Investigation and evaluation of Project risks based on BWM

Uncertainty is inherent and inevitable component of projects. Existence of risks and uncertainties in projects leads to decline in accuracy of estimating targets appropriately and reduction in projects efficiency. In this way, achieving to a tools that can evaluate project's risk level and as a result of this estimate real deviation amount is very essential. Hence, needs to understanding and managing risks in projects is quite clear. Identification and treatment to risks in project is one of the project manager's problems. Because of existence restrictions in projects, Identifying and prioritizing is main problem in risk management that is necessary to take place for successful risk management. The aim of this research is providing an approach based on MCDM method (BWM) which is known as a novel MCDM method, in order to prioritizing project risks and also Risk Breakdown Structure approach which structuring risk identification process and can enhance identification phases from coverage on project's characteristics and aspects view. For this purpose, at first by using risk breakdown structure and known related models, risk evaluation criteria extracted In the form of a case study which has conducted in sikas park project of Pishgaman kavir yazd Group. Then this risks evaluated by using BWM and experts ideas and finally related risks to the important criteria extracted and some strategies demonstrated to manage them.
