Question: Each day, workers at MI6 (A security service provider) work two 4-hour shifts chosen from 12 A.M. to 4 A.M., 4 A.M. to 8 A.M.,
Each day, workers at MI6 (A secunity service provider) work two 4-hour shifts chosen from 12 A.M. to 4 A.M., 4 A.M. to 8 A.M., 8 A.M. to 12 P.M., 12 P.M. to 4 P.M., 4 P.M. to 8 P.M. and 8 P.M. to 12 A.M. The following number of workers are needed during each shift: 12 A.M. to 4 A.M. - 28 workers; 4 A.M. to 8 A.M. - 16 workers, 8 A.M. to 12 P.M. - 10 workers, 12 P.M. to 4 P.M. - 8 workers; 4 P.M. to 8 P.M. -12 workers; 8 P.M. to 12 A.M. -35 workers. Workers whose two shifts are consecutive are paid R100 per hour; workers whose shifts are not consecutive are paid R135 per hour. Formulate a Linear Programming (LP) model that can be used to minimize the cost of meeting the daily workforce demands of MI6
