Analysis of a Stochastic Model for Communications-Electronic Systems Failure Rates Using Dyna-Metric

Abstract

The current CE WRSK configuration process is not standardized. There are many different inputs used by AFLC to determine requirements. A model to predict CE system failure rates has been developed and validated. This model separates failures into two catergories, on-time failures and cycle-up failures. This validated model was tested, using Dyna-METRIC, against two other possible failure rates. These failure rates were based on (1) possessed hours and (2) on- time hours. The stockage runs produced by Dyna-METRIC were compared to actual failures over a 120 day time period. The validated model produced a higher stockage level, as well as lower MSE than the other two failure rates. The current failure rate used by AFLC to aid in CE WRSK configuration showed a discernible trend to underestimate stockage levels. The Air Force should use the validated model to determine CE WRSK configuration and implement the appropriate policies and data gathering systems. Keywords: Theses, Logistics management.
