Modeling with Xpress

This paper discusses the various options open to you, the application developer, for building and solving models using XpressMP. In particular, it assesses their relative strengths and weaknesses under these criteria of using three approaches:

• •building models in Mosel, the modeling and optimization environment and language, and deploying them using Mosel’s libraries and Xpress-Optimizer’s library.
• •building and deploying models in your application using the Xpress Builder Library BCL, together with Xpress-Optimizer’s library.
• •building and deploying models in the native language of your application and loading a complete problem instance directly into Xpress-Optimizer’s libra
