چکیده

The main goal of the present study is to generate GIS-based landslide susceptibility map (LSM) Meghalaya, India. For this purpose, two bivariate statistical (FR and SE) multi-criteria decision analysis (AHP Fuzzy-AHP) methods are utilised. area situated over Shillong Plateau in North Eastern Region India subjected numerous landslides due heavy rainfall seismic activities. To obtain LSMs, a inventory 1330 events 15 conditioning factors prepared. dataset randomly split into 70/30 ratio make training testing datasets for study. results show that southern escarpment, southeast region hillslopes along roadsides highly susceptible landslide. LSMs validated using under curve (AUC) values F1-scores, which AHP (AUCAHP = 0.913; F1-score 0.884) shows highest prediction accuracy Meghalaya. generated can help risk mitigation strategies sustainable infrastructure development.

A Fuzzy Comprehensive Evaluation Method Based on AHP and Entropy for a Landslide Susceptibility Map

Landslides are a common type of natural disaster in mountainous areas. As a result of the comprehensive influences of geology, geomorphology and climatic conditions, the susceptibility to landslide hazards in mountainous areas shows obvious regionalism. The evaluation of regional landslide susceptibility can help reduce the risk to the lives of mountain residents. In this paper, the Shannon ent...

Using DEA and AHP for Ratio Analysis

This research proposes an integrated approach to the Data Envelopment Analysis (DEA) and Analytic Hierarchy Process (AHP) methodologies for ratio analysis. According to this, we compute two sets of weights of ratios in the DEA framework. All ratios are treated as outputs without explicit inputs. The first set of weights represents the most attainable efficiency level for each Decision Making Un...
