Towards a spatio‐temporal multicriteria evaluation method: A suitability analysis of residential units in a 3D urban environment

Abstract

Spatial multi‐criteria evaluation (MCE) techniques aid urban planning management by analyzing decision problem alternatives for solutions to help inform decision‐making. However, there is a lack of such methods that incorporate the temporal dimension, an important factor when analyzing the dynamic urban landscape and decisions surrounding its changes. A novel spatio‐temporal MCE approach is proposed that operates in three‐dimensional (3D) space and time to identify changing suitability values of decision alternatives. This space–time method is implemented to evaluate the suitability of residential units over a 15‐year period in part of downtown City of Vancouver, Canada. The results indicate that the majority of units exhibit a decrease in suitability with time due to depreciation and reduction of assets like view and privacy from the construction of new buildings. The proposed method can be used by urban planners and developers to assist in long‐term assessments of proposed development scenarios and their impact on existing urban infrastructure.

Improving Hierarchical Ecosystem Structures and Multicriteria Evaluation for Current Land Ecosystem Classification

“…Therefore, it is necessary to compare the ecosystem components crossing comparable structure levels quantitatively (Fábregas-Tejeda and Vergara-Silva 2018; Jafary et al 2018). Using multicriteria evaluation, Gunaydin et al (2022) and Munn and Dragićević (2023) demonstrated the quality of the analysis when they compared different environmental systems at various scales.…”

“…Consistently, we aimed to identify multiple components of abiotic and biotic factors at various levels and to create the top, focal, and lower-level ecosystem classifications for a territory ecoregion. Furthermore, we evaluated some hierarchical ecosystem theories (Kolasa and Pickett 1989;Wu and David 2002;Wu 2013;Valérie 2017) and accessed the LECs using classic ecosystem components and multicriteria evaluation (Anderson and Dragićević 2020;Yuan et al 2022;Munn and Dragićević 2023) at the global continental scale.…”
