  7. Abstract:
  8. Project Scheduling is one of the most important branches of the operational research and management science and scheduling the project activities is considered to be one of the branches of project scheduling issue. Different goals are considered in project scheduling, but financial goals are one of the most necessary criterions in this research area.This study investigates the matter of project procurement scheduling considering incremental discount model and also storehouse space limitation with the aim of minimizing the costs of ordering, maintaining and purchasing materials required for the project.Project procurement scheduling issue, restrictions included, is an NP¬hard issue. Therefore, solving it is possible only through heuristic and meta¬heuristic methods.After studying the heuristic and meta¬heuristic project scheduling methods and their performance, the genetic algorithm was chosen for this study. The components of this algorithm, including the structure of chromosome, fitness function, crossover operators, mutation and local search (in order to optimize results generated by the genetic algorithm) are described in detail.In this problem, there is a certain delivery date for the project. Completing the project before that deadline leads to a reward and completing it after the deadline leads to a latency forfeit.Furthermore, maintaining accomplished activities until the completion of the project, imposes a cost to the problem. The discount model studied in this research is the incremental discount model. Whilst in this problem a storehouse with certain space is considered for maintaining all materials.The genetic algorithm is implemented in MATLAB programming language and tested on various samples. Test results show the effectiveness of the proposed method
