“…CE shares a technical perspective with co-design as an integrated method to coordinate design activities to achieve holistic objectives but also includes disciplinary human actors inside the system boundary (Holt & Barnes 2010). CE broadly encompasses the team (people), model (shared knowledge), tools, process and facility for a design activity (Knoll, Fortin & Golkar 2018). Alternative CE strategies seek either to decouple tasks to reduce time or increase coupling between tasks to improve quality (Eppinger 1991).…”

This paper draws on perspectives from co-design as an integrative and collaborative design activity and co-simulation as a supporting information system to advance engineering design methods for problems of societal significance. Design and implementation of the Sustainable Infrastructure Planning Game provides a prototypical co-design artifact that leverages the High Level Architecture co-simulation standard. Three role players create a strategic infrastructure plan for agricultural, water and energy sectors to meet sustainability objectives for a growing and urbaninzing population in a fictional desert nation. An observational study conducts 15 co-design sessions to understand underlying dynamics between actors and how co-simulation capabilities influence design outcomes. Results characterize the dependencies and conflicts between player roles based on technical exchange of resource flows, identifying tension between agriculture and water roles based on water demands for irrigation. Analysis shows a correlation between data exchange, facilitated by synchronous co-simulation, and highly ranked achievement of joint sustainability outcomes. Conclusions reflect on the opportunities and challenges presented by co-simulation in co-design settings to address engineering systems problems.

“…As a consequence, frequently there are people on the team who are new to CCD 9 . The concurrent design process and the relative tools require training, which in most organizations is provided on‐the‐go 8 . Moreover, our survey shows that some organizations struggle to find enough people with the appropriate engineering expertise and familiarity with CCD 8 .…”

This work presents a model of the process of conceptual design studies which use the concurrent engineering approach. Concurrent conceptual design is an integrated system development approach, to rapidly explore feasible design solutions by parallelizing the work of experts. This approach is characterized by a multidisciplinary team of experts collaborating in a co‐located manner. Albeit the conceptual design phase requires creative problem solving, teamwork requires coordination, and would profit from a shared understanding of the design process. Based on a survey among experts from 15 different organizations, and practice documented in literature, we propose a model of the underlying design process. This work extends our previous work on a coordination method for concurrent design and provides validation of the process model via case studies and expert interviews. The proposed process model is formalized in SysML diagrams. It can be used to help program coordinators and train engineers of different disciplines on the methodology of concurrent conceptual design, as well to serve as a baseline for implementing the methodology in new organizations.

Conceptual‐Design is an early development phase, where innovation and creativeness shape the future system/product. Model‐Based‐Conceptual‐Design (MBCD) attempts to use best‐practices of Model‐Based‐Systems‐Engineering (MBSE) to gain the envisioned benefits of model connectivity. Using MBSE supporting tools can transform Conceptual‐Design into a digital‐engineered process but may impede creativity and innovation. Concurrently, the design domain offers specific methods and tools for innovative Conceptual‐Design. In the current study, we explore an existing Conceptual‐Design framework and offer MBSE interpretation and tools extensions needed for its digital implementation. Through such exploration we highlight MBCD specific insights and discuss modeling‐innovation interrelations. The implementation was accomplished using a domain‐specific enabling software package on top of a market‐accepted UML/SysML platform, extending the language definitions, where appropriate. The framework guided extensions allow generation of innovative bottom‐up alternatives, solution integration, and solutions’ comparison. The use of modeling is shown to offer clearer process definition, specific methods assistance, and alternative ranking—both manually and automatically. Consequently, MBCD is accomplished, which supports innovation, while being digitally connected to full‐scale‐development models and the organizational assets at large. Through integration into the orderly Systems‐Engineering process, traceability is maintained, and repeated iterations are supported, where conceptual decisions may be revisited. Additionally, through the introduction of an assets’ catalog, cross‐organizational knowledge sharing is accomplished. The paper presents samples of the extensions, using a simplified example of technology design for Future Firefighting. The value of incorporating Conceptual‐Design specific methodology and tools is evaluated through feedback from multiple domain experts. Discussion and future research directions are offered.
