摘要:	鋼結構橋梁塗裝工程之人機派遣方式，往往是以過往施工經驗平均分配原則下安排，而無法合宜安排並導致不必要施工成本支出。本研究係依五跨連續鋼橋工程案件中，以鋼橋塗裝協力廠商之機具派遣為研究範圍，利用線性整數規劃最佳化模式，為求出人力安排及機具進場指派時機，提供分包廠商調度運籌之參考，以達最少成本為目標；依各參數之敏感度變化趨勢進行敏感度分析，藉此求得工作廠房需要之人力、機具之最少值，達成人力機具充分運用之目的。並以最佳化模式所求得之派遣結果與一般人工經驗派遣進行比較，以驗證本研究最佳化模式產生的派遣結果，相對比較人工經驗安排較具效率且控制成本。故本研究可適宜使用於鋼橋塗裝與機具派遣檢討等規劃問題，並可協助分包廠商規劃。;The man and machine dispatching for the coating project of steel bridges are often under the principle of equal distribution based on the previous experience, which may be inappropriate and cause unnecessary cost expenditure. This paper explores the dispatch of machines and tools by the third-party in the coating project for a five-span continuous rigid frame bridge. By using linear integer programming to reckon the best timing for arranging man power and machines to station in the site, it expects to offer references for decision-makers in planning and management, so as to realize the minimum costs. With the sensitivity analysis based on the changing trend of sensitivity of each parameter, it computes the minimum value of required man power and machine in the workshop, to achieve the full utilization of man power and machine. Besides, it also compares the results obtained from the optimal pattern with that from common experience, verifying that the formers can effectively control the cost. Therefore, the research results are applicable for the planning of man and machine dispatching in the coating of steel bridge and help the decision-makers in planning.
