-The purpose of this paper is to provide a method to solve the scheduling problem of a textile machine in a clothing workshop. The scheduling of the production in the textile sector clothing was the goal of many studies. The obvious interest of the mathematical approach is to guarantee the optimal solution. Unfortunately, for the real problems in the textile industry, these approaches became very complex. Thereafter, these procedures can be associated with heuristic methods or algorithms of local research; the purpose is to accelerate convergence towards the optimal result. In our work, we use optimization by the ants colonies to solve scheduling problems of the production in the textile clothing companies.
