The daily demand for parts from machining workcell JMB to an assembly workcell is 1,600 units. The average processing time is 25 seconds per unit. A container spends, on average, 6 hours waiting at JMB before it is processed. Each container holds 250 parts. Currently 10 containers are being used for the part.
a. What percent safety margin of stock is being carried?
b. If you wanted to retain this safety margin, but remove one container, to what value must the waiting time be reduced?
c. What would happen if the demand for parts increased to 1,900 with K = 10?

A product has a daily demand of 26 units per day. Ordering costs
are $60 per order. The annual carrying costs are measured at 20% of
item value. Your supplier has offered you three item cost/price and
quantity scenarios (1) you pay $150 per unit if your order quantity
is 199 units or less, (2) you pay $121 per unit if your order
quantity is between 200 and 4999 units, and (3) you pay $114 per
unit if your order...
