Multiobjective Optimization of Evacuation Routes in Stadium Using Superposed Potential Field Network Based ACO

Algorithm 1

Formulation of multi-objective evacuation routes optimization problem.

  Finding the pareto optimal set [21] of evacuation

plans, make

𝑓₁𝑓=min(TET)₂𝑓=min(TERL)₃=min(CCD)

Subject to

𝑁_𝐸𝑖(𝑡)≤𝐶_𝑖,

where, 𝑁_𝐸𝑖(𝑡) is the number of evacuees in subzone 𝑖 at 𝑡th

time step, 𝐶_𝑖 is the capacity of subzone 𝑖.
