(a)
Capacity Cushion = Capacity(Nominal) – Average Demand
Capacity(Nominal) = 18
Average Demand = ((10x.10)+(12x.25)+(14x.30)+(16x.20)+(18x.15) = 14.1
Capacity Cushion = 18 - 14.1
Capacity Cushion = 3.9 million tons
(b)
To get idle capacity= sum for all probabilities where the demand is less than 18 million tons
Idle capacity=0.1 + 0.25 + 0.3 + 0.2
Idle capacity=0.85 or85%
(c)
Utilization = Output/Nominal Capacity
So we get (0.1x10/18)+(0.25x12/18)+(0.3x14/18)+(0.2x16/18)+(0.15x18/18)
Utilization 0.7833333 or 78.33% of average utilization
(d)
Capacity 10mn: (80 x 10) + 8( (12-10x.25)+(14-10x.3)+(16-10x.2)+(18-10x.15) = 832.8
Capacity 12mn: (80 x 12) + 8( (14-12x.3)+(16-12x.2)+(18-12x.15)) = 978.4
Capacity 14mn: (80 x 14) + 8( (16-14x.2)+(18-14x.15)) = 1128
Capacity 16mn: (80 x 16) + 8( (18-16x.15)) = 1282.4
Capacity 18mn: (80 x 18) + 8(0) = 1440
