) We started a new production process and its study gave the total deviations
The standard value (for 25 samples of the product, sample size 4) is .105
.Calculate the capacity of this process
The product specification limits are: 6.30 = LSL 6.50 = USL
Standard deviation in a manufacturing system is 0.038 =
We made improvements to the system and the deviation has become
Standard 0.030 = σ
What is required is to calculate the estimated coefficient before and after the
operation
Optimization. What is your conclusion?
