Research On Procurement Strategy For Manufacturer To Cope With Supply Chain Disruption Risk

With the further acceleration of the globalization process,the supply chain has been extended and developed in both time and space.Although global procurement is based on the expectation of cost reduction,the intricate network structure and the external environment that keeps pace with the situation exacerbate the vulnerability of the supply chain,and there is a potential risk expansion problem.Global procurement involves many links,and there are many risk nodes.Any disruption in any link will be geometrically magnified,resulting in a “bullwhip effect”,which will lead to a more normal performance level in the supply chain,and become a critical issue of global enterprise.From the perspective of the manufacturer,this paper examines the impact of supply disruption risks on foreign competitive main suppliers,domestic suppliers,and manufacturers.By assuming that there are only three levels of supply chain for mathematical modeling,it is intended to study the manufacturer’s procurement strategy due to unexpected supply disruption under the basic dual-source procurement model from the perspective of profit and domestic supplier spare parts yield.And changes in profits,but also provide corresponding recommendations for further improving supply chain risk management.This paper establishes a three-level supply chain system: competitive foreign main suppliers,uncompetitive domestic suppliers and manufacturers,as well as the terminal market,This paper selects the competitive main supplier as the risk factor,studies the single source procurement model under the supply interruption caused by the emergency or quality factors,analyzes the impact of policies on manufacturers and suppliers,and the importance of the good product rate of domestic suppliers to manufacturers in response to supply interruption.The results show that the policy has an impact on the members of the supply chain,the main supplier is indirectly affected by the policy,the manufacturer and the domestic supplier are directly affected by their own policies.Through the comparison of three cases of single and dual source procurement,in the case of dual source procurement and single source procurement from the main supplier,the manufacturer’s procurement cost shows a downward trend,and the manufacturer will choose dual source procurement to reduce the cost;in the case of single source procurement from the main supplier and single source procurement from the domestic supplier,when the yield of the domestic supplier reaches the critical value,the manufacturer will choose to choose domestic When the yield rate of domestic suppliers is less than the critical value,the manufacturer chooses to purchase from the main supplier and single source.In the case of dual source purchase and single source purchase from domestic suppliers,the yield rate of domestic suppliers is significantly different from that of manufacturers.The main supplier tends to purchase from the domestic supplier and single source Tend to double sourcing.The purchasing strategy based on the manufacturer’s profit maximization is that when the yield rate is less than the threshold value,the company purchases from the competitive main supplier in a single source,and when the yield rate is greater than the threshold value,the company purchases from the competitive main supplier in a single source.When the yield rate is less than the threshold value,the company chooses to purchase from the competitive main supplier in a single source,and when the yield rate is between the threshold value and the threshold value During this period,the manufacturer chooses to purchase from two sources.When the yield is greater than the threshold,the manufacturer chooses to purchase from a single source of domestic suppliers.
