Abstract: With the expansion of construction project enterprise's scale, multi-project management has become one of the important problems in the development of enterprises, which plays a very important role in achieving organization’s sustainable development. In this paper, the resource-constrained multi-project scheduling problem is analyzed on the basis of resource-constrained project scheduling problem firstly, then the framework and mathematical model for resource-constrained multi-project scheduling problem are proposed, and an improved genetic algorithm focusing on probability of crossover and mutation is designed, and the effectiveness and feasibility of the proposed genetic algorithm is validated by a case study, which provides a new way for the modern enterprise to make decisions for the resource-constrained multi-project scheduling problem.

Key words: genetic algorithm, resource-constrained, multi-project scheduling
