摘要
考虑虚拟企业的风险中的随机因素并将其描述为随机变量,提出了一个虚拟企业风险管理的机会约束规划模型.此类模型可以比较好地描述管理者的风险偏好.针对该模型,设计了嵌入蒙特卡洛模拟的粒子群算法,蒙特卡洛模拟是处理模型中随机变量的有效方法.仿真分析表明了该模型对于虚拟企业风险管理的重要作用以及该算法的有效性.
By considering the stochastic factors of risk :in virtual enterprise (VE) and describing them as random variables, a chance-constraint programming model is proposed for risk management of VE. One of the great advantages of this class of model is that it can exactly describe the risk preference of the manager. A particle swarm optimization combined with Monte Carlo simulation (MCS-PSO) algorithm is designed to solve the proposed model, as Monte Carlo simulation (MCS) is an effective method to deal with those random variable,; in the model. Simulation analysis shows that the proposed model is very useful for risk management of VE and the MCS-PSO algorithm is very efficient.
