Abstract
Introduction. This research addresses the problem of internal materials supply operations in a pre-milling
type concentrate food plant. The required amount of raw materials for production in the internal supply chain
is determined by minimizing the total relevant operational cost, made up by the setup cost and the stock
maintenance cost, which maximizes efficiency of the resources used in the process. This study takes into account
such factors as capacity of the hoppers, the time-dependent setup sequence, routes of supply hoppers, filling
rates and supply times, based on a model of mixed-integer linear programming. Objective: Provide a strategy
that allows efficient use of resources in the production process, subjected to the demand of materials from the
material requirements planning (MRP) of the company under study. Materials and methods. The short-term
multi-period model defines the scheduling of elevators and conveyors for each time period, and the amount
of raw materials that is sent to each hopper and bins. Results. This research determines the amount of initial
stock required to operate, as well as the operations strategy that the company under study must follow, so
that it meets the demand for raw materials, making efficient use of the resources used in the production
process. Conclusion. In the analysis of results and presentation of scenarios, the most representative cost, the one related to stock maintenance, could be observed.
Since this is a critical factor for companies belonging
to this sector, we present an innovative proposal,
both in practice and in the literature, to contribute
to minimizing the total setup cost and the cost of
maintenance of raw material stock in hoppers through
a rational use of resources.
