Modelisation of the maintenance-production couple by a graph of scheduling

The problem of scheduling, both maintenance and production, was a work of many articles. The algorithms of genetics, ant, and multi-agent give solutions approaches with this problem. This paper modeled the problem in a simple and concrete way, pushing the researchers to propose a graph connecting the maintenance and the production with weighting realities. To develop the quality and validity of the model, a statistical tool is used for the calculation of the factors of variances, in order to improve the output of the production.
