Abstract:

To determine the situation awareness performance of C4ISR quantitatively, the situation awareness process, from perception to comprehension, based on Endsley’s situation awareness model. Three fundamental empirical postulations on situation understanding process are given together with a measurement on time dependent situation difference. Differential equations are established to describe the relation between the rate of situation changing and situation awareness. A modified method is given to improve the performance factor about situation awareness. The analysis results of these differential equations are in conformance with real world experience.
