A Powerful Strategy for Analyzing Large-Scale Mass Circulation Networks in CELSS

(2) Characteristics of CELSS Networks and Modification of Fundamental Theory

Abstract

To characterize CELSS (Closed Ecological Life Support Systems) networks, two kinds of simple closed system models that have two- and four-dependent variables, respectively, are investigated. The CELSS matrix, which is directly yielded within the framework of BST (Biochemical Systems Theory) in a steady state, is singular and does not provide steady-state values for the dependent variables. Nevertheless, in dynamic calculation the dependent variables converge on their respective constant values, which is a contradictory behavior to common sence. This is because of the existence of an alternative equation derived from the law of conservation of mass, which equation is characteristic of CELSS and is automatically satisfied in calculation. On the basis of this finding, BST is modified so as to adapt to the analysis of large-scale mass circulation in CELSS.
