Answer: 3
Explanation:
Week 1:
Demand forecast = 50 - 49 = 1
Week 2:
Demand forecast = 54 - 51 = 3
Week 3:
Demand forecast = 58 - 57 = 1
Then, MAD = (1+3+1) / 3 = 5/3
Then, tracking signal will be:
= (1+3+1)/5/3
= 5 ÷ 5/3
= 5 × 3/5.
= 3
The tracking signal in week 3 is 3
The tracking signal in week 3 in the historical demand and forecast given above is 3
Week 1: Demand forecast = 50 - 49 = 1
Week 2: Demand forecast = 54 - 51 = 3
Week 3: Demand forecast = 58 - 57 = 1
The mean absolute deviation is given below:
= ( 1 + 3 + 1 ) / 3 ÷ 5/3
= ( 1 + 3 + 1 ) / 5/3
= 5 ÷ 5/3
= 5 × 3/5
= 3
So therefore, the tracking signal in week 3 is 3
The mean absolute deviation it is the average of values.
It is also the difference between actual values and their average value, and is usually used for the calculation of demand variability.
