Delineating Zones of Groundwater Recharging Potential using Geospatial Techniques Integrated with GRA-TOPSIS - A Case Study of Wassa West District of the Republic of Ghana
Abstract: Identifying and analyzing environmental parameters for assessing groundwater existence and recharge potential using geospatial techniques is crucial and cost effective, particularly for areas where surface water is contamination due to illegal mining activities. In this study, GIS and Multi-criteria decision analysis tool, GRA-TOPSIS, were used to identify groundwater recharge zones in the Wassa West District of Ghana. The study considered geo-environmental factors such as slope, soil types and lithology, land …

Optimal Selection of Control Factors in Abrasive Water Jet Cutting of Titanium Grade 5
Abstract: The Technique for Order Preference by Similarity Ideal Solution (TOPSIS) approach was used to carry out optimization studies on an abrasive water jet (AWJ) cutting process with multiweapon characteristics based on Multi Criteria Decision Making Methodology (MCDM). The process parameters water jet pressure, traverse rate and standoff distance are optimized with multiresponse characteristics, including the depth of penetration (DOP) smooth zone (SR) . The optimized results obtained from this approach …

Application of TOPSIS Method for Selection of Best Natural Fiber for Retrofitting of Structure
Abstract: Selection of best natural fiber is multi-criteria decision problem including both quantitative and qualitative criteria. Decision-making problem is the process of finding the best option from all of the feasible alternatives. In this paper, from among multi-criteria models in making complex decision and multiple attribute models for the most preferable choice, technique for order preferences by similarity to ideal solution (TOPSIS) approach has been dealt with. Technique for TOPSIS is …

Concrete Oil and Gas Platforms in Offshore Marine Environment: A Review
Abstract: Abstract Offshore concrete structures have been successfully in use since 1973. Since then, 47 major concrete offshore structures were built worldwide. They were mostly used in the petroleum industry as drilling, extraction or storage units for crude oil or natural gas. Generally, offshore concrete structures are classified into fixed and floating structures. Fixed structures are mostly built as concrete gravity based structures where the loads are directly transferred through concrete …

Structural Design of Offshore Structures: A Review of Indian and International Standards
Abstract: Offshore structures—including fixed steel jackets, topside modules, offshore wind turbine support structures, and floating systems—are designed to withstand combined gravity, environmental, seismic, and operational loads under substantial uncertainty and limited access for inspection and repair. Structural design practice has historically relied on internationally recognized standards, particularly the American Petroleum Institute’s API RP 2A, the International Organization for Standardization’s ISO 19900 series, including ISO 19902 for fixed steel structures, and Det …

An Experimental Study on Multi-Criteria Parameters Optimization of Process for Al6351/SiC/Gr Metal Matrix Composites Using AHP-TOPSIS Approach
Abstract: This research focuses on optimizing the process parameters of Wire Electrical Discharge Machining (WEDM) for a hybrid Metal Matrix Composite (MMC) comprising Al6351 aluminum alloy reinforced with 4% SiC and 6% graphite (Gr), fabricated via squeeze casting. This technique enables the formation of dense, defect-free composites with uniform reinforcement distribution, enhancing both mechanical properties and structural integrity. Microstructural characterization using Scanning Electron Microscopy (SEM) confirmed the even dispersion and bonding …

Evaluating the Best Belt Conveyor Assembly Using TOPSIS Approach
Abstract: This article presents a new approach for the selection of Belt Conveyor of screening creaser on the basis of their performance. This article includes the effective factors like angle of response, load capacity of motor, raw material load capacity, raw material dimension. These all important factors affect the performance of Belt Conveyor Assembly. Therefore, determination of the best Belt Conveyor is basically a Multi-Attribute Decision Making (MADM) problem. Our aim …
