QUESTION #1
The figure shows the manufacturing processes,
weekly market demands, unit revenues, and raw
material requirements for two products. The
products pass through a series of operations
indicated by the circles. The products are
manufactured on five machines. The machine
assignments are shown by letters within the
operation circles. The processing time for each
operation is shown in minutes per unit adjacent
to the circle. All setup times are zero. Operation
E is an assembly operation that combines a unit
from each of its two inputs to make the finished
product 2. There are 5000 minutes per week
available on each machine type. There is one of
each type of machine.
a. Use the theory of constraints to identify the
bottlenecks in the system. Show all work used to
find the bottleneck.
b. For the bottlenecks discovered find the best
product mix of P1 and P2. Show in your answer
the rational for selecting the product mix.
c. What is the maximum total profit per week?
