VECTOR: An Analytic Tool for Planning and Predicting Aircraft Spares Support

摘要

A computer program which is called Vector can estimate how the number of mission-capable aircraft in a flying unit responds to changes in flying program, stock levels, the repair process, and so forth. Even though PACAF's Vector and Rand's Dyna-METRIC both are based upon the same sophisticated mathematics, blind acceptance of the output from such black box models weakens any argument as to whether the models have been correctly applied. This report takes the reader through a careful, step-by-step interpretation of the output of Vector and relates the output conclusions to the input data and to the built-in assumptions of the mathematics.
