It is to be noted that :
a)Thus:
Workload for period 3 = 400 + 100 + 600 + 300 = 1400
Workload for period 4 = 550 + 800 + 700 = 2050
Workload for period 5 = 200 + 350 + 300 = 850
b)Total operating time for period 3 = 183.6 + 25.6 +486.6 + 108.9 = 804.70 hours
Total operating time for period 4 = 140.2 + 561.6 +386 = 1087.8 hours
Total operating time for period 5 = 34 + 213.9 + 52.2 = 300.1 hours
Total operating hours per machine = 168 hours
It is to be noted that :
Number of machines required for any period
= Total operating time for that period / Operating hours per machine ( rounded to next higher whole number )
Therefore,
Number of machines should be operated for period 3 = 804.70 /168 = .789 ( 5 rounded to next whole number )
Number of machines should be operated for period 4 = 1087.8 /168 = 6.475 ( 7 rounded to next higher whole number)
Number of machines should be operated for period 5 =
Number of machine should be operated for period 3 = 300.10 /168 = 1.78( 2 rounded to next higher whole number)
