Abstract
This paper discusses two of the six software tools which are being developed as part of the Army Research Institute's MANPRINT Methods development program. The first tool discussed here is known as the System Performance and RAM Constraints Aid or SPARC. This tool permits system designers to determine levels of subfunction performance which are required to achieve function and higher level mission requirements. These levels of subfunction and function performance then serve as requirements which are fed into the second tool, the Manpower Systems Evaluation Aid (MAN-SEVAL). MAN-SEVAL takes as input the system design and then predicts the operator and maintainer manpower required to achieve the required levels of task and function performance. For maintenance manpower evaluation, MAN-SEVAL considers component failure rates, time to perform maintenance, and the mission scenario. For operator manpower and to estimate maintenance task times, MAN-SEVAL conducts an analysis of workload, control/display accessability, and maximum acceptable performance time to allocate tasks across crewmembers. Because all manpower requirements are truly driven by system performance requirements, these two tools are being developed collectively with common data bases and software design. While they are currently being developed for the Army, they will be useful general purpose manpower analysis tools.
