This event was created by the French Center of Excellence on Systems Architecture, Management, Economy & Strategy (CESAMES) which already organized the now well established CSD&M conference in Europe for more than 6 years. The core principles that lead to the success of these conferences are also put at the heart of CSD&M , seeking a balance between academia, government and industry partners. Indeed, we believe that mastering complexity can only be achieved with a strong and true cooperation between all key stakeholders. We look very much forward to the participation of the complex systems community to this upcoming seventh edition of CSD&M.
