摘要:	目前台灣社會勞工年齡人口普遍呈現老年化，一般有專業技能的職業學校也在減少，造成世代交替銜接不上的問題日益嚴重，使得工業產業中些許產業面臨斷層、缺工、倒閉等…..嚴重問題發生。然而鋼構廠房電焊作業屬於工業產業鏈的一環，需在固定廠房內有限的空間、時間及預算內完成電焊作業指派。其中，人力、機具規劃礙於諸多限制條件，始終難以進行最佳化配置。如何更有效率的安排工作，並以最低成本完成，是各單位努力持續研究的課題。本研究應用最佳化理論進行評估分析，考量電焊作業指派面臨諸多限制條件，建構出整數規劃模型，使用LINGO數學規劃軟體，配合Microsoft Excel試算表作為分析工具進行求解。最後，本研究以本公司宜蘭某精密科技鋼構廠房作為範例測試，其結果良好，與人工指派相比，顯示本研究模式確實較有效率且求得成本更低，並進行敏感度分析，具高度穩定性和可靠度，提供決策者精確之判斷依據。 ;The age of the workforce is generally aging, in Taiwan. Vocational schools with professional skills are also declining. The problem of the inability to cope with each other from generation to generation has become increasingly serious. As a result, some industries in the industrial sector are facing serious problems such as faults, lack of work, and closures. However, steelworks welding operations are a part of the industrial industry chain. Welding assignments must be completed within the limited space, time, and budget of the fixed plant. Among them, manpower and machine planning have always been difficult to optimize the configuration due to various constraints. How to arrange work more efficiently and complete it at the lowest cost is the subject of continuous research by all units. This study applies the optimization theory to evaluate and analyze, consider the welding job assignment faced with many constraints, construct an integer programming model, use LINGO mathematics planning software, and use the Microsoft Excel spreadsheet as an analysis tool to solve. Finally, this study used the company′s Yilan Precision Technology Steel Plant as an example test. The results are good. Compared with the manual assignment, this research model shows that the research model is indeed more efficient and the cost is lower, and the sensitivity analysis is performed. High stability and reliability provide accurate decision-making basis for decision makers.
