Understanding collaboration in sub-structured teams through a computational model of set-based concurrent engineering

Coordinating the collaboration within sub-structured teams created for large engineering projects presents several challenges. Set-based concurrent engineering (SBCE), by maintaining several candidate designs for each subproblem throughout the process, may alter the best ways to coordinate subteams in these projects, compared to point-based concurrent engineering (PBCE) processes in which only one candidate design is maintained for each subproblem. Previous studies have introduced SBCE to industry with positive results and have corroborated its stated benefits through computational study, but researchers have yet to systematically study how SBCE interacts with sub-structured teams. This work augments a multi-agent model developed to simulate and study SBCE, the Point/Set-Organized Research Teams (PSORT) platform, to model sub-structured teams with different forms of intra-subteam collaboration, including joint iteration, design sharing, or no collaboration at all. Design projects are then simulated using these collaboration methods with PBCE and SBCE conditions to investigate how SBCE affects team performance under different modes of intra-subteam collaboration. These studies find that SBCE enables nominal subteams to combine the efforts of multiple designers on individual subproblems with minimal losses, while high levels of collaboration during development are found to assist designers in overcoming design barriers, which SBCE facilitates by maintaining many design options.
