Expanding the domain of systems analysis
Article Abstract:
Systems often contain a human component. The human reacts, interprets, errs, ...succeeds or fails. However, usual analyses of such systems omit the human component, concentrating instead on the, more easily analyzed, software and hardware subsystems. A technique has been developed for including human decision processes by the use of an expert system in a systems analysis. This technique is applied to surveillance systems consisting of sensors which respond to stimuli and the interpretation of these responses by human. The analysis is carried out via simulations of hardware responses to stimuli, simulations of human interpretations of those hardware responses, and a measure of the performance of the total system. While the technique was applied to a particular system, the inclusion of simulations of human decision processes is essentially independent of the application.

Analytic performance estimation for complex maintenance systems
Article Abstract:
Earlier models are extended and combined to provide an analytic means of estimating the average number of inoperative machines in a two-echelon (bases and a depot), two-indenture (machines have components which may have modules) maintenance system with spares and repair. Separate expressions are developed for the no cannibalization and complete, instantaneous cannibalization cases. The expressions are suitable for verification of aircraft maintenance system simulation models as well as for estimation of system performance and the maximum benefit of cannibalization.
