Determines the test time required to demonstrate Availability was met with Confidence

Description

ao_keesee_test_duration determines the test time required to demonstrate Availability was met with confidence, assuming a nunmber of failures, repairs, and mean time to repair (MTTR) (an optionally Admin/Logistics Delay Time (ALDT), Mean ALDT (MLDT), and the number of observed ALDTs).

Usage

ao_keesee_test_duration(n, m, k = NA, mttr, mldt = NA, ao, alpha = 0.4)

Arguments

n	Number of failures.
m	Number of repairs.
k	Number of Admin/Logistics Delays (set to NA as default to exclude ALDT).
mttr	Assumed mean time to repair.
mldt	Assumed mean logistics delay time (set to NA as default to exclude ALDT).
ao	Availability to be demonstrated.
alpha	Two-sided alpha value.

Value

The output will be a numeric vector giving the required Up Time, assumed Down Time, and Total Time.
