WebModels that allow for a fixed lead time can be handled relatively easily by transforming the problem to make the inventory position the state variable. The inventory position is the sum of on-hand inventory and orders placed but not received (Bather [2]). Stochastic lead times are however significantly more challenging and interesting.
