An Evacuation Algorithm for Digital Twin Building Fire System

Abstract

When a fire breaks out people need to make decisions immediately to determine how to escape because the opportunity to escape is usually only in the early stages of the fire Taiwan's fire death peaks are between 20 and 60 years old These people are killed in the fire not because of their mobility This shows that people do not know how to respond correctly when facing the fire which is one of the main reasons for the death of the fire In this paper to decrease the danger of people during the evacuation in the indoor fire the research on building fire system will include two parts (1) Establish a system architecture based on the concept of the digital twin Under this framework when a fire occurs in the real world the application of the system can give people the escape proposal and plan according to the data and algorithms in the digital twin (2) Propose a heuristic algorithm based on the concept of force for indoor path planning In the fire the algorithm chooses a safer exit according to the location of personnel and fire and establish a route to help people avoid the danger of close to the burning area when they escape to the exit In the experimental part the escape survival rate is compared with other methods to show that our method can improve the survival rate of people in the event of a fire escape
