  -SIFRA stands for **System for Infrastructure Facility Resilience Analysis**.
  +SIRA stands for **System for Infrastructure Facility Resilience Analysis**.
   It represents a methodology and supporting code for systematising vulnerability
   analysis of lifeline infrastructure to natural hazards (i.e. response of
  -infrastructure assets to environmental excitation). SIFRA is open source.

   The impact assessment is based on the fragilities and configuration of
   components that comprise the infrastructure system under study. The analytical

  Following code snippets assume that it is being run from the root directory
  of the SIFRA code, and the model of interest is in the location
  `sira/scenario_dir/ci_model_foo`.
  
  The following code runs the simulation and the post processing simultanrously:
  
negative.code: has been done in the code backend to extend the same methodology to modelling
  network vulnerability as well (e.g. electricity transmission networks).
  
  SIRA models are based on graph theory. All infrastructure systems are
  represented as networks. This allows an user to develop arbitrarily complex
  custom facility models – for a Facility or a network – for impact simulation.
