Problems solved by technology

In terms of methods, the traditional particle swarm optimization algorithm has problems such as too long search time and easy to fall into local optimal solutions. We propose an intelligent algorithm combined with dynamic relaxation factors to realize decision-making and scheduling optimization of sustainable supply chains.

Abstract

The invention discloses a site selection and distribution method of sustainable supply chain based on a dynamic relaxation intelligent algorithm. The method comprises the steps: 1, building a three-level structure sustainable supply chain model integrated with supply chain site selection and quantity distribution based on a comprehensive weighted score and by adopting the minimization of production cost, carbon transaction cost and pollution discharge cost as an optimization target; 2, converting supply chain site selection and quantity distribution into a vector form, and performing iterativeupdating operation on a solution population by using a dynamic relaxation swarm intelligence algorithm and combining a fitness function value with a dynamic relaxation factor until an optimal approximate solution of a target function is obtained, thereby obtaining the site selection decision and quantity allocation scheme of the sustainable supply chain network, and providing a high-quality and high-efficiency solution for designing a complex sustainable supply chain.

Description

technical field [0001] The invention belongs to the technical field of sustainable supply chain site selection and collaborative scheduling, and in particular relates to a sustainable supply chain site selection and allocation method based on a dynamic relaxation intelligent algorithm. Background technique [0002] The supply chain is a network composed of suppliers, producers, and customers. The purpose is to address the location and distribution of multiple factories and multiple customers in the sustainable supply chain, and process raw materials from suppliers in the sustainable supply chain and provide them to Manufacturers, in the process of producing raw materials as products and distributing them to customers, by optimizing the site selection decision and quantity allocation of the supply chain, and comprehensively considering environmental factors (carbon emissions, sewage discharges), the production process in each link is effectively reduced. The impact of carbon ...
