Problem 2: Yes, it is possible to have both high flow time and inventory, or have them both low. I would rather have a low inventory with a low flow time, because it means that the process would have a low waiting time.
Problem 3:
1. I = $100M R = $400M+$200M/year T = I/R
100/600 = .16 years => 2 months; The avg. dollar spends 60 days in the process.
2. I = RxT R = 10,000/year T = 3 weeks => 3/50 (office weeks)
10,000 x 3/50 yr = 600 claims at any given points
Problem 4:
Nissan Motor Company reported a total of $180M in revenues in the past year. On average, during one year Nissan Motor Company has a warehouse and dealership inventory of $12M. It has been discovered that Nissan Motor Company has a motor vehicle markup of about fifty percent. What is the average time that motor vehicles are in warehouse or dealership inventory before they are sold?
I= $12M, R= $180M/year, T=?
T=I/R => $12M/$120/year= 0.1 yrs
