Abstract : This report focuses on the development and application of new mathematical algorithms for blood flow, sweating rate, and cardiac stroke volume for use in SCENARIO, a previously documented simulation of physiological responses to work in hot environments. The new algorithms make for the subject's level of aerobic fitness and the extent of dehydration which can progressively deteriorate performance during sustained exposures. Graphic examples of SCENARIO output are given for sustained work in the normal, euhydrated state and compared with examples of progressive dehydration and of deteriorated physical fitness due to 20 days of bed rest. An novel example of its use as a tactical decision aide is given.
