由于市场需求波动会对供应链双方决策及服务系统稳定性产生影响,导致企业集群不稳定,影响集群式供应链的实施与运营。针对市场需求波动下,如何维持服务系统良好的稳定性,提升供应链的整体绩效,提出了一种服务系统演化仿真模型。该模型通过Agent建模技术构建"采购-供应"二级供应链环境,将服务系统纳入到该环境中进行演化,在演化中采用"计算实验"方法对市场需求参变量调控,最后在Repast平台上对服务系统的稳定性进行动态模拟分析。实验结果表明,该仿真模型在市场需求波动对服务系统稳定性分析方面具有较好的效果。
Market demand fluctuations will impact on the actions of both sides in supple chain and service system stability,it may lead to cluster instability, influence on implementation of the cluster supply chain and operations. Therefore, this paper is directed against the Market demand fluctuations, how to maintain the service system good stability and enhance the overall performance of the supply chain. This paper proposes a service system evolution simulation model. Agent modeling technology is used to construct"purchasing and supply"a two-stage supply chain environment, and pressing the service system into the environment to evolve. Using the computational experiment method to adjust the parameters about market demand during the evolution. Finally, the stability of the service system is dynamic simulated and analyzed on Repast platform. The experimental results show that the simulation model has a good effect on analyzing the impact of market demand fluctuation on the evolution of service system.
