This new inventory level is called I. In this chapter we discuss the problem of controlling the inventory of a single item with stochastic demands over a single period. The Average Lead Time is 5 Days and the average consumption per day is 40 units. First assume that there is no initial inventory, i.e., I0 = 0. This is called ‘Economic Ordering Quantity (EOQ). ... ntroduction to Embedded Software Verification Comparison of Model Checking Tools for Information Sys. t 1): inventory level at the beginning of the tth time period.
