Hello student in this question we have to calculate the forecast demand for the week of october 12 so for this we will calculate the weighted moving average okay that is given by sum of weight in period and demand n we can say period n which is divided sum weight weighted moving average okay so we'll put the values now this is 381 into 0 .1 then plus 368 into 0 .3 then plus 374 into 0 .6 over we will take 0 .1 plus 0 .6 so when you will calculate its value is 3 .7 to 9.
01:17
Okay.
01:18
So now we can write that there for forecast october 12 weighted moving average.
01:33
Three weeks moving average.
01:36
Okay.
01:40
That is 373 pinch.
01:48
So this is the final answer for the first part.
01:50
Now solve the second part.
01:53
In this we have to commute the forecast for week october 12 using potential smoothing.
02:02
The ft is equals to ft minus 1 plus a into a t minus 1 then minus ft minus 1.
02:14
Okay? so we'll use this formula here.
02:17
Now firstly forecast for we can say september 7 that is 360 plus 0 .2 into 360 minus 360.
02:33
So its answer is 360 okay now we will calculate the forecast for september 12 that is 360 plus 0 .60 into 389 minus 360 so its answer is 365 .8 so now we'll calculate for september 21 that is 365 .8 plus 0 .2 into 410 minus 365 .8 that is 74 .64 okay now we will calculate for september 28 that is 374 .64 plus 0 .2 into 381 minus 374 .64.
03:31
That is that is 375 .91.
03:36
Now we'll calculate for october 5 then october 12...
