A model approach for post evaluation of adaptive reuse of architectural heritage: a case study of Beijing central axis historical buildings

The adaptive reuse of architectural heritage is the basis of embodying its core value, bringing new life to heritage architecture, and is an important way to integrate it into contemporary development. In many current studies, the adaptive reuse of architectural heritage focuses on the research framework of adaptive reuse and the most effective method for adaptive reuse of a certain building. In the whole process, the post evaluation strategy of adaptive reuse based on specific cultural background is ignored, and the adaptive reuse of heritage buildings is a dynamic process. Therefore, this study takes 9 heritage sites along the central axis of Beijing (including three types of single buildings, architectural complexes, and historical and cultural district) as examples. The 25 factors affecting the adaptive reuse of architectural heritage are extracted by the literature retrieval method, and are divided into three categories according to the content: existing fabric, spatial character and policy and value. Then the analytic hierarchy process and fuzzy comprehensive evaluation are used to calculate the factors of 9 heritage sites in matrix, and finally obtain the reuse score of each heritage site. The results show that Meridian Gate has the highest comprehensive score for reuse in single buildings, the Forbidden City has the highest score for reuse in building complex, and Qianmen Street has the highest score in historical and cultural district. This study provides post-evaluation methods and strategies for the adaptive reuse of architectural heritage. Finally, a post-evaluation framework for the adaptive reuse of architectural heritage is formed. Finally, a post-evaluation framework for the reuse of architectural heritage against a specific cultural background has been formed. In the future, the status of the reuse of architectural heritage can be evaluated to maintain its proper authenticity, integrity and sustainability at any time. It can also guide the relevant decision-making before the adaptive reuse of architectural heritage and the optimization process after the adaptive reuse of architectural heritage.

The rationality and validity of the proposed evaluation system is verified in accordance with field projects and case studies.FindingsTaking into account traditional and cultural factors, the evaluation model established has an acceptable accuracy. Evaluation based on subjective-objective combination can provide a scientific basis for the management and optimization of night lighting.Originality/valueThe proposed evaluation system can serve as a guiding reference for other areas of cultural identity and esthetic perspective.

Risk assessment of oil and gas pipelines hot work based on AHP-FCE

A new quantitative risk assessment method for hot work is proposed based on the Analytic Hierarchy Process (AHP) and Fuzzy Comprehensive Evaluation (FCE). It can help pipeline companies realize the risk management of hot work and further ensure the safe operation of oil and gas pipelines. Taking one natural gas pipeline in China as an example, this paper evaluates the risk of a single hot work in the spring of one natural gas pipeline in a high consequence region. First of all, the risk factors are determined with reference to the job safety analysis (JSA), and then experts were invited to fill out a questionnaire to collect their opinions. According to the results of the questionnaire, AHP is used to calculate the weight coefficients of the evaluation indicators, and FCE is used to evaluate the risk level of hot work. After calculation, the comprehensive risk score of hot work is 40.888. It belongs to a "General risk". This method can not only quantitatively evaluate the risk levels of hot work, but also reasonably sort the importance of various risk factors. It is helpful for the effective management of hot work and provides suggestions for implementing control measures.

Society 5.0 promotes the use of artificial intelligence in human life and the return of humanity to the center of the world. Society 5.0 seeks to achieve economic growth while overcoming social and environmental challenges, contributing to the welfare of the global community. The purpose of this study is to explore how digital transformations introduced by Society 5.0 can contribute to the realization of sustainable development? To answer this question, the study primarily used the systematic literature review method to identify the dimensions and indicators that would quantify the role of Society 5.0 in achieving sustainable development. Then, the study utilized the total interpretive structural modeling (TISM) method to construct the conceptual model. Through spherical fuzzy analytical hierarchy process (SF-AHP) and spherical fuzzy decision-making trial and evaluation laboratory (SF-DEMATEL), the importance and influence of the indicators were determined. The results revealed that the most important indicators were "super-smart society" and "implementing circular economy to decrease environmental waste." The novelty of this research can be found in its application of the spherical fuzzy approach to examine the impacts of Society 5.0 smart technologies on achieving sustainable development, by addressing five major dimensions (governmental, economic, social, environmental, and technological). The findings could help managers to more effectively respond to the challenges of sustainable development by relying on Society 5.0.

Student residential apartment performance evaluation using integrated AHP-FCE method

Student residents' perception of the student residential apartment environment has gained greater prominence. Developing a performance evaluation framework from students' perspective is essential to post-occupancy management. In this study, an occupant-oriented performance evaluation framework was established based on a student residential apartment complex in the Netherlands through literature analysis, expert interviews and a focus group discussion with student resident representatives. The innovative framework, which comprises three levels of building performance attributes, divides the architectural design and building services performance attributes into two major categories. A questionnaire survey designed based on analytic hierarchy process (AHP) and fuzzy comprehensive evaluation (FCE) methods was used to evaluate the framework. Data on student residents' perceived importance of and satisfaction with the building performance attributes was collected by the survey. The analysis results show that building service performance attributes were considered less important to the student residents than architectural design attributes. Student residents' perceived priority weightings for various building performance attributes were compared by gender, educational level and length of stay. This study incorporates, in an innovative manner, student residents' perception into developing a performance evaluation framework for student residential apartments, and adopted the integrated AHP-FCE method to measure student residents’ perception on the overall building performance. The findings have important ramifications for the post-occupancy management stage.

Evaluation and Design of Reusable Takeaway Containers Based on the AHP–FCE Model

As a strong and effective alternative to disposable food boxes that cause serious pollution consequences, reusable takeaway containers are promising in terms of environmental protection. However, at present, in the service process of leasing, using, distribution, and recycling, reusable takeaway containers have many problems, such as incomplete cleaning, resulting in unhygienic conditions, repeated use of materials that are not safe enough, food spillage, leakage or theft of customer phone and address information due to exposed takeaway order labels, and wrong containers taken by customers. In addition, there is a lack of objective and comprehensive evaluation methods and systems to guide their design and improvement. In order to solve the current problems of reusable takeaway containers and explore a quantitative approach for evaluation of design solutions from the perspective of users, this paper analyzed user behaviors and needs through user interviews, questionnaires, user journey maps (UJM), and other methods. Analytic hierarchy process (AHP) and fuzzy comprehensive evaluation (FCE) were used to construct an evaluation model for the design of reusable takeaway containers, and it was calculated as a function of the survey dataset. The comprehensive index weight model was established, and the design indicators were sorted to obtain the priority of design elements. Three design schemes were proposed and calculated by combining questionnaire data and the FCE method to obtain the optimal Scheme B. The results showed that the combination of UJM and AHP–FCE method framework was suitable for scheme evaluation and design development, which could provide effective and detailed user evaluation for designers and guide the direction of product improvement.

Quantitative Evaluation Method for Construction Disturbance and Ecological Restoration of Waterway Engineering and Its Application

With the increasing emphasis on the ecology and environment of rivers, the construction of ecological waterway projects has become a development trend in China. In recent years, more and more attention has been paid to the qualitative and quantitative evaluation of the ecological effects of ecological waterway construction. Based on pressure-state-response (PSR) and driver-pressure-state-impact-response (DPSIR) logical frameworks, this paper established a state-pressure-impact-response (SPIR) conceptual model. The model took the river ecology and environment state as the main line, and described the disturbance pressure of the engineering construction on the river state, the impacts of the project on the river comprehensive function, and the positive responses taken in the full lifetime cycle of the project. The analytic hierarchy process (AHP) and fuzzy evaluation model were used to study the changes of the river ecosystem status after suffering from the construction pressure and taking positive responses. Taking the 12.5 m deep water waterway project in the Taicang-Nantong section of the lower reaches of the Yangtze River as an example, the disturbance on the ecology and environment at different stages of the project construction and the effort of relieving the negative impacts of the project on the ecology and environment were evaluated by the health level of the ecosystem. The paper can provide a scientific method for the evaluation of ecological projects in river ecosystems.

Research on design elements of household medical products for rhinitis based on AHP.

To improve the scientificity of household medical product design for rhinitis patients, this study used the analytic hierarchy process (AHP) to provide guidance for household medical product design strategy. In the process of design decision-making, the identification of user needs and the evaluation of the scheme depend heavily on the designer's experience and knowledge. The main contribution of this paper is to evaluate the design elements through the AHP method and apply it to the actual design work. This work can greatly reduce the risk in design decisions. First, the AHP model and evaluation matrix of design elements were established and sorted out by semantic analysis of users' research results. Second, an expert group was invited to score using the 1-9 scale method. Then, the geometric mean method was used to calculate the weight shares of different indicators so as to rank them. Finally, the strategy was proposed based on ranking indicator weights, and product design was carried out. The application of AHP can make the product design process more objective and rigorous. The design scheme of this study can provide references and ideas to promote the vigorous development of household medical products for rhinitis patients.

An Adaptive Multiexecutors Scheduling Algorithm Based on Heterogeneity for Cyberspace Mimic Defense

With the rapid development of network technology, the traditional defense of “mending the fold after the sheep have been stolen” cannot accurately prevent various potential threats and attacks in cyberspace. At the same time, cyberspace mimic defense (CMD) makes the system uncertain and dynamic in time and space to effectively defend against potential attacks. As the key technology of CMD, the scheduling algorithm still needs to be improved in reliability and active defense. Aiming at current problems, this paper first innovatively proposes a new heterogeneous measure algorithm HVTG combined with a vulnerability topology graph, which measures the heterogeneity of executor set in a fine-grained manner. Then, based on the historical confidence, heterogeneity, and minimum sleep time of the executor, we propose an adaptive multi-executors scheduling algorithm (HHAC) to better defend against various attacks. Finally, combining with Analytic Hierarchy Process and Fuzzy Comprehensive Evaluation, this research proposes a comprehensive evaluation model and fill in the gap of the evaluation model of the scheduling algorithm. Theoretical analysis and simulation results show that the HHAC performs well on the system dynamics, probability of system failure, and reliability, which is conducive to the development of CMD.

Usability Evaluation of in-Vehicle AR-HUD Interface Applying AHP-GRA

Usability is regarded to be a fundamental requirement for in-vehicle HMIs, and usability evaluation reflects the impact of the interface and the acceptance from the users. This study introduced a usability evaluation model of AR-HUD interface by applying grey analytic hierarchy process (AHP). First, based on the ameliorated PSSUQ (Post-Study System Usability Questionnaire), the usability evaluation system was modified and optimized according to the characteristics of AR-HUD. On this basis, the preference weights for evaluation indexes were calculated by AHP and the idea of group decision. Finally, the criteria of usability were integrated into grey relational degree by applying grey relational analysis (GRA) to obtain optimal design. A case study was conducted to demonstrate the applicability of the developed model to the usability evaluation of AR-HUD interface design. According to the existing AR-HUD interface design, 7 dimensions of design elements (A-G) and 18 interface prototypes (S1-S18) were selected by Taguchi orthogonal array test (TOAT). As the results indicated, the grey relational degree of S5 was 0.923, signifying that it was the optimal sample; and the results were also compared with entropy-TOPSIS to verify the feasibility of the proposed method. The grey-based AHP evaluation model can be used to evaluate the usability level of AR-HUD interface effectively, which may help designers achieve insights for design process and samples decision-making.

A novel fuzzy multi-factor navigational risk assessment method for ship route optimization in costal offshore wind farm waters

The navigational risk assessment in the waters of offshore wind farms (OWFs) is difficult to be quantified due to multiple factors, to solve this problem, this paper proposes a method of ship navigational risk assessment in the waters of offshore wind farms based on multi-factor fuzzy analytic hierarchy process. First, six influence factors of navigational risk in OWFs waters are analyzed, the analytic hierarchy process (AHP) and expert evaluation table are applied to determine the weights of influence factors. Then the fuzzy comprehensive evaluation is carried out to construct the method of navigational risk assessment. Finally, a comprehensive fuzzy multi-factor method of ship navigational risk assessment in OWFs waters is developed. Taking the OWFs in Changle of Fujian Province as an experimental case study, the navigational risk before and after sailing route optimization are comprehensively evaluated, and the evaluation results show that the value of navigational risk decrease from 3.1731 to 2.0409 after the sailing route optimization.

Sustainability assessment of individual-level solar energy poverty alleviation program-A case on Jinzhai County, China

In this paper we study the Solar Energy for Poverty Alleviation Program (SEPAP) in China, which aims to increase the 3,000 Yuan annually for poor people by installing solar panels. SEPAP was initially launched in 2014 and officially ended in 2020 when President Xi announced that absolute poverty was eliminated in China. During the 6 years, China built and put into operation 26.49 million kilowatts of solar PV systems, benefiting 1,472 counties, 138,091 villages, and 4.18 million poor households. We propose a sustainable assessment framework and apply the Analytic hierarchy process (AHP) and Fuzzy comprehensive evaluation method (FCEM) to evaluate individual-level SEPAP in Jinzhai County, China, based on the findings of 80 semi-structured interviews with professionals and poor households. When examining SEPAP sustainability, we discover that the economic dimension is the most crucial one, with income, employment, training for the poor, and solar panel quality being the most weighted sub-indicators. In 2021, SEPAP could increase by roughly 2,700 Yuan for poor households, which is 90% achieved the governmental goals. We obtain a “Medium-high” outcome for the individual-level SEPAP. We provide two policy recommendations for maintenance work that will help the poor maintain a steady income.

A new method for subsea tunnel site selection based on environmental bearing capacity.

Engineering site selection is an essential and systematic work in the early engineering construction stage. At present, the subsea tunnel site selection mainly depends on manual experience. There is still a lack of subsea tunnel site selection systems based on environmental impact. This study develops a comprehensive site selection evaluation system based on the analytic hierarchy process (AHP) and fuzzy evaluation method for the subsea tunnel site selection. It is a multi-indicator mathematical model evaluation system. On this basis, the ecological site selection method of the subsea tunnel is further studied, an indicator system for evaluating the environmental carrying capacity of the island is established, and the site selection results of the subsea tunnel based on the environmental indicators are obtained. We compared the site selection results of the two methods. The results show that the conventional method and the ecological site selection method based on environmental indicators can well carry out the site selection of subsea tunnels. The two methods take into account both the overall and local optimum of the subsea tunnel route and organically combine the overall and local objectives. This way provides a reference for the design and construction of the subsea tunnel in the future and points out the direction for the site selection of other large-scale projects with significant environmental impact.
