Abstract: Most projects significantly fail to achieve the corresponding pre-determined objectives due to uncertainty. There is wide agreement that the risk response strategy selection is an important issue in project risk management (PRM). This paper proposes a fuzzy multi-objective method for solving the risk response strategy selection problem. A linear integer programming has been used to solve a problem in order to choose the appropriate risk. An optimisation model is developed, which integrates several critical elements that are the project cost, project schedule, project quality and another objectives. The relationship between responses during implementation has been considered in this study. The time and quality saved by implementation of each of the responses in the activities have been considered in an uncertain and fuzzy manner and Zimmermann method has been used to solve the problem. Finally, a case study related to petroleum projects has been presented and the corresponding results have been analysed.
