The J‑CDS Concurrent Design Platform (CDP™) is the main engineering tool to support multidisciplinary teams to perform Concurrent Design in cooperation with and participation of the customer. It provides all the required integrated design and modelling capabilities to support the multidisciplinary team in their collaborative work, allowing them to come up with a solution for the customer, taking into account the full life cycle perspective of the system.

Concurrent Design

Concurrent Design is a systematic approach to integrated product design that emphasises the response to customer expectations and the combination of creativity and engineering. It embodies team values of cooperation, trust and sharing, in such a manner that decision making is by consensus, involving all perspectives in parallel, from the beginning of the product life cycle.

Concurrent Design focuses mainly on the early phases of a project or product, such as preliminary design and feasibility studies. The central principles of Concurrent Design are

• A multidisciplinary team working together to exchange, share and discuss all aspects of a design
• A structured and guided design process
• The presence of the customer providing feedback on the main design and trade-off decisions
• Using one common reference model
• Turning multidisciplinary design sessions into concrete values supported by experts
• Representing all perspectives of the product life cycle

The outcome of Concurrent Design provides management with a very good and complete view of the system/product, thus facilitating their decision-making processes and as such reducing the overall risk of the project from the start.

Concurrent Design has proven to be a powerful design methodology for the early design phases of multidisciplinary projects. It is applicable to a wide variety of projects and industries. Activities have been performed by J‑CDS for complex system design, for Concurrent Design for System-of-System Architectures, for proposal creation, tender evaluation and planning design. One-off projects can be equally well supported as recurring feasibility studies. Multidisciplinary teams have been involved ranging from only customer internal teams to teams involving participants of various independent SMEs, companies and research institutes. Topics are as varied as housing design in the construction sector, medical equipment, small-series electronics and complex satellites within Europe’s leading space companies. The collocated design sessions for projects have been performed in locations ranging from sufficiently equipped meeting rooms to dedicated Concurrent Design facilities.

To implement Concurrent Design in industries as varied as Space, Defence & Security, Oil & Gas Infrastructure & Construction or Electronics, J‑CDS customises the process, the tools and the implementation according to the specific projects or industries.

Overview of the CDP™ capabilities and features

The CDP™ contains the principles of Concurrent Design as an integral part of the tool to reach these objectives.

The CDP™ is used to create an integrated parametric design with supporting calculations specific to the industries standards and data models. The CDP™ is a flexible and reliable tool for the early design phases of projects, focused on allowing a multidisciplinary team to create and share up-to-date design information.

The CDP™ is able to support a design team in the early design phases with the following key capabilities. The CDP™

• Provides a collaborative working environment
• Work compliant with the Concurrent Design methodology
• Provides a clear audit trail in the design process

The CDP™ architecture and features

The CDP™ consists of several components.

The CDP™ Back-End is a structured storage of all the data, providing easy and secure access to data. The Concurrent Design methodology is embedded in the structure of the database.

The information is accessed and managed through the CDP™ Client as main modelling tool. It provides various features and functionalities for administrative actions in a CD activity, e.g. user management, activity management, data exchange control and session management, including session checklists, minutes of meeting and action assignment. Furthermore it supports engineering actions, e.g. setting up and using the design model, tracking parameters and tracing the compliance of the requirements, with the ability to link these to design parameters in the various solution directions.

The team members make use of Microsoft Excel® spread sheets as their engineering work space. These CDP™ Workbooks provide a filtered view on the complete data model in the CDP™ Back-End that allows the engineer to perform design work and calculations within their domain and share that the necessary information with the other team members. This interaction is managed by CDP™ input and output sheets as interface to the CDP™ Back-End. These CDP Workbooks can be customised to include models and calculation sheets for specific disciplines, as well as to provide links between the CDP™ Workbooks and external tools, e.g. other Microsoft Excel® spread sheets, 3D tools such as CATIA, simulation and calculation tools such as Simulink® or MATLAB®.

Additional modules are available integrated into the CDP™ or as self-standing tools with the possibility to interact with the CDP™. The CDP™ Requirements Manager is used to provide traceability of requirements throughout the design activity. Next to the design information in the parametric model itself, the CDP™ has an integrated Document Management System (DMS) to keep track of a wider source of related project information, with possibilities to link these to the actual design model for a better understanding. An example of a self-standing tool is the J‑CDS Stakeholder Value Mapper, to be used for stakeholder analysis in projects. This tool allows to identify stakeholders and their associated goals, values and requirements in a project.

The Concurrent Design Synthesis Dashboard (CDSD™) provides a constant overview to the system engineer and domain engineers in a Concurrent Design activity of the key design information and the status of the process. It combines a set of tools related to the different phases of the CD activity (i.e. initiation, preparation, study, reporting) and visualizes key information. The CDSD ™ consists of 2 main parts, a dashboard view and a toolbox. The CDSD ™ fulfils the need of the team to have an intuitive view of and access to key design information and progress at all times.

The CDP™ Forum provides an additional layer of interaction, giving the team members providing access to the design information from the CDP™ Back-End, see action lists, minutes of meeting and session information as well as providing opportunities to interact in online discussions.

Key technical information

The CDP™ has regular updates, improving the user experience and adding new functionalities based on best practices from industry and user requests.

Client software prerequisites

• Supported operating systems in general: Windows XP, Windows Vista, Windows 7
• Microsoft Office 97-2003, 2007 or 2010 (32-bit version)

The CDP™ server can be hosted by J‑CDS or installed at the customer location. The CDP™ can be set-up to run secure over the internet using SSL.
