Research On Supply Disruption Replying:Divided Customers Perspective

Along with the prevalence of production modes like JIT,lean production and flexible production and business strategies like global sourcing and business outsourcing,supply chain is becoming more and more complex,and more vulnerable to disruption.In recent years,due to the increasing frequency of emergencies such as disasters,strikes,economic crisis and political events,the frequency of supply disruption in supply chain is also increasing.And as we can see from the impact of emergencies,the loss caused by supply disruption is increasing.Practice shows that effective replying measures can not only reduce the loss of enterprise,but also may make the enterprise expand market share by using the emergency.The thesis studied the supply chain system which consisted of a supplier,a manufacturer and final customers.Our research supposes that customers are divided into two groups because of different value they created.In face of supply disruption risk,the manufacturer can choose safety inventory,strategic reserves and backup supplier for replying.Firstly,the thesis introduced the concept and reason of supply disruption,the meaning and standard of divided customers,and the replying measures to supply disruption.Secondly,the thesis studied the optimal strategy of the manufacturer in single-cycle disruption and multi-cycle disruption.In the study of replying measures in single-cycle disruption,the thesis built single-cycle-single-supplier model and single-cycle-double-supplier model.Based on the actual cost of some enterprises,the thesis did numerical experiments by using Lingo11 software,and did sensitivity analysis of relevant cost factors,and then put forward management insights.In the study of replying measures in multi-cycle disruption,the thesis built multi-cycle-single-supplier model and multi-cycle-double-supplier model.The thesis also did numerical experiments by using Lingo11 software,and did sensitivity analysis of relevant cost factors,and then put forward management insights.Finally,the conclusion was drawn through the analysis of the optimal measures in single-cycle disruption and multi-cycle disruption and the results of sensitivity analysis: the optimal strategy of double suppliers would have the lowest cost;the disruption probability of major supplier,especially disruption recovery capability,had a great influence on the choice of replying strategy;the inventory cost and strategic reserve cost of manufacturer per unit,the shortagemanufacturer and the choice of the optimal strategy;the proportion of key customers' needs would affect the total cost of the manufacturer;the fixed cost of strategic reserve and backup supplier would have less effect on the total cost and optimal strategy of the manufacturer.
