Application of RAMCOST-II simulation model to space suit (kit-inventory) during a mission

RAM ( R eliability, A vailability, and M aintainability) parameters have been known to be a predominant factor in inventory planning of perishable items. However, the existing models have been developed and applied in piece-wise cases. In this paper, we discuss a system application of RAM factors in planning space suit inventory during extra-vehicular activities (EVA) for a space mission. The model is implemented in the RAMCOST-II Simulation environment. RAMCOST-II is a logistics-based simulation platform which integrates RAM factors and life cycle COST ing during a design.
