The XDSM (eXtended Design Structure Matrix) is a notation used to visualize MDO processes. It was developed by A. B. Lambe and J. R. R. A. Martins, see MDOLab website dedicated page.

XDSM permissions:

If you use the XDSM format for research, we ask that you cite the following journal publication in your work: A. B. Lambe and J. R. R. A. Martins, “Extensions to the Design Structure Matrix for the Description of Multidisciplinary Design, Analysis, and Optimization Processes”, Structural and Multidisciplinary Optimization, vol. 46, no. 2, p. 273-284, 2012.


XDSMjs is a javascript generator allowing to display a XDSM diagram within a web page. It is based on D3. It uses the xdsm.json file as input which contains required MDO information to generate the XDSM diagram. See the dedicated Wiki page for a description of the XDSMjs JSON format.

As of 0.6.0, the MDO data can be specified through data attribute.

As of 0.7.0, XDSMjs supports also XDSM v2. See Upgrade to 0.7.0 notes.


If you happen to find XDSMjs useful for research and include diagrams generated with it, it will be appreciated if you cite the paper which describes the WhatsOpt project that led to XDSMjs development


> cd <install-dir>/XDSMjs
> python -m http.server 8020

Open http://localhost:8020/xdsm.html in the browser.

To see other diagrams, copy a json example from examples directory as xdsm.json and reload the page.

As of 0.6.0 version, to use XDSMjs in your web page, you can :

  • include the following declarations in your header :
  <link rel="stylesheet" href="xdsmjs.css">
  <script type="text/javascript" src="dist/xdsmjs.js"></script>
  • add the place-holder div element that will contain the XDSM diagram :
  <div class="xdsm"></div>

You can either use the attribute data-mdo to specify MDO data in the XDSMjs JSON format in an HTML escaped string

  <div class="xdsm" data-mdo="{&quot;root&quot;: {&quot;nodes&quot;: [...], &quot;edges&quot;: [...], ... }}"></div>

or use the attribute data-mdo-file to specify another MDO filename

  <div class="xdsm" data-mdo-file="examples/mdf.json"></div>

If no data attribute is specified, the default file xdsm.json is expected.

As of 0.7.0, you can use XDSM v2 notation by using xdsm2 class instead of xdsm.

  <div class="xdsm2"></div>

As of 0.8.0, you can specify configuration and MDO data directly from the <script> element in the html file.

    <script type="text/javascript">
        document.addEventListener('DOMContentLoaded', () => {
            let mdo = {nodes: ..., edges: ...}
            let config = { labelizer: { showNbLinkOnly: true } };


Below an example describing BLISS formulation inspired from XDSM description given in Martins and Lambe MDO architecture survey. While the formulation could have been described in one diagram as in the survey, the example below use XDSMjs multi-level diagram capability to separate system and discipline optimization levels. The corresponding xdsm.json file is available in the example directory.
