FUNDAMENTAL STUDY ON ASSESSMENT OF ACCURACY IN SIMULATION OF EARTHQUAKE INDUCED URBUN SPREADING FIRE BY PETRI-NET

Abstract

 The formulas of spreading velocity of fire are generally used in the simulation of the earthquake induced urban spreading fire. The formulas are constructed based on the physical base and the field investigate in the past urban fires. Therefore, the uncertainty of the formulas is inevitable. In this study, an effective method is presented to evaluate the reliability of estimated arrival time of fire which is calculated by Petri-net using such the formulas of spreading fire with uncertainty.
