碩士 === 立德大學 === 地區發展管理研究所 === 96 === Prior to the enactment of the government's procurement act,the guideline for choosing the appropriate bid was based on three traditional methods:“the lowest tender”,“the second lowest tender”,and“the reasonably offered tender”. NO matter what method is used ,a floor price is required for each procurement case.In other words ,“price”is the bottom line for selecting a bid among tenders. However in spite of its inpartiality,openness,and transparency,this method would inevitably be unable to pervent the bidders from offering unreasonably low prices just to win the bid;and then deliver the product with inferior quality. Therefore, government sectors would not purchase the products with the best quality. Disputed and controversial issuse often occur between the bidder and government. This results in an inefficient operation of procurement and a delay in budget disbursement. Hence,in the government procurement act passed by the Legislative Yuan on May 1,1998.“the most advantageous tender”is added as a guideline for selecting the appropriate bidder.This guideline would be in perfect accordance with government's determination in laying a solid foundation for procurement procedure in which the best products can be purchased from the suppliers via an impartial and open bidding selection. When carrying out the selecyion of the most advantageous tender,the following approaches are usually used:overall evaluated score method,price per score point method,The most frecuently used approaches as approved by the government sectors.The most frequently used approach is the ranking method in which decision making is made by group instead of individuals as aided by a quality/quantity analysis. This approach has been criticized and modified by some scholars. The current study is to analyze the ranking difference among the ranking method,grey relation analysis,and VIKOR method based on the evaluation materials os previous bidders. The purpose of this study is to examine the inadequacy of mathematic operation on the ranking method when using the most advantageous tender as a guideline in selection the bidder. It is also the purpose of this study to settle the disputed issuse on this regard and to improve procurement procedure.
