Model construction and comprehensive evaluation of quality infrastructure capability building model in the equipment manufacturing industry

Quality Infrastructure serves as a crucial foundation for the high-quality development of the equipment manufacturing industry, encompassing numerous factors and constituting a complex systems engineering project. Addressing the current challenges of incomplete elements and insufficient integration in the industry’s quality infrastructure construction, this paper focuses on the construction needs of the equipment manufacturing industry, it clarifies the constituent elements of the industry’s quality infrastructure and constructs an overall framework for capability building based on the “Regulatory System–Management System–Technical System.” To tackle the problems of lacking evaluation indicators and strong subjectivity in evaluating quality infrastructure capability, a quality infrastructure capability evaluation model and indicator system for the equipment manufacturing industry are proposed from the dimensions of industry influence, institutional construction, resource supply, and equipment quality assurance. Based on fuzzy theory and the VIKOR method, a comprehensive evaluation method for quality infrastructure capability in the equipment manufacturing industry is proposed. Ultimately, an application in a specific aviation equipment manufacturing sector is undertaken to validate the effectiveness of the proposed method.
