    [[abstract]]商展是很重要的溝通工具之一。在資訊快速發展的今天,在各產業中皆存在著許多種類的展覽,例如:區域性展覽、國際性展覽、專業展以及綜合展。對企業而言,如何有效並客觀地評估以及選擇展覽參加是一項重要的課題。本研究建構一套鍛造產業評選展覽的模式與層級架構,經由文獻探討,以及交易成本理論、關係行銷與組織採購行為觀點出發,進而評估展覽的合適性,以供鍛造產業做出決策上的選擇或修正。 為了提高決策效率與正確性,本研究採用模糊語意偏好關係法,來衡量選擇展覽之各構面與因素的權重值排序。模糊語意偏好關係法除了保有偏好關係法在成對比較上具一致性外,透過模糊語意的加入,更能客觀地反映專家判斷。 結果顯示,權重值最高的構面為展出型態、因素為目標特性,而專家判斷以此評選層級架構為基礎,評選出得分值最高之展覽。這代表此展覽能滿足鍛造廠商的觀展目標,也期盼未來鍛造協會之成員在評估出席哪些展覽時,能特別留意此展覽的相關資訊。[[abstract]]As we know fair is a very important communication tool so in this day with information developing rapidly there are many different kinds of trade shows in various industries such as regional fairs international fairs professional fairs and synthesis fairs To firms it is important that how to evaluate efficaciously and objectively and select the fair to attendance For this purpose this study builds a hierarchical framework of selecting and evaluating a fair for the forging industry to make a right decision basing on the theory of transaction cost and the view of relationship marketing and Organizational buying behavior to examine the suitability In order to boost the accuracy this study adopts the method of the fuzzy linguistic preference relations to examine the weight of criteria of each dimension and factor for a fair performance Besides keeping the consistency of paired comparison in preference relations the fuzzy linguistic preference relations can reflect the experts’ judgments objectively involving the fuzzy linguistic The result shows that the dimension with the highest weights is the displaying type of show and the factor with the highest weight is the characteristic of goal Experts’ judgments which base on this hierarchical framework of selecting and evaluating find the highest score’s fair That presents this fair can satisfy the goal of visiting fair from the forging factory and it is also hoped that forging association members could be pay special attention to the related information about this fair when they evaluate which fair should be attende
