    The Weinberger Electronics Corporation manufactures four highly technical products that it supplies to aerospace firms that hold NASA contracts. Each of the products must pass through the following departments before they are shipped: wiring, drilling, assembly, and inspection. The time requirement in hours for each unit produced and its corresponding profit value are summarized in the following table:

    Product Wiring Drilling Assembly InspectionUnit Profits
    XJ201 .5 .3 .2 .5 9
    XM897 1.5 1 4 1 12
    TR29 1.5 2 1 .5 15
    BR788 1 3 2 .5 11

    The production available in each department each month, and the minimum monthly production requirement to fulfill the contracts, are as follows:

    Department Capacity Hours Product Minimum Production Level
    Wiring 15,000 XJ201 150
    Drilling 17,000 XM897 100
    Assembly 26,000 TR29 300
    Inspection 12,000 BR788 400

    The production manager has the responsibility of specifying production levels for each product for the coming month. Formulate Weinberger's problem using the computer LP approach.
