We have developed a system to assist first responders called COORDINATORs. COORDINATORs are coordination managers for fielded first responders and their commanders that provide decision support to the first response teams, assisting them in reasoning about who should be doing what, when, and with what resources. Building on our existing COORDINATORs system, much exciting work remains to enable them to adapt to dynamic, large-scale crises. These crises are characterized by multi-point concurrent incidents spread across large geographic areas where multiple organizations or teams are responding. We discuss our ongoing efforts to improve the capabilities of COORDINATORs through improved human-computer interfaces and more flexible optimization models.
