A Distributed Algorithm for Dynamic Break Scheduling in Emergency Service Fleets

The quality of service and efficiency of labour utilization in emergency service fleets, such as police, fire departments, and emergency medical services (EMS), depends, among other things, on the efficiency of work break scheduling. The workload of such fleets usually cannot be forecasted with certainty and its urgency requires an immediate response. However, prolonged focused work periods decrease efficiency with related decline of attention and performance. Therefore, break schedule should be regularly updated as the work shift progresses to allow frequent and sufficiently long time for rest. In this paper, we propose a distributed and dynamic work break scheduling algorithm for crews in emergency service vehicle fleets. Based on the historical intervention data, the algorithm rearranges vehicles’ crews’ work breaks in a manner considering individual crews’ preferences. Moreover, it dynamically reallocates stand-by vehicles for best coverage of a region of interest. We analyze the proposed algorithm and show its performance and efficiency on the EMS use-case.
