Modeling and simulation is the use of models as a basis for simulations to deuebp data utilized for managerial or technical decision making. A. Lead time for a stock item is normally distributed with a mean of ? days and a standard deviation at 3 days. Daily demand is distributed as follows: Daily Demand 0 1 2 3 4 Probability 0.35 0.22 0.19 0.05 0.09 Determine the lead-time demand for 25 order cycles. [Round off lead time to the closest integer during the simiation and, if a negative value results, Give it a lead time of Elem}
