  • Mixture design with special constraints

    Good morning,

    The aim is to test mixtures of components to target a continuous variable Z.

    To achieve this, the blend must contain one (and only one) component from each of the following familly (these categories are made up of components with similar characteristics), plus glycerine (systematically):
    Family 1: A, B
    Family 2: C, D
    Family 3: E, F, G, H, I, J
    Family 4: glycerine

    Two intermediate continuous...

  • Inquiry about Experimental Design with JMP

    Hello,
    I have a concern. I am a beginner in experimental design, and I am conducting formulation trials for medicines.To start, I screened a number of factors and variables to narrow down the factors for my experimental design.I would now like to optimize. The parameters are as follows:3 responses: Y1, Y2, Y34 factors, of which 3 are continuous (each with 3 levels), and 1 is categorical with 2 leve...

  • Response Surface Design with continous factors and one categorical factor

    Hello Fellow JMPers' I am trying to find the optimum manufacturing parameters using the RSM approach. My design has 5 responses and 5 factors ( 4 continuous and 1 categorical).  I tried using the DOE- Classical- Response Surface Design; but when I get to inputting the factors, it seems the factors can only be continuous? I was using the CCD design. I am not sure how I can navigate this. When I go ...

  • Extend a DOE with new discrete numeric values

    Hi, I have performed a DoE on a chemical reaction with four parameters, three with four discrete numeric values and one constant. The DoE gave me some useful insight and I now want to extend the DoE but limit the values of my discrete parameters and change my constant value to a continuous. I've watched many of your YouTube videos and searched the discussions here without luck. I found that my low...

  • How to evaluate Alias structures in D-optimal DOE?

    My understanding is that D-optimal designs can be good for screening experiments, but you'd better hope there aren't any large interaction effects, otherwise they will bias your main effects, or that you should add some suspected 2-way interactions to your optimal design as a way to avoid aliasing effects.  I've been told to avoid Res III fractional factorials, & Plackett-Burman designs for screen...

  • Sample size for Reliability Life Test

    I have used the interval explorer for parametric reliability life test planning for sample size calculation of accelerated life test. Please can someone confirm if the sample size returned is the total sample size or sample size per stress levels? Assuming I have 3 temperature levels, do I use 75 samples per temperature level or 25?

  • Sample size calculation for accelerated life testing

    I am trying to use the interval explorer for parametric reliability life test planning tool for sample size required for an ALT test but need some clarification on the following questions.         1. Is the Weibull alpha the characteristic life at stress or at use life? 2. Is the Quantile the pFail at stress or use life and how does the quantile impact the required sample size?3. Is the calculated...

  • How do I replace a prediction expression in a fit model with a specific expression?

    Hi, I am completing a DOE and I have ran a fit model using the JMP software to define a design space based on desirability of certain variables, however one of the desirability variables is a simple ratio of two of the construct model effects, however when running the model, the model is defining its own prediction expression for this variable rather than using the formula in the data table. Does ...

    I read the JMP help book and understand how combined rule applied to p-value based stepwise regression (a joint F-test and another partial F-test of interaction effect when added precedent main effects). ...
