Production scheduling in modular construction: Metaheuristics and future directions

Abstract

Modular construction (MC) is an increasingly important construction technique. However, it also requires the use of sophisticated scheduling algorithms. A comprehensive literature review of different scheduling systems used for prefabricated construction, was conducted using the PRISMA methodology. Over 500 relevant papers were analysed and 59 critical applications of production scheduling metaheuristics were closely examined. However, very few of these were for modular construction. This paper provides a deep analysis of GA applications in scheduling and the newer techniques using PSO, SA and ACO. The results of the review suggest 6 directions for future research namely, (i) Consideration o..
