Currently, the measures of performance used by the Military Airlift Command, in particular departure reliability, emphasize activities. In so doing the productivity of the MAC airlift system is overlooked. A factorial design experiment was conducted with a simulation model of a portion of the MAC airlift system. Results from this experiment indicate that an activity index like departure reliability does not track system output, and, consequently, should not be regarded as a measure of system productivity. A set of productivity ratio indices was computed using the model inputoutput data from the system simulation. By emphasizing the relationship between output and input these ratio indices highlight system productivity and enable the MAC Commander or the airlift managers to make appropriate decisions regarding system productivity. In addition, productivity ratio measures have the potential for improving contingency planning by providing planners the ability to relate required output capacity to needed input resources, and also to determine output capacities constrained by input resources.
