An efficient genetic algorithm to solve the resource-constrained project scheduling problem with transfer times: The single mode case.

•This paper considers the resource constrained project scheduling problem with resource transfer times.•Very few published papers considered this problem.•A new and efficient genetic algorithm is proposed to solve this problem.•1288 test instances with respectively 30, 60, 90 and 120 activities are used to evaluate the proposed genetic algorithm.•The proposed algorithm performs better than solution methods previously published.
