This project studied the incorporation of military occupational data into a generic human performance modelling software, the Integrated Performance Modelling Environment (IPME). It has explored the use of modelling and simulation (M&S) for addressing the CF personnel and manpower issues. Particularly, a set of Canadian Air Force occupational specification data were integrated into IPME. This reported study documents our effort to validate this new modelling capability. The Unmanned Aerial Vehicle (UAV) mission modeled in IPME was based on Kobierski (2004). The crew from the model consists of operators defined by the job-related task, skill and knowledge statements from the occupational data. Based on the task data incorporated in the model, we used a Job Similarity Index (Farrell et al., 2006) as an indicator for predicting operator performance. To confirm the validity of this approach, we originally planned to replicate the same UAV model in US Army’s IMPRINT and compare the performance predictions made by these two different modelling toolkits. However, due to the lack of access to IMPRINT, the Integrated Simulation Manpower Analysis Tool (ISMAT) was used. As a personnel modelling tool, ISMAT was developed primarily for targeting naval applications. As a result, this study focused on comparing the different personnel modelling approaches between IPME and ISMAT. Their differences are documented in this report, with a highlight on future IPME research and development d
