Brand spanking new to the forum. Registered just to ask this question... We have a machine at work that has the following parameters: tempurature pressure time This machine machine processes a prodcut that has two properties: quantity stiffnes shade (Not really sure if the shade actually changes the process properties but thought I'd add it) My question is whether it's possible to create an adustment matrix encompassing the three machine variables and 3 product properties, to improve first-time-right process adjustments by machine operators? I'm sure there is a way, but my skills in this area are exceedinly low. I'm more than willing to research possible methods (registered for this forum for starters) I just need a jumping off point, or a nudge in the right direction. Oh, and probably about 3 more years of calculus sprinkled with a little advanced statistics. But a nudge will get me started :) Thanks, to anyone who chimes in on this.
