Summary
This paper describes the new version of the modeling language, named LPL (Linear Programming Language). It may be used to build, modify and document mathematical models. The LPL language has been successfully applied to generate automatically MPS input files and reports of large LP models. The available LPL compiler translates LPL programs to the input code of any LP/MIP solver, calls the solver automatically, reads the solution back to its internal representation, and the integrated Report Generator produces the user defined reports of the model. Furthermore, an Input Generator can read the data from many formats.
Zusammenfassung
Dieser Artikel beschreibt die neue Version der Modellierungssprache LPL (Linear Programming Language), die sich dazu eignet, mathematische Modelle aufzubauen, zu warten und zu dokumentieren. Die LPL-Sprache wurde zum Erstellen von MPS-InputDateien und Resultate-Tabellen größerer LP-Modelle erfolgreich eingesetzt. Der LPL-Compiler übersetzt ein LPL-Programm, das ein vollständiges Modell repräsentiert, in den Eingabecode eines LP/MIP-Lösungsprogramms, ruft den Lösungsalgorithmus auf, liest die Lösung, und ein integrierter Tabellengenerator gibt vom Benutzer definierte Resultate-Tabellen aus. Außerdem erlaubt ein Dateneingabe-Generator, die Daten in verschiedenen Formaten zu lesen.
