请教MSA的概念问题
今天看到客户给的GRR的报告样本中有如下三个指标：
1 %contribution 2 %study var 3 %tolerance var
请问这三个指标都代表什么？一般它们的大小关系应是如何的？一般如何判定？
在此先谢谢各位大侠了！

According to the Automobile Industry Action Group (AIAG) , you can determine whether your measurement system is acceptable using the following guidelines.
If the Total Gage R&R contribution in the %Study Var column (% Tolerance, %Process) is:
· Less than 10% - the measurement system is acceptable.
· Between 10% and 30% - the measurement system is acceptable depending on the application, the cost of the measuring device, cost of repair, or other factors.
· Greater than 30% - the measurement system is unacceptable and should be improved.
If you are looking at the %Contribution column, the corresponding standards are:
· Less than 1% - the measurement system is acceptable.
· Between 1% and 9% - the measurement system is acceptable depending on the application, the cost of the measuring device, cost of repair, or other factors.
· Greater than 9% - the measurement system is unacceptable and should be improved.
仔细看完这段话，就知道怎么判断了。
10～30％是Total的，不过下面还有分支，也需要查看是否在范围内
1～9％也是相同的道理。
通过楼上几位的详细分析与补充，已经比较清晰了。
不过，如果二楼的能够得出分析的结论的详细解说就更加完善了。
