S

#### senthilgaurav

Hi
Kindly help me to calculate the producer risk,
My Sampling plan is C=0
Lot QTY is 30000
Per Aql 0.65% sampling qty is 77 pcs.
Now want to know about the producer risk in %....

Is this a homework assignment?
What study have you done regarding sampling plans?
What do you think the definition of “producer’s risk” is?

No. Working in a company.
Got a high rejection from customer in a lot
When had argue with customer we had been questioned as what's is ur risk present....so that wanted to know before do back to customer

How many percentage of good parts have to supply is the producer risk if I .not wrong...ease advise..
So gar used 105 E...
If we use the same lot size as 30000..0.65% AQL...sample lot.lot size is 315 ( single sampling plan..normal inspection level II) and c=0 so that the the probability of acceptance is almost 98 %
Because 5/315 ×100 is 1.59 approx this is what I know about AQl so far....but c= 0 did not use yet....this is a first chance for me to use in my present organisation....please help to clear the same

Sorry in 105 E c= 5
can i know the exact:
sample size/lot size: ?
acceptance number: ?
AQL: ?
RQL or LTPD: ?

Thanks a lot for your trying to help me

Lot Size is 30000
AQL0.65%
Under C=0 there is no more Acceptance Number ....
From the chart only can take the sampling qty as 77 pcs

So you're question is the percentage of Producer Risk? or how will you asses the whole lot? is there any RQL or LTPD? 'Cause you can solve this one in MINITAB but i can't solve yet the producer risk, please make it clear for me sir. Please and Thank you!

As our lot quantity is very big our management wants to know if we follow c=0 AQl 0.65% how many % of defective pieces can allow inside the full lot aty...eventhough the sampling inspection passed...like for 30000 pcs take 77 pcs as a sampling qty and did not find any rejected pcs inside this 77 pcs.
