Tools for Including Realistic Representations of Operator Performance in DOD Constructive Simulations

摘要

Military weapon systems are normally built to satisfy a set of requirements levied by the warfighter. All these weapon systems are manned in some sense, yet tools for quantifying the effectiveness with which a crewstation must support operator performance are lacking. Analysts and decision-makers need a means to readily model and understand the effects of human performance on total weapon system effectiveness when translating operational requirements into system requirements. This paper discusses the research and demonstration activities being conducted by the Combat Automation Requirements Testbed (CART) Program within the Air Force Research Laboratory / Human Effectiveness Directorate. CART will demonstrate how human-in-the-loop and constructive operator models and data can be integrated with Simulation- Based Acquisition activities for the purpose of defining crewstation requirements. Utilizing the Army's IMPRINT human-performance modeling environment, CART will provide High Level Architecture (HLA) interfaces that enable human-performance models to interact with constructive models of systems. A second extension will incorporate the ability to represent the goal- oriented nature of human performance. Modelers and analysts will be able to define operator goal states and priorities that dynamically drive task network models based on changing states and events in simulated military environments.
