基于系统动力学的集群式社区养老服务供应链跨链协作模型

摘要

In order to solve the problems of low resource utilization rate and imbalance of supply and demand for community elderly service supply chain, a single community elderly service supply chain model and a cross-chain collaboration model of community elderly service supply chain are built based on the method of system dynamics. Then selecting the total resource amount and balance ratio of supply and demand as the evaluation indexes, a comparative simulation is made. The simulation results show that compared with the community elderly service supply chain, the cross-chain collaboration model of cluster community elderly service supply chain can on the one hand reduce the total resource amount and maximum fluctuation of each supply chain in cluster system by 10％ and 40％, and on the other hand the cross-chain collaboration model of cluster community elderly service supply chain can increase the balance ratio of supply and demand by 15％, and reduce the amplitude of fluctuation by 27％.%为了解决社区养老服务供应链中存在资源利用率低和供需不平衡的问题,运用系统动力学的方法构建需求扰动情况下单链式社区养老服务供应链模型和集群式社区养老服务供应链跨链协作模型,并选取总资源量和供需平衡比为评价指标进行对比仿真分析.结果表明:与社区养老服务供应链相比,集群式社区养老服务供应链跨链协作模型,一方面能够将集群系统中每条供应链总资源量的均值和最大波动幅度分别降低10％和40％以上;另一方面能够将供需平衡比的均值提高15％以上,并将波动幅度降低27％左右.
