Production & Operations Management

Prof. Rajeev R. Tripathi explains how IIMB empowers PhD students to grow into independent and competent researchers. He talks about current research in strategic sourcing and procurement decision in supply chain, behavioural operations, sustainable operations, agricultural supply chain management and more.

The auto industry races toward sustainability, making manufacturers face a strategic dilemma—pursue radical innovations like EVs or adopt incremental solutions like hybrid and flex-fuel technologies. Each choice carries trade-offs in cost, emissions, and consumer adoption.
Production and Operations Management area PhD scholar Satyajit Roy unpacks these decisions, incorporating the moderating role of conventional vehicle ownership, resale value and the emission levels of green technologies to help the automaker and policy maker arrive at a better decision.

Karthik Ramaswamy’s doctoral research investigates how firms balance environmental and social sustainability in supply chains? Karthik employs game-theoretic models to understand how informal recyclers disrupt sustainable waste management; why transparency laws fail under state-imposed constraints; and how tariffs and subsidies alter sourcing strategies, ultimately slowing the global adoption of clean tech.

The key focus area of my research is to analyze the impact of supplier innovativeness in a supply chain network on the firm’s innovation, and how different types of buyer-supplier relationships impact the innovation of the firm. I use different empirical and analytical modelling tools to generate insights into how global supply chains work, and how firms need to design their supply base portfolio
