Verification, Validation, and Accreditation of a Soldier-System Modeling Tool

Abstract

Increasingly, system developers are relying on modeling and simulation to support early design decisions. In turn, to support effective, timely use of models and simulations, verification, validation, and, in some cases, accreditation (VV&A) are required. The soldier-system analysis tools collectively known as Hardware vs. Manpower (HARDMAN) I11 underwent a formal VV&A process, the first of its type in the Army. The first phase comprised the core task network modeling capability and the effects implemented as additions to or modifications of the task data--mental workload estimation and environmental degradation, personnel characteristics, and training. A review board of representative users, policy-makers, technical experts, and soldier proponents evaluated the findings against eight criteria--configuration management, software verification, documentation, data input requirements, model granularity, validity of modeling techniques and embedded algorithms, output, and analysis timelines. All criteria were satisfied and formal accreditation was granted with only limited caveats.

Assessing physical workload for human–robot peer-based teams

“…The evaluation was intended to: (1) assess the applicability of the human-human condition workload performance functions to the human-robot condition and (2) validate the performance models. The humanhuman (H-H) and human-robot (H-R) models were developed in IMPRINT Pro (Allender et al, 1995;Archer et al, 2005). IMPRINT Pro (Alion Science and Technology, 2009) predicts a human's perceived levels of workload throughout a set of atomic tasks.…”

Human-Robot Teams Informed by Human Performance Moderator Functions

“…PMFServ has been used to model human behavior in many scenarios including hostile civilians in an urban military scene [79]. IMPRINT Pro is a task network modeling tool intended to assess human and system performance in military missions [3,5]. IMPRNT Pro has been used to model personnel on a United States Navy destroyer bridge, the U.S. Army's Crusader System [1], and pilot performance for simulated unmanned air vehicles missions [86].…”
