Abstract:
Selecting the best way to perform the project constituting activities is one of the most important issues in the project scheduling, so time and cost be proportionate with contractor or the employer's perspective to implement the project. The other hand considering that many activities in the majority of project and consequently many Choice options for activity implementation, So this choice does not possess a unique solution, But also includes a set of solutions, are not preferred None of which On the other and is called the Pareto solutions this set. Therefore, in this paper, is presented a mathematical model for project scheduling with multiple objectives based cost payment patterns and resource constraints Since this problem, is considered as combinational optimization in NP-hard problems. metaheuristic algorithm is used to solve the proposed model in project scheduling and has been evaluated for finding optimal solution by using comparable indicators algorithms performance. and ultimately for validation, obtained Solutions by the proposed algorithm were compared with the obtained exact solutions form the GAMS software. show that the obtained results the proposed algorithm are efficient and converges to the optimal solutions.
