Sterling Industries Ltd. manufactures product Z by making and assembling three components, A, B and C. The components are made in a machine shop using three identical machines each of which can make any of the three components. However, the total capacity of the three machines is only 12, 000 machine hours per month and is just sufficient to meet the current demand. Labour for assembling is available according to requirements. Further details are given below.
