linear programming modeling language

This page is basically a copy of the author's page.

Welcome to MODLER, which stands for Modeling by Object- Driven Linear Elemental Relations. It is a language for representing linear programming models, completely separate from instances defined by data realizations. It also includes representations of binary variables and logical constraints, which arise naturally in large-scale planning and operational decision support. The basic input to MODLER is a model file, and its basic output is a matrix file that is in a standard (MPS) format for most optimizers and for ANALYZE and RANDMOD. MODLER can also generate a syntax file for ANALYZE to enable automatic translation of activities and constraints into English for intelligent analysis support.

What makes MODLER different from other modeling languages?

A DOS version of MODLER, with student-size problem dimensions, is available from Kluwer Publishers. (Other platforms are available.) Other versions of MODLER, for different computing environments, are available from me. You can get more info by looking at the IMPS software news.
