Independent Verification and Validation of an Industrial Simulation Model

The independent verification and validation (IV&V) of simulation models is largely restricted to applications in the military and public policy domains. There is little evidence of IV&V for industrial simulation models. This is largely because industrial simulations are normally of a much smaller scale and do not warrant a full IV&V. A procedure for IV&V of industrial simulation models is described that provides a viable alternative where the cost and time of IV&V must be contained. The procedure consists of the following activities: structured walkthrough, review of model assumptions, code examination, review of verification procedures, replications analysis, review of static analysis, review of output reporting, and investigation of results and experimentation. The IV&V of a Sellafield Limited supply chain model is described.
