AMPL > >About Us


AMPL Optimization Inc. is dedicated to helping you meet the challenges of building, maintaining, and deploying complex, custom-designed optimal decision models. The AMPL modeling language and system have been adopted by companies and organizations worldwide to bring optimization to a broad range of business and research applications, and to support teaching in the many fields that employ optimization as a modeling paradigm.


Working at Bell Laboratories, Robert Fourer, David M. Gay, and Brian W. Kernighan developed AMPL to help people communicate optimization models to computer systems, by leveraging the power and convenience of familiar algebraic formulations. Following its general release, AMPL’s reputation grew rapidly, supporting new implementations of traditional optimization models and motivating applications in new areas. The book AMPL: A Modeling Language for Mathematical Programming became the best-recognized introduction to practical algebraic modeling.

Since 2010, we have dedicated our professional efforts to providing the best optimization tools to advanced professionals throughout business, engineering, science, and education. The response has been enthusiastic, driving steadily increasing demand and establishing AMPL as a fundamental tool in the practice of analytics.

  • William M. Wells, Chief Executive Officer, joined AMPL Optimization in 2010 as executive vice president for business development. He has been a member of executive teams as a Senior Vice President at Talus Solutions, a revenue management company, and Quovera, a business consulting and technology integration firm, with responsibility for operations and customer relationships.

  • Robert Fourer, founder and President, was Professor of Industrial Engineering and Management Sciences at Northwestern University for 33 years. Since 2012 he has devoted full time to AMPL Optimization. He is the author of numerous articles on optimization modeling and has served as Area Editor of three leading journals in this area. His work has been recognized by the Beale-Orchard-Hays Prize for computational optimization and by election as a Fellow of INFORMS.

  • David M. Gay, founder and director, has had a distinguished research career at M.I.T., Bell Laboratories, and Sandia National Laboratories. Since 2010 he has devoted full time to AMPL Optimization. His numerous investigations in nonlinear optimization and modeling systems have led to recognition as a Highly Cited Researcher in mathematical and in computer science.

  • Brian W. Kernighan, founder and director, is Professor of Computer Science at Princeton University. He is internationally known for his work at Bell Laboratories on numerous languages and systems including C and Unix, and for books in computer science including most recently D is for Digital. In 2002 he was elected a member of the U.S. National Academic of Engineering.
