双驱动式废弃品逆向供应链激励机制仿真

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。

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

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.
