A small rm specializes in making ve types of spare automobile parts.
Each part is rst cast from iron in the casting shop and then sent to the nishing
shop where holes are drilled, surfaces are turned, and edges are ground. The
required worker-hours (per 100 units) for each of the parts of the two shops are
shown below:
Part 1 2 3 4 5
Casting 2 1 3 3 1
Finishing 3 2 2 1 1
The pro ts from the parts are 30, 20, 40, 25, and 10 (per 100 units), respec-
tively. The capacities of the casting and nishing shops over the next month are
700 and 1000 worker-hours, respectively. Formulate the problem of determining
the quantities of each spare part to be made during the month so as to maximize
