Abstract: This study addresses the resource-constrained project scheduling problem with precedence relations, and aims at minimizing two criteria: the makespan and the total weighted start time of the activities. To solve the problem, five multi-objective metaheuristic algorithms are analyzed, based on Multi-objective GRASP (MOG), Multi-objective Variable Neighborhood Search (MOVNS) and Pare to Iterated Local Search (PILS) methods. The proposed algorithms use strategies based on the concept of Pare to Dominance to search for solutions and determine the set of non-dominated solutions. The solutions obtained by the algorithms, from asset of instances adapted from the literature, are compared using four multi-objective performance measures: distance metrics, hyper volume indicator, epsilon metric and error ratio. The computational tests have indicated an algorithm based on MOVNS as the most efficient one, compared to the distance metrics; also, a combined feature of MOG and MOVNS appears to be superior compared to the hyper volume and epsilon metrics and one based on PILS compared to the error ratio. Statistical experiments have shown a significant difference between some proposed algorithms compared to the distance metrics, epsilon metric and error ratio. However, significant difference between the proposed algorithms with respect to hyper volume indicator was not observed.
