Evaluation of Indian Railway’s Supply Chain Parameters for Improved Sustainability Under Industry 4.0 Transformation: An Application of AHP and TOPSIS

Indian Railways (IR) is India's major public transportation system and one of the world's largest and busiest rail networks. The Indian government is in charge of owning and running it. This paper presents an alternative approach to measuring the overall operational performance of the Indian Railway supply chain. The operation of Indian railways from a supply chain perspective needs to be analyzed to improve customer service and inventory management. Industry 4. 0 is used for the easy processing of individual transportation components efficiently and safely. The study is useful for the Indian Railways because it enables the classification of various issues related to government procurement. A supply chain model is proposed to assess service expectations and quality. Various issues (such as the integration system, financial behavior, and management perspective) related to supply chain management have been identified, and various factors affecting availability, railway service quality, and reliability have been analyzed for managing its supply chain. The Analytical Hierarchy Process (AHP) and TOPSIS have been used to examine inventory-related difficulties and make recommendations for the public procurement environment. The result of the AHP method showed that Model 1 (Integration System) has the highest MaxCweight of 0. 5348, followed by Model 2 (Financial Behavior, 0. 381695) and Model 3 (Management Perspective, 0. 399443). The consistency ratio (CR) for all three models was also less than 0. 1. Further, the TOPSIS method was used to validate the accuracy of AHP results and found that the model is significant. This result will help the decision-makers at Indian Railways design an assessment and relationship management model that will help them make procurement the driving force behind their supply chain. As per COP27, Industry 4. 0 will help to achieve net zero emissions. The net carbon emissions will be reduced to zero, which will result in a clean environment. To improve sustainability within the framework of the Industry 4. 0 transition, the research aimed to evaluate the Indian Railway's supply chain metrics. Analytical Hierarchy Process (AHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) are methodologies used in this assessment.
