Linear programming theory in evacuation research

To calculate the request safety evacuation time(RSET), it is necessary to get the evacuation start time and crowd density.Through measuring the number of persons in one library and inspecting the construction plans,the range of those parameters can be determined.Build the linear programming model which is based on population dynamics,and use the Matlab to calculate the minimum RSET,then the best value of the evacuation start time and crowd density can be determined.Those values are helpful for development of evacuation plans and the management of fire safety.
