Average Daily Demand

Number of months in the selected time horizon is 1.

Sum of all monthly demands is 300 units.

Number of weeks in the chosen time horizon is 3.

Sum of all weekly demands = 300 + 500 + 450 = 1250 units

Number of days in the chosen time horizon is 5.

Sum of all daily demands = 130 + 240 + 350 + 350 + 300 = 1370 units

(Total demand) = (number of months × sum of all monthly demands) + (number of weeks × sum of all weekly demands) + (number of days × sum of all daily demands)

(Total demand) = (1 × 300) + (3 × 1250) +(5 × 1370) = 10900

(Total number of days) = (number of months × days built per month) + (number of weeks × days build per week) + (number of days)

(Total number of days) = (1 × 20) + (3 ×5) + (5) = 40

(Average daily demand) = (total demand) ÷ (total number of days) = 10900 ÷ 40 = 272.5 units per day
