An application-oriented multiprocessing system, IV: The operational error analysis program

The use of multiprocessing in the Federal Aviation Administration's (FAA's) air traffic control application has necessitated the development of a new type of program—the Operational Error Analysis Program (OEAP). Such a program performs on-line analyses of equipment failure indications concurrently with regular processing, and assesses the source and seriousness of each potential malfunction. If necessary, the program realigns the communication and control paths in the multi-element system to functionally replace failing elements by redundant elements.
