1.Tinyfield Labs' first process is performed at a bottleneck station that has one machine working on a NON-batched process. It takes this machine on average 5 hours to process a job. That is, the capacity of Tinyfield Labs is 4.8 jobs per day. Starting in the next month, the expected (average) daily demand is 21.8 jobs per day. Obviously Tinyfield does not have enough capacity. Tinyfield needs to buy more (exactly the same) machines at this first station. What is the minimum number of machines Tinyfield needs to have at this station in order for this station to have sufficient capacity > average demand?

(Hint: 4.8xWhat Integer? You can try a number of options and see what's the smallest integer number of machines that will give you a capacity > average demand. Note that the capacity needs to be > average demand, not =. Think about why.)

2. Tinyfield Labs' first process is performed at a bottleneck station that has 5 identical machines working on a NON-batched process. A job can be taken by any one of the unoccupied machines and needs to be processed by only one of the machines at this station. It takes a machine on average 5 hours to process a job. The expected (average) daily demand is 18 jobs per day to arrive at Tinyfield. What is the capacity utilizaton of this station?

3. Tinyfield Labs' first process is performed at a bottleneck station that has 5 identical machines working on a NON-batched process. A job can be taken by any one of the unoccupied machines and needs to be processed by only one of the machines at this station. It takes a machine on average 5 hours to process a job. Average job arrival rate (demand) at Tinyfield is 16 jobs per day. It is observed that the average WIP at this station that includes jobs occupying machines as well as jobs waiting in front of the station, is stablized at 12 jobs as a long run average. How long does a job needs to spend at this station? (Hint: this is the cycle time at this station that includes waiting time and actual processing time. Apply the Little's Law. Make sure you realize what time unit you are using in the calculation.)
