The collaborative decision of profit distribution in retail supply chain under emergency

Aiming at the profit optimization distribution problem of retail supply chain under emergencies, the retail price and revenue sharing proportion are set as the floating parameters. The profit distribution multi-objective programming model of retail supply chain is created based on revenue sharing contract under the emergency. Cooperation intentions are concluded by the dynamic negotiation. This paper presents a collaborative decision algorithm of retail supply chain profit distribution based on multi-objective symbiotic co-evolutionary genetic algorithm. The multi-objective evolutionary optimization problems of retail supply chain are well studied under emergency, by which the intelligence and precision of multi-objective collaborative decision-making are improved. The numerical experiment results show that the profit distribution multi-objective programming model of retail supply chain under emergency makes profits into balance for both sides and the entire supply chain profit loss into minimization. The feasibility of the collaborative? decision algorithm for retail supply chain profit distribution is verified under emergency.
