  7. Abstract:
  8. The subject of project scheduling is one of classic subjects in project management, and It contains the wide range of optimization problems. Using making changes in variables and constraints , it is possible to create new problems which seem better in the real world. Project tasks need resources for implementation. In some cases, it is considered that any time there are enough resources. In some other cases, it assumes, resources are limited, and resource optimum purchasing is the purpose, which this kind of issues is named resources investment problems (RIP). In this research it assumes, project necessary resources, are rented and renting costs depends on the time of owning. In standard resource renting problems (RRP) it assumes objective function is only consists of cost, and time computation of fee & interest rate is not considered, but in this research in order to make operational in real world, rate of interest gets interred somehow in the model, so objective function instead of cost or time minimization would be Net Present Value (NPV) maximization. Also in this research, instead of only usage of payment model at the end of project (LSP), incomes of project is somehow considered contemporary, and gets interred in the model, so the new model could be applicable in all projects.This problem is considered as one of the most difficult problems, which the time of solving increases with adding more dimensions. Therefore in order to solve it, Meta heuristic algorithm of Genetic is used and in numerical analysis, the differences between classic methods and heuristic algorithm will investigate. Since the output of Genetic algorithm is only tasks optimum scheduling, so in addition to use of Genetic algorithm, another algorithm is used for determination the optimum policies of resource renting
