The objective of this study is to develop time series models of the controller mechanisms of the human temperature regulating system. The controller responses are: changes in metabolic heat production, changes in evaporative heat loss and alterations in the surface blood flow. After evaluating the models developed for the controller mechanisms, the models are validated in the context of a complete simulation model of temperature regulation. Additionally, upper and lower limits are set for the controller responses. Because of the nature of the data available for surface blood flow, this controller response is not represented by time series models. Published data and time series techniques are used for modeling purposes. A set of models is developed for all temperatures combined and for ranges of temperatures in both air and water environments. Published simulation models are used for validation of the models.
