CMDOWS stands for Common Multidisciplinary Design Optimization Workflow Schema. The format has been developed in the framework of the AGILE project (Aircraft 3rd Generation MDO for Innovative Collaboration of Heterogeneous Teams of Experts). For an overview paper on the AGILE project, see reference [1].
CMDOWS is an XML schema that can be used as a standardized format to store the metadata of a collection of disciplinary design tools, such as tool inputs, outputs, execution time, et cetera. CMDOWS is an open-source schema that can be found at http://bitbucket.org/imcovangent/cmdows. More information on the format is provided in reference [2].
A CMDOWS file provides a standardized file that can be used by multiple multidisciplinary design optimization (MDO) support platforms, such as:
The dynamic visualization package has been developed by Benedikt Aigner from the RWTH Aachen's Institute of Aeronautics and Astronautics. It is a package that uses data-driven documents in order to be able to visualize large, complex MDO systems and processes. More information on this package can be found in reference [4].
The graph-based design problem formulation system KADMOS (Knowledge- and graph-based Agile Design for Multidisciplinary Optimization System) can be used to automatically translate a collection of design tools to a design analysis and/or optimization workflow. This package has been developed by Imco van Gent at TU Delft's faculty of Aerospace Engineering. In this website interface, KADMOS is only used to translate the data stored in the CMDOWS file to a format required for the visualization package. More information on KADMOS can be found in reference [5].
CMDOWS file can also be used to automatically create a collaborative PIDO workflow. Within the AGILE project the import of CMDOWS files by two PIDO platforms is under development: RCE by the DLR (German Aerospace Center) and Optimus by Noesis Solutions. More information on the Optimus-CMDOWS interface can be found in reference [6].
