What is the Standard?There is a response standard STILL on the books todayThe 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
Actual Sectors of Cover for Monterey Fire Dept.
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 EffectivenessRESPONSE 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

MFD Battlefield Setup
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 PLUS a 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
