碳排放量扰动下两级再制造闭环供应链动态模型研究

为探索碳排量对闭环供应链产生的影响,将碳排放量作为罚利润值的形式进行研究,构建了以碳排放罚利润扰动下的两级再制造闭环供应链动态模型。通过数值模拟,比较分析了有无碳约束两种情况下的闭环供应链利润趋势,并讨论了在不同碳排放罚利润值扰动下的产品回收比例、利润分配、生产商和再制造商产量的变化。研究结果表明,随着碳排放罚利润值的增大,再制造商产品逐渐取代生产商产品,闭环供应链的利润流向再制造商,这意味着产品回收再利用能有效减少闭环供应链的碳排放量。

The Study of Dynamic Closed-Loop Supply Chain with Two-Echelon Remanufacturing under Disruption of Carbon Emissions

In order to explore the relationship between carbon emission and Closed-Loop Supply Chain (CLSC), carbon emissions was used as a penalty factor of profits, and a model of dynamic CLSC with two-echelon remanufacturing under disruption of carbon emissions was set up. Using numerical simulation, the model compared and analysised the trends of profits under the condition of carbon emissions and those without, and discussed any significant influences on products recovery ratio, distribution of profits, production changes of remanufacturing and manufacturer under different values of profits penalty. The result shows that with the increasing values of profits penalty, the products made by manufacturer would substitute those made by remanufacturing and the main profits of CLSC flowed to remanufacturing, which indicates that products recycling presents effective and decisive effect on shrinking carbon emissions of CLSC.
