View the Complete Application at the US Patent & Trademark Office
A three-layer model of an engineering system is proposed for developing and evaluating a resilient industrial control system incorporated within the engineering system, the model based upon a group of metrics that are cyclically estimated, operated and evaluated to create a valid resilient arrangement. The layers in the model include a human/operator layer, an automation layer and a process layer, where the industrial control system resides in the automation layer. The metrics are based upon the identification of a number of undesirable incidents, as well a determination of the frequency of occurrence of these incidents, their impact on the performance of the engineering system and the financial loss of the engineering system based upon these undesirable incidents.
