A company is involved in the production of two items (X and Y). The resources need to produce X and Y
are twofold, namely machine time for automatic processing and craftsman time for hand finishing. The
table below gives the number of minutes required for each item:
Machine time Craftsman time
Item X 13 20
Item Y 19 29
The company has 40 hours of machine time available in the next working week but only 35 hours of
craftsman time. Machine time is priced at £10 per hour worked and craftsman time is costed at £2 per
hour worked. Both machine and craftsman idle times incur no costs. The revenue received for each item
produced (all production is sold) is £20 for X and £30 for Y. The company has a specific contract to
produce 10 items of X per week for a particular customer.
Formulate the problem of deciding how much to produce per week as a linear program.
