This work describes a novel approach to the problem of workforce distribution in dynamic multi-agent systems based on blackboard architectures, focusing especially on a real-world scenario: the multi-skill call centre. Traditionally, to address such highly-dynamic environments, diverse greedy heuristics have been applied to provide solutions in real-time. Basically, these heuristics perform a continuous re-planning on the system, taking into account its current state at all times. As decisions are greedily taken, the distribution of the workforce may be poor in the medium and/or long term....
