The closed ecology experiment facilities(CEEF) are comprised of an animal breeding & habitation module, plant module, and a geo-hydrosphere module(currently being established), which are composed of physicochemical devices to allow almost all the material to be circulated. Partial test operations are now in progress with these kinds of equipment, and cooperative operations between an animal breeding & habitation module and plant module are expected to be started in the near future. Balance of the material and equipment performance as the whole of the system are being tested, and material circulation in a variety of operation modes is being examined. Keeping such a situation in mind, analysis is made in this report for material circulation in the plant module by itself for operations based on the equipment design data.

Material circulations in a lunar base were simulated in consideration of an optimum control of electric power distributions to equipment. The base is composed of habitation and cultivation modules. The simulations of a dynamic logistic problem were conducted by the use of a fuzzy programming method, after doing the biochemical stoichiometric formulation of crew-, plant-, and machine-subsystems in living and growing modules. The simulation model could treat material circulation and electric power distribution in space systems and it could be expected to make this tool powerful combining this with experimental data.
