"身為營造工程的業主最困難的決定之一即是選擇營造承包商，選擇了不恰當的營造承包商可能會發生工程糾紛、造成無法履約等狀況，這對業主而言常造成時間、金錢甚至商譽的損失。
以台灣而言，現今合格設立之營造承包商的家數已達一萬六千多家，按理應有眾多廠商可供業主選擇，可是營造業在歷經了多次產業景氣榮枯的循環後，現今低價搶案的風氣興盛，以致造成履約糾紛仍頻傳。因此，如何篩選出潛在不恰當的營造承包商是業主在招標過程中非常重要的步驟，而營造承包商的資格預審機制則是業主在招標時可運用的最佳方法。
營造承包商資格預審機制是一個多面向(包含定性和定量)標準的審查流程，通常是將各面向影響因子評分加權後總計分數作為決定判斷依據。不過，以往各面向影響因子的權重通常是由業主或建築專業人士所建議或設定，並不具有科學標準，因此使得資格預審機制常令人詬病。
因此本研究將使用層級分析法（AHP），將各面向影響因子轉為層級結構，並將各影響因子之相對優先等級量化為的相同比例尺度的權重，以提供合適的模型供業主在招標時可計算各投標承包商的加權總計評價以做為決策時的參考。"

"One of the most difficult decisions for the owners of construction projects is to select the contractor. Selecting an inappropriate construction contractor, disputes and not performing may occur. This is often caused by damage to the owners’time, money and even goodwill.
In Taiwan, low-cost ethos is flourishing, which results in some construction companies’ failure to survive. Thus, how to screen out potential failure contractors from the bidding process is very important for the project owner. The prequalification of the contractors plays a prominent role in solving this problem.Contractor prequalification is a multi- criterias (includes qualitative and quantitative) standards review process, which total the weighted score for each factor as a judge. However, the weights of the factors are usually suggested by the owners or professionals, they are not getten by a scientific standard process. And, it is often criticized for the prequalification.
Therefore, this study will be used the Analytic Hierarchy Process (AHP) to calculate the weights of the each factors in order to provide a right model for the owners. It can be a reference when bidding decisions making ."
