ILOG CPLEX is not a modeling language, nor is it an integrated development environment (IDE). You can completely model and solve your optimization problems with ILOG CPLEX; however, the features it provides do not offer the interactive facilities of a modeling system in an integrated development environment. If you are looking for such a system, consider ILOG OPL and ILOG ODM.

ILOG OPL Development Studio is a powerful system for rapid development and deployment of optimization applications. ILOG OPL Development Studio (or OPL for short) consists of:

ILOG OPL Development Studio is integrated with a companion product called ILOG Optimization Decision Manager (ODM). ODM is both a tool for application development and a runtime environment. The combined product is a complete solution for the development and deployment of optimization-based planning and scheduling applications. Applications built with ODM allow users to adjust assumptions, operating constraints, and goals for planning and scheduling resources. End users of ODM also see the results in familiar business terminology. ODM applications support extensive what-if analysis and scenario comparison features "out of the box."
