This paper constructs a sustainability evaluation framework based on the extended VIKOR method, which can more accurately evaluate the sustainability of WET-PPP projects. The proposed method combines picture fuzzy similarity and traditional VIKOR method, considering uncertainties comprehensively and obtaining stable and feasible evaluation results.
This paper aims to construct a sustainability evaluation framework based on the extended VIsekriterijumska optimizacija i KOmpromisno Resenje (VIKOR) method under a picture fuzzy environment. First, a sustainability evaluation index system for water environment treatment public-private-partnership (WET-PPP) projects is constructed from the perspectives of the economy, engineering, environment, management, and society, including five criteria and 20 sub-criteria. The constructed index system considers engineering sustainability and management sustainability, and can thus more comprehensively evaluate the sustainability of the project and meet the requirements of the new economic environment. Second, a corresponding method for the sustainability evaluation of WET-PPP projects is proposed based on the picture fuzzy similarity-based VIKOR method. The main advantages of the proposed method include the following: (1) the sustainability evaluation process for WET-PPP projects involves linguistic terms and picture fuzzy numbers (PFNs), which can not only more comprehensively describe the uncertainty of human cognition and decision-making processes in the form of positive, neutral, and negative membership functions, but can also reduce the difficulty for decision-makers (DMs) to provide evaluation information; (2) the proposed evaluation method combines picture fuzzy similarity and the traditional VIKOR method, and can therefore not only obtain compromise solutions but can also ensure the stability and feasibility of the evaluation results. Finally, a case study of WET-PPP projects in China is provided to testify the feasibility and effectiveness of the constructed framework. The results indicate that the proposed framework can improve the accuracy of decision-making and can be applied for handling evaluation problems. (c) 2020 Elsevier Ltd. All rights reserved.

Data-driven multi-criteria decision support method for electric vehicle selection

Zhang-peng Tian, He-ming Liang, Ru-xin Nie, Xiao-kang Wang, Jian-qiang Wang

Summary: This paper proposes a sentiment analysis-based multi-criteria decision-making method to help consumers make EV purchase choices. The sentiment analysis results are transformed into hesitant intuitionistic fuzzy elements to derive the group opinion for each alternative. A comprehensive weighting method is developed to determine the weights of criteria. The ranking of candidate EV series can be obtained through the extended ORESTE method based on hesitant intuitionistic fuzzy Chebyshev distance. The results of sentiment analysis can also be useful for companies to explore consumers' demand for EVs.

Does endorsement rhetoric matter in citizen science?

Wei Wang, Yongyong Zhao, Yenchun Jim Wu, Mark Goh

Summary: This study examined the impact of rhetoric in endorsement texts on public willingness to participate in citizen science projects. Four types of endorsers were studied: professors, students, industrial researchers, and amateur researchers. Using a corpus of 1243 endorsement texts from 543 citizen science projects, the study empirically analyzed the effects of standalone techniques (ethos, pathos, and logos) and mixed-rhetoric techniques of persuasion. The results showed that pathos and logos were more effective than ethos. A mixed-rhetoric approach with a combination of 55% pathos and 45% logos maximized the appeal of citizen science projects, with an inverted U-shaped effect. The rhetorical strategies used by professors, students, and amateur researchers were similar, while industrial researchers had a different approach. However, the influence of endorsement strategies differed between professors (positive for logos only) and students (positive for pathos only) compared to amateur and industrial researchers (both pathos and logos were positive). Furthermore, endorsement rhetoric had a greater impact on humanities and social science projects compared to natural science projects.

Grey linguistic term sets for decision-making

Junliang Du, Naiming Xie, Sifeng Liu, Mark Goh

Summary: In the era of Big Data, decision-making has become more complex and uncertain. The fuzzy linguistic approach provides a closer representation to natural language and people's cognitive habits. The concept of grey linguistic term set (GLTS) is proposed to describe uncertain linguistic terms and can effectively support data generation, processing, and fusion in Big Data.

Incentive strategies for low-carbon supply chains with information updating of customer preferences

Mingyun Gao, Lixin Xia, Qinzi Xiao, Mark Goh

Summary: With the increasing climate disasters, consumers have a growing interest in low-carbon products. This paper analyzes incentive strategies for low-carbon supply chains considering the updating of low-carbon preferences. It describes information updating in low-carbon supply chains and analyzes the response decisions of the supply chain under the given incentive strategies. An optimal model of carbon reduction is designed for the government based on these decisions, and the best incentive strategies are optimized using a heuristic algorithm. The results show that cooperation among profit-driven supply chain members improves both their profits and carbon reduction efficiency.

Evaluating Economy Hotel Website Service Quality: A Hybrid Bounded Rationality Behavioral Decision Support Model

Zhiping Hou, Sangsang He, Ruxia Liang, Junbo Li, Ruilu Huang, Jianqiang Wang

Summary: Evaluation of hotel website service quality has received extensive attention, but previous studies have overlooked human hesitance and uncertainty in judgments, as well as the simultaneous consideration of hotel managers and customers' psychological behaviors. This study explores criteria for evaluating the service quality of economy hotel websites and proposes a hybrid evaluation model to address hesitation and uncertainty. The model utilizes probabilistic linguistic term sets to capture qualitative assessments and applies analytical network process to prioritize website features. It further integrates the TODIM-PROMETHEE II method to rank alternatives considering psychological factors. The effectiveness of the model is illustrated through a case study of economy hotel websites in China, highlighting service competence and customer relationship as the most important performance features. Conclusions and implications are derived from the results.

Summary: This study provides a decision model for making robust risk response decisions for single projects within project portfolios under uncertain project interdependencies. The model uses a four-stage interval optimization model based on a two-tier risk-project network. The results show that considering project interdependencies is more beneficial for decision makers compared to ignoring interdependencies or considering them with certainty.

A novel deep-learning framework for short-term prediction of cooling load in public buildings

Cairong Song, Haidong Yang, Xian-Bing Meng, Pan Yang, Jianyang Cai, Hao Bao, Kangkang Xu

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
