It is their different value tendency of risk to hydroelectric power project thatleads to the asymmetric information of diversion schemes. So the bargaining game mechanismbetween investor and design engineer should be established to improve their awareness ofdiversion schemes. As expected monetary value decision criterion doesn’t take decisionmaker’s subjective factors during the bargaining game process of diversion schemesasymmetric information problem, the paper puts forward expected utility value criterion basedon risk analysis theory, utility theory, and entropy theory, discusses how to make risk ofconstruction diversion system reasonable configure. Under the guidance that utility value ofevery diversion time interval is equal, utility function of decision maker is confirmed and theutility losing computation model of diversion standard is put forward. Subjects ofdecision-making demand risk and its risk loss diminish by degrees with the development ofconstruction. Then considering the asymmetric information condition and that diversionstandard of every diversion time interval is floating, utility value of every diversion timeinterval is confirmed finally through the bargaining game mechanism. According to utilityvalue of every diversion time interval, risk configuration mechanism of construction diversionsystem based on bargaining game platform is established under the guidance of expectationutility losing equilibrium principle. In summary, according to the demand of constructiondiversion schemes decision, decision theory that develops from expected monetary valuedecision criterion to expected utility value criterion and risk configuration mechanism thatdevelops from the rigid one to the dynamic risk configuration mechanism based on bargaininggame platform are put forward in the paper, which helps to achieve harmonious risk balanceand its optimization of hydroelectric construction system. 收起
