[文摘]:A conceptual study for a computational simulator of material circulation in a CEEF was performed. CELSS such as the CEEF (Closed Ecology Experiment Facility), which is under construction at the Institute for Environmental Sciences, have many physicochemical devices. To simplify their programming, many physicochemical devices were classified into several function groups using C++, a specially designed programming language to support the object oriented programming technique. Based on the classifications, the simulation software was made, and a simulation was performed. The simulation results predict that stable operation of CEEF can be obtained. (Author)
