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 studyHow 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.

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.

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 anddo not have access to the tools.
