# Research on the Evacuation Characteristics of Cruise Ship Passengers in Multi-Scenarios
## 4 Discussion of Simulation Results
### The Analysis of the First 10% and Last 10% of Arriving Passengers  
By analyzing the arrival time distribution of passengers, the general arrival characteristics of the passenger evacuation can be obtained. Combining the characteristics of the first 10% and last 10% of arriving passengers in the simulation result, a comprehensive understanding of the entire evacuation process could be gained. Table 4 shows the proportions of passengers whose initial locations are on different decks. For the first 10% of arriving passengers, it seems that the initial positions of passengers have a significant impact on the arrival. In the day scenarios, passengers on Deck 2 can be evacuated quickly due to the embarkation stations being on Deck 2, and so the proportion of these passengers is largest. In the night scenarios, passengers on Deck 3 and 4 could arrive at the destinations quickly, as these two decks are closer to Deck 2. Consequently, passengers on this deck occupy the largest proportion. For the last 10% of arriving passengers, the higher the deck that passengers are on, the greater the proportion  
of the last 10% they occupy. This means that passengers need more time to arrive at the evacuation destination on Deck 2 if their initial positions are on the higher decks. However, the passenger proportions for Deck 10 in the day scenarios are smaller than the lower decks, and the same situation also appears for Deck 7 under the night scenarios. It can be seen from Table 1 that the initial number of passengers on these two decks is relatively small, so the proportion of passengers is also low. Table 5 shows the proportions of passengers whose initial locations are in different MVZs. In the first 10% of arriving passengers, the proportions of passengers in MVZ 2, 3, and 4 are significantly larger than the other two MVZs. As can be seen from Figure 1, staircases are set on both sides of MVZ 2, 3 and 4, and passengers in these MVZs can evacuate from two directions. Meanwhile, staircases are only arranged on one side of MVZ 1 and 5, and passengers can only move in one direction in the process of evacuation. Therefore, the evacuation efficiency of MVZ 1 and 5 is lower than that of the other three MVZs. For the last 10% of arriving passengers, the proportions of passengers in MVZ 3 and 5 are larger than other MVZs in the day scenario. As can be seen from Table 1, the number of passengers in MVZ 3 is the largest in the day scenario, which may lead to the higher value of the proportion of passengers in MVZ 3. Meanwhile, the reason for the high proportion value of passengers in MVZ 5 is also the layout of the staircases. For the same reason, the evacuation efficiencies of passengers in MVZ 1 and 5 are low under the night scenario, resulting in the proportions of passengers in these two MVZs being significantly higher than other MVZs. Since the initial number of passengers in MVZ 5 is larger than that in MVZ 1, the value proportion of MVZ 5 is higher than that of MVZ 1. Table 6 shows the proportions of different types of passengers. For the first 10% of arriving passengers, their walking speed has a significant impact on evacuation, and the faster the walking speed is, the higher the proportion value of the passengers is. In four scenarios, the proportions of type 3 and 8 passengers are the largest in female and male passengers, respectively. It can be seen from Table 2 that, although the walking speeds of
