ILOG
software company that makes products including JRules
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.

Why this record matters
The phrase “software company that makes products including JRules” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 24, 2026. The linked authority identifier is Q2011386. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2009, 1987, 1997 and 2007.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
