Two types of printed circuit boards A and B are produced in a computer manufacturing company. The component placement time, soldering time, and inspection time required in producing each unit of A and B are given below. If the amounts of time available per day for component placement, soldering, and inspection are 1500, 1000, and 500 person- minutes, respectively, formulate the optimization problem to determine the number of units A and B to be produced for maximizing the production.
