Long Term Material Circulation Control and Handling Repair Order in ALSS by Hierarchical Approach

An Advanced Life Support System (ALSS) achieve life support in the ultimate environment by regenerating materials in the system. Because of their complexity of material circulations in ALSS, it is difficult to control whole-system material circulations and to handle on abnormal situations. Because of this, we had proposed hierarchical and autonomous circulation control methodology and had constructed automatic order determination system to deal with failure machines. In this paper, we calculated material circulation for 360 days with several machine failure events. As results, is was confirmed that our hierarchical procedure was useful.
