Lost revenue of Jet Copies due to breakdown can be done by generating random numbers from different probability distributions according the given probability law. The different steps of this simulation and assumption made are explained below. 1. Simulation for the repair time.

To generate a random number from the above distribution, we use the following procedure. Generate a random number denoted by r2 from between 0 and 1. If this generated random number is less than or equal to 0.2 take repair time = 1. If the generated random number is 0.2 to 0.65, we take repair time =2. If the generated random number is 0.65 to 0.90, we take repair time = 3 and take 4 otherwise. 2. Simulation for break-down Distribution

Given that the probability distributions of random variable X representing the time between break-downs varies from 0 to 6 weeks with probability increasing continuously, the copier went without breaking down can be approximated by the probability distribution

f(x) =x/180 < x < 6
Hence the distribution function of x is
F(x)=x2/360 < x < 6
If r1 is another random number generated between 0 and 1, then we can write
r1= x2/36
Hencex=6[pic]
Therefore to simulate from the break down distribution, generate a random number r1 between 0 and 1 and make the transformation, x=6[pic].

Days for Repair-
The information that was provided to the researcher included the facts that the repair would take somewhere between 1 and 4 days. Included along with the number of days was the probability of the repair being completed on each individual day. The first step in the simulation process was to assign ranges to each day. Day 1 received the range 0-0.2 (because it had a...

...This caseproblem was an interesting problem to work. In order to simulate the intervals between breakdowns, the estimated time between breakdowns was needed. A random number was generated as part of the needed information to determine the interval. Once the random number was generated, a formula using the random number and the maximum numbers of weeks between breakdowns were used to calculate the weeks between breakdowns. Using the answer to that...
