Abstract

Abstract: 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%.

Key words: community elderly service supply chain, single-chain type, cluster type, cross-chain collaboration, system dynamics
