| As more and more companies consider supply chain management capabilities as an important part of their market competitiveness,the importance that companies attach to the construction and management of their supply chains is also increasing.In recent years,the world is in a complex and volatile environment,with trade frictions,geopolitical disputes and other risk events affecting the operation of supply chains occurring from time to time.In particular,since the outbreak of the new epidemic,its impact has spread to all areas of the world,affecting the global supply chain system and the cornerstone of the global manufacturing industry,casting a shadow over the global economic recovery and supply chain operations.As supply risk is a potential source of supply chain disruption,the question of what strategies supply chains should adopt to deal with possible supply risk in the context of supply risk,in order to maintain the sustainability of business and the stability of supply chain revenue,is an urgent issue to be addressed.This study uses the EMD method to quantify the impact of the supply risk environment on automotive manufacturing company B and to analyse the problems of the company.Based on this,a supply risk model is constructed to investigate the impact of the secondary ordering strategy on the expected revenue and order quantity of automobile manufacturer B under different supply structures of single source and multiple sources.The study found that,in most cases,a more diversified supply chain structure could lead to higher expected revenue than a single supply chain,and that automotive manufacturer B should establish a supply chain risk control management system based on supplier data,and use data analysis and model simulation to provide a basis and reference for decision-making.In addition,the company should insist on the open reform of the vertical supply chain,and further adjust the current supply chain contract model and implement a secondary ordering strategy to pursue higher expected returns while mitigating the impact of supply risk on the supply chain.In addition,B automobile manufacturers should strengthen the management of product price and raw material cost performance,continuously pay attention to the market situation,and develop new markets for their products as much as possible to empower their products.The results of this study are based on realistic data and provide targeted suggestions for the ordering strategy of automobile manufacturing enterprise B under supply risk,and provide a reference basis for the formulation of supply chain strategies in the automobile manufacturing industry under supply risk through the analysis of quantitative results of model simulation,in order to achieve the healthy and stable development of the supply chain of automobile enterprises. |
