ILOG S.A. was an international software company purchased and incorporated into IBM announced in January, 2009. It created enterprise software products for supply chain, business rule management, visualization and optimization. The main product line for Business Rules Management Systems (BRMS) has been rebranded as IBM Operational Decision Management. Many of the related components retain the ILOG brand as a part of their name.

The software developed by the ILOG software company supports several software platforms, including COBOL, C++, C#, .NET, Java, AJAX and Adobe Flex and Flex AIR.

Founded in 1987 in Paris, France, ILOG had its main headquarters in Gentilly, France, and Sunnyvale, California. It also had main offices in Australia, China, Germany, Japan, Singapore and the United Kingdom.

Through its acquisition of CPLEX Optimization Inc. in 1997, ILOG became the owner of the CPLEX mathematical programming software, and ILOG's acquisition of LogicTools in 2007 made ILOG the owner of a line of supply chain applications. The CPLEX and other tools also had some minor rebranding under the IBM Optimization Suite of tools.
