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. WebThe handbook contains papers which explore both the deterministic and the stochastic EOQ-model based problems and applications. It is organized into three parts: Part I presents three papers that provide an …
