For the Royal Canadian Navy’s (RCN) Human Factors and Crewing Program (01AB), DRDC is investigating the impact of introducing advanced automation on crewing. The recent modernization of the RCN’s twelve Halifax-class frigates has allowed DRDC to examine ops room crewing relative to two main pieces of automation: (a) data fusion for picture compilation and (b) threat evaluation and weapons assignment (TEWA) automation. For each of these pieces of automation, DRDC tested operator performance using simulation software. For data fusion for picture compilation, a testbed was developed that allowed us to examine participants building a maritime picture with or without data fusion. For TEWA, we employed the Combat Resource Allocation Support (CORALS) simulation and ran RCN operators through several high tempo anti-air warfare missions using advanced TEWA capabilities. For each of these projects, metrics were developed to measure individual and crew performance under different mission, automation, and crewing conditions. This document describes the calculation of these metrics. Part I describes thirteen picture compilation metrics. Part II describes eleven metrics for Threat Evaluation, five for Weapons Assignment, and three relative to mission success.
