摘要

The construction temporary facilities layout planning (CTFLP) requires an identification of necessary construction temporary facilities (CTFs), candidate locations and a layout of CTFs at candidate locations. This study proposes a decision making system to decide on an appropriate CTFLP in large-scale construction projects to improve the operation safety and efficiency. The system is composed of the input, CTF and candidate location identification, layout optimization, evaluation and selection, as well as output stages. The fuzzy logic is employed to address uncertain factors in real-world situations. In the input stage, the knowledge bases for identifying CTFs and candidate locations are determined. Then, CTFs and candidate locations are identified in the following two stages. Furthermore, a multiobjective mathematical optimization model with fuzzy parameters is established and fuzzy simulation-based Genetic Algorithm is proposed to obtain alternative CTFLPs. The intuitionistic fuzzy TOPSIS method is used to evaluate and select the most satisfactory CTFLP in the last stage. Finally, a large-scale hydropower dam project is used as a practical application to demonstrate the effectiveness and efficacy of the proposed system.
