EVI - Evacuation Analysis Software

Advanced Modelling

EVI is a computer based pedestrian and crowd simulation tool that can represent many individuals and assesses their behaviour and interaction with the surrounding environment, such as on a ship or in a building. EVI can be used throughout the design process to optimise designs at an early stage to ensure safe and efficient evacuation, thereby avoiding costly redesign.

EVI has been used on over 40 vessel designs to demonstrate they meet the latest IMO requirements for evacuation and on cruise terminal buildings and embarkation arrangements to visualise passenger flow and estimate passenger turnaround times.

EVI’s ease of use allows 3D environments, individuals and assembly stations to be quickly modelled so that simple evacuation scenarios can be set up and solved within minutes.

Complex layouts and scenarios can be developed by using EVI’s in built commands and scripting capabilities, making EVI a powerful analysis and simulation tool. Routing of individuals can be achieved through definition of primary or secondary routes, one way or blocked doors or confinement to within certain areas, such as fire zones.

EVI can import fire data, such as visibility, air quality (CO/CO2 levels) and temperature from Fire Dynamic Simulator (FDS) software to simulate smoke and toxic atmospheres and the impact this has on individuals. By incorporating this data into the simulation, it is possible to visualise the individuals that become incapacitated and locations that are untenable once critical thresholds are exceeded. The software provides time histories for incapacitated individuals and allows easy comparison of the Required and Available Safe Egress Times (RSET and ASET).

For ship evacuation, static or progressive flooding damage can be modelled through user input of a heel angle or through a dedicated data link with Brookes Bell’s PROTEUS software. Brookes Bell’s PROTEUS software is used to simulate real time progressive flooding of water through affected compartments and their openings.

Sophisticated Behavioural Models

EVI incorporates a sophisticated multi level behaviour model which allows individuals to perform high level path planning and be set objectives (Macroscopic behaviour). Whilst traversing a path and meeting objectives, individuals interact with one another and the surrounding environment (Microscopic behaviour).

Individuals can be set specific tasks such as space searches to clear rooms or message passing for guidance or re-routing. Demographics such as speed, response time, age and gender can also be set to mimic the range of individuals included in the simulations.

Powerful and Flexible Evacuation Analysis Software

EVI's range of capabilities provide the flexibility to ensure that it can be used for a wide variety of tasks, such as:

  • Advanced evacuation analysis of passenger ships for compliance with IMO MSC.1/Circ. 1533 (previously MSC.1/Circ.1238).
  • Building evacuation analysis for compliance with Building Regulations 2010 and the Regulatory Reform Fire Safety Order 2005.
  • Performance based design assessment of alternative design arrangements (ADA) through comparison with designs base on statutory requirements.
  • Assessment of turnaround times for passenger ship terminals.
  • Escape, Evacuation and Rescue Assessments (EERA) for offshore installations or special purpose ships.
  • Simulation of emergency evacuation procedures for Muster List development and crew training.

Application Features

Quick, Efficient Modelling

CAD files can be used to build accurate models within minutes

Real-time Simulation

Real-time simulation and a 3-D interactive graphical user interface allows for play-back and analysis of different scenarios.

Customisable Reporting

EVI is capable of generating standard and can be tailored to provide specific reports.

Commands and Scripting

Commands and scripting capabilities allow for the modelling of complex scenarios, e.g. validation of Muster List and crew procedures).

Handle Uncertainty

Explicit handling of uncertainty using the Monte-Carlo simulation approach allows for the inclusion of factors such as occupants' demographics (e.g walking speed).

Fire and Flooding Simulation

EVI can be linked with fire and flooding simulation software to undertake direct assessment of the impact of smoke and flooding on escape/evacuation performance.
