service supply chain using fuzzy TOPSIS method. Health Services and Outcomes Research Methodology, 1-27.

This paper aims to apply a multi-criteria decision-making (MCDM) framework to evaluate the environmental
performance of the medical service supply chain using a case study in India. An application of MCDM method, the

fuzzy TOPSIS (Technique for order of preference by similarity to ideal solution) model, is used for Medical Support
Service Provide firms (MSSPF) environmental performance evaluation. We require multiple and conflicting criteria to

fix real-life decision-making challenges, which in turn led to the inception of (MCDM). However, MCDM is contracted
with various contradictory requirements in which the knowledge of decision-makers is generally vague and thereby

more challenging. In this situation, inclusions of fuzzy set theory in MCDM Methods would be good to solve the MCDM
problem. In this study, the authors used a fuzzy TOPSIS MCDM model to solve the evaluation framework. Data were

collected from the experts from the MSSPF about the more perfect criteria to assess environmental performance
using a questionnaire. Case assesses the environmental performance, based on defined criteria, of three MSSPF by

the experts. Fuzzy TOPSIS Method ranks three MSSPF according to environmental performance in the following order:
Firm B, Firm A and Firm C. The result suggested that ‘Firm B’ performed superior environmental performance followed

by ‘Firm A’ and ‘Firm C’. This evaluation framework will help MSSPF to identify potential areas of further improvement in
Environmental performance, and thereby creates strategies to overcome and formulate new innovations. Notably,

this is one of the few studies to have used this method to gauge the environmental performance of the medical
service supply chain in India.
