Miso Computer produces computer parts and buys platinum from one
of its suppliers. Each part carries 1 ounce of copper. Annual
demand for parts follows a normal distribution with an average of
7000 parts and a standard deviation of 2000. The copper supplier
takes 5 weeks to deliver the material after the order is placed.
Miso uses 40% annual interest to compute the cost of maintaining
inventory. Copper buys it at $0.25 per ounce. The company uses a
short material cost of $25 per ounce of copper and putting an order
to the supplier costs $80. Note: Show off 52 weeks in a year.
Careful with unit conversion.
a) Suppose Miso is interested in the decision to ensure that 85% of
cycles meet all demand:
i. What should be the lot size? (whole number):
ii. And the size of the reorder point? (whole
number):
b) Assume that you want to calculate the average total cost of
annual inventory, including setup, material maintenance cost, and
short cost; provide the individual values for each of these terms
(two decimal places, annually):
i. "Setup":
ii. Keeping the material:
iii. Costos por cortos de material:
c) What type 1 service level are you guaranteeing
with the system in part a? (provide service level in percentage
terms, two significant decimal places):
d) What type 2 service level are you guaranteeing with the system
in part a? (provide service level in percentage terms, two
significant decimal places):
