As the automotive industry continues to thrive,market competition has become increasingly intense,and model updates and upgrades have become the norm.As upstream enterprises in the automotive industry chain,parts companies need to constantly improve their competitiveness in order to survive and develop better in the industry.Due to the strong nature of the automotive industry supply chain,many companies have been enhancing their competitiveness by optimizing supplier management.After receiving automotive development projects from the main vehicle manufacturers,parts companies need to outsource certain processes and products to secondary parts suppliers,in addition to manufacturing their own parts.The capabilities of these secondary parts suppliers are crucial for the successful completion of the projects.In addition,as different vehicle models have different requirements for project supporting products,some focus on cost control,while others focus on strict project progress control and optimizing product quality.Therefore,it is worth exploring how to identify high-quality suppliers that meet project requirements for parts companies.Based on an understanding of the current situation of supplier development and selection for a new project at parts company L,this article finds a series of problems with the existing evaluation mode,including vague and rough indicators and insufficiently scientific evaluation methods.To address these issues,this article constructs a more comprehensive set of supplier evaluation indicators and evaluation models.First,preliminary evaluation indicators are selected through literature review and consultation with industry experts,and the final evaluation indicators are determined through a questionnaire survey in the industry.Then,the determined evaluation indicators are classified according to input and output,and the weights of the input and output indicators are determined using the Analytic Hierarchy Process(AHP).Preference constraints are also introduced to meet the evaluation focus and preferences of different projects.In addition,the efficiency value of the DEA evaluation is fully sorted by introducing a virtual optimal supplier,thereby avoiding the shortcomings of the original model evaluation.Finally,taking a new project at parts company L as an example,the supplier evaluation and selection for electrocoating of collision tubes are conducted.Indicators data of six candidate suppliers are collected and inputted into the model,and the comprehensive evaluation efficiency value of the suppliers is obtained.The effectiveness and rationality of the model are verified by comparing and analyzing the evaluation efficiency results with the actual situation.This article establishes a scientific and effective method for evaluating and selecting new project suppliers from the perspective of parts companies,which not only fills the gaps in previous research in this field,but also provides new ideas for automotive parts companies to choose the best partners,with certain reference value. |
