assumed to be lost in the retailers and orders incurred stock out in the warehouse, are backordered. We approximate demand in the warehouse as poisson together with its mean rate. We then compare the approximation results with simulation for the average waiting time of the orders in the warehouse as the criteria for performance of the approximation. Less error of the mentioned criteria means that our approximation of poisson demand in the warehouse works better.
