双驱动式废弃品逆向供应链激励机制仿真

Simulation of Incentive Mechanism Simulation on Reverse Supply Chain of Waste Products Based on Dual Drive

针对废弃品逆向供应链各主体由于收益不同导致协调失灵的现状,构建了基于系统动力学的居民、垃圾处理机构和生产企业三方演化博弈模型。使用Vensim仿真软件建立以三方策略选择概率为水平变量的存量流量图,在外生变量为常数和存在时间趋势的情况下,分别进行仿真,得出在无外界干扰情况下三方主体的策略演化路径。通过灵敏度分析,找出对主体策略产生主要影响的外生变量,并据此设计由垃圾分类驱动,市场机制拉动的双驱动式供应链激励机制。

In view of the current situation of coordination failure caused by different benefits of different entities in the waste reverse supply chain, based on system dynamics, a three-party evolutionary game model of residents, waste disposal institutions and production enterprises is constructed. Vensim simulation software is used to establish the stock-flow chart with the strategy selection probability as the horizontal variable. In the two cases of exogenous variable in constant and a time-trend, the simulation is carried out separately, and the strategy evolution path of the three parties is obtained without external interference. Through sensitivity analysis, the exogenous variables having a major impact on the main strategy is fixed, and a dual-drive supply chain incentive mechanism driven by garbage classification and market mechanism is designed.
