Research On The Problem Of Supply Chain Disruption Management Under Asymmetric Information

In the traditional method to deal with supply chain problems, one always assumes that the information in supply chain is symmetric. While asymmetric information is common in social production and social living, and it is also true for supply chain. In the current society, various emergencies happen frequently and have an impact on production and living, and disruption management becomes the research focuses. Supply chain can be under the various influence of disruption, and more and more studies have been carried out on supply chain disruption management. This paper breaks this limitation and analyzes disruption management of supply chain with asymmetric information.In this paper, supply chain management is studied firstly without asym-metric information and disruption. Then, supply chain disruption manage-ment is studied under symmetric and asymmetric information. Supply chain is composed of a supplier and a retailer, and the demand is nonlinear. Demand and cost arc disrupted simultaneously after the production plan, and the dis-ruption information is asymmetric information for the supply chain members, i.e. the retailer knows the exact demand disruption but supplier not, and the supplier knows the exact cost disruption but retailer not. Paper analyzes sup-ply chain disruption with supplier as the principal and retailer as the principal under asymmetric information respectively. At the same time the impact on disruption management of asymmetric information is analyzed in detail. It is proved that, under asymmetric disruption information, supply chain can keep the original production plan in some cases, and the production quantity under asymmetric information equals to that under symmetric information when the demand scale varies more or the cost varies less, but the information owners will earn more profit; while the production quantity under asymmetric infor-mation is not larger than that under symmetric information when the demand scale varies less or the cost varies more and the profit of supply chain decreases with production quantity decreases. The difference of profit under symmetric and asymmetric information is analyzed as information value. And results show that asymmetric demand information have a greater influence than cost on the profit and the decision of the supply chain. The numerical examples illustrate the affection of the disruption and asymmetric information, the sig-nificance and efficiency of the proposed model with disruption, and prove that the information has important value in supply chain management.
