Question 1
Frank’s machine shop operates 250 days per year. Frank sells 5,000 units
per year of his most popular item, a specialty gear. The set-up cost for this
gear is £100 and the monthly unit cost of holding inventory is 1% of the
production cost per unit, which is £50. The lead time is 10 days. When the gear
is being produced, the shop can make 80 gears per day (Hint: You
should use the production model for inventory management.).
Complete the following:
1.
How many
gears should be produced in each run and at what minimum cost?
2.
What is the
cycle time?
3.
Find the
reorder point.
4.
Draw a graph
to depict inventory level against time and show on it the quantities found
above. Also, what is the maximum inventory level?
