Why This Matters

Emergency response systems must make decisions about resource allocation in real-time with incomplete information about incident severity and responder availability. Traditional approaches often focus on minimizing response time for individual incidents without considering overall system efficiency or the need to dynamically rebalance resources. This work is innovative because it provides algorithmic approaches for emergency response that optimize over multiple objectives and adapt dynamically to changing incident patterns, enabling more efficient and effective emergency management.

What We Did

This paper presents algorithmic decision procedures for emergency response management in smart cities, addressing the problem of optimal incident response under constraints of limited resources and communication disruptions. The work develops both greedy and Monte Carlo Tree Search approaches for dynamically rebalancing emergency responders in response to changing incident patterns. The methodology addresses the tension between minimizing immediate response times and maintaining overall system efficiency.

Key Results

The algorithmic approaches successfully identify optimal responder allocations and demonstrate that dynamic rebalancing strategies can significantly reduce average response times compared to greedy approaches. Monte Carlo Tree Search provides more sophisticated decision-making by considering future incident probabilities, while greedy approaches offer computational efficiency. Results show that the approach enables emergency response systems to balance immediate response needs with longer-term system efficiency.

  abstract = {Emergency Response Management (ERM) is a critical problem faced by communities across the globe. Despite its importance, it is common for ERM systems to follow myopic and straight-forward decision policies in the real world. Principled approaches to aid decision-making under uncertainty have been explored in this context but have failed to be accepted into real systems. We identify a key issue impeding their adoption --- algorithmic approaches to emergency response focus on reactive, post-incident dispatching actions, i.e. optimally dispatching a responder after incidents occur. However, the critical nature of emergency response dictates that when an incident occurs, first responders always dispatch the closest available responder to the incident. We argue that the crucial period of planning for ERM systems is not post-incident, but between incidents. However, this is not a trivial planning problem -  a major challenge with dynamically balancing the spatial distribution of responders is the complexity of the problem. An orthogonal problem in ERM systems is to plan under limited communication, which is particularly important in disaster scenarios that affect communication networks. We address both the problems by proposing two partially decentralized multi-agent planning algorithms that utilize heuristics and the structure of the dispatch problem.  We evaluate our proposed approach using real-world data, and find that in several contexts, dynamic re-balancing the spatial distribution of emergency responders reduces both the average response time as well as its variance. },
