Answer:
The frequency by which the equipment should receive periodic maintenance is
Step-by-step explanation:
A Wellbull distribution is mathematically represented as
Where x is the frequency that the equipment should receive periodic maintenance
probability of a breakdown before the next scheduled maintenance is mathematically represented as
Substituting 2 for and 60 for 0.05 for P(x)
Let
=>
=>
Multiply both sides by minus
=>
Substituting this into the equation
Integrating and substituting back for x
substituting for the range of x and 0
Taking ln of both sides
making x the subject of the formula
9514 1404 393
