工程風險管理行為演化博弈分析

【摘要】:在重大基礎設施工程系統(tǒng)復雜性與不確定情況下,風險管理主體的策略選擇行為與穩(wěn)定狀態(tài)往往受到其角色、利益、風險偏好和感知差異的影響。為了更好地刻畫重大基礎設施工程風險管理過程中公共部門和私人部門的行為決策動態(tài)演變過程,在演化博弈分析中引入前景理論和風險感知因素,通過前景價值和權重函數(shù)對傳統(tǒng)支付矩陣參數(shù)進行修正,分析雙方風險管理策略選擇過程和演化結(jié)果的穩(wěn)定條件,從風險感知角度詮釋雙方的行為傾向原因和穩(wěn)定策略,仿真分析不同參數(shù)對演化結(jié)果的影響。研究結(jié)果表明,雙方風險管理行為演化博弈存在5個均衡點,但是由于工程復雜性和主體有限理性產(chǎn)生的認知偏差、樂觀偏見和反射及損失效應,使得系統(tǒng)在現(xiàn)實中不易收斂于穩(wěn)定點并達到最佳風險管理狀態(tài),風險管理成本、處罰、風險損失及分擔比例等參數(shù)對雙方行為演化結(jié)果產(chǎn)生不同程度的影響,當參數(shù)調(diào)整通過臨界值時能夠影響風險管理策略的選擇傾向和穩(wěn)定性。
[Abstract]:In the case of complexity and uncertainty of major infrastructure engineering systems, the behavior and stability of risk management agents are often affected by their roles, interests, risk preferences and perceived differences. In order to better depict the dynamic evolution process of behavior decision in public and private sectors in the process of risk management of major infrastructure projects, foreground theory and risk perception factors are introduced into evolutionary game analysis. By modifying the parameters of the traditional payment matrix through the foreground value and weight function, the paper analyzes the stability conditions of the selection process and evolution result of the risk management strategy, and interprets the cause of behavior tendency and the stability strategy of both sides from the perspective of risk perception. The influence of different parameters on the evolution results is analyzed by simulation. The results show that there are five equilibrium points in the evolutionary game of risk management behavior, but due to the cognitive bias, optimistic bias, reflection and loss effect, due to the complexity of engineering and the limited rationality of the main body. In reality, the system is not easy to converge to the stable point and reach the best risk management state, risk management cost, penalty, risk loss and the proportion of risk loss have different degrees of influence on the evolution of behavior of both parties. The selection tendency and stability of the risk management strategy can be affected when the parameter is adjusted through the critical value.
