A Fuzzy Model of Ranking Risks at Petropars Company's Excavation of Oil Well Projects

Naturally all activities are along with risk and uncertainties. Project risk has the concept more than the financial concept. In project management, risks are events that can occur during the project implementation and has negative effects on project completion and meeting goals. Identification, analysis, prioritizing and having plan for dealing with these events are playing an important role in project success. Project management body of knowledge (PMBOK) illustrates a systematic approach for implementation of risk management plan that can be lead to minimization of probability or impacts of undesirable outcomes to project goals. On the other hand appearing risks implies that project is done in an uncertain environment. Fuzzy computations are a suitable tool for dealing with these uncertainties. In this paper, possible risks in implementation of excavation of oil well project are identified and then measured and ranked by fuzzy approach.
