“…HERITAGE shares more comparative points with virtual habitat models. In particular, the V-HAB model developed by the Exploration Group in Munich [70,71,72] includes a dynamic representation of the crew to be integrated in any LSS. The human model includes a much more sophisticated representation of the human body (lungs, heart, kidneys, fluids ...) and very precise estimations of the water, food and breathable gases intake can be achieved.…”

“…The V-HAB model works very well when compared to ISS data and can be used to prepare a Mars colony with reliable numbers. Nevertheless, the human model in V-HAB remains static, in the sense that only standardized, active, male adults can be modelled [72]. HERITAGE accounts for gender, age, size, weight and genetic diversity.…”

The architecture of a large interstellar spaceship, which is capable of serving as a living environment for a population over many generations, is mainly dictated by the needs of said population in terms of food, water and breathable gases. These resources cannot be stored for the entire duration of a journey that goes on for several centuries, so they must be produced in situ. In order to determine the quantities necessary for the survival of the population, it is imperative to precisely estimate their needs. In this article, we focus on accurate simulations of the water and air (oxygen) requirements for any type of population in order to be able to provide precise constraints on the overall architecture of an interstellar ark (the requirements in terms of food having already been studied in a previous publication). We upgrade our agent-based, numerical, Monte Carlo code HERITAGE to include human physiological needs. Our simulations show that, for a crew of about 1 100 crew members (each characterized with individual anthropometric and biological data), 1.8 × 10 8 litres of oxygen are annually required, together with 1.1 × 10 6 litres of water. Those results do not account for oxygen and water used in growing plants, but they give us an insight of how much resources are needed in the spaceship. We also review the best methods for generating water from waste gases (namely carbon dioxide and dihydrogen) and how such system could complement the oxygen-supplying biospheres inside multi-generational spaceship to form a closed and controlled environment.

“…LabVIEW software was used in designing as it has the necessary modelling tools, providing users with visualisation, and allowing integration with hardware equipment, sensors, and monitors. The structure of the developed system includes: power sub-system linked with all other systems as every system requires a certain amount of energy; thermoregulation sub-system which has a decision support option, models of LSSs, model of environment, human model, a logical model of failure settings which is related to the CONTROL element (see in Fig.1) [6][7][8][9]. Verification of the models was based on algorithm tests on contradictoriness, results correlation analysis and ergonomic evaluations.…”

The human health condition and operating capability depend on a variety of environmental factors. It is of great importance to perform studies addressing these factors and their influence on humans as it can help to form an optimal strategy in emergency situations and help humans to attain maximum performance. The best results are shown in studies performed in isolation in a man-made ecosystem because in this case environmental processes are defined and controlled. Man-made ecosystems include a life support system (LSS) combined with the environment and a key element-human. The research defines these three components as a complex system. This study is dedicated to interaction analysis and the human safety in this system, especially in case of emergencies. It includes supporting simulation models based on two types of experiments conducted by the researchers, namely the studies on the mean time to failure (MTF), and on human behavior during emergencies. The basic imitators of life support systems are complemented by additional environmental models where a human is represented as a loading element. To prevent hazards in low performance situations, the simulator used during the experiment, had a decision-making system, controlling environmental parameters and taking actions for the stabilization. It could also control the human condition, such as pulse, pressure, etc., during the entire operation. The results of the studies showed the dependency of human performance on fatigue, the time spent in isolation, as well as the emergencies. The methodology recommendations and safety requirements are discussed in the paper. The results of these studies were used in forming an information database for automated control system of the "artificial lungs" equipment.
