Question:
Should the company continue producing aluminum rods or buy parts from outside suppliers? You have been asked to lead a problem-solving team and recommend a solution. Hint:
You must run the following analysis, study results and make a recommendation:
· Run a normality test for the machine shop and each supplier A, B and C data set
· Perform a Process Capability Analysis for the machine shop, supplier A, B, and C
· Approximate Sigma level for the machine shop, supplier A, B and C (Use
Cpks)
· Calculate Cp to determine how much the machine shop and each supplier (A, B and C) sample is consuming out of the spec.
· Scrap cost for the machine shop and each supplier A, B and C (Use Taguchi analysis)
|
· Run ¯¯ and R chart for the machine shop, supplier A, B, and C
