Research On Logistics Network Design Problem Considering Dual Decision-makers

Logistics network design problems have a very wide range of applications in the production,life and even military.For enterprises that rely on the network operation,the quality of network design will directly affect the way,quality,efficiency and cost of enterprise logistics service,thus affecting its profit and market competitiveness and even determining the fate of business.Especially for utility enterprises such as power system,service quality is very high and has a unique management structure.Therefore,how to efficiently design the logistics network of metering devices under the conditions of service quality is very urgent.On the other hand,the decision-making of logistics network design has always been the focus of scholars.In traditional theory of logistics network design,it is usually to consider design of the logistics network based on the potential hypothesis----centralized decision-making.However,widespread decentralized supply chain in practical logistics network design provides us a new idea.Systematic study on how to make logistics network design decision-making under conditions where dual types of decision-making body coexist has become a new research direction.In this paper,a kind of logistics network design problem considering dual decision-making body is proposed through analysis of decentralized supply chain logistics network,.We focus on how to make the decision of logistics network design and operation decisions under the background of double decision-making body.Firstly,this paper studies the double decision-making strategy of decentralized supply chain,and uses Stackelberg game theory to establish a logistics network design model considering dual decision-making under decentralized supply chain.Then,this network design model is transformed from a Stackelberg decision problem into a class of nonlinear mixed integer programming models by bi-level programming.Afterwards,two types of models are compared by establishing a logistics network design model that considers a single decision body as a control group.The decision-making of both supply and demand is optimized and overall interest of supply chain is improved by design of logistics network with double decision-making body.In addition,a genetic algorithm is used to solve this logistics design problem and sensitivity of relevant parameters is analyzed.By comparing results of dual decision-making entities model and single decision-making model,conclusion that dual decision-making entities are more applicable to decentralized supply chain is obtained.Finally,this study provides a new theoretical exploration of how to design logistics network under dual decision-making body,and improves efficiency of managers in practical supply chain.
