The Difference

In a supply chain system, the prices with which the suppliers supply its local commodity to the retailers should satisfy the requirements of the retailers and the consumers. The supply and demand scheme satisfying these requirements is reduced into fuzzy relation inequalities (FRIs) with min-product composition. Due to the difference between the min-product composition and the classical max-t-norm one, we first study the resolution of such min-product FRI system. For optimization management in the supply chain system, we further investigate a maximin programming problem subject to the min-product FRIs. An algorithm is proposed to obtain the optimal solution based on the quasi-maximal matrix and corresponding index set. To illustrate the efficiency of our proposed algorithm, we provide a simple numerical example. The obtained optimal solution reflects an optimal pricing scheme, which maximizes the minimum prices of the commodity from the suppliers.

The Impact

The aim of this paper is to understand how disruptions effect on closed-loop supply chain, and how to achieve the coordination of closed-loop supply chain under disruptions situation for the whole supply chain system. Design/methodology/approach- This paper analyzed the effect caused by the disruptions of the closed-loop supply chain from both supply and demand , and applied the established margin profits sharing contract to achieve coordination under the disruptions. Findings- From both supply side and demand side, it drew how the disruptions affect the closed-loop supply chain. When the disruptions have less effect on the forward and reverse cost of closed-loop supply chain, the impact of the closed-loop supply chain is controllable; when the disruptions have lager effect on the forward and reverse cost of closed-loop supply chain, the impact of the closed-loop supply chain is uncontrollable. Research limitations/implications- In this paper, the contract costs are ignored for zero. While in actual situation, to maintain the efficient implementation of this contract must spend considerable cost. Sometimes the cost may be too high to become hinder between manufacturers and retailers. This paper also does not make in-depth study on this issue, so it will be further study in the future. Originality/value- This paper also designed a set of differential profit sharing contract based on revenue sharing contract mechanism. The contract is easy to be managed, easy to be operated, making the closed-loop supply chain system can achieve coordination whether in steady state or under disruptions.

Revenue Model

By establishing a two-level symbiotic supply chain system consisting of one supplier and one manufacturer, we use Stackelberg method to analyze the optimal price and revenue model of supplier and manufacturer in the symbiotic supply chain under two power structures in which the supplier and manufacturer are dominant respectively, and analyze the influence of the degree of symbiosis and power structure on the model. Through comparative analysis, we find that: There is a relationship between the income level and the degree of symbiosis in the symbiotic supply chain. The change of power structure will affect the relative benefits of suppliers and manufacturers in the symbiotic supply chain. The manufacturer’s expected unit product revenue will affect the supply chain revenue when the manufacturer is dominant. Finally, the sensitivity analysis of relevant parameters is carried out through an example analysis, and the validity of the conclusion is verified. This paper has a guiding significance for the behavior of enterprises in the cogeneration supply chain.
