Group role assignment with agents' busyness degrees

Task allocations in collaboration are complex. This paper presents a challenging assignment problem, called Group Role Assignment with Agents' Busyness Degrees (GRAABD). The solution to this problem aims at creating a high-performance group by role assignment with consideration of the busyness degrees of agents. The contribution of this paper is the formalization of the proposed problem, a practical solution that uses the Group Role Assignment (GRA) algorithm, and a verification of the benefits of solving the GRAABD problem by simulations. Finally, a better solution to GRAABD, i.e., GRAABD-Syn is proposed, when the busyness' impacts on personal qualifications are considered.
