Predicting Radiation Induced Performance Decrements of AH-1 Helicopter Crews.Volume 2. Evaluation of Modeling and Simulation Techniques for Predicting Radiation Induced Performance Decrements

摘要

This report is the second in a series that investigates the effects ofintermediate doses of ionizing radiation on Army helicopter crew performance. This report documents the analysis of performance on the Walter Reed Performance Assessment Battery (WRPAB), and the development of an initial model for the WRPAB using Multidimensional Scaling (MDS) techniques. The WRPAB was used in a study where 20 AH-1 pilots (1) predicted the effects of various symptom complexes on their performance, (2) went through a 36-hour protocol to induce symptoms similar to symptoms that follow exposure to intermediate doses of radiation, (3) performed a simulated AH-1 mission before and after symptom induction, and (4) were administered the WRPAB approximately every 2 hours throughout the 36-hour protocol. MicroSAINT models for AH-1 tank engagements were developed that used PAB performance to predict AH-1 performance degradation. The results indicate that the WRPAB (or some other test battery) has utility for the prediction of operator performance as affected by stressors such as ionizing radiation.
