摘要
将以往仅考虑成员企业间竞争的闭环供应链网络优化设计问题,扩展到考虑闭环供应链间竞争下的网络优化设计问题,网络中的运作成本不再局限于线性成本,而是处理非线性成本,且在网络优化设计中采用连续变量。基于再制造闭环供应链的关键功能活动构建再制造闭环供应链间竞争下的网络结构,基于功能活动弧段设计运作与回收成本和设计成本函数,利用均衡理论描述再制造闭环供应链间的竞争行为,利用变分不等式理论建立基于连续变量的再制造闭环供应链网络设计模型。利用提出的模型结合算例优化设计再制造闭环供应链网络,并分析再制造率对各条再制造闭环供应链销售额、运作与回收成本、设计成本和利润的影响,以及对各需求市场需求量、回收量和价格的影响。
The aforementioned closed-loop supply chain network design models consider only competition among the member enterprises in the network. The remanufacturing closed-loop supply chain network design model is developed extends the aforementioned models to consider competition among closed-loop supply chains. The design model is not limited to linear costs, but, rather, which can handle nonlinear costs. Moreover, continuous variables are used first in the model formulations. The network considering remanufacturing closed-loop supply chain competition based on crucial functional activities is presented. The operational and recovery cost functions, design cost functions is developed based on functional activity arc sections. The competitive behaviors among remanufacturing closed-loop supply chains are analyzed by using the equilibrium theory. The remanufacturing closed-loop supply chain network design model with continuous variables is formulated by using the variational inequality theory. Numerical examples are solved by using the proposed models to design the remanufacturing closed-loop supply chain network, and analyze what impact the rate for remanufacturing will have on sales, operational and recovery costs, design costs and profits for every remanufacturing closed-loop supply chain, and the demands, the amount of return, prices for every demand market.
