		----- REPORT CONTENTS -----

 THIS SECTION DESCRIBES THE FORMULAS USED IN THE MAIN REPORT.

SYSTEM AVAILABILITY - THIS IS COMPUTED USING THE FOLLOWING FORMULA.
 S.A. = 1.0 - (TOTAL DOWN TIME / OPERATIONAL CYCLE)
  WHERE DOWN TIME IS THE TIME 'CHARGED AGAINST AVAIL.' AS DETERMINED BY
THE WHY RELOAD ANSWERS.
  OPERATIONAL CYCLE IS THE CLOCK HOUR TIME PERIOD OF THE INPUT FILE COMPUTED
FROM THE FIRST SYSTEM RELOAD ENTRY TO THE LAST CRASH INCLUDED IN THE FILE.

USER AVAILABILITY - THIS IS COMPUTED BY
 U.A. = 1.0 - (TOTAL DOWN TIME/(TOTAL DOWN TIME + TOTAL MONITOR RUN TIME))

MONITOR RUN STATISTICS ARE COMPUTED USING THE TOTAL NUMBER OF RELOADS INCLUDING
BOTH THOSE 'CHARGED TO DOWN TIME' AND THOSE 'NOT CHARGED.'

SYSTEM EFFECTIVENESS CONSIDERS BOTH THE PROBABILITY OF THE SYSTEM BEING UP
AT TIME ZERO (SYSTEM AVAILIBILITY) AND THE PROBABILITY OF THE SYSTEM STAYING UP
(SYSTEM RELIABILITY)FOR SOME TIME PERIOD "T".
  4 VALUES ARE CALCULATED FOR TIME PERIODS OF .1HRS,.5HRS, 1.0 HRS, AND
4.0 HRS USING THE FORMULA:

 S.E. = (1.0 - (DOWN TIME/OPERATIONAL CYCLE) * (e ** (-T/MTBF))

  MTBF = TOTAL MONITOR RUN TIME / # OF RELOADS CHARGED TO DOWN TIME 
     IT IS ASSUMED THAT USUALLY NO USERS JOBS ARE STILL ACTIVE WHEN THE
  SYSTEM IS BROUGHT DOWN INTENTIONALLY.
