Optym’s leaders bring decades of experience in transportation, logistics and scheduling, and combine their real-world knowledge with their expertise in operations research, computer science and engineering.

Dr. Ravindra K. Ahuja 

Founder & CEO

Ravi is the founder of Optym and an academician turned entrepreneur. In an academic career spanning over 30 years, he has taught at the Indian Institute of Technology, Kanpur and the Sloan School of Management at MIT, and he is currently a professor at the University of Florida, Gainesville. He is the coauthor of three textbooks including Network Flows: Theory, Algorithms and Applications (a leading textbook used at hundreds of universities worldwide) and over 100 research papers in optimization, mathematical modeling and algorithms. He has contributed significantly to the theory and application of network optimization, and his research papers and books are widely cited. He has received several prestigious awards for his books and research papers.

While doing research for transportation and logistics companies, Ravi discovered a big disconnect between academics and industry practice. He observed that advances taking place in optimization and computer science weren’t benefitting the transportation and logistics industry, which continued to use rudimentary techniques. Determined to change that, he founded Innovative Scheduling (which later changed into Optym) to bring the latest advances from theory to business. He continues to play a key role in Optym’s evolution from a local start-up to a global provider for decision automation and optimization solutions. He is a hands-on person who works with colleagues to solve business problems and design algorithms and user interfaces. He also performs consulting work and oversees new product development, partnership opportunities and business development initiatives.

Ravi earned his Ph.D. in Industrial and Management Engineering from the Indian Institute of Technology (IIT), Kanpur. He enjoys playing tennis, traveling and seeing the world, and meditation.
