Summary:

DOE: Design an experiment, fit a model to experimental data, and find best factor settings that optimize responses.

Screen Shot and Video:
Description:

Purpose

This DOE app helps you determine the relationship between factors affecting a process and the output of that process.

You can use it to design an experiment, analyze experimental data and optimize output.

Features

  • Various types of designed experiments to help you create a design.
  • Customization of design table by replication, randomization, blocking, etc.
  • Fit of mathematical model to data from test runs.
  • Diagnostic statistics and graphs to help you interpret the results.
  • Optimization of response after defining factor constraints.

      Updates since OriginPro 2024:

  • Support available design for 2-level factorial and central composite design (with default parameters).
  • Save and load design parameters for Power and Sample Size and Create Design.

       Please read this blog to learn the updates.

 

Installation

The app requires R software (minimum required version 3.4.1) and packages (rsm, FrF2, alr3, qpcR).

For Origin version older than 2020b:

  1. Install R or upgrade it before installing the App (download R from here).
  2. Download the file DOE.opx, and drag-and-drop the file onto Origin workspace to install the App.
  3. The App will start downloading dependent R packages. Wait a few minutes until it is completed.

For Origin 2020b and later versions:

  1. Run Origin as administrator. Download the file DOE.opx and install it by choosing Tools->Package Manager->Tools->Install a Package.
  2. After App installation, a pop-up dialog will ask if you agree to download and install R software before it proceeds. (If automatic downloading fails, you can install the App again or download R from here.)
  3. For the first time you launch the App, it will start downloading dependent R packages. Wait a few minutes until it is completed.

Note: If downloading packages fails, a pop-up dialog will ask you to copy 2 lines of commands from Results Log and run them in R to complete downloading packages. 
          If you reinstall or upgrade R after installing the app, it would not work properly. Please reinstall the app.

Operation

Click the app icon to open the dialog with 4 buttons. Click one of them to open a dialog. 

  • Power and Sample Size

    Determine sample sizes before creating a design. Calculate power for a given sample size or sample sizes for given power values.

  • Create Design

    Identify factors and levels for each factor. Use techniques of the design to create a design table that makes the experiment cost-effective. Conduct a series of experiments and collect response data for each run in the table. The following types of design are supported.

    • Factorial Design
      • 2-Level Factorial
      • Plackett-Burman
      • General Full Factorial
    • Response Surface Design
      • Central Composite
      • Box-Behnken
  • Analyze Design

    Fit a model to data collected using the design. Evaluate which factors have a significant impact on the response. You can interpret the relationship between factors and response through a variety of analytical tools and graph tools.

  • Optimize Response

    Determine what levels of factors should be to achieve a desired response. You can choose goals like minimize, maximize and target to optimize. Put constraints on factor levels before optimization.

Help File

This app provides a help file that introduces design of experiments and explains dialog settings. Click ? button in dialog or press F1 to open it.

Sample OPJU File

This app provides a sample OPJU file and a data file. Right click on the app icon in the Apps Gallery window, and choose Show Samples Folder from the short-cut menu. A folder will open. Drag-and-drop the project file DOE Sample.opju from the folder onto Origin. The Notes window in the project shows detailed steps.
Note: If you wish to save the OPJU after changing, it is recommended that you save to a different folder location (e.g. User Files Folder).

Could you please submit a new ticket, and send us the opju file you are working on and the steps to reproduce the issue via the ticket: https://www.originlab.com/restricted/support/newticket.aspx?c=3

04/24/2022 always resulting an error leading to closing the program, while trying to analyze the results

02/18/2022yukiOriginlabHi Archit_iitd,
You can construct the equation based on the coded coefficients table of the report sheet by yourself. The coded coefficients should multiply coded factor levels(-1 or 1) when you calculate the fitted values.
If you have any more suggestions to show the equation better, please submit a ticket and tell us more details: https://www.originlab.com/restricted/support/newticket.aspx?c=3

02/18/2022Archit_iitdI am not able to get the Regression equation of the fitted data points from the design of experiment analysis. Kindly Let me know if it is available somewhere.

03/03/2021yukiOriginlabHi glarteyyoung,
Could you try to open R console via menu Connectivity: R console? If you fail to open this, you can try to fix as this quick help:

03/03/2021glarteyyoungGreat tool. but still ask to intall R software.

03/03/2021glarteyyoungwhy does it still ask you to install R software, eventhough its already installed
