The AMPL modeling system has been used in hundreds of business operations worldwide. Applications are found in manufacturing, transportation, energy, finance, and many other sectors where complex decisions must be made to minimize cost or maximize efficiency.

AMPL models are built by skilled practitioners who have backgrounds in operations research, engineering fields of many kinds, diverse mathematical sciences, and business analytics. Additional assistance with AMPL application development is available from educational institutions and professional consultants.

Customer areas

Optimization is distinguished by its broad range of uses throughout the business world. Thus AMPL has been applied in numerous business areas, of which the following are representative:

Transportation Air
Production Planning: steel, automotive
Supply chain: consumer products
Finance Asset management
Investment banking
Natural resources Electric power
Gas distribution
Information technology Telecommunications
Internet services
Consulting practices Management
Industrial engineering

Case studies

Representative uses of AMPL in large-scale optimization have been reported in the following articles. All are from publications of the Institute for Operations Research and the Management Sciences (INFORMS) that describe applications of optimization approaches to problems of practical interest.
