Consider the following 5 station system, which has a higher arrival rate to station 5 due to necessary re-work at that station. What is the minimum cost, capacity feasible number of machines to install at Station 4 ? Question 4 3 pts Using the same information as above, what is the optimal number of machines to put at station 1 in order to keep total cycle time under 2.5 hours? Assume the arrival coefficient of variation to station 1 is 1. Question 5 2 pts Which of the following is an example of an economy of scale (i.e. NOT an example of a dis-economy of scale)? Products have a higher average distance to go to arrive at customers if there is only one warehouse instead of ten. The cost of putting ten new machines in is $200,000, but the cost of putting twenty new machines in is $250,000. Company A built a huge manufacturing facility in Cincinnati, while their competitor, Company B, built two medium sized facilities (one in Cincinnati and one in Indianapolis). An ice storm knocks out the power to all of Cincinnati, rendering all of Company A inoperable.
