Features and Benefits

IBM ILOG CPLEX Optimization Studio supports rapid development and deployment of analytical decision support applications based on optimization technology with debugging, testing, tuning and application generation capabilities

Click to enlargeIBM ILOG CPLEX Optimization Studio provides the fastest way to build efficient optimization models and state-of-the-art applications for the full range of planning and scheduling problems. The Optimization Programming Language (OPL) provides a natural representation of optimization models, requiring far less effort than general-purpose programming languages. The Integrated Development Environment (IDE) makes it easy to evaluate different modeling approaches and to integrate external data. With its built-in development tools, it supports the entire model development process.

In addition to accessing the IBM ILOG CPLEX Optimizers for mathematical programming and constraint programming through the OPL language and IDE, IBM ILOG CPLEX Optimization Studio also provides access through the ILOG Concert Technology API in C++, Java, or Microsoft .NET, or through the CPLEX Callable Library. Alternatively, IBM ILOG ODM Enterprise embeds and integrates the modules of IBM ILOG CPLEX Optimization Studio to generate state-of-the-art enterprise decision support applications with what-if scenario comparison capabilities and tabular and graphic data views.

IBM ILOG CPLEX Optimization Studio Features

The IBM ILOG CPLEX Optimization Studio delivers the tools to create both well-tested and finely tuned optimization models and interactive analytical decision-support applications. Advanced features help users develop complete optimization applicationswithout requiring detailed knowledge of computer programming.

• IBM ILOG CPLEX Optimization Studio combines and simplifies IBMs product offerings for optimization application development, solving, and deployment. It offers in a single package, all the functionality that was previously available among an array of product and component configurations, making all tools and technologies available during prototyping and development.
• Natural representation of optimization problems
  Compared to conventional programming languages, Optimization Programming Language (OPL) represents optimization problems descriptively, simplifying model development. OPL provides a rich toolkit to address a variety of problem types, allowing comparisons of alternative and hybrid solution methodologies.
• Support for two optimization technologies
  The IBM ILOG CPLEX Optimization Studio is designed to support IBM ILOG CPLEX Optimizer the world's leading mathematical programming optimization engine, as well as IBM ILOG CPLEX CP Optimizer, our state-of-the-art constraint programming engine for solving sequencing, resource allocation and timetabling problems that are difficult or impossible to solve with mathematical programming techniques. IBM ILOG CPLEX Optimization Studio allows users to develop single models in either technology or multi-model solutions that use either or both technologies. Interval-based scheduling support is available. It is based on the "model and run" concept: Robust search algorithms and automatic search parameter settings allow users to concentrate on modeling without being worried about the search itself.
• A full-featured scripting language
  OPL Script is a full-featured JavaScript language for data pre-processing, solution post-processing, and algorithmic flow control. OPL Script also makes it easy to solve complex problems by combining or sequencing related models.
• Integrated application programming interfaces (APIs)
  Models created by IBM ILOG CPLEX Optimization Studio can be easily integrated into external applications written in Java, C++ or .NET, without having to rewrite the model in other programming languages.
• Connections to spreadsheets and relational databases
  IBM ILOG CPLEX Optimization Studio can import data and export solutions to databases or spreadsheets. A clean separation of the model from the data makes it easy to switch between test data files and production data sources.
• An interactive development environment
  The IBM ILOG CPLEX Optimization Studio integrated development environment (IDE) supports model development, data and parameter combinations testing, and results reviews. The implementation of IBM ILOG CPLEX Optimization Studio's "Run Configuration" concept allows users to evaluate different modeling approaches to a problem with the same data, and/or different data sets with a given model, and to experiment with different algorithmic control parameter settings that combine models, data and parameter settings into run configurations.
• Conflict detection/display and recommended conflict resolution
  Detect and display conflicting constraints in infeasible models using CPLEX Optimizers conflict refiner. Relax constraints based on user defined priorities.
• Execution tracing and profiling
  Full access to CPLEX Optimizer and CP Optimizer log files enables tracking the solve progress. Use profiler to understand use of memory and time by different phases of the execution process.
• Automatic performance tuning
  Use the IBM ILOG CPLEX Optimizer tuning tool to automatically tune engine performance on mathematical programming models.
• Automatic application generation
  IBM ILOG CPLEX Optimization Studio and IBM ILOG ODM Enterprise have made it possible to automatically generate an IBM ILOG ODM Enterprise application from the structure of an OPL model. A simple wizard-guided step provides the initial application. OPL data structures are automatically mapped to data tables in IBM ILOG ODM Enterprise, decision variables and solution metrics are mapped to solution views, and objective functions are mapped to IBM ILOG ODM Enterprise's interactive business goals. Constraints marked as relaxable in the OPL model are exposed to the end user by name and priority, allowing relaxations and trade-offs based on business importance.
• Latest version
  IBM ILOG CPLEX Optimization Studio 12.3 offers access to predictive analytics tools by providing a connector to IBM SPSS Modeler. The ability to execute Modeler streams directly from CPLEX Studio makes an integrated modeling environment for prescriptive and predictive analytics available to professionals using multiple advanced techniques. CPLEX Studio also extends its reach to developers using Linux on Intel compatible processors by making available the IDE on this platform. The CPLEX Optimizers offer significant performance gains both for mathematical- and constraint-programming. Additional enhancements include support for solving very large models (> 2 billion non-zero elements), capabilities to solve quadratic programs with non-convex objective functions, and capabilities to solve scheduling problems with non-convex objectives and constraint programs with multiple objective functions.
