Modelo de inventario multiartículo con demandas potenciales y tasas de producción dependientes delas demandas

Abstract

The control and management of inventories represents an important part in the commercial distributionof products and, more specifically, in the supply chain. The inventory management models allow us toplan, maintain and control, efficiently and effectively, the supply of goods and raw materials forproduction, including scheduling orders, storage, maintenance, and sale of items to meet the demandof the clients. An adequate control of the inventory must be one of the main points to take into accountin the business or industrial activity, since this will help to cover the future demand of the consumers,trying that the total cost related to the maintenance and the management of the inventory be the smallestpossible.In this paper we will study an inventory system for multiple items that are replenished together everycertain period of time. Each item has a different production/replenishment rate, which is dependent onits demand ratio. Demands of the items follow potential patterns. The evolution of the inventory levelsof the products is analyzed and the optimal inventory management policy is studied, determining theoptimal inventory cycle, the economic production quantity for each article and the total cost related toinventory management.
