Extravehicular Activity (EVA) will be required for maintaining the Space Station Freedom during both the assembly phase of the program (1995-1999) and steady state, or permanently manned configuration.. Currently, several contractors are involved in the developing of the external hardware which will interface with the EVA crewmember. This hardware includes: the Extravehicular System; Unpressurized Logistics Carrier; the robotic systems; and all external orbital replacement units (ORUs). An integrated analysis of the hardware is essential to design an overall system which is not only EVA compatible, but also allows the EVA crew to optimize their workload during external maintenance activities. The use of graphic simulations of end-to-end external maintenance activities offers a relatively inexpensive method to identify design and operational concerns of the integrated hardware.
