What are GRA+ (Group Role Assignment with Constraints) and GRA++ (GRA with Multiple Objectives)?

GRA+ (Group Role Assignment with Constraints) is an extension of the GRA (Group Role Assignment) method that allows for the inclusion of additional constraints in the optimization problem of collaboration. GRA+ provides a more effective way to investigate multi-player games compared with conventional game theory. It enables researchers to investigate collaboration problems by adding more constraints and making the assignment problem more realistic. The constraints can include, but are not limited to, agent conflicts, role conflicts, conflicts and cooperation among roles and agents, budget restrictions, deadlines, and busyness. These constraints make the problem more complex but also more realistic and closer to real-world situations. By including these constraints, GRA+ opens a brand-new scope for the investigation of assignment problems and provides a more effective way to investigate multi-player games compared with conventional game theory. GRA++ (GRA with Multiple Objectives) extend GRA to include multiple objectives in the problem formulations. GRA++ allows researchers to investigate the trade-offs between different objectives, such as performance and cost, and to find optimal solutions that balance these objectives.
