Progress in the development of a computerized aircraft cabin evacuation model is described. The model has a two-fold purpose i to supplement current certification tests that use human subjects, and ii to serve in the investigation of aircraft accidents as a reconstruction tool and identify factors influencing survival of passengers. For the model to be a valid predictive tool when simulating aircraft accidents, the toxic and debilitating effects on passenger behavior of fire and smoke must be modeled. Other aircraft cabin evacuation models use an expert systemrule-based approach to simulate these effects. The work described here presents an object-oriented approach to modeling human behavior in aircraft cabin evacuations. Object-oriented programming OOP lends itself to the modeling of complex systems. OOPs foundation is modularity. OOP allows a one-to-one correspondence with the physical world, and thus, eases the burden of model validation. Validation is critical to the successful use of a model as a predictive tool and involves testing to ensure that the model accurately reflects the behavior of a real system. Easing model validation is of particular importance since the real systems environment is hazardous, and performing any tests on the real system is either impossible or not repeatable. The result of this work will help to expand the simulations capabilities in improved passenger queuing analysis by allowing the incorporation of human behavior into class objects.
