SCHEMA-SI: A Hybrid fire safety engineering tool-Part I: Tool theoretical basis

SCHEMA-SI is an engineering tool able to evaluate the performance of building fire safety system. It uses a dynamic hybrid model, which means that discrete events and continuous phenomenon are interconnected at each instant. The model has been developed as a tool to assist fire protection engineers in performing fire safety engineering calculations. This tool may be also used to conduct risk assessments and to evaluate whether selected design strategies are sufficiently safe in case of fire in a specific building. Part I of this paper describes the basis of the SCHEMA-SI tool. Sub-models used to perform calculations are discussed. Part II of this paper focuses on a real case study.

► An engineering tool able to assess fire risk was built. ► This tool uses Monte Carlo method in order to compute thousands of fire scenarios. ► The tool is based on the hybridisation of a two-zone model and Petri nets. ► This part of the paper focuses on the tool theoretical basis. ► Next part will focus on a case study on a French Hostel.
