Question
A company has two CNC machines and it produces four different products. The processing times of the
products differ depending on which machine they are processed. Related information about the products is
shown in the following table.
Processing Time (minutes)
Product

Each product can be produced on either machine A or machine B.
The quantity of product 2 to be produced is related to the quantity of product 3 to be produced. The quantity
of product 2 should be at least two times greater than the quantity of product 3.
The breakdowns occur from time to time and hence machine A is out of order 6% of the time and machine B
8% of the time.
Assuming a working week 35 hours long formulate the problem of how to manufacture these products as a
linear program.
Requirements
a. Define the decision variables clearly.
b. Add a short explanation for each constraint.
