title: A hierarchical approach to the sustainable management of controlled ecological life support systems: part 2, systems realization and analysis.
abstract: The second in a series of two articles exploring the sustainable management of a controlled ecological life support system (CELSS), this article examines the feasibility of the approach outlined in Part 1 using a simple, abstract CELSS representation comprising buffers and pumps. We develop a two-level management hierarchy in which the top level imposes constraints on the operation of the lower level. The compartments can operate freely within these constraints. This freedom can be used to enhance system performance and robustness. Additionally, the higher level does not require detailed subsystem representations. Our approach to sustainable management of CELSS allows for the active distribution of system mass, taking into account component constraints and system dynamics.
