Three Ways To Use VISAC

1
Three Ways To Use VISAC

• View library facilities and their pre-calculated
  grids of blast points
• use viewers to explore geometry and logic
• search grids for specific outcomes
• Run what-if? scenarios using different attacks
  on the library facilities
• accidents, component damage, blasts
• find release probabilities, facility kill
  downtime
• 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
Library Mode

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

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

B. Running VISAC Projects
What-If?

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

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

9
VISAC Blast Propagation

• Uniform ray tracing
• Air region method
• Directed ray tracing

10
C. Creating New Facilities
New Facility

• 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

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

14
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
