Allows users to simulate multi-stage inventory systems.  Stages may be reliable or subject to disruptions.  Despite its name, BaseStockSim can accommodate several types of inventory policies, including base-stock, (R, Q), and (s, S) policies, as well as a modified (R, Q) policy in which the value of Q is chosen dynamically based on the values of the state variables.  For base-stock policies, base-stock levels are set by the user explicitly but may also be interpreted using the “committed service time” notion of so-called guaranteed-service models (see, e.g., Simpson 1958, Kimball 1988, Graves and Willems 2000, 2003).  After running the simulation, you can view an “instant replay” to examine the inventory and backorder levels at each stage and watch the system evolve over time.  BaseStockSim also has a feature for performing batch runs in order to test many values of the parameters in sequence.

For more information, see the User Guide, which is distributed with the software.
