Dimensionamento do estoque de segurança e do ponto de ressuprimento de produtos de demanda independente: um estudo de caso em uma indústria de bebidas no estado do Ceará

Abstract

This paper is related to the application of a study of inventory management, with the scaling of safety stocks and resupply point demand of independent demand products in a medium-sized beverage industry in the state of Ceará, Brazil. Many companies have difficulty obtaining greater productivity gains due to limitations in inventory management. One way to solve this problem is the adoption of a policy aimed at reducing the inventory level without increasing the cost of lost sales. Thus, a study to determine the levels of safety stock and resupply point at the same time that meets the demand, keep the costs of holding inventory as low as possible is necessary. Currently, managers are very concerned about the unmet customer order and also with the high volume of unnecessary stock of some produced itens. The managers’s expectation is to eliminate these obstacles without making investments neither in the production process nor in the area for the storage of finished products. In this sense, we seek to determine the safety stock and resupply point using the tools commonly used in the literature, which involves statistical analysis of demand behavior. The results show that the demand can be met with smaller amounts of stored products and a routine can be established with the replacement of finished products that increase the productivity of the organization.
