Section B: Analytical Problems (40 marks)
This section consists of Analytical Problems.
Answer all the questions.
Each Question carries 10 marks.
Detailed information should form the part of your answer (Word limit 200 to 250 words).
1. Calculate the available to promise (ATP) using the following data. There are 100 units on hand.
Week 1 2 3 4 5 6
Customer Orders 70 70 20 40 10
MPS 100 100 100
ATP
2. Given the following data, can an order for 30 more units delivery in week 5 be accepted? If not,
what do you suggest can be done?
Week 1 2 3 4
Forecast 80 80 80 70
Customer Orders 100 90 50 40
Projected Available
Balance
140
MPS
3. Given the following parents and components, construct a product tree. Figures in parentheses
show the quantities per item. How many Gs are needed to make one A?
Parent A B C E
Component B(2) E(2) G(2) G(4)
C(4) F(1) F(3)
D(4) H(2)
4. An order for 100 of a product is processed on operations A and operations B. the setup time on A
is 50 minutes, and the run time per piece is 9 minutes. The setup time on B is 30 minutes, and the
run time is 6 minutes per piece. It takes 20 minutes to move a lot between A and B. since this is a
rush order, it is given top priority (president’s edict) and is run as soon as it arrives at either
workstation.
It is decided to overlap the two operations and to split the lot of 100 into two lots of 60 and 40.
When the first lot is finished on operation A, it is moved to operation B where it is set up and run.
Meanwhile, operation A completes the balance of the 100 units (40) and sends the units over to
operation B. These 40 units should arrive as operation B is completing the first batch of 60; thus,
operation B can continue without interruption until all 100 are completed.
a. Calculate the total manufacturing lead time for operation A and for B without overlapping.

saved?

1. Suppose a manufacturer makes wagons composed of a box body, a handle assembly, and two

3. Suppose management stated that it could tolerate only one stock out per year for a specific item.
For this particular item, the annual demand is 52,000 units, it is ordered in quantities of 2600, and
the standard deviation of demand during the lead time is 100 units. The lead time is one week.
Calculate:
a. Number of orders per year.
b. Service level.
c. Safety stock.
d. Order point.
4. Delivery of goods from a supplier is in transit for ten days. If the annual demand is 4200 units,
