exp_reliability_req: Calculates the Reliability Requirement

In jjw3952/mcotear: Contains helpful functions for use within MCOTEA

Calculates the Reliability Requirement

Description

exp_reliability_req calculates the Reliability requirement based on a defined Mean Time Between Failure (MTBF) (really we use Mean Time Between Operational Mission Failure (MTBOMF)) requirement, and mission duration. (Instead of Time, Miles, Rounds, etc. may be used.) This assumes the times (miles, rounds, etc.) between failure are exponentially distributed.

Usage

exp_reliability_req(mtbf, md)

Arguments

mtbf	A numeric MTBF requirement. This could be time, miles, rounds, etc. Units should match the md parameter.
md	A numeric mission duration. This could be time, miles, rounds, etc. Units should match the mtbf parameter.

Value

The output will be a numeric vector defining the Reliability requirement, (the probability that no failure is observed during the given mission duration).

Examples

# What is the required Reliability if the MTBF is 228 hours and
  # a mission duration of 24 hours?
exp_reliability_req(mtbf = 228, md = 24)
