RAMIREZ, Gloria; TORNE, Marcela  y  OREJUELA-CABRERA, Juan. SCHEDULING HOPPERS FILLING OPERATIONS IN THE ANIMAL CONCENTRATED FEEDING INDUSTRY. Rev. ing. univ. Medellín [online]. 2012, vol.11, n.20, pp.165-178. ISSN 1692-3324.

This research paper develops a scheduling operations propose to ensure efficient decision making in the short and medium term of concentrated feeding industry. The proposed methodology part of generating the explosion of materials under the MRP approach and then continues whit the development of a mixed integer linear programming that coordinates the hopper filling operations so that the raw materials are opportunely in the dosing process and minimize the relevant costs in the system. The proposal was applied to a case study whit real data and showed better results than those obtained in practice by this industry.

Palabras clave : Scheduling; Mixed integer lineal programming; concentrated feeding industry; Materials requirements planning; production planning.
