Multistakeholder Conflict Minimization–Based Layout Planning of Construction Temporary Facilities

Abstract

The layout planning of construction temporary facilities (CTFs) is a specific construction site layout problem. Despite considerable research undertaken to determine satisfactory layouts of CTFs for their significance on a successful completion, conflicts between the facility layout (layout planner) and other preplanning tasks (involved stakeholders) are neglected during the best layout design process. Such conflicts are widely recognized to cause economic losses, delay projects, damage the environment, and worsen the construction quality. This study establishes a multistakeholder conflict minimization–based framework to consider conflict mitigation in the evaluation and selection processes of planning a facility layout. Simultaneously, satisfactory solutions for the involved stakeholders are selected to achieve a cost-duration-quality-environment trade-off for overall project success. Specifically, key stakeholders and the respective decision options are identified by using existing mathematical techniques in Module I and subsequently constructing a “solution pool” in Module II. In Module III, the facility layout planner analyzes the conflict structure to roughly estimate the ranking criteria values with regard to each solution, which are input into the first filtering processor to eliminate infeasible solutions in Module IV, and, accordingly, the parent solutions are shortlisted. In Module V, a moderate group is selected and a multicriteria double-Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) intuitionistic fuzzy group decision-making method is proposed to minimize the multistakeholder conflicts as well as to select the best facility layout. To demonstrate the applicability of the proposed framework, a case study is conducted on a large-scale dam construction project. The system is validated to be useful for both academic researchers and practitioners to deal with the best solution (i.e., the layout of CTFs, the plan of transport routes) selection from a global viewpoint.
