Three Ways To Use VISACA. View library facilities and their pre-calculated

grids of blast points use viewers to explore geometry and logic search grids for specific outcomes

B. Run “what-if?” scenarios using different attacks on the library facilities accidents, component damage, blasts find release probabilities, facility kill &

downtime

C. Create a new facility based on the library facilities and create new buildings model any aspect of facility operation calculate grids of blast points use just like a library facility

A. Using the VISAC Library Facilities

View library facilities and their pre-calculated grids of blast points use viewers to explore the geometry and logic search grids for specific outcomes

Library Mode

3


Demo of Library Mode

4


Components of Facilities Geometry Model

Buildings, components Overpressure fragility data Link to logic model

Logic Model Event trees, fault trees, consequences Aspects – groups of event tree consequences Calculation parameters Accident definitions

5


Library Facilities Uneditable Basic or Detailed Four pre-calculated grids of blast points

Viewers/Editors of Models Geometry – Edificio, 2D, 3D Ray Trace, QuickView Logic – EFTed Separate grid viewer Extra animations, fully textured still shots

6


B. Running VISAC Projects

Run “What-If?” scenarios using different attacks on the library facilities accidents, component damage, bomb blasts find release probabilities, facility kill & downtime

“What-If?”

Creating VISAC Projects Project – a facility and a set of incidents Incident – accident, region damage, Quick Blast,

component damage, or Quick Blast from grid

Viewers can be used to create some incidents Viewers can display blast damage Variety of reports available for each incident

Timelines available for multiple-incident projects

VISAC Blast Propagation

Uniform ray tracing

Air region method

Directed ray tracing

C. Creating New Facilities

Create a new facility based on the library facilities and create new buildings model any aspect of facility operation calculate grids of blast points use just like a library facility

New Facility

11


Creating New Facility Base new facility on GenPWR Add new diesel generator building

Edit geometry within Edificio New building New critical components

Edit logic model within EFTed Include new backup diesel to train a and b

12


Attack Scenario Incident 1, take out power lines, via sabotage Incident 2, remove diesel generators a and b, via

region damage Incident 3, damage new diesel generator building,

via truck bomb

Creating New User Facilities “Facility Save As…” does NOT copy the pre-

calculated grids, since it assumes user will change geometry and logic models

User facilities are stored in “…\UserFac\..” User facilities are editable, until they are used in a

project VISAC can automatically set up grids, user can

modify the grid parameters before calculation User can edit all parts of the models

15


Editing Geometry with Edificio Buildings from different Library facilities can be

added to the new user facility Buildings can be created, moved, flipped, rotated,

copied, and deleted Components can be created, moved, flipped,

rotated, copied, and deleted

Logic is NOT automatically updated

16


Event/Fault Tree Editor Event trees can be added, deleted, modified Fault trees can be added, deleted, modified Gate Logic: and, or, not, nand, nor, xor
