Study On The Combined Optimization And Coordination Problem Of Entities Under Intelligent Logistics Condition

With the development of economy globalization and severity of market competition,modern enterprises face great changes.Market competition among enterprises has changed into the competition of supply chains.With the development of information technology and intelligent technology,modern logistics is developing toward intelligence and integration.Under intelligent logistics condition,the operation pattern of supply chain has changed radically,Supply chain entities share information to each other,make decision together,and take the supply chain optimization as their goals. So the optimization and coordination problem of supply chain entities becomes an important topic to research.In the paper,optimization and coordination problem of supply chain entities under intelligent logistics condition is studied,with combined method of theoretical and empirical analysis,as well as qualitative and quantitative analysis.In addition,related theories and methods are utilized,including system science,complexity science, management,economics,and control theory.New characteristics of business entities under intelligent logistics condition are analyzed systematically.Moreover, coordination and optimization problem of entities is analyzed from the perspective of entity association and stability of the supply chain.Firstly,the definition of intelligent logistics is given,and it is proposed that intelligent logistics is the advanced stage and inevitable trend of logistics.Moreover, the complexity and dynamic character emerged from supply chain are analyzed with CAS theory and methods.Next,competition and game relation of the supply chain entities are studied.On the same time,association analysis is introduced into supply chain area,and association evaluation model of supply chain entities is built.In view of insufficiency of the traditional criteria,criteria of the paper are divided into attractive and interactive criteria, which stress the cooperation and coordination ability of entities.Then the warehouse and distribution enterprise are taken as research example.Finally strongly associated criteria are chosen after association evaluation with actual data of enterprises to help supply chain entity make decisions.Thirdly,research is focused on associated stability.Especially associated stability analysis with Lyapunov exponent is emphasis of the paper.On the basis of stability analysis of nonlinear dynamics system,related methods are introduced to judge supply chain stability.From research,crucial criteria affecting system stability are identified. Then satisfying supply chain stability,influence relations are discussed between associated criteria and related parameters in detail,which helps to study the ability to turn back to stability when supply chain is unstable and to improve the mechanism to optimized control.Stability theory is introduced to the area of supply chain profit allocation,and new profit allocation method based on Nash negotiation model and system stability judgment is built.It is put forward from the cooperation perspective that enterprises profit allocation should guarantee the supply chain stability.At last the paper makes conclusions and gives a brief discussion about future research direction.
