Evacuation behaviors are series of actions such as recognition of disaster, initial response, judgment of situation, starting of evacuation and evacuation action. Success of evacuation seems to greatly depend on starting time of the evacuation and selection of escape route among various evacuation behaviors. In case of fire, failure of evacuation often caused by "delay of starting of escape" and "improper selection of escape route". Therefore, it is extremely important for success of the evacuation that the order for starting evacuation at the early stage of the disaster and the guidance for the appropriate escape route. In other words, guidance of the evacuation by crew is significant for the success of the evacuation. In the previous paper, we presented the layered ship's space model constructed with primary elements by spaces and nodes, the evacuee's model which manages behavior of each evacuee, and introduced the fire scenarios. In this paper, new model for starting time of the evacuation is introduced to simulate the situation of the evacuation based on the guidance by crew. Using these models, several evacuation simulations were carried out and evacuation situation of evacuees were estimated. The results of the simulation shows that the starting time of the evacuation, the initial location of evacuees, the smoke movement and the selection of the escape route significantly affect the situation of evacuation. Especially, it was understood that the starting time of evacuation has great influence on success of the evacuation.
