solutions.
