灰色环境下制造/再制造集成物流网络优化设计

Optimization Design on the Manufacturing/Remanufacturing Integrated Logistics Network under Grey Environment

本文考虑到制造/再制造集成物流网络中新产品与再制造产品的需求量和废弃产品质量的不确定性,用灰数来表达网络中的某些参数,从而提出了一种带有灰色参数的制造/再制造集成物流网络优化设计模型。利用灰色白化方法将灰色规划模型转化为确定型的等价类模型,并用优化软件对确定型模型进行求解。最后通过算例验证了网络设计方法的有效性。

Considering the uncertainties of the products＇ demand and the damaged conditions of disused products,a grey optimal design model of a manufacturing/remanufacturing hybrid logistics is presented by expressing the uncertain parameters with grey numbers.The grey model is translated into the specified equivalent model with the grey whitenization method.The deterministic model is solved using the optimal software.Finally,the validity of the network design method is demonstrated by a numerical example.
