Analysis of interactions of criteria and sub-criteria for the selection of supplier in the built-in-order supply chain environment

The supplier decision-making problem is complicated by several criteria and sub-criteria. The criteria and sub-criteria used may vary across different product categories and situations. The aim of this article is to analyse the interaction of criteria and sub-criteria that are used to select the supplier for the built-in-order supply chain environment in the original equipment manufacturing company. The paper aims to demonstrate how the model can help in solving such decisions in practice. This paper uses the Interpretive Structural Modeling (ISM) methodology to understand the interactions among the criteria, which influences the supplier selection. The effectiveness of the ISM model is illustrated using a case study taken in a company in the southern part of India.
