;This study focuses on the improvement plan of the assignment and arrangement of work shifts and processing machines and engineering costs, required by a building stone construction project of a construction company. The performance of the assignment and arrangement done manually by the in-charge could vary with the competency of the in-charge, which could result in the loss of cost and time. The study is to ensure the efficiency of the assignment and arrangement of work shifts and processing machines and the lowest construction cost, for a building stone project.
This study focuses on developing a model, built by LINGO 17.0 and Microsoft Excel 2016, which can apply to the management of stone construction projects. By inputting key parameters to the model, such as the constraints of construction time, various work types and work shifts, and performance variance of different work shifts, the model can find the minimum construction cost through sensitivity analysis of various construction arrangements and assignments. The model can provide optimized data for decision makers to compare and make better decisions more quickly.
