9 During the next two months, Machineco must meet (on time) the demands for three types of products shown in Table 45. Two machines are available to produce these This problem is based on Brown, Geoffrion, and Bradley (1981). TABLE 44 products. Machine 1 can only produce products 1 and 2 , and machine 2 can only produce products 2 and 3 . Each machine can be used for up to 40 hours per month. Table 46 shows the time required to produce one unit of each product (independent of the type of machine); the cost of producing one unit of each product on each type of machine; and the cost of holding one unit of each product in inventory for one month. Formulate an MCNFP that could be used to minimize the total cost of meeting all demands on time. TABLE 46 TABLE 45
