exp_mtbf_req: Calculates the Mean Time Between Failure (MTBF) Requirement

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

Calculates the Mean Time Between Failure (MTBF) Requirement

Description

mtbf_req calculates the Mean Time Between Failure (MTBF) requirement based on a defined Reliability 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_mtbf_req(R_m, md)

Arguments

R_m	A numeric mission Reliability requirement (0.00:1.00).
md	A numeric mission duration. This could be time, miles, rounds, etc.

Value

The output will be a numeric vector with units the same as the mission duration.

Examples

# What is the required MTBF to have a 90% prob of
  # completing a 24 hour mission duration?
exp_mtbf_req(R_m = .9, md = 24)
