i m facing a problem regarding surface plot and d optimality.earilier we had set our injection mouldingg parameter with the help of hit and trail.now i want to go for six sigma project to find out optimum value that may or may not be different from earlier settinf of parameters.so i have find out three levels (low high and medium ) of all crtical parameters with the help of regression analysis. now my problem is that as i m dealing with continous varibles so i can not go for simple mail effect plot so i decided to go for surface plot . but i do not know how to find out optimum setting and what is d optimality.and my response is also attributes like defective or non defective. so please suggest me how to collect response at different setting of parameters. if i go by attribute response will it create problem in response plot or not.

process improvement0August 9, 2005 at 8:36 am #124588Rajesh,Prior to using any optimality function you should perform a model reduction using the ANOVA table that resulted from the initial DOE analysis. This ANOVA table should include interactions, and allow you to determine which effects, main and interaction are significant. Concerning the attribute response data. Consider doing an intial piecewise analysis to see which inputs affect each response. If your lucky, both responses will be affected by similar inputs. If not, you will need to evaluate the effect on the response of changing non-significant inputs for example the continuous response vs. significant inputs for the attribute response.Good luck,Ken
