Abstract
In this paper, we present an expansion of one of the well-known classical inventory management
models, which is the static model of inventory management without a deficit and for a single
substance, based on the neutrosophic logic, where we provide through this study a basis for dealing
with all data, whether specific or undefined in the field of inventory management, as it provides safe
environment to manage inventory without running into deficit , and give us an approximate ideal
volume of inventory. Since the ideal size is affected by the rate of demand for inventory, we present in this paper a study of the rate of demand for inventory when it is not precisely refined, and we find that the indeterminate values of the demand rate cannot be ignored, because they actually affect determining the ideal size of inventory and calculating its costs, thus affecting on the efficiency of the facility and achieve great profits for it.
