dc.description.abstract對防波堤工程而言,如何規劃及運用現有資源,以最經濟的方法,在工程期限內,完成石料調派工作,實為營造廠業者之一重要課題。 本研究針對防波堤工程之卵塊石調派問題,在給定的供需及相關運輸限制條件下,利用線性規劃技巧,發展一最佳化模式,以期幫助業者求出每月最佳的卵塊石進料及拋放排程及求得最大獲利。 本研究建構之實數線性規劃數學模式,可經由LINGO®套裝軟體求解。而本研究以該軟體內建之程式語法建立線性規劃之目標式及限制式,並以介面函數直接由試算表表格中匯入所需參數值,求解完成後直接將演算結果匯出至試算表表格,取代以往相關研究以文字形式輸入軟體求解,再將輸出結果表格化,提升模式建構之效率及準確性。 經由本研究之敏感度分析機制,工程管理者可依據各參數之敏感度變化趨勢,主動調整卵塊石進料分配方式及增減石料拋放施工機具資源配置,以配合其他項目的限制條件;甚至可重新檢討局部時段的作業時間,進而修改整體施工進度網圖,以達到充分利用資源、節省成本的目的。 本研究之模式適用於長期及週期性之供應/需求調派情況。在實際之執行過程中當現場施工條件改變時,可隨時依最新條件調整參數,重新規劃排程。為測試模式之績效並同時展示模式之應用,本研究係以台灣電力公司北部某防波堤工程為例,進行實例測試,結果顯示本研究模式應可為實際應用的參考。zh_TW
dc.description.abstractFor mound type breakwater constructions, how to plan and use the current resources to allocate different types of the rock in the most economical way within the deadline is an important topic for the project manager. Given different types of the rock supply/demand and related transportation constraints, this research is useful for the project manager to solve for the optimal solution of monthly rock allocations and attain the highest profit. As for the solution, this research model can be directly output by inputting LINGO package software. Using the internal syntax from the software to establish objective function and boundary conditions to solve the linear programming, and instead of explicitly listing the data in the text of the model, the reserch using the interface function to import data from the desired spreadsheet and automatically perform spreadsheet exports when the model is solved. These skills really raised the model’s efficiency and accuracy compared with the former research. In the real working environment, the resources and limitations in all respects are not unchangeable. Through the sensitivity analysis model, the manager can automatically adjust the construction condition or resource distribution to match up other item’s limitations according to the changing tendency of every parameter’s sensitivity. Moreover, partial operation time can be reviewed again to modify the schedule diagram so that the resource can be fully utilized and cost can be saved. This research’s model is suitable for the long-term and periodical supply/demand allocation. In the real process, when the construction conditions change, the parameter can be adjusted and schedule can be rearranged. To test the model’s performance and to demonstrate the application of the model, we perform a case study concerning the mound type breakwaters of TPC on the north coast of Taiwan. The results show that the model can be useful in actual operations.en_US
