“…According to our literature review, the fuzzy AHP (FAHP) method is also used in many studies, but its weakness is that it is affected by stakeholder preferences. In addition, the FAHP is a very complex method that requires more numerical calculations than the AHP (Albraheem & Alabdulkarim, 2021).…”

Spatial modeling of migration and the identification of the effective parameters are imperative for planning and managing demographic, economic, social, and environmental changes on various geographical scales. The recent climate change stressors as well as inequality in terms of education and life quality have triggered internal mass migrations in Iran, causing pressure on housing, the job market, and potential slums around large cities. This study proposes a new approach to modeling migration patterns in Iran based on multi‐criteria decision analysis. For this purpose, a total of 23 individual criteria embedded within four criteria groups (economic, socio‐cultural, welfare, and environmental) affecting national migration were used. The analytic hierarchy process was employed to determine weights for the input factors and the weighted linear combination (WLC) model was used for the integration of criteria, based on which maps of migration potential were produced. The model applied was evaluated based on the correlation coefficient between migration potential values obtained from the WLC model and the actual net migration rate. Among the input individual criteria, unemployment, higher education centers, number of physicians, and dust storms were found to influence national migration. Furthermore, our findings reveal that the potential for migration across Iranian provinces is heterogeneous, with the spatial potential for emigration being the highest and lowest in the border and central provinces, respectively. The correlation coefficient calculated between outputs from the WLC model and the net migration rate from 2011 to 2016, was .81, indicating the relatively high performance of the proposed model in producing a migration spatial potential map. Our proposed approach, along with the results achieved, can be useful to decision‐makers and planners in designing data‐driven policies against inequality‐ and climate‐induced stressors.

“…Among them, the analytic hierarchy process is widely used in various fields due to its simple operation and concise system. For example, it is used for collaborative evaluation in the company's operation management [26]; in software-defined networks, it is used for controller selection [27]; in the design of urban tourism routes, it is used to evaluate tourism resources [28]; it is used to evaluate the importance of active power in research [29]; it is also employed to select the most suitable city when solving spatial problems [30], etc. However, the analytic hierarchy process also has its shortcomings that it cannot solve the comprehensive evaluation problem of multi-person decision-making conflicts.…”

“…When calculating the degree of relevance, the existence of normal random numbers would also make the result of the calculation not unique, so it was necessary to calculate the expected value E rx and entropy E rn of the comprehensive evaluation score after multiple operations [30]. The calculation formula is as shown in Equations ( 17) and ( 18):…”

In the process of economic development, the exploitation and utilization of resources has played an important role, but the subsequent post-mining collapse and the shortage of land resources have affected future reconstruction to a certain extent. Currently, there is a firm belief in sustainable development and its goals to be achieved in the future. Based on the concept of sustainable development, this paper examines the feasibility of rebuilding channels under adverse geological conditions, and studies whether there are risks and the degree of risk. According to the characteristics of the experts’ judgment language and the ambiguity and randomness between various factors, it is proposed that a cloud model is used to improve the AHP (Analytic Hierarchy Process) risk assessment method. At the same time, the traditional matter–element theory is improved through the cloud model, so that the impact of uncertainty and randomness can be comprehensively considered in the evaluation; finally, forming the risk assessment system of the cloud-based AHP and cloud-based matter–elements. The application of examples shows that, compared with the methods in the relevant literature, the evaluation results of this article are more objective, more accurate, have better applicability, and play an important guiding role in channel construction under adverse geological conditions.

“…To reasonably plan and use the MCDA, the various criteria contributing to the decision-making process have to be ranked and weighted, as per their relevance and importance [20]. Analytic Hierarchy Process (AHP) [24], [25] has recently become attractive as a sufficient MCDA tool with potential for various uses [15], [26]- [35]. Interestingly, combining the AHP with a GIS platform leads to optimizing a site-specific seismic design and planning [36], [37], as well as enhancing the scope of conventional hazard assessment maps [8].…”

Seismic Hazard and Site Suitability Evaluation Based on Multicriteria Decision Analysis

Effective management and planning for sustainable urban regions' development require up-todate information. Natural hazard maps (NHMs) creation is critical for urban development. Urban areas along the western coast of Saudi Arabia are susceptible to natural disasters due to their hazard sources' proximity, especially, with the lack of preparation. Yanbu' Al-Bahr, a major Red Sea port, provides an excellent example. This research aims to combine NHMs into a single multi-hazard map, allowing acceptable site identification for urban development. To create a seismic hazard model of the rapidly growing Yanbu' Al-Bahr region, spatial distributions of different hazard entities were assessed using the analytical hierarchy process (AHP). To create a multi-hazard map, six seismic hazard assessment maps were independently developed. Hazard attributes were assimilated into a geographic information system (GIS) platform to delineate seismic hazard zones and build a suitability map for urban development. Weight and rank values were determined during AHP and assigned to each layer and its corresponding classes. By overlaying all the weighted maps, a suitability map was created. This map depicts the research area's prospective appropriateness for urban growth. Accordingly, the study area was classified into five hazard categories, namely, very-low (VL), low (L), moderate (M), high (H), and very high (VH). Therefore, the limited regions, most appropriate locations, and least suitable areas were identified. Accordingly, stakeholders can use the produced seismic hazard map as a platform for future land-use planning and environmental hazard management. Furthermore, the AHP-GIS model would deliver more precise findings in urban development site selection studies.
