A computer lab has a dozen machines, but at any given time some of them may be out of commission. Usually the problem is something as simple as the operating system locking up, which requires that a staff person reboot the machine and make sure that all the standard settings are correct. Sometimes the problem may be more serious, taking more time to correct. Overall, the repair time for any individual computer is negative exponentially distributed with a mean of thirty minutes. Once a computer is operating, the time until failure is negative exponentially distributed with a mean of ten hours.
a. If there is only one staff person to do the repairs, what is the average number of operating computers in the lab over the long run?
b. If there were two staff people to do the repairs, how much would that same average be?

Wally’s Widget Warehouse takes orders from 7 a.m. to 7 p.m. The manager wants to analyze the process and has provided the following process flow diagram. There are three steps required to ship a customer order. The first step is to take the order from a customer. The second step is to pick the order for the customer, and then they have to pack the order to ready it for shipping. Wally promises that every order placed today gets shipped tomorrow. That means the picking and packing operations must finish all orders before they go home.
Wally wants to figure out the following:
What is the current maximum output of the process assuming that no one works overtime?
How long will the picking and packing operations have to work if we have a day where the order taker works at his maximum capacity?
Given b, what is the maximum number of orders waiting to be picked?
Given b, what is the maximum number of orders waiting to be packed?
If we double the packing capacity (from 60 to 120 orders per hour), what impact does this have on your answers in parts (b), (c), and (d)?
