Toyon’s Homeland Security Systems Engineering Team provides a spectrum of services related to evaluating methods for protecting facilities from chemical, biological, and radiological (CBR) threats. The HS systems engineering team’s capabilities include:

Application of systems engineering techniques and methodologies to a range of issues associated with protection of facilities from CBR attack.

  • Technology assessments
  • Effectiveness evaluations
  • Cost/benefit analyses
  • Concepts of operations/response procedures

Modeling and simulation

  • Developing mathematical models for transport of CBR agents inside facilities
  • CONTAM multi-zone airflow model
  • Modeling CBR threats for evaluating new and available technologies

Test planning and execution for characterizing facilities

  • Airflow properties
  • Population characteristics
  • Contaminant transport measurement using tracer gas (e.g. SF6) releases
  • Flow, pressure, and building leakage measurements

The majority of Toyon’s Homeland Security Engineering Team works on confidential classified projects. Recent unclassified projects include:

  • Building Protection Toolkit – Sponsor: DARPA. Project: support the creation of the Building Protection Toolkit (formerly Immune Building Toolkit)
  • Counter Underground Facilities – Sponsor: DARPA. Project: characterize underground connectivity between above-ground buildings
  • Mail Facility – Sponsor: US Postal Service/Northrop Grumman. Project: assess placement of biological detection systems at Curseen-Morris (formerly Brentwood) postal facility
