  • デザインスペースの領域が一致しません。

    JMPの練習のため、論文のデータを用いて解析・再現をしています。 その中で3つの不純物に対してPlackett-Burman計画によるスクリーニング・中心複合計画による最適化を実施し、予測モデルを作成しました。 論文中に記載されている予測モデル式はいずれも同様のものが作成できました。   論文中では最適化の過程でプーリングをしていますが、モデルを合わせたデザインスペース作成のため、すべてのパラメーターを含むモデルを使用したと記載があります。 これに従い、プーリングしない状態、すなわちすべてのパラメーターを含む状態で予測モデル式を作成し、デザインスペースを作りました。   しかし、不純物が0.1%以上となるデザインスペースのエリアが一致せず、私の作成したものの方が広くなっています。 デザインスペース作成に用いた予測モデルの式は記載がないため不明ですが、原因はどこにあるのでしょうか。   つた...

  • How to analyze impact of responses (e.g. PSD) on product performance in spray drying process in JMP

    I am working on a spray drying process and have used CCD design with D10, D50, and D90 as responses. However, its dissolution profile and its flowability are dependent on the size distribution of the powder (D10, D50, and D90). What is the best way to analyze the effect of the responses (particle size) on the product performance (dissolution and flowability) given that the size distribution values...

  • Mixture design with 11 ingredients, including 4 under study

    Hello everyone, Not having found a similar case on the forum, I am seeking your help and opinions regarding my mixture design. I aim to maximize the stability duration of a formula containing 11 ingredients, 4 of which (X1 to X4) I want to vary and study. - X1 between 1 and 4%
    - X2 between 3 and 8%
    - X3 between 7 and 12%
    - X4 between 0.4 and 0.8%
    - X5 = 4%
    - X6 = 2%
    - X7 = 1%
    - X8 = 2%
    - X9 = 0.5%...

  • Correcting Discrete Numeric Factor Level Discrepencies in DOE Model

    Hello to anyone reading this post. I hope you're having a great day!   Question Context: I am a junior engineering student and have built DOE with 3 discrete numerical factors at two levels and one response and then conducted trials. Then with JmpPro will use linear regression to develop a model including all interactions for my results. (This is the assignment) However there was an issue during d...

  • Space Filling Design - Fast Flexible Filling

    I applied a couple constraints when running a Space Filling DOE and it performed pretty well. However, the algorithm "Fast Flexible Filling" is a bit cryptic. Where can I find documentation that expounds on the algorithm/methods behind "Fast Flexible Filling"?   JMP Ver.18.0.1

  • Design space regions do not match.

    To practice using JMP, I am analyzing and reproducing data from papers. Among these, screening using the Plackett-Burman design and optimization using the central composite design were performed for three impurities to create a predictive model. Similar predictive model equations were created for all of the models described in the paper.   The paper states that pooling was performed during the opt...

  • Predicted values for conversion over 100%.

    Hello everyone, I’m running a Central Composite Rotatable Design (CCRD) in JMP to optimize a chemical reaction, with conversion (%) as my response variable. By definition, conversion should range from 0% to 100%. However, my fitted model sometimes predicts conversion values greater than 100% (and occasionally less than 0%) for certain factor combinations. Here’s what I’ve done so far: My experime...

  • 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 ...
