Department 3 has 4,500 hours. Transfers are allowed to departments 1 and 4, and from departments 2 and 4. If A, measures the labor hours allocated to department / and 7,, the hours transferred from department / to department j, then O A3 - T23 - T43 + 731 + 734 = 4,500. O T32 + 34 - 13 - 43 + A3 = 4,500. O T23 + 743 - 31 - T34 - A3 = 4,500. O A3 + 23 + 43 - 31 - 734 = 4,500. X
