The selection of a desirable site for constructing a pumped hydro energy storage plant (PHESP) plays a vital important role in the whole life cycle. However, little research has been done on the site selection of PHESP, which affects the rapid development of PHESP. Therefore, this paper aims to select the most ideal PHESP site from numerous candidate alternatives using the multi-criteria decisi...

Iran is one of the flood-prone areas in world with inappropriate climatic patterns. In this study, flood risk maps three scenarios by combining Analytic Hierarchy Process (AHP), Analytical Network (ANP) and Fuzzy (FAHP) models Ordered Weighted Average (OWA), Linear Combination (WLC) models., Local (LWLC) two new models, Multi-Criteria Analysis (WMCA) Geo Technique for Order Preference Similarit...

Surface mining projects are vulnerable to natural hazards (earthquakes, floods, soil instabilities, and epidemic crises) which constitute the primary source of risks affect operations. In framework sustainable planning development such projects, investigation risk impacts is essential for taking appropriate preventive measures before disastrous events appear in a mine. This paper proposes metho...

Deep excavation construction safety has become a challenging and crucial aspect of modern infrastructure engineering, its risk assessment is frequently carried out using the Fuzzy Analytic Hierarchy Process (FAHP). However, when FAHP to evaluate risks deep construction, results weightings obtained through subjective weighting are heavily influenced by factors evaluators. In addition, linear ope...
