Appropriate evacuation strategies play an important role in saving lives during tsunamis. Evacuation by vehicle is generally not recommended, as it would induce severe congestion on roads. Nevertheless, it could be helpful for vulnerable people (e.g. the disabled, elderly, or infants) who live in an area which a tsunami would reach immediately after an earthquake, and cannot walk fast. Despite this, to date there are few simulation tools that can accurately reproduce the evacuation behavior of both pedestrians and vehicles as well as the tsunami inundation process. To help disaster risk managers with this problem, the authors newly developed an agent-based tsunami evacuation model that can consider both tsunami wave hydrodynamics and the behavior of both of these types of agents (i.e. vehicles and people) during evacuation.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/ZurujpEE0hY

Merging Behavior

In order to analyze the evacuation capacity of parallel double running stairs, a dozen stairs merging forms are set by investigation and statistics, and the improved agent-based evacuation model that considers the merging behavior is used to simulate the process of merging and evacuation in the stairs. The stairs evacuation capacity is related to the evacuation time and the robustness of stairs, and the evacuation time can be calculated by using the improved agent-based model based on computer simulation. The robustness of each merging form can be obtained according to the fluctuation degree of evacuation time under the different pedestrian flow. The evaluation model of stairs evacuation capacity is established by fusing the evacuation time and the robustness of stairs. Combined with the specific example to calculate the evacuation capacity of each stairs form, it is found that every merging form has different evacuation time and different robustness, and the evacuation time has not positive correlation with the robustness for the same form stairs. Meanwhile, the evacuation capacity of stairs is not related to the number of the floor entrances. Finally, the results show that the evacuation capacity of stairs is optimal when the floor entrances are close to out stairs in parallel double running stairs and suitable to the case where pedestrian flow and the change of pedestrian flow are large.

Economic Well Being

The 1982 Long-Term Care Survey (N = 5,670) was used to gain an understanding of predisposing, need, and enabling variables that influence the economic well-being of disabled elderly. Stepwise regression results suggest that a combination of enabling and predisposing factors best explained differences in economic well-being. Implications of the findings for practitioners are discussed within the context of practice and policy for the disabled elderly.

It is an urgently problem to be solved that how to test a weapon system-of-systems capabilities in a joint operational context. Firstly, based on the capability assessment of weapon system-of-systems, a procedure of weapon system-of-systems capabilities evaluation strategies design space is proposed. Secondly, supported by agent-based simulation tools, an exploratory analysis example is given which uses the fractional factorial design and stepwise regression fit. This paper makes a better try on the measures selected of the system-of-systems capabilities in the early period of weapon equipment acquisition.
