MATHEMATICAL PROCEDURE, ORIENTED THE SIMULATION IN FLEXSIM, USING A PLANNING TEACHING SYSTEM MATERIALS REQUIREMENTS (MRP)

Abstract

This paper presents a teaching system for Higher Education Institutions in careers such as logistics, supply chain, internal
logistics and related fields, through the understanding of mathematical procedures oriented to simulation.
Presenting a case study of material requirements planning (MRP) that provides a production and supply schedule, according to
the sales forecasts of a Distribution Centre (CEDIS): The production standards and delivery times of the suppliers, which
respond to the What, how much and When to supply. (Velasco Flores, 2017): MRP is a set of techniques that uses bill of materials data, inventory data and the master production plan to calculate material requirements. It suggests releasing material replenishment orders and rescheduling open orders, based on the time lag. (APICS,2019): The MRP I mathematical procedure presented in this research is based on two fundamental aspects:
1. It refers to finished products.
2. This system is carried out according to the needs of each item (independent demands and product structure):
MRP I is based on the calculation of the net needs of the articles and components, introducing a factor not considered in the
traditional methods of stock management, which ultimately leads to modulate the time, with due planning with respect to its use,
to subsequently simulate it in a software.
