چکیده    In this research, we study the multiskill resourceconstrained project scheduling problem, where there are generalized precedence relations between project activities. workforces are able to perform one or several skills, and their efficiency improves by repeating their skills. for this problem, a mathematical formulation has been proposed that aims to optimize project completion time, reworking risks of activities, and costs of processing the activities, simultaneously. a modified version of the pareto archived evolution strategy (mv-paes) is developed to solve the problem. contrary to the basic paes, this algorithm operates based on a population of solutions. for the proposed method, we devised crossover and mutation operators, which strengthen this algorithm in exploring solution space. comprehensive numerical tests have been conducted to evaluate the performance of the mv-paes in comparison with two other metaheuristics. the outputs show the excellence of the mv-paes in comparison with other methods. a real-world software development project has been studied to demonstrate the practicality of the proposed model for realworld environment. the influence of competency evolution has been investigated in this case study. the results imply that the competency evolution has a considerable impact on the objective function values.
