基于随机演化博弈的建筑工程供应链质量管理研究

为了真实反映不确定性环境下工程供应链质量管理动态变化过程，将高斯白噪声作为随机干扰项引入演化博弈，建立收益矩阵，分析业主、监理和施工等三方在不确定环境中策略选择的稳定性，并将 It?随机微分方程用随机 Taylor 展开后进行数值仿真，分析各影响因素对演化结果的影响。研究表明，三方初始意愿、违规工作被发现时整改的支出比例系数、工程质量问题发生后的损失传递系数等参数均可改变博弈主体的策略选择，而随机干扰对策略选择上的作用有利有弊。

Research on Engineering Supply Chain Quality ManagementBased on Stochastic Evolutionary Game

In order to truly reflect the dynamic change process of the quality management of the engineering supply chain under theuncertain environment，this paper introduces Gaussian white noise as a random interference item into the evolutionary game，establishes a profit matrix，and analyzes the stability of strategy selection of three parties including the owner，the supervisor and theconstruction party in the uncertain environment. The numerical simulation of It? stochastic differential equations with stochasticTaylor is used to analyze the influence of each influencing factor on the evolution result. Studies have shown that parameters such asthe initial willingness of the three parties，the rectification expenditure ratio coefficient when the illegal work is discovered，the losstransmission coefficient after the project quality problem occurs can change the strategy choice of the game player，while the randominterference has both advantages and disadvantages in strategy selection.
