Introduction


Determine how many

emergency resources

that requires in a given

area.

Where stations and

resources should be

located.

4

Introduction


How many and what type

of resources should be

sent to a particular

incident?

5

Introduction


How many and what type

of resources should be

sent to a particular

incident?

6

Introduction


How resources should be

relocated depending on

the current situation. To maintain a good level

of preparedness in the

area.

7

Introduction


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.

Preparedness

Describes the ability to respond to accidents in the present and

in the future.

What we have What we need


15

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


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.


18

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.
