A Multi-Criteria Decision Support Model for Supplier Evaluation and Selection in the Die Industry

Abstract

The die manufacturing process is a lengthy and critical phase in ensuring the successful production of the final part in compliance with customer standards and expectations, as well as facilitating a seamless transition to mass production. Supplier selection plays a crucial role in the success of this process. This study examines the activities carried out during the die manufacturing stages, their significance within the process, their impact on production, and the role of suppliers at each stage. Furthermore, it underscores the importance of supplier selection and aims to identify the most suitable suppliers using decision support systems (DSS). In this context, the evaluation process is based on data derived from supplier performance and capacity assessments, which are conducted through a scoring system by the team. Subsequently, a comparative analysis is performed using Multi-Criteria Decision Making (MCDM) methods, leading to the development of a model for establishing a decision support mechanism in supplier selection. Within this framework, factors such as time, cost, and technical requirements in die manufacturing processes are assessed through a holistic approach to enhance supplier selection and improve overall process efficiency.
