  • DoE when each run is costly and time consuming ( low throughput process optimization in perfusion bioreactors)

    Hi, I am looking to perform a DoE to optimized process conditions inside a perfusion bioreactor (with yeast). The throughput on the system I am using is essentially 1 and each run would take 1-2 weeks. Because of these constraints I was thinking about performing one run and varying my factors during the run. I can monitor my responses (product titer and cell specific productivity) by sampling and ...

  • How to change the generating rules of screening design

    I am trying to construct a fractional factorial design by the screening design platform，and the design I want to make is a 2（5-1）design with the generator of I=ABCD.this is not a abbreviation design，so I want to change the generator from ABCDE to ABCD.but it looks impossible to generate this design by change the generating rules in screening design platform.if I dont click any of them I get a desi...

  • Help to design a complex DoE on Formulation Buffer Screening

    I'm planning to optimise a formulation for a liquid drug product. We have a starting material that is in a certain buffer with some excipients and would like to find out, if there is even a better formulation buffer for this drug product regarding stability. 
    I want to test:
    - Different pH ranges (pH 5, 6, 7, 8) but the pH levels are set by different buffer systems (pH 5 = acetate buffer, pH 6 = his...

  • Comparision of two DoEs and how to include controls

    Dear JMP-Experts, I created two designs which you find in the attachment. I deleted the DoE dialog scripts cause of data security and provide here only the statistical plan for the experiment. Both are DoE plans with RSM modelling. The Design should be used for optimizing based on existing data.

    Plan1: Here, factor settings for a continuuos and a categorical factor are set. However the categorical ...

  • 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?

    Hello!I installed a script from a community response regarding the calculation of R²pred, as shown in the image below (I'm using JMP 18 pro): (link da resposta do @erich_gundlach https://community.jmp.com/t5/JMP-Add-Ins/Predicted-R-square-calculator/ta-p/39927)  In PRESS, R²pred didn't appear. (Press is low because I haven't reduced the model yet, don't worry =))  I really need to show these R²pre...

  • 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 ...
