Problems solved by technology
The sustainable supply chain design takes more environmental and social factors into account to ensure that an efficient and comprehensive technical solution is finally obtained. Therefore, the design of a sustainable supply chain network needs to take into account the number of participants at all levels, the location, and the relationship between each node. Logistics planning also considers the corresponding environmental factors and social factors. At present, there is no effective design method for this kind of supply chain to solve the problem of long solution time and large deviation between the solution result and the actual situation due to many limiting factors in the supply chain.

Embodiment Construction
[0121] The invention will be further described below in conjunction with the accompanying drawings and specific implementation examples. Use the directed graph G= to simulate a four-level sustainable supply chain network, where the vertex set V contains four subsets, which are supplier candidate set, manufacturer candidate set, distributor candidate set, and customer candidate set. Each vertex V in the set is a candidate node of one of the above types. The supply chain describes that only nodes in adjacent layers can be connected to each other, and its goal is to meet customer needs while considering environmental factors, social factors, and determine each edge according to production limits, storage limits, and continuity limits. (v i , v j ) to design the location, production arrangement and logistics planning of the sustainable supply chain.

The invention provides a sustainable supply chain design method based on a graph network, and the method comprises the steps: firstly building a sustainable supply chain mathematical model based on suppliers, manufacturers and distributors, and then designing an undirected acyclic connected graph structure according to the sustainable supply chain mathematical model, and finally, designing an algorithm to carry out optimal value solving on site selection, production arrangement and logistics planning of the sustainable supply chain. According to the invention, the enterprise information transparency index, pollutant emission and transfer data and enterprise environment protection data are integrated; the integration target of the manufacturing industry innovative supply chain is provided through a method of integrating and unifying a plurality of targets, optimal solution is carried out on site selection, production arrangement and logistics planning of the sustainable supply chain by utilizing a genetic algorithm on the basis, and an optimization solution scheme is provided for the large-scale manufacturing industry supply chain.
Description
technical field [0001] The invention relates to the technical field of supply chain network design, in particular to a graph network-based sustainable supply chain design method. Background technique [0002] The manufacturing supply chain is a functional network chain structure that connects suppliers, manufacturers, distributors, and final customers as a whole. It is the entire process from the purchase of raw materials to production to distribution around the core enterprise. Sustainable supply chain design takes more environmental and social factors into account to ensure that an efficient and comprehensive technical solution is finally obtained. Therefore, designing a sustainable supply chain network needs to take into account the number of participants at all levels, the location, and the relationship between each node. Logistics planning also takes into account the corresponding environmental and social factors. At present, there is no effective design method for this...
