Mosel Module Repository

By implementing their own libraries for Mosel users can add new functionality to the Mosel language and make it evolve according to their needs. User-written libraries may take the form of packages or modules.

Packages are libraries written directly in the Mosel language with a similar structure as Mosel models. They are ideally suited to give access to model parts (e.g., reformulations) or algorithms written in Mosel that you wish to distribute without disclosing their contents, for the development of your personal Mosel 'tool box', or even to implement add-ons to Mosel modules.

Via Mosel's Native Interface users may define their own modules that are treated just like the software components of the Mosel distribution. Typical uses for modules include the implementation of problem-specific data handling, or connections to external solvers or solution algorithms.

This page provides a distribution point for 3rd party packages and modules. If you have a package or module that you would like included then please contact .

Xpress-SP (mmsp module)     Xpress-SP is a Stochastic Programming tool for solving optimization problems involving uncertainty. Xpress-SP can be used to model and solve problems occuring in Supply Chain Management, Energy, Finance, Transportation, etc., by building uncertainty into the optimization problem in order to hedge against future variability. By assimilating uncertainty into the optimization process, Xpress-SP enables superior management of resources by eliminating the overhead costs of conservative planning, reducing penalties for unmet targets, and achieving higher service levels and profits. For further information on Stochastic programming and Xpress-SP please see the following links:-  Basics of Stochastic programming  Stochastic programming with Xpress-SP  Overview of Stochastic Programming Applications  Modeling and solving Stochastic programming problems in supply chain management using Xpress-MP (abstract ) Usage of this module is governed by the Xpress-SP OPEN License Agreement as included in the packages.
