Review of the Layout Optimization of Temporary Facilities

The layout of temporary facilities on the construction site is an important content of construction organization design and construction site management. Since the 1990s, it has been continuously concerned by many scholars. This article systematically reviews and analyzes relevant literatures from the dimensions of problem classification, assumptions, objective functions, constraints and optimization algorithms of mathematical models for facility layout problem, exploring the current situation, future trends, and research directions in the field of optimizing the layout of temporary facilities on construction sites. Results show that how to make the mathematical model be more consistent with the engineering practice and explore the optimization algorithm with higher accuracy and efficiency are the key points in this field. The future research direction from the aspects of the assumption that the conditions should be more realistic, the objective function tends to be diversified, the improvement of optimization algorithm and paying more attention to prefabricated buildings.
