Abstract: This document generally describes simulating warehouse automation designs and evaluating the results of such simulations to optimize automated warehouse designs. Warehouse automation can be simulated, for example, to determine an optimal warehouse automation design given a variety of parameters that are specific to the warehouse, such as the expected customer inventory demands over time, the layout of the warehouse, and/or the specific automation features (e.g., machines) that are possible within the warehouse. Such warehouse simulations can be repeatedly run and warehouse automation designs can be modified to identify an optimal warehouse automation design that will, for example, maximize the efficiency of the warehouse by minimizing pallet place and pull times, minimizing truck load/unload times, and minimizing/eliminating failures during which the warehouse is not able to meet threshold performance metrics.
