| dc.description.abstract | In recent years, the domestic sand and stone shortage and environmental awareness is rising, according to domestic and foreign research in the same floor area, compared reinforced concrete (RC), steel reinforced concrete (SRC) and steel structure (SS) carbon dioxide emissions, found that the use of steel structure its lowest CO2 emissions, plus recycled renewable green building materials. At present, Taiwan′s social labor age generally shows aging and rely on foreign migrant workers, through education, young people no longer seek labor-intensive work, resulting in the generational convergence problem is becoming more and more serious, so that the construction site steel industry is facing technical faults, lack of work, factory delays in delivery and so on ... issue. However, site welding operations are the key path of project progress, and we need to complete the assignment of welding operations within the limited space, duration and budget of the site. Among them, manpower, tools, work areas, duration, work planning due to many constraints, it is difficult to optimize decision-making after all. How to arrange work more efficiently and at the minimum cost is a subject that needs continuous study.
This study uses optimization theory to analyze and evaluate, consider the site welding restriction conditions to construct an integer planning model, using LINGO 17.0 software to find the best solution, supplemented by Microsoft Excel 2016 trial balance editing assignment results. Finally, this study takes the welding machine assignment of steel building as an example test, and compares the results with manual assignment, it is true that this research model is more cost-saving and more efficient, using sensitivity analysis, the change of parameters increase or decrease and cost, which can be used as an important reference for managers′ cost control and personnel and equipment resource allocation. | en_US |
