“CDP facilitates information exchange, allowing the team to come up with the design of a complex system in a collaborative way”

The design of complex engineering systems requires a multidisciplinary team to share and exchange design information data. While this has been done traditionally with a document-based approach, passing the design from engineer to engineer, concurrent design tools such as the Concurrent Design Platform (CDP) ™ introduce a model-based engineering approach to allow collaborative work in near real time.

First released in 2007, the CDP has facilitated the design of complex systems, from satellites to luxury yachts. Sam Gerene, RHEA Group Senior System Engineer, is a pioneer in the development of concurrent design platforms. He shared his extensive experience with us and talked about the benefits of concurrent design platforms for systems engineering.

How does CDP help streamline the design process of a complex system?
CDP offers a collaborative engineering environment that enables multidisciplinary teams to come up with requirements and find the right solutions for the design of a complex system. It is a platform that facilitates and organizes the exchange of information, allowing the team to come up with the design of a complex system in a collaborative way. Since the engineering information is accessible for the whole team in near real time, it also triggers questions about the design and helps the decision making process. Additionally, it facilitates the creation of concurrent design processes, with all the team gathered in the same room and a team leader orchestrating the process and managing the work.

What are the benefits of using a model-based systems engineering approach as opposed to the document-based approach?
Document-based systems engineering has one main downside: the system information and data is gathered in different documents, and it is difficult to keep up with the different versions. The model-based systems engineering approach expresses and gathers all the information and data related to a specific project in a model. While there are still many companies work with a document-based information exchange methodology, the engineering industry is gradually moving to a more model-based system engineering approach.

Can you name a project that successfully used CDP in their engineering processes?
The European Space Agency (ESA)’s Ariane 6 launcher’s configurations were analyzed with CDP. The Airubs DS team analyzed 21 configurations for the project in six months, as opposed to one configuration in four months in the previous launcher. Airbus DS also used CDP to design the architecture of ESA’s satellite e.deorbit. This was the first time that the client accessed the project’s design data and reviewed the models using CDP.

What’s in store for CDP?
We have just launched a beta version of CDP4 and will launch the full version in 2017. The new version of CDP is compliant with ECSS-TM-10-25A, a standard that describes the concepts needed to design a complex system: parameters, requirements, etc. CDP4 also features a web application.
