Abstract:	本篇論文我們提出一個決策支援系統架構，去協助採用資料採礦模型於實際應用中。透過該決策支援系統，可以整合具有該領域業務知識的專家與具有資料採礦知識的專家，以達到採用資料採礦模型去協助應用案例的最佳方法。在一開始的訓練階段，會建構包含行銷設計、產品資訊、資料採礦模型與成效評估相關的知識於知識庫中。推論引擎會負責整合業務專家與資料採礦專家的協助去完成建模相關的工作，並將模型存放在知識庫中。這些模型可以在反覆採用模型的流程中，根據衡量商業目標的達成率與累積每次的應用結果，回饋知識庫以進行模型精鍊。我們設計三個評估測量達成目標的測量標準，以協助評估採用資料採礦模型於實際應用的執行成效，並透過這三個評估測量結果成為一個回饋機制給知識庫去調整行銷方案或者試模型。這整個決策支援系統架構，可以儲存採用模型於實際應用時的每一個相關參數，包含建模流程、行銷應用流程及回饋機制等，這些參數可以協助累積執行經驗於知識庫中。我們也設計一個處理電信業的客戶流失問題的實驗架構去評估我們所提架構的效能與可行性。流失客戶管理是客戶關係管理系統中很重要的一個議題，也是一個典型採用資料採礦技術的應用。可是，以往較少將採礦技術與行銷同時討論，但不僅試資料採礦模型本身，後面的挽留活動配合也都是影響流失管理成效重要的因素。我們所提出的實驗架構也可做為採用資料採礦於新應用的前導專案流程，經由我們所提出的三個達成目標的測量標準:修改測量標準、執行成效測量標準及成本效益測量標準，在每次執行後，了解需對模型或行銷方案如何進行修改，協助逐步優化採用模型成效。我們也採用這個決策支援系統架構在入侵偵測應用。其所建立的三個警示分類的規則可以協助專家快速的發掘可疑的模式或快速準確的發掘進行入侵的模式，也可明顯的減輕專家於線上警示分析系統的負擔。後續，我們將持續專注在如何整合更多業務知識、商業角度參數與資料採礦模型的相關知識至系統中去協助解決客戶關係管理中各項商業應用的重要議題。 In this dissertation, we proposed a novel decision support system framework to help for adopting data mining models easily in real world applications. Through the decision support system, domain experts can help provide the business related knowledge and the data mining experts can help provide the technique related knowledge. In training stage, the knowledge base are firstly constructed which consist of marketing plan, promotion plan, data mining models, and some model evaluation related knowledge, etc. The Inference Engine are responsible to construct data mining models via data mining experts and domain experts’ assistances stored in knowledge base. Those models can be refined according to the considerations of profits and different business goal in several iterative cycles. We also design three good effectiveness measures to aid in evaluating the execution effectiveness and give a proper feedback according to the knowledge base to adjust data mining models or redesign marketing activities. The DSS framework can store the relative parameters of each adoption of data mining models in knowledge base can help for accumulating execution experiments. To evaluate the effectiveness of our proposed models, we designed an experimental architecture on telecom churn management application. Churn management is a critical issue of customer relationship management (CRM). Not only the data mining models but also the retention activities influence the results of the churn management. The proposed experimental architecture based up our decision support system framework can take as a design of a pilot project for real application. Three measures including modification measure, execution effectiveness measure, and cost benefits analysis are proposed to aid in adjusting the data mining models. For those models which need be adjusted, we can know how to improve the result of decreasing churn rate by adjustment of data mining models or marketing activity according to the effectiveness measures. We also adapt the decision support system framework on network intrusion detection application, we construct three kinds of alert classification rule classes to help experts quickly discover suspicious or intrusion patterns quickly and precisely, and lightens the load of on-line alert analysis system for experts obviously. In the future, we will focus integrating more domain knowledge, business considerations, and mining models into this system and solve the critical problems is customer relationship management in real business applications.
