Mission Reliability Model Programmers Guide.
Abstract
The Mission Reliability Model (MIREM) has been developed to evaluate the reliability and sustained operating capability of advanced electronic circuits during the early stages of development. MIREM is applicable to integrated systems that achieve fault tolerance through dynamic fault detection, fault isolation, and reconfiguration. The model can also be valuable in evaluating designs that employ only dedicated or hard-wired redundancy. The most unique feature of MIREM is its ability to accurately reflect the impact of reconfigurable, competing functions on system reliability. The user defines the resources necessary to support a required function, e.g., Global Positioning System (GPS), and the model will compute the probability of losing that functional capability over a certain operating time. A critical failure occurs when there are not a sufficient number of working resources to support a specified function. As an analytic model, MIREM determines a value for Mean Time Between Critical Failure, Mission Completion Success Probability, and Failure Resiliency. The MIREM Programmers Guide addresses the model's program structure, function of routines, interdependence of subprograms and common blocks, and file usage. The information needed to port the model to other computer systems is also provided. Keywords: avionics; maintainability; mathematical models.
