Now the problem says consider the three firms, three firm, supply the chain consisting of the retailer, manufacturing and the supplier.
00:15
The retailer demand for the eight week periods.
00:20
Eight week period, the retailer demand is one one zero units, each of the first two week.
00:31
And 2 to 0 unit, this is for the first two week and 2 to 0 unit for each of the second week.
00:46
Now 310 unit for each of the third week and 410 unit for each of the third week and 410 unit for each of the 4th 2 week.
01:06
The following table present, the order placed by each firm in the supply chain.
01:13
Notice, as is often the case in supply chain due to economics of sales, the total unit are the same in each case.
01:25
But the firms further up, the supply chain place larger, less than the frequency order.
01:32
So we have to solve this problem.
01:35
That is we have to write down the week then the retailer order then the mean how to find out that is x minus mean of x that is of x that is of square now the week one the order is 110 then this value is 23256 .25 .25.
02:29
Now week 2 .2 that is of 110.
02:34
This one also same 23256 point of 25.
02:42
Now week 3 that is of 220.
02:47
Then this value 3 that is of 220.
02:47
Then this value to 1860, 18, this one is 06 of 25.
03:00
And in the fourth week, that is of the 220, that is equal to same, 1806 .25...
