Summary
Climate change necessitates better urban planning for human mobility during disasters. A new hybrid intuitionistic fuzzy method helps determine the best evacuation strategy under uncertainty, recommending preparedness.
Area of Science:
- Environmental Science
- Disaster Management
- Decision Science
Background:
- Global climate crisis drives economic damage and mass migration due to environmental disasters.
- Existing emergency evacuation research inadequately addresses fuzzy and uncertain conditions inherent in disaster modeling.
- Intuitionistic fuzzy logic offers a framework for expert hesitation in evaluating evacuation criteria.
Purpose of the Study:
- To develop a hybrid intuitionistic fuzzy method for optimizing evacuation strategies in uncertain environments.
- To address the need for effective human mobility strategies amid climate-induced disasters.
- To enhance urban sustainability and preparedness for climate-related emergencies.
Main Methods:
- Developed a hybrid intuitionistic fuzzy approach to model evacuation necessity.
- Applied the method to Jiangxi Province, China, during Typhoon Maria.
- Evaluated evacuation necessity based on seven criteria with five response alternatives.
Main Results:
- The proposed method identified 'alertness' (preparedness for evacuation) as the most desirable strategy for Typhoon Maria.
- The hybrid intuitionistic fuzzy method demonstrated superior performance compared to other existing intuitionistic fuzzy approaches.
- Quantified evacuation necessity under uncertain, fuzzy conditions.
Conclusions:
- The hybrid intuitionistic fuzzy method effectively determines optimal evacuation strategies in uncertain environments.
- Preparedness ('alertness') is a critical human mobility strategy for climate-related disasters.
- The approach enhances urban sustainability and decision-making in disaster preparedness.

01:37Reason and Intuition
7.7K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

01:09Decision Making: P-value Method
7.4K
The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can...

01:17Design Example: Analyzing Capacity Contours for Flood Risk Assessment
384
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

715
Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...

Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
