LP modelling
L’objectif est d’apprendre à modéliser un problème décrit en langage naturel en un Programme Linéaire.
- Know the definitions associated to LP: feasible solution, optimal solution, feasible region…
  
  Know the elements that form an LP: decision variables, objective function, constraints
  
  Be able to model an LP from a simple problem described in natural language
- Linear Programming Modelling (course and corrected exercices, in French) Урок
- La programmation linéaire propose un cadre de modélisation pour des problèmes d'optimisation sous contraintes et des outils pour trouver des solutions optimales. Cet outil fondamental de la recherche opérationnelle a émergé lors de la seconde guerre mondiale.
  
  Cette leçon présente ce qu'est la programmation linéaire, un exemple de modélisation (concombre et oignons), les différentes représentations d'un programme linéaire et le vocabulaire associé.
  
  Une série de 3 vidéos présente comment modéliser un problème décrit en langage naturel en programme linéaire et 3 exemples types :
  
  vidéo Introduction et exercice introductif (12 minutes)
  
  vidéo exercice 1 (alliage) (9 minutes)
  
  vidéo exercice 2 (gestion d'un réseau d'eau) (12 minutes)

- The modeling labs allow you to practice modeling. Feel free to do as many as you can. The first step before doing a modeling lab is to write the model on paper to separate the difficulty of modeling from possible technical or syntax problems.
  
  The labs are written in IBM's OPL (Optimization Programming Language). The OPL User Guide 1 image describes an example of a linear program in OPL with the necessary syntax as well as how to write a model in a modeling lab. The Playing with the Example lab of the OPL User Guide 1 allows you to manipulate your first pre-filled OPL lab. The Short OPL Tutorial manual allows you to learn more about the OPL modeling language. You can model and solve your own PL problems in the Sandbox.
