以社會網絡為基礎之案例式推論群體決策模式

群體決策藉由群眾參與、討論、與協調解決問題，並且透過一些規則，讓決策過程具有效率和結果具有一致性。本研究以啟發式概念為基礎，提出以社會網絡基礎之德菲法群體決策模式，並且結合案例式推論方法，設計一套群體決策模式來探討於E化服務環境中，集合專家意見並且協調與整合進一步解決使用者問題，並且建構出使用者的社會網絡體系來蒐集所需資料，讓使用者能以互信為前提，相信並且接受系統意見，間接讓企業之產品或服務的推廣程度提高。本研究目的主要有: (1)改良傳統德菲法的決策模式應用至E化環境；(2)結合案例式推論法建構具創新之社會網絡群體決策模式；(3)藉由社會網絡成員經驗，提高使用者接受群體決策意見的程度；(4) 以專家經驗增加案例式推論資料庫的概念來解決使用者一般性問題。因此，本研究蒐集三位使用者的社會網絡背景和經驗，實際建構使用者社會網絡結構，進行決策過程及分析驗證。主要貢獻在於提出一種創新決策模式於E化服務中，並且結合傳統理論和技術，快速讓使用者能獲得所需資訊之時，也間接地讓企業產品曝光度提高。

Group decision making approach provides an effective process by discussing, arguing and coordinating the coalition among participants that reaches a consensus through some rules. This research aims to design a group decision model based on traditional Delphi Method, utilize and construct a user’s social network, and deploy case-based reasoning approach to solve the problems. The proposed group decision model collects knowledge and experiences from peers of their social network, and attempts to conduct a group decision making process. This work assumes the users trust their friends, relations, and etc. and may accept the final solution(s). This study have four research purposes: (1) refining the traditional Delphi decision model and apply to an Internet-based environment, (2) combining case-based reasoning approach with the concept of social network, (3) improving the acceptance of users for the outcomes that are generated by peers from the social network, and (4) solving the problem by expertise which may enhance the accuracy of CBR. Hence, this study collects the data of three different users including their social networks, examines the performance of our model, and proves the feasibility and validity. The major contribution is to provide an innovative group decision making model for Internet-based environment by integrating the concepts of social network and Delphi Method. Finally, our approach helps the users obtain the information efficiently and companies promote their products or services effectively.
