Solving resource-constrained project scheduling problem using genetic algorithm

الملخص EN

Due to the combinatorial nature of the resource-constrained project scheduling problem (RCPSP), there is a lot of artificial intelligence methods proposed to solve it.

The Genetic Algorithm (GA), one of these methods, is considered to be a valuable search algorithm capable of finding a reasonable solution in a short computational time.

The primary objective of this paper is to build a genetic algorithm for solving RCPSP problem aiming at minimizing project’s makespan.

Based on a comprehensive review of different GAs and a full factorial experiment, a proposed GA has been presented.

The proposed algorithm has been tested on a well-known benchmark (PSPLIB).

The computation results show that the proposed GA outperforms many published algorithms and on average performs as well as other algorithms.

Also, the performance of the algorithm improves in solving large scale problems
