Abstract
The importance of understanding human body requirements can not be ignored in order to create a successfully working Advanced Life Support System. A generic model was created to capture these requirements at the primal levels. The model acounts for the main four elements listed as Carbon, Oxygen, Hydrogen and Nitrogen. The activity level, as well as gender and body weight are considerd in the model to calculate the appropriate energy requierements for the crew members. Given the energy level for crew members, the model then generates daily Protein, Carbohydrate and Fat intake necessary to meet the energy requirement in units of Kg/CM-d. The drinking water at this point is independent of the activity level and is assumed to be constatnt at the leves dictated by the BVAD. The elemental compositions of Protein, Carbohydrate, Fat and water (inputs) are used to calculate the amount of solid and liquid waste (outputs ) generated by the body. Known elemental compositions allow for mass balance. Although the model is accountable to a certain degree, at this stage it fails to include factors such as age, sleep quality, sleep duration, psychology of the crew members and other environmental conditions due to lack of data.
