Fire risk and loss assessment system

Abstract

This invention provides a fire risk and loss assessment system. The input module extracts multiple fire risk factors from factory data. The calculation module connects to the input module and calculates a basic risk index and interaction parameters based on the fire risk factors to generate a comprehensive risk index. The dynamic coefficient adjustment module connects to the calculation module and includes a coefficient generation model to generate weights for calculating the basic risk index and interaction parameters based on multiple historical factory risk data. The loss conversion module connects to the calculation module and converts the comprehensive risk index into a Maximum Probable Loss (PML) index based on historical factory risk data and corresponding loss results. The output module connects to the calculation module and the loss conversion module and outputs the corresponding fire risk index and PML index based on the comprehensive risk index and PML index.
