Hey there, welcome to numerade.
00:03
So we are looking at a forecast smoothing formula here.
00:08
We're giving the customer demand of a particular product across four weeks.
00:13
So we're trying to find what is the value of the exponentially smooth series for the coming week.
00:20
So we're trying to find the forecast value here.
00:24
So in order to find this, the equation we're going to use is f, subscripte, equals.
00:39
So we have our smoothing constant which is denoted as w times a subscript t minus 1, so the previous actual demand here, plus 1 minus the smoothing constant multiplied by f t minus 1.
01:09
So for a forecast of the previous previous demand.
01:16
Okay, so with this here, we know that, let's put this to the left hand side, what we know here is a smoothing constant is given to us a 0 .20.
01:33
And we know our actual previous, to meaning our last recent week is 1024.
01:41
All right.
01:45
So let's plug in the values here.
01:49
F, subscript t...
