Present an algorithm based on Gert method and Monte Carlo simulation to manage and control The research and development projects (Case study: Model airplane)

Given the growing importance of project management and control issues and the benefits of choosing the right management method according to the specific type of project, The purpose of this study is to provide an appropriate method for planning and managing research and development projects. Uncertainty of activities and time required to complete each project activity, requires the project manager to use techniques appropriate to the specific nature of the project under review. In this paper, by describing the probabilistic project of constructing a model airplane according to the probabilistic conditions, a suitable algorithm based on Gert method and Monte Carlo simulation is presented in such a way that as a result the project manager can analyze the basic components from the output of the algorithm and estimate random variables such as the expected time of project completion and the average cost of completing project activities and extract the desired results to better manage and control the project. In order to provide a better understanding of the proposed algorithm, the results of using the algorithm to plan and manage the model aircraft construction project will be reviewed and explained and As a result, the expected time and cost of the project is extracted within a 95% confidence interval.
