摘要:	中小型營造廠因資源有限，無法像甲級以上營造廠有較多的專業人才及資訊系統，可就標案進行分析，尤其在同業殺價競爭下，如何有效運用公司現有資源，進行標案的選擇及人員指派，以期獲得最大獲利，實為中小型營造廠經營者最重要的課題。小型公共工程等標期及工期一般均不長，故需要一簡單快速工具協助過濾及選擇標案，承攬後可對公司提供最佳獲利。本研究以中小型營造廠短期間承攬標案的選擇與工作人員指派為範圍，在整數規劃的架構下，建構一套最佳化數學模式，協助經營管理者在外部條件及內部資源等相關限制下，執行最佳化的標案選擇及內部人力分派，使公司獲得最大的利潤。當外部條件及內部資源限制條件改變時，本研究模式可隨時依最新條件調整參數，重新進行標案選擇及內部人力分派方案。在求解方式上，本研究將各標案之基本資料及內外部限制條件訂定參數及限制條件，將資料以EXCEL軟體方式輸入LINGO8.0套裝軟體求解，即可得各標案的選擇及人員指派最佳化獲利之結果。經以某營造廠為範例測試，其結果與人工決策方式比較，除快速外，獲利亦顯著增加。對經營者而言，本研究模式可作為一良好的決策輔助工具。 Due to resources limit, middle and small construction firms, unlike large construction ones, don’t have many professionals and complete information system to analyze cases . Especially, while other similar companies offer lower prices for competition, how to make use of the existing resources effectively, choosing cases, and appointing personnel have become the most important topic for middle and small construction firms.For small-scale infrastructure, time-limits for submission of tenders and the contracted progress schedule will not take too long. Thus, in order to get the best profit, it requires an easy and fast equipment to filter and choose from different cases. This study comprehends choosing cases in a short period and staff appointment for middle and small construction firms. Under the structure of integer programming, build up an optimal decision model to assist managers to choose the best cases and make the biggest profit for company. When the exterior conditions and interior resources alter, this research model can modulate parameters, based on the latest conditions, to re-choose cases and interior personnel appointment. In methods of solving, this research stipulates parameters and restricted conditions based on every case’s fundamental information and interior and exterior restricted conditions, and input data, in EXCEL form, to LINGO8.0 software. Then, we get the choice of every case, and the outcome of optimal profit. Testing a construction firm in this model and contrasting the outcome with personal experience and policy, in addition to being efficient, the profit increases significantly. For managers, this research model can be eminent equipment for assisting policy making.
