In system integration, it is important to understand the mechanism of each subsystem before building the entire system. This poster illustrates the BREATHe I, BREATHe II, RO/NF, liquid phase UV-Iodine, and gas phase UV from a system analyst's point of view. In other words, these subsystems are treated as black boxes and the concerns here are to evaluate the input and output elements going into and out of a black box, especially on the major compounds such as water, oxygen, carbon dioxide, and nitrogen. A few assumptions are made in building these models as some of the experiments are still in on-going process. For instance, it is assumed that there is no leakage in the subsystem, 100% efficiency of a particular subsystem, etc. These assumptions may be relaxed when further information from experiments or simulation results are gathered. These models will serve as "pieces of jigsaw puzzle" that are going to be "assembled" together and become a big model known as the first order model. This model is expected to be able to trace the flow of major compounds (ie. Water, oxygen, carbon dioxide, and nitrogen) in the entire advanced life support system.
