Suppose 50 people come to a fast food take-out restaurant each hour. There are four employees, one at the register, two making the food, and one packaging the food. Suppose on average, each order takes 30 seconds at the register, and it takes one employee an average of 1.5 minutes to make the food, and it takes 1 minute on average to package the food. Assume exponential arrivals and service times.
1) How many people typically are waiting in line to place an order?
2) How many people are waiting for their food to be made?
3) How many people are waiting for their food to be packed?
4) Which is the bottleneck of the process? Taking orders, making food, or packaging food?
5) How many customers per hour can the restaurant serve?
6) If the restaurant hires one more employee, which process should the new employee be placed?
7) How many customers per hour can the restaurant serve if that's the case?
Assuming the new employee can achieve the same efficiency as existing employees.
