溯源供应链系统的回收模式选择

Selection of Recycling Modes of a Supply Chain with Traceability

溯源系统的引入不仅为回收提供便利,还可进一步提高消费者的信任度,从而提高回收量。但不同回收模式下的回收量因受供应链各级成员溯源水平的影响会出现差异,这使得回收模式选择及供应链决策变得更加复杂和困难。因此,开展以制造商为领导者的制造商回收、零售商回收、制造商和零售商混合回收三种模式下的溯源水平、定价策略和回收量的最优决策研究具有重要的应用和学术价值。研究发现:溯源水平与溯源成本边际系数、回收成本节省和回收模式竞争程度有关。溯源水平的提高会提高批发价和销售价,降低回收价。制造商应根据消费者溯源偏好、溯源对回收的影响程度和成本弹性系数设置溯源水平。当竞争程度较低时,制造商会选择混合回收模式,否则选择自行回收;当消费者偏好高于一定阈值时,混合回收模式下回收量的提高更加明显,对环境也更加有利。

A supply chain traceability system does not only make it more convenient for product recycling but also improves consumers'trust,which can increase the recycling volume.However,due to the variation of recycling volume resulted by the traceability level of supply chain members under different recycling modes,it becomes more complex and difficult to make supply chain decisions in the selection of recycling modes.Therefore,the optimal decision-making of traceability level,pricing strategy and recycling volume under the manufacturer recycling mode(Mode M),retailer recycling mode(Mode R)and hybrid recycling mode(Mode MR)led by manufacturers was researched.The results show that the traceability level is related to the marginal coefficient of traceability costs,cost savings in recycling and the competitiveness of recycling modes.The improved traceability level can lead to an increase in the wholesale price and retail price,and a decrease in the recycling price.It is better for the manufacturer to set the traceability level according to consumer traceability preferences,the effects of traceability on product recycling,and the coefficient of cost elasticity.In a moderate competitive market,the manufacturer will choose Mode MR.As the competition aggravates,the manufacturer will prefer Mode M.When consumer preferences reach a certain threshold,the increase of recycling volume under Mode MR is more robust,and more benifical to the environment.
