This paper presents a multi-mode resource-constrained project scheduling problem (MRCPSP) with maximizing the net present value (NPV) form the project contractor’s point of view. Positive and negative cash flows are considered in this model. Furthermore, to make the model close to the real situations, four different models for positive cash flows are considered. Two meta-heuristics, called simulated annealing and genetic algorithms, are used in order to solve the proposed model of the forgoing problem. To schedule all activities, a bi-directional scheduling generation scheme (SGS) for the multi-mode version is proposed, and the activity list structure selects for presenting a permutation of activities. Finally, computational results for a set of test problems taken from the project scheduling problem library (PSPLIB) are presented and discussed.
