台灣營造工程總指數自2016年起，每年上漲約1~3%，但2021年總指數年增率10.94%，材料與勞務類數值攀升情形皆異於往常。彙整過去文獻，發現在一般經濟環境下，廠商投標主要考量標案特性(專案規模、類型)、過往經驗(相似的專案、營利紀錄)與公司現況(財務狀況、工作量)。
本研究由134份問卷確立台灣營造業承包商，於物價攀升的環境下投標時考慮的關鍵因素，並根據相對重要性指數排序。結果發現，在物價波動劇烈的環境下廠商更重視「足夠的勞動力可用性」與「施工材料可取得性」，市場環境的改變，導致廠商需針對特定可用工料資源詳細評估，不再單靠過往經驗，因此本研究結合模糊集合理論發展投標決策模型，將每項因素針對「此因素對投標決策的影響程度」和「此因素在欲投標的專案中具備程度」兩項指標進行五等量表評估，並透過簡易計算將模糊語意轉換成函數值，供廠商更系統化的進行投標決策評估，減少人為主觀判斷產生的失誤。

Construction Cost Index (CCI) has been increasing by 1~3% per year since 2016, but the 2021 CCI annual rate of growth climbed 10.94%, and the rise in materials and labor services was unusual from the past. summarized past literature, it is found that contractors consider the “project size”, “project type”, “experience in similar project”, “Past profit”, “availability of required cash” and “current workload” in the general economic environment.
In this study, 134 questionnaires were used to identify the key factors that Taiwan construction contractors should consider when bidding in a High-Inflation environment, and ranked according to the relative importance index. The results of the study found that in a high-inflation environment, contractors paid more attention to “sufficient labor” and “construction materials availability”. Changes in the market environment led contractors to make detailed assessments of available of specific materials and resources, instead of relying solely on experience. Therefore, this study uses the fuzzy set theory to develop a bidding decision model, and converts the fuzzy semantics into function values through simple calculations, so that contractors can evaluate their bidding decisions more systematically and reduce errors caused by human subjective judgments.
