The logistics facility decisions may be the most critical and most difficult of the decisions needed to realize an efficient supply chain since these decisions have significant effects on the logistics costs generated in the logistics network. We establish a logistics super network equilibrium integrating urban logistics facilities with members of traditional supply chain network, using the variational inequality theory. This model takes into account the behavior of logistics facilities and the transactions between retailers and logistics facilities are examined in this paper. Furthermore, we obtain the equilibrium condition of the system, and the economic explanation and algorithm are given. Finally, some verification examples are provided to verify the solution and decision-making application.

In this paper, we consider an algorithm for variational inequality(VI) problem on the supply chain network equilibrium model, which is established by Dong et al.. To this end, we first develop a global error bound for VI, which can be taken as an extension of the existing global error bound for VI, then present the convergence analysis of the method for solving the variational inequalities, and the convergence rate are also given under same conditions.

This paper developed a three-level supply chain network equilibrium model with multi products and multicriteria based on corporate social responsibility through integrating the maximization of economic benefits, the maximization of social utility and the minimization of environment pollution under revenue-sharing contract. We analysed competitive behaviour of manufactures and retailers in a no cooperative competitive and described the multicriteria decision-making behaviour using Nash equilibrium theory and the weighted value function. Using product utility functions of brand differentiation and consumer preferences from product price, transaction cost and corporation social responsibility to analyse product choice in a market, and we developed the optimization conditions of each tier and whole network by variational inequality method. At last we illustrated the model with several numerical examples.

Based on Stackelberg's master–slave game theory and green index decision-making conditions, this paper studies the benefit coordination of a supply chain network composed of a business flow network and logistics network, discusses the decision-making behavior of the main body of the supply chain network under the performance of green contracts or speculative behavior, respectively, and further constructs the supply chain network collaborative benefit coordination model under the guidance of a manufacturer considering a green development index. The supply chain network interest coordination model analyzes the relationship between the dominant manufacturer behavior and the supply chain network green index and network profit. The results show that fulfilling green contracts helps improve the profitability and sustainability of supply chain networks. A counter-intuitive but interesting result is that the dominant manufacturers increase the cost-sharing ratio or penalties of the logistics network, which will reduce the profit level and green index of the logistics network, and increase the cost-sharing ratio or punishment of the suppliers. Strength will increase the profitability and green index of the logistics network. Finally, we validate the relevant conclusions of the model through numerical simulation analysis.
