“…In this context, 0% represents no consensus at all and 100% represents total agreement. This metric is based on Shannon entropy [ 105 ], specifically the alpha and beta entropies, which are used to describe diversity [ 106 ]. It is a way to assess how much participants in a group share similar priorities, or how much their priorities overlap with one another.…”

Since light fidelity (LiFi) and wireless fidelity (WiFi) do not interfere with one another, a LiFi/WiFi hybrid network may provide superior performance to existing wireless options. With many users and constant changes, a network can easily become overloaded, leading to slowdowns and fluctuations in data transfer speeds. Access point assignment (APA) is required with the increase of users, which can negatively impact the system performance and quality-of-service (QoS) due to mobility and line-of-sight (LOS) blockage. Many variables could influence the APA process; these variables are considered as criteria, such as the network capacity, the degree of blockage, the speed of the connected user, etc. Unlike conditional APA methods, recent studies have considered treating these variables as “evaluation criteria”. Considering these criteria can offer better and more accurate results, eventually enhancing the APA process and QoS. However, the variety of these criteria, the conflict amongst them, their weights (importance), and priority have not been addressed so far. Moreover, treating the criteria equally might result in inaccurate outcomes. Therefore, to solve this issue, it is essential to investigate the impact of each criterion on the APA process. In this work, a multicriteria decision-making (MCDM) problem is formulated to determine a network-level selection for each user over a period of time The decision problem is modeled as a hierarchy that fragments a problem into a hierarchy of simple and small subproblems, and the selection of the AP network among various alternatives is a considered as an MCDM problem. Based on the previous works, we are not aware of any previous research attempts using MCDM methods in the LiFi research area for network selection. Therefore, this work proposes an access point assignment framework using an MCDM approach for users in a hybrid LiFi/WiFi network. The experiment was conducted based on four phases: (i) Five criteria were identified and evaluated with eleven APs (alternatives). The outcome of this phase was used to build the decision matrix and an MCDM was developed and built based on user mobility and blockages with various scenarios using all the criteria; (ii) The analytic hierarchy process (AHP) was employed to identify the criterion of the subjective weights of each criterion and to determine the degree of importance supported by experts’ judgement. Determining the weights in the AHP process considered various investigations, including the consistency ratio (CR) and the AHP consensus indicator, which is calculated using the rank-based maximum likelihood method (RGMM) and Shannon entropy techniques. The VIekriteri-Jumsko KOmpromisno Rangiranje (VIKOR) method is adopted in the selection of the optimal AP for the proper selection of whether a LiFi or WiFi AP must serve the users. The integrated AHP–VIKOR was effective for solving the APA and was the best solution based on using weighted criteria simultaneously. Moreover, the ranking outcomes of the developed integrated AHP–VIKOR approach were evaluated using sensitivity analysis. The result of this work takes the APA for hybrid LiFi networks to a new perspective.

“…It can effectively solve complex problems without the need for precise numerical results. It has been widely used in landscape quality evaluation in studies focusing on urban agricultural landscapes [39], public space landscapes [40], urban parks [41], and forest parks [42]. In this study, we used AHP as the method to evaluate residents' perception of the landscape quality of residential communities.…”

Due to continuous urbanization and an increasing need to improve living quality, citizens’ pursuit of landscape quality in residential communities is constantly improving in developing countries, e.g., China. This is especially true in the period when citizens were locked down in their home cities or communities in the context of the COVID-19 pandemic. Studying whether the current landscape in residential communities still meets citizens’ needs is of significance as it is crucial for city planners, landscape architects, and city managers. In this study, we used the analytic hierarchy process method to evaluate the landscape quality of five residential communities, using the case city of Yangling, China. In total, 516 valid questionnaires were collected in May 2022. The results showed that good organization of residential roads and pedestrian systems, the rationality of rest facilities, and the hierarchical richness of plants were the most important aspects for residents. Based on these, optimization design strategies were summarized. We hope to provide a reference for future landscape optimization of existing residential communities, especially in developing countries.

“…It involves landscape planning, landscape design, landscape management [63,64], landscape planting [65], and human welfare [66], which combines the definitions, studies, and projects of LAD in the world. Hence, this study identifies six dimensions that are capable of representing park quality, according to the nature of LAD, based on prior studies, including: (1) landscape planning and design [39,48,64,66,68,69], (2) cultural services [44,70,71], (3) complete and various facilities [43,44,70,71], (4) landscape planting [45][46][47]72], (5) landscape management [9,43,71], and (6) landscape ecology [48,73] (see Table 1). Second, some criteria that are directly related to the six dimensions are also taken from the <Urban Park Grade Rating Standard in Chengdu (DB 5101/T 135-2021)> (UPGRSC), such as artistic, historic, cultural, and scientific values.…”

High-quality urban parks are considered an integral part of health resources as they can deliver diverse ecosystem services. However, the quality of parks is not always similar, resulting in different levels and values of the services provided. A systematic and complete assessment frame of urban park quality is limited. From the perspective of landscape architecture and design, this study aims to propose a comprehensive assessment framework of urban park quality based on six dimensions (planning and design, cultural services, complete and various facilities, landscape planting, landscape management, and landscape ecology), consisting of 27 indicators with different weights by using the objective and subjective weighting method. Taking the city of Chengdu, China as a case study, 100 urban parks are studied via field investigation and scored using methods that consist of a category count, existence score, field measurement, experts score, and photo review and recheck (13,589 images). The results reveal the spatial distribution and differences in park quality, including six quality dimensions and five districts, and the proportion of the existing quality elements in 100 parks. Based on the results, the spatial areas (Barren area, Low-quality area, Medium-quality area, and High-quality area) are identified, which leads to the establishment of the improvement strategies of spatial equity regarding multi-quality parks. The results can help improve the assessment index system of urban parks, guide the landscape planning and design of urban parks for sustainability, as well as provide a reference for future environmental and social equity development, so as to provide insight and reference for decision-makers and designers considering the landscape planning and design of parks.
