Automatic selection of weights for GIS-based multicriteria decision analysis: site selection of transmission towers as a case study

“…However, we found two articles in which the weights are presented and therefore allow a comparison of our results. The first is the paper by Monteiro et al (2005), who used MCDA for TL siting in Spain. In this article the authors suggest that distance to urban areas is one of the crucial geographical features to consider when placing TL, and also that TL are often built along roads to "concentrate the impact of roads and power lines in the same geographical areas" (Monteiro et al, 2005).…”

This article however did not consider the other factors we included in our analysis so these two conclusions are the only ones that we can use for comparison.…”

Hexagon raster‐based method for distribution network planning considering line routes and pole locations

“…The raster method is utilised to divide the terrain into small cells and define the candidate line routes based on the linkages between cells. The idea of rasterisation was first proposed in [25,26], which focused on GIS spatial methodologies for simple point-to-point overhead economic corridor selection for a new power line using an advanced dynamic programming method. The authors of [27,28] further improved the raster method and formulated the line routing problem as a mixed-integer linear programming (MILP) problem, suitable for multi-line routes and generation expansion planning.…”

“…To promote computational efficiency, Shu et al [28] presented a two-step approach wherein the first step searched optimal electric line routes via dynamic programming and the second step solved a simplified MILP problem to obtain overall generation and transmission planning strategies. The raster methods of [25][26][27][28] are all based on square cells, which arise naturally from the pixel format of GIS maps; however, the square cell-based model has some deficiencies. First, the diagonal directions of a square cell are different from the orthogonal directions: one cell and its diagonal neighbour only share a vertex at the vertical angles, while the orthogonal neighbours share a common arm; thus, the corridors for diagonal directions have no width.…”

“…Selection of the power pole locations has been neglected in the previous studies, although this plays a critical role in line routing in complicated environments. The cell-cross models proposed in [25][26][27][28] cannot cross valleys and gullies, where the routes must meander on the ground. However, in practice, lines are placed on poles, making it possible for lines to cross certain simple obstacles.…”
