1. A method for determining an availability of a complex system, the method comprising:

  • receiving information related to system-hardware components and operating-system components and configuration and compiling a first, intermediate, system-availability-related result with respect to the system-hardware components and operating-system components;

    receiving information related to non-operating-system software components and configurations and compiling a second, intermediate, system-availability-related result with respect to the non-operating-system software components and configurations;

    receiving information related to planned system downtimes and compiling a third, intermediate, system-availability-related result with respect to the planned system downtimes;

    combining the first, second, and third intermediate system-availability-related results to produce a combined availability result; and

    determining the availability of the complex system by calculating the availability of the complex system from the combined availability result.
