Backstory Monterey Fire Responsiveness on the Monterey Peninsula Road Network
What is the Standard? There is a response standard STILL on the books today The Insurance Services Office (ISO) FD Grading Schedule Fire Stations at 1.5 miles apart
Current Standard • The National Fire Protection Association (NFPA 1710-7, 2010) • The FD shall establish a performance objective of…. • Alarm processing time of 60 seconds (1 min turnover) • 240 seconds for first arriving engine company (4 mins) • 480 seconds for the full alarm assignment (8 mins) • For the achievement of each turnout, not less than 90%.
Monterey Fire Dept. Standards of Coverage Initial apparatus in 6 min (5+1)/80% vs. 5/90%(NFPA) Concentrated Forces 8 min (7+1)/80% vs. 9/90%(NFPA) Time to target time is a better MOE than distance
A few logical questions… • With the assets of the MFD and a given fire • One primary Questions – • What is the Response Time in minutes? • What is the Allocation of Forces? • What if some FSs were unavailable? • How does interdiction impact response time? • Can the system handle simultaneous fires? • Can the Monterey Fire maintain time to target goals with multiple fires?
Measures of Effectiveness RESPONSE TIME • Time required for concentrated forces • Insight for reach within a target time ALLOCATION OF FORCES • Distribution of assets for a given fire demand • Insight on most strained Fire Stations
Monterey Fire Department Assets • Pebble Beach Station1 1 Engine + 1 Ladder • Pebble Beach Station2 1 Engine • Pacific Grove Station 1 Engine • Monterey Station1 1 Engine + 1 Ladder • Monterey Station2 1 Engine • Monterey Station3 1 Engine • Seaside Station 2 Engine • TOTAL 8 Engine + 2 Ladder
Modeling Assumptions • NO distinction between vehicle types • 8 Engine + 2 Ladder = 10 “FireTrucks” • ALL calls are Structural Fires • Demand of 5 “FireTrucks” (Close to reality) • ONLY four fire locations • CHOMP, Aquarium, Wharf, Airport
Graph Representation(Nodes) • Node Selection • Seven Fire Stations • Major road intersections • Center point of Residential Areas • Highly populated fire locations
Graph Representation(Edges) • Edge COST is the time to travel an edge • Time = distance / MPH
Min Cost Max Flow (cost, 0, 1) (8, 0, ∞) FS1 Demand = 5 Supply = -5 s t (0, 5, ∞) (15, 0, ∞) FS2 (cost, 0, 2)

MFD Battlefield Setup xxx 2 1 1 2 1 2 2 1 FireTrucks at FS =
Modeling Interdiction • Degrade the capability of a FS to respond • Remove assets • Less trucks available • Prior tasking
Design of Experiments • All Fire Stations full strength • Fire Station interdiction – 1, 2, 3 • Two simultaneous structural fires • All FS full strength PLUSa new FS with 2 trucks
Conclusions • MFD has a great battlefield setup • MFD can STILL achieve time goals with TWO simultaneous structural fires • This study reinforces the strength of the current system • Functional, resilient and efficient =
Model Improvements • More nodes to better simulate reality • Fire sites • Intersections • Multi-commodity • Timing • Exact fire demand, i.e. 4 Engines, 1 Ladder • Fire demands other than structural • Integration with other FSs, i.e. Carmel, Salinas
