多供应链竞争背景下的重组应对成本干扰

Under background of multi-supply chain competition,use Supply chains which produce and retail homogeneous products as object of research,and manufacturing enterprises are their core.Establish equilibrium model before and after cost disruption by variational inequality and Nash game theory,then we give reformation condition and build reformation equilibrium model.Finally,through number example, models effectiveness is proved.
