14.8 As the production planner for Scott Sampson
Products, Inc., you have been given a bill of material for a bracket
that is made up of a base, two springs, and four clamps. The base
is assembled from one clamp and two housings. Each clamp has
one handle and one casting. Each housing has two bearings and
one shaft. There is no inventory on hand.
a) Design a product structure noting the quantities for each item
and show the low-level coding.
b) Determine the gross quantities needed of each item if you are
to assemble 50 brackets.
c) Compute the net quantities needed if there are 25 of the base
and 100 of the clamp in stock.
Your boss at Scott Sampson Products, Inc., has just
provided you with the schedule and lead times for the bracket in
Problem 14.8. The unit is to be prepared in week 10. The lead
times for the components are bracket (1 week), base (1 week),
spring (1 week), clamp (1 week), housing (2 weeks), handle
(1 week), casting (3 weeks), bearing (1 week), and shaft (1 week).
a) Prepare the time-phased product structure for the bracket.
b) In what week do you need to start the castings?
