Modeling a Concentration Pattern on Critical Paths in Control of Project Delays

The passage of time always makes us aware of the issues around us. Time projects also reveal the hidden issues of the project. So the logical step is to include transparent points in the project. Stopping or slowing down the project process is necessary to apply these to the project, which will delay the projects. So project managers need to tightly control project risk with reasonable costs. Existence of delays is always an inseparable part of projects and subject of fundamental disagreements among their stakeholders in all countries. As delay in projects is equal to increased costs, thus, by having delay and spending too much cost out of the pre-planned cash ow, a project can even reach a point that it will get out of prot. In the present study the researchers believes that, risk of delays should be managed, minimized, shared, transferred or accepted, but it cannot be ignored. Therefore, it must be predicted, covered, managed and optimized. Now, the fact that any delay and prolongation of project time results in signicant qualitative and quantitative costs more than the initial estimates shows importance and necessity of research in this area. By providing an innovative method with the help of the Work breakdown Structure, Baseline, Hierarchical Technique and Data Envelopment Analysis (DEA), the researchers will control the risk of projects and even prevent them from occurring.
