The result of improper risk allocation is increased ‎costs, project delays and services, which cause loss of value-for-money for the public interest. This paper introduced a decision support system based on the graph model for systematically resolving construction risk allocation. In this model mainly assumed success of a contract needs to ‎agreement on how risks are allocated by parties. The graph analysis process considers ‎the decision-makers, their decision options, and their relative preferences when modeling ‎risk allocation negotiation as a game theory problem. Owners could also use the model to perform an in-depth stability analysis in order to ‎ascertain the ‎possible compromise resolutions or equilibrium. The model predicts the sequence ‎of decisions that took place in the dispute and furnishes an array of useful strategic insights ‎about the risk allocation renegotiation. Moreover, the model to determine how ‎changes in preferences can affect the equilibrium results executes a sensitivity analysis. This risk allocation procedure is ‎useful for both researchers and practitioners to better deal with the dispute-prone nature of ‎ construction contracts.‎ UR - https://ceej.aut.ac.ir/article_4508.html L1 - https://ceej.aut.ac.ir/article_4508_c24ef7ab17b6d7c2b34d9370498d026c.pdf ER -
