“…there are evacuation models that treat people not as ball bearings but as clairvoyant geniuses. [9] Occupants are provided with complete and accurate information on building layout and location and implications of fire conditions, instantaneously, not only in their immediate vicinity but in remote locations where they could have no realistic access to information. These models can incorporate differences in people's abilities, at least their physical abilities, but in terms of decision-making, every occupant is treated as an omniscient.…”

Science requires falsifiable propositions, preferably assembled in structures that provide nonobvious predictions across a wide scope. The human behavior and probability branches of fire safety science meet this definition. The topic of fire safety science, as distinct from fire science, demands human behavior and probabilistic modeling. In both human behavior and probabilistic modeling applied to tire safety science, there are multiple schools and approaches, often reflecting disputes over how much it is necessary or possible to imitate the structures and elen~ents of the hard branches of fire safety science. A review of these approaches and the state of the art provides a basis for greater understanding of the nature and importance of the soft branches of fire safety science-and the hard fact that they are worthy of the name "science" and essential to any valid and useful fire safety science structure.

“…Approaches to this problem can be divided into macro and microscopic models [13]. The former approaches are dynamic network flow models mainly used to calculate the optimal evacuation times [14][15][16][17], whereas microscopic approaches concentrate on the simulation of individual behaviors [18][19][20][21][22][23]. Both macro and microscopic approaches can be used for evacuation planning.…”

This paper proposes a new real-time decision method to select optimal evacuation routes. The mathematical formulation, the solution algorithm and the computer model are presented. The optimization algorithm is based on the stochastic evacuation model predictions by considering emergency data such as the location of the hazard. The method was applied to an industrial building. The stochastic evacuation model was compared with the commercial evacuation model STEPS involving 14 potential evacuation routes and the computational model was applied to 10 hypothetical emergency scenarios to demonstrate its validity.

“…Another approach to the problem is the realized (Kostreva, 1991;Getachew, 1992Getachew, , 2000Wiecek, 1992Wiecek, , 1993, who formulate the building evacuation as a multiobjective problem. Continuing this line of research we find Lo and Huang (2000, 2008.…”

Nowadays, there exist different offers to find the solution of the building evacuation problem. As we analyze in the state of the art, this problem can be studied from different perspectives and even as a problem of optimization considering different objectives. We can wonder on which is the most suitable formulation and the response can be as confusing as saying that it depends on our aims. The more important things to study the ideal building evacuation, understood as the distribution of the occupants towards the exits that achieves the minimal evacuation time, are the valid principles for any formulation of the problem. One of them appears in the present work. To expose the principle, we use graphical procedures that are applied to the optimization of the enclosure evacuation. In the exposed procedure, speeds and constant flows of traffic are considered to model the movement of the persons. Ways and possible delays in the beginning of the bulging evacuation are studied.
