“…Some functional operations are implemented in the GIS-MCDM approach, such as Analytical Hierarchy Process (AHP) and weighting. AHP method is a flexible and simple Multi-criteria Analysis (MCA) and it has been largely explored in the literature related to location identification as conducted in several studies in Malaysia (Saad et al, 2021;Mohd Zaini., 2021;Rasam et al, 2017;Abdul Rasam et al, 2016;Mamat et al, 2014;Othman et al, 2021). AHP is recognized for its ability to consider tangible and intangible criteria in giving solutions to a multi-criteria problem.…”

Electrical energy is indispensable for the economic growth and well-being of humanity. However, there is a growing concern with the conventional method of generating electricity which is by burning coal and other fossil fuels. In the coming decades, the world will experience a transition to cleaner energy, away from the use of fossil fuels. One of the clean and renewable energies that is getting more popular and advancing in technology is wind energy. Wind energy requires a proper location to operate in order to be profitable and have the desired impact on society. In search of a suitable location for wind energy, a Geographical Information System based Multi-Criteria Decision Making (GIS-MCDM) approach was utilized in this paper to explore the suitable areas for wind energy development in Selangor. Eight parameters were chosen to address this concern, including terrain elevation, terrain slope, road network, airport locations, forests, settlements, water bodies and average wind speed. All of these criteria were weighted using the pairwise comparison approach in MCDM, and the decisionmaking process was facilitated by the criteria utilizing the ArcGIS-weighted overlay tool. The study has identified seven potential sites, but only four sites that are practically located the wind energy site, which are Banting, Jeram, Ijok and Kerling. GIS-MCDM can assist the decision-maker in designing the optimal placement of wind farms in real scenarios.

Millions of people were harmed by landslides, and many have lost their lives. Instead of widening the access road during a landslide, an alternative or new road should be introduced accurately. This study was conducted to determine an appropriate GIS-based alternative planning route during landslides in Ranau, Sabah, Malaysia. For determining the criteria weights of the landslide, a GIS-based Multi-Criteria Decision Making (GIS-MCDM) technique was utilised with the extension of the Analytical Hierarchy Process (AHP). The Landslide Susceptibility Index (LSI) map was created using lithology, slope, aspect, rainfall, land use or land cover (LULC), and proximity to a stream. The map was compared with the NASA-landslide historical data for the verification. The study found that lithology, slope, and aspect were the most contributing factors to the local landslide occurrences. The route from Pinausuk to the destination position of Kundasang is the most appropriate choice. An alternative planning route map is a helpful tool for the authorities and it might be also made available to the public, so they will know which path can be taken for more secure alternative access during landslides.

“…Additional information, such as location, voltage, and information on electrical distribution, can be provided using GIS. The possibilities of GIS for managing electricity in a building have been practically proved in earlier studies (Saad N, 2021;Pullinger & Johnson 2010). This spatial technique has also been combined with MCDM/MCE to determine whether a certain application is appropriate (Ahmadi, S. et al, 2008;Mohd Zaini J C et al,2021).…”

This study uses a Least Cost Path Analysis (LCPA) to create a transmission suitability route map. Environmental issues including electromagnetic pollution, habitat fragmentation, forest clearing, and the sight of pylons and power lines, and electromagnetic pollution are just a few that may come up during the planning and construction phases. The study's objectives are to define the criteria for a suitable transmission route, map the current transmission from Kidurong to Kemena in Bintulu, Sarawak, and suggest a new, LCPA-based transmission route that meets these criteria. It is necessary to determine the criteria that influence the construction of the route. There are three main categories for the proposed routes. There are technical, human health, and natural environments. The road layer and slope layer are combined for the technical group. The residential layer is part of the human health group, and land use is associated with the natural environment. During the planning of a potential power line route, weight was assigned to the criterion maps. The outcome demonstrates that the suggested route was built based on most flat sections, with only a little portion passing through the sharpest sector because there is no other way to depart from the path to avoid it. The output route is nearly straight from the source location to the destination point. The route also curves in a couple of places to go around the step area. The proposed transmission line is inside the buffer zone, and there are no other routes in the area that are more than 1 km from the road. Class 1 has a low dwelling density; therefore, the route passes through it for the residential evaluation. Additionally, there are a few places where the route passes through class 2 because only class 2 has a lower housing density.
