Risk allocation is a strategic decision in project management. But the examination of the practical experience of managing construction projects shows that the process of allocating risks is generally based on the personal judgments of employers, so increases the cost and time of the project. The purpose of this article is to provide a quantitative model for selecting the optimal allocation of project risks, in a way that provides a balanced model agreed upon by all contractual parties. To design the proposed model, by analyzing the behavior characteristics and expectations of the employer in the process of risk allocation, three goals: 1) transferring the risk to the most capable agent, 2) paying the lowest cost of risk management and 3) achieving the lowest level of risk for the employer. has been introduced. Then, by developing quantitative functions to measure these three goals, a multi-criteria decision model is presented that can measure the degree of achievement of the employer's goals in different patterns of risk allocation. By receiving the judgment of the decision maker in the form of qualitative criteria, the proposed model evaluates different risk allocation options and achieves the most appropriate project risk allocation pattern in the form of a Pareto optimal curve. The proposed model in a A case study has been implemented and its results have been compared with some of the most widely used risk allocation models. The results of this model show that achieving a balanced pattern of risk allocation that satisfies the interests of all parties in the project requires attention to the conflicting goals of the employer. While focusing on transferring the maximum risk to the other party, it will increase the project costs and eventually not achieve other time and financial goals of the project.
