Determine how many
emergency resources
that requires in a given
area.
Where stations and
resources should be
located.

Introduction

How resources should be
relocated depending on
the current situation. To maintain a good level
of preparedness in the
area.

Introduction
Anna Gustafsson, ITN LiU
The response time is one of
the most important factors in
the rescue effort.
An adequate location can
reduce the response time!

Research project 1
Case study
How fire and rescue resources should be located to meet the
demand in Östergötland County in Sweden.
To minimize the response time to building fires and traffic
accidents.
Developed a model to locate three types of resources,
manned differently.

Research project 1
Solutions have been produced for a number of different
scenarios using variable neighborhood search heuristic.
By optimizing the locations for fire and rescue resources, the
response time can be reduced with around 20 %.
The mean response times for first responses and full responses
are reduced by around 100 to 150 seconds in the optimized
solutions.

Research project 2
DYRK
Explore the potential of working more dynamically with planning
and management of emergency resources.
It is about planning, controlling and making decisions about
managing emergency resources depending on the current situation.
The need for assistance varies during the day – resources are not
optimally located all the times.
The resources are not always at the station.
If a station’s resources are occupied, the preparedness will decrease in
the area around the station.

Describes the ability to respond to accidents in the present and
in the future.

Preparedness
Describes the ability to respond to accidents in the present and
in the future.
What we have What we need
We have developed a quantitative measure for preparedness
To determine specific preparedness for handling a certain type of
incident.
A basis for decision making and planning.

16
Preparedness
Anna Gustafsson, ITN LiU
The goal is to constantly
maintain a good
preparedness in the area.
Important that resources
arrive quickly in
emergency situations.
Right type of resources
Adequate staffing
Dynamic use of the
resources!
17
Research project 2
Develop decision support tools that can support dynamic
planning of fire and rescue services.
Calculate the preparedness and show how it change when specific
resources are moved.
Propose which resources that should be dispatched to a specific
incident according to the alarm plan.
Give suggestions about how resources should be located and
relocated.

Research project 2
Collaborating with fire and rescue services in Sweden
Test the developed tools
Fire and rescue services in Sweden will perform a series of test
scenario.
The tests will compare situations
when the decision maker have and
do not have access to the tools.
