Leadership

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 

(President & 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.

Dr. Krishna C. Jha 

(Executive Vice President & Chief Operating Officer)

Krishna’s association with Optym started in 2000 when he joined Dr. Ahuja as his Ph.D. student and later transitioned into one of the company’s first team members in 2004. Krishna has been an operations research practitioner for 15 years, focusing on the design and development of algorithms that solve real-life problems in scheduling, transportation and logistics. Krishna has led the development of several optimization and simulation software products for railroads, airlines and mining companies. His expertise in time-space network-based heuristic optimization has proven successful for solving complex problems such as train scheduling, railroad blocking and crew scheduling. Krishna has also been a key contributor in developing micro-level simulation systems for the transportation industry.

Krishna believes that decision automation is at an early stage and has endless potential to create economic and societal impact worldwide. His strength lies in collaborating with business and technical teams to come up with innovative solutions that meet business needs. He is involved at a detailed level in defining business problems, understanding data, system design, mathematical modeling, solution architecture and software delivery. Krishna also oversees Optym’s administrative operations, as well as the financial and corporate affairs of the company.

Before moving to the United States in 2000, Krishna was an industrial engineer for four years at Tata Steel, the largest private sector steel producer in India. He earned his Ph.D. in Industrial and Systems Engineering from the University of Florida, is the coauthor of nine research papers, and has won several awards at INFORMS for his research. Krishna loves reading non-fiction, music, walking and biking in his spare time.

Dr. Wei Huang 

(Vice President – System Architecture)

Huang is also one of the first Optym team members, having joined the company in 2004. He specializes in developing and solving large-scale optimization models and guiding the technical architecture of software solutions developed by Optym. Huang has over 15 years of system architecture, algorithm design and software development experience. He also has extensive expertise in data mining, data analysis and the creation of data transformation processes for large business data sets.

Huang started his academic work in computer science and engineering, particularly in the area of process automation. While working on improving the production processes of factories in China, Huang realized the need to combine computer science with mathematical optimization and did his doctoral research in supply chain management and network optimization. His academic background combines operations research and computer science skills (algorithms, data structures, databases, software engineering) and makes him ideally qualified to architect Optym’s decision automation and optimization solutions.

At Optym, Huang has led the development of several optimization products, including TrainMAX® and BlockDESIGN. As the Project Manager of the SkyMAX® airline flight scheduling system, he designed the product’s overall system architecture and played a key role in algorithm design and development. Currently, Huang is leading the effort to create a software development framework so that new decision automation solutions can be developed rapidly and maintained efficiently.

Huang earned his Ph.D. in Industrial and Systems Engineering from the University of Florida, Gainesville. He likes to read and travel.

Renzo Vaccari 

(Vice President – Airline Solutions)

Renzo has over 20 years of leadership experience designing and building airline software solutions, specifically in the areas of airline network planning and scheduling, product management and advanced decision support systems. He previously held several senior leadership roles at Sabre and GuestLogix in product management, product marketing, operations, consulting and sales.

Renzo started by working on consulting and process re-engineering engagements and provided recommendations allowing airlines to take significant advantage of technology solutions. He then led the delivery of airline solutions and consulting projects for customers globally, including systems for network planning, scheduling and revenue management. Throughout his career, he has implemented network planning and scheduling systems at a number of leading carriers all over the world including United Airlines, Delta Air Lines, LATAM, Qantas, Air France and British Airways.

At Optym, Renzo plays a key role in defining the roadmap of SkyMAX®, Optym’s new-generation flight scheduling optimization system. He is also responsible for global product management, marketing and sales for the SKY suite of airline network planning and scheduling solutions including optimization, simulation, schedule management and demand forecasting.
