Abstract

Project scheduling in the resource-constrained situation is one of the key issues of project-oriented organizations. The aim of Resource-constrained project scheduling problem (RCPSP) is to nd a schedule with minimum makespan by considering precedence and resource constraints. RCPSP is a combinatorial optimization problem and belongs to the NP-hard class of problems. The exact methods search the entire search space and are unable to solve a large-sized project network problem. Thus, metaheuristics are used to solve this problem in a short computational time. Due to the probabilistic nature of metaheuristics, it is a challenging problem to make a balance between exploitation and exploration phases. The literature review shows that embedding of chaos improves both the convergence speed and the local optima avoidance of metaheuristics. This paper presents a Chaotic vibrating particles system (CVPS) optimization algorithm for solving the RCPSP. Vibrating Particles System (VPS) is a physics-inspired metaheuristic which mimics the free vibration of single-degree-of-freedom systems with viscous damping. The performance and applicability of the CVPS are compared with the standard VPS and ve well-known algorithms on three benchmark instances of the RCPSPs. Experimental studies reveal that the proposed optimization method is a promising alternative to assist project managers in dealing with RCPSP.
