摘要

競爭巨烈的企業界進入了大變動的時代，為了生存下去，也超越以前的競爭關係與行業的框界，轉而進行評選合併、合作的方案。然而在群體決策過程中，如何評選合併、合作的對象或方案時，需考慮到的因素為管理者是否有足夠的能力來做決策，也就是本研究所謂的「決策者個人才力」與「整體最大的共識與利益」等二大因素。
聯合國安理會、國際貨幣基金(IMF)等國際組織在以投票行為，做決定重大政策時均有「一票否決，票票不等值」的現象。但在一般社會中群體決策的方法還停留在傳統，將決策者才力程度視為「齊頭式平等」，以「票票等值」的概念來決定方案的產生。故如何將「決策者才力權重」的概念，建構於層級分析法群體決策過程中，可謂一重要議題。
過去鮮少有學者提出，如依據上述的群體決策方法，本研究擬建構一套「決策者才力與偏好權重」整合模式，並將其應用在實證中。由「AAC公司-資訊委外服務評選」實證研究結果發現，本模式對於評選排序結果，與傳統AHP所求算之評選排序結果有差異性，且就整體而言與決策者的看法最一致。

The highly competitive industries have entered the era of facing tremendous changes. In order to survive through the hardship and surpass the competition and pre-defined restriction of the industry, many have proceeded to evaluate the possibility of either merger or partnership proposals. The two major factors, “managing director’s decision making capability” and “integral consensus and benefit” to be considered, whether the managing director is capable to make decisions, can also be used to evaluate the merger or cooperating partner and proposal using group decision-making.
Some international organizations such as The United Nation Security Council, International Monetary Fund (IMF), utilize voting to decide important policies, where the situations of “being denied by only one vote, or each vote with different values” occurs regularly. However, most group decision making within the society has remained to adopt a traditional way. That is to say, new proposals might have been decided by using “equal value voting” or regarding all the policy makers with equivalent abilities. Thus, implementing the idea of “priority based on decision maker’s capabilities” into AHP group decision making procedure has become an important topic for further study.
It has rarely been mentioned by previous scholars to follow the above-mentioned group decision making. This research drew out a model of integrating “priority based on decision maker’s capabilities” (WCPBC) and “priority based on decision maker’s preferences” (WCPBP) and applied it in an empirical case study entitled “AAC Company Information Outsourcing Service Evaluation”. The major finding of the study showed that the rank results evaluated by this proposed model were different from those by the traditional AHP method. However, when looking as a whole, it appears more consistent with the decision maker’s opinions.
