Multicontractor multiproject matching optimization for planning modular school construction programs.

In a practical context of construction management, a number of special contractors are selected to deliver a multiproject program in a definitive time frame. Research has yet to address how well contractors are matched to projects in scheduling and how to evaluate this criterion in scheduling optimization analysis. This research formulates a novel resource scheduling optimization problem termed multicontractor multiproject matching optimization problem (MCMPMO) based on the current practice of planning modular school development programs. The particular goal of MCMPMO is to determine which contractor is a better match for delivering which project in such a way that the program would be completed by available resources in time, resulting in the highest chances of completing the whole program to the satisfaction of all the stakeholders. A bi-objective optimization formulation for MCMPMO is proposed in the application context of planning modular school development programs. A computer program was prototyped to identify a Pareto front of the MCMPMO problem in a case study. [ABSTRACT FROM AUTHOR]
