The learning factory palmer ma3/20/2023 ![]() In the design of a spacecraft, for example, experts in propulsion, computer science, power systems, and many other areas must work together to create a working design (Kroo et al., Reference Kroo, Altus, Braun, Gage and Sobiesky1994). Often this involves coordinating specialists from the relevant disciplines. When designing a complex engineered system with a number of different analyses and concerns, engineers must take into account the many interactions between subsystems in order to optimize the performance of the design. The design of complex engineered systems provides a significant challenge to engineering organizations. This multiagent system is further shown to produce better-performing designs when computational designers design collaboratively as opposed to independently, confirming the importance of collaboration in complex systems design. When used as a model, this multiagent system is shown to perform better when the level of designer exploration is not decayed but is instead controlled based on the increase of design knowledge, suggesting that designers in multidisciplinary teams should not simply reduce the scope of design exploration over time, but should adapt based on changes in their collective knowledge of the design space. These designers are represented as a multiagent learning system which is shown to perform similarly to a centralized optimization algorithm on the same domain. This paper presents a new model which captures the distributed nature of complex systems design by decomposing the ability to control design variables to individual computational designers acting on a problem with shared constraints. Current multiagent models of design teams, however, do not capture this distributed aspect of design teams – instead either representing designers as agents which control all variables, measuring organizational outcomes instead of design outcomes, or representing different aspects of distributed design, such as negotiation. ![]() This situation is analogous to a multiagent system in which agents solve individual parts of a larger problem in a coordinated way. ![]() To design a system, experts from the relevant disciplines must work together to create the best overall system from their individual components. Complex engineered systems design is a collaborative activity. ![]()
