A Systems Engineering Evaluation Method for Piloted Aircraft and Other Man-Operated Vehicles and Machines. Appendix D. A Unifying Set of Hypotheses for Dynamic System Test and Evaluation: The Rating and Measurement of System Perfo

摘要

A set of equations, definitions, symbols, units of measurement and an equal interval scale providing an equal interval unit rating and measurement method for system evaluation are presented. The objective is to provide a unified approach to the systems engineering evaluation, rating and measurement of a dynamic system. The equations present the hypothsized relationships between system ratings and system measures of performance, work, and load. An equal interval, one-tenth power of ten, scale with ten as the highest rating is introduced for the rating, measuring, and communicating system performance, work, and load factors. These factors are of increasing interest during early R&D system dynamic simulation concept testing and later operational system test and evaluation. (Author)
