專業預鑄廠在面對營建業激烈的競爭環境之下，如何運用有限的的生產資源，以經濟有效的方式進行最佳的相關生產排程規劃，達到最大獲利目標，實為決策者重要的營運課題；以往決策者對承攬案件選擇與工作指派之決策方式，大多採主觀經驗或直覺判斷，往往無法有效率的利用資源，甚至有決策失當的情況發生。 本研究考慮預鑄生產及儲存運輸的模式，建構一預鑄構件生產儲運的最佳化模式，協助決策者在有限的資源限制下，進行最佳決策以使公司獲得最大收益；本研究以預鑄廠新承攬之工程專案為研究範圍，當相關限制條件改變時，本模式可隨時依最新條件調整參數，重新進行分析評估，以使公司獲得最大收益；本研究模式為一整數規劃問題，我們利用LINGO 7.0套裝軟體求解模式，為驗證模式適用性，本研究以國內某預鑄廠工程專案為範例測試，測試結果與人工經驗決策及指派方式比較成效良好，顯示本研究可靈活運用於預鑄專案生產與儲運規劃等問題，具有輔助決策者之實用性。 Under a keen competition of construction business, how to use limited resources and search for an efficient way for the optimal programming of related producing schedule to gain the biggest profit is an important topic for a policy maker of a precast concrete plant. The policy maker in the past always makes decisions according to his own subjective experience or intuition in case selection and work designation, which is usually unable to use resources effectively. Furthermore, he might unfortunately make an improper decision. This research considers the mode of precast concrete production, storage and transportation and develops an optimal model for the policy maker making a best decision to gain the greatest profit for the company. The scope of this research is based on the new-contracted projects. When the correlated constraints changed, this model would be able to adjust parameters to evaluate and analysis accordingly at any time to get an optimal solution. This research model is based on integer programming. As for the way of solution, we use LINGO 7.0 software to get an optimal result for each case. In order to verify the applicability of the model, we take a project of one precast concrete plant as a test. The test result compared with the result based on experience and assignment by intuition is obviously better. Therefore, this model can be used to solve the problems of production, storage and transportation of a precast concrete plant to assist a policy maker to make an appropriate and optimal decision.
