For the Case problem (JET Copies) the following components of the model were implemented below to describe in detail the thought process on the data input.

Probability of repair time:

On the basis of information available in this case problem, the repair time is determined through probability of occurring in one year. That is there is 20% chance to repair in 1 day, 45% chance to repair in 2 day, 25% chance to repair in 3 days, and 10% chance to repair in 4 days.

Random numbers:

There are 365 random numbers are selected through excel program sheet in order to determine average time between breakdowns, average repair time and average annual loss of revenue.

Interval between breakdowns:

The interval between breakdowns is the time it takes to end one task and begin the next. To determine the...
