Scoring rules are a popular method for aggregating rankings; they are frequently used in many settings, including social choice, information retrieval and sports. Scoring rules are parametrized by a vector of weights (the scoring vectors), one for each position, and declare as winner the candidate that maximizes the score obtained when summing up the weights corresponding to the position of each voter. It is well known that properly setting the weights is a crucial task, as different candidates can win with different scoring vectors. In this paper, we provide several methods to identify the winner considering all possible weights. We first propose VolumetricTop, a rule that ranks alternatives based on the hyper-polytope representing the set of weights that give the alternative the highest score, and provide a detailed analysis of the rule from the point-of-view of social choice theory. In order to overcome some of its limitations, we then propose two other methods: Volumetric-runoff, a rule that iteratively eliminates the alternative associated with the smallest region until a winner is found, and Volumetric-tournament, where alternatives are matched in pairwise comparisons; we provide several insights about these rules. Finally we provide some test cases of rank aggregation using the proposed methods.

评分规则是一种常用的排名汇总方法;在社会选择、信息检索和体育等许多场合都经常使用。评分规则的参数是权重向量(评分向量),每个位置一个权重向量,将每个投票者位置对应的权重相加得到的分数最大化的候选者即为获胜者。众所周知,正确设置权重是一项至关重要的任务,因为不同的候选人可以通过不同的评分向量获胜。在本文中,我们提供了几种方法来确定考虑到所有可能权重的获胜者。我们首先提出了 VolumetricTop,这是一种根据代表给备选方案带来最高分的权重集的超多面体对备选方案进行排名的规则,并从社会选择理论的角度对该规则进行了详细分析。为了克服它的一些局限性,我们随后提出了另外两种方法:卷积-径流(Volumetric-runoff)是一种迭代淘汰与最小区域相关的备选方案的规则,直到找到赢家为止;卷积-锦标赛(Volumetric-tournament)则是在成对比较中匹配备选方案;我们对这些规则提出了一些见解。最后,我们提供了一些使用所提方法进行等级聚合的测试案例。

The product–service system (PSS) is a strategic design approach proposed to address sustainability in socio-economic systems amidst rapid industrialization and transition. Evaluating the concept design of a PSS is a crucial and initial step prior to implementation. This study presents an innovative framework for evaluating concept designs of sustainable PSS based on a well-defined evaluation index system via integrating quality function deployment (QFD) and the technique for order preference by similarity to ideal solution (TOPSIS) while accommodating extended basic uncertain linguistic information (EBULI). Specifically, a QFD-based framework is first developed to identify the requirements of various stakeholders and then to establish the multi-dimensional criteria for evaluating sustainable PSS. Then, a House of Quality-based relationship matrix is introduced to determine the weights of criteria more accurately. Further, an adaptive consensus-reaching process method based on an expert weighting optimization model is proposed to ensure a collective outputs recognized by multiple involved stakeholders. Finally, an improved EBULI-based TOPSIS method is presented to determine the priority ranking of alternative sustainable PSS concepts. A case study on a car-sharing PSS project demonstrates the viability and effectiveness of the proposed QFD–TOPSIS integrated approach under EBULI settings. The alternative PSS concept design, which demonstrates relatively good performance in criteria of high importance, is selected as the most suitable option. Moreover, relevant comparative and sensitivity analyses reveal that the proposed approach exhibits superiorities in appropriate criteria elicitation, accurate weights determination, and high consensus ranking outputs.

产品服务系统(PSS)是一种战略设计方法,旨在解决快速工业化和转型期社会经济系统的可持续性问题。评估 PSS 的概念设计是实施前至关重要的第一步。本研究通过整合质量功能展开(QFD)和理想解相似度排序偏好技术(TOPSIS),提出了一个基于明确评价指标体系的创新框架,用于评价可持续 PSS 的概念设计,同时兼顾扩展的基本不确定语言信息(EBULI)。具体来说,首先开发了一个基于 QFD 的框架,以确定各利益相关方的要求,然后建立评估可持续 PSS 的多维标准。然后,引入基于质量屋的关系矩阵,以更准确地确定标准的权重。此外,还提出了一种基于专家权重优化模型的适应性共识达成过程方法,以确保获得多个利益相关者认可的集体产出。最后,提出了一种改进的基于 EBULI 的 TOPSIS 方法,用于确定可持续 PSS 备选概念的优先排序。一项关于汽车共享 PSS 项目的案例研究证明了所提出的 QFD-TOPSIS 综合方法在 EBULI 环境下的可行性和有效性。在重要标准方面表现相对较好的 PSS 概念设计被选为最合适的方案。此外,相关的比较和敏感性分析表明,建议的方法在适当的标准征询、准确的权重确定和高度一致的排序输出方面表现出优势。

In the consensus reaching process of group decision making (GDM), consensus measures do not require the consensus opinions of all decision makers. Meanwhile, unit adjustment cost is one of the important and often uncertain factors that affect consensus in GDM. Due to the uncertainty of unit adjustment costs, the moderator may not be able to provide each decision maker with an accurate unit adjustment cost. To overcome these problems, a novel class of group consensus decision models is proposed in this paper. First, fuzzy consensus measures are defined to make the consensus flexible using the specificity and coverage of the consensus granule. Secondly, to describe the uncertainty of the cost of unit adjustment, three uncertainty scenarios are created by the robust optimization approach is introduced. In the end, the feasibility and applicability of the method are verified by taking the classical GDM problem as an example, and sensitivity and comparative analyses are also performed.

在群体决策(GDM)的共识达成过程中,共识措施并不需要所有决策者的一致意见。同时,单位调整成本也是影响 GDM 达成共识的重要因素之一,而且往往具有不确定性。由于单位调整成本的不确定性,主持人可能无法为每个决策者提供准确的单位调整成本。为了克服这些问题,本文提出了一类新型的群体共识决策模型。首先,定义了模糊共识度量,利用共识颗粒的特异性和覆盖性使共识具有灵活性。其次,为了描述单位调整成本的不确定性,本文引入了鲁棒优化方法,创建了三种不确定性情景。最后,以经典的 GDM 问题为例,验证了该方法的可行性和适用性,并进行了灵敏度分析和比较分析。

Interventions involving simulated interactions aimed at mimicking real situations must be engaging to maximize their effectiveness. This study aimed to assess how a sample of middle school girls displayed behavioral and cognitive indicators of engagement when interacting with avatars representing game characters that were controlled by a human digital puppeteer. The simulation game, DRAMA-RAMA, is a component of an intervention intended to reduce at-risk girls' sexual and other risky behaviors. We used verbal/nonverbal behaviors and surveys to assess the game players' cognitive and behavioral involvement (N = 131). Participants perceived the game scenarios and interactions as realistic and the characters as similar to people in real life. Participants' behavior indicated their involvement and interest in interacting with the game characters. Finally, participants tended to be appropriate but not effective when attempting to advise/support the characters. These findings have implications for assessing successful operationalization of communication designs in interactive virtual learning environments.

Consistency and consensus are two key challenges under uncertain circumstances in pairwise comparison-based group decision-making (GDM), especially in a distributed preference relation (DPR) environment. In this paper, a comprehensive framework designed to tackle GDM problems evaluated by DPR is developed. First, after discussing two types of inconsistency in a complete DPR matrix: uncertainty-caused inconsistency and preference-caused inconsistency, two targeted optimization models to generate a consistent certain DPR matrix are proposed based on the definitions of stochastic additive strong/weak consistency and the similarity measure between DPRs. These models can effectively derive a DPR matrix closest to the original certain judgment by stochastic optimal allocation of uncertainties. Second, a new group consensus degree is introduced to measure the consensus in the group. Then a consensus improving model is given to reach an acceptable consensus by adjusting the DPR matrix of the decision maker (DM) with the least consensus degree. Third, the DMs’ weights are determined based on the expected consistency of the original DPR matrix by stochastic simulation instead of subjective judgment, and then the aggregated DPR matrix is obtained to derive a final solution using the weighted averaging operator. Finally, an automobile selection example is given to verify the validity and rationality of the proposed models.

A Water Resources Management Simulation–Optimization Model: Application of Graph-Based Hypergame Model in Water Supply Conflicts Resolution 水资源管理模拟优化模型:基于图形的超游戏模型在解决供水冲突中的应用

Abstract

To mitigate the unfavorable effects of excessive water resources consumption, mainly induced by poor performance of irrigation practices, efficient water resource management strategies are required. In response to this need, we have, in an innovative way, enhanced the water resources management (WRM) strategies by both considering the regional conditions with the graph model for a conflict resolution (GMCR) decision support system, and linking the irrigation concept and water resources allocation theory to develop a coupled WRM simulation–optimization model. Typically, implementation of the modified WRM strategies may cause local conflicts because of losing the original water rights. To improve the current irrigation water allocation system with the minimum objections, the hypergame theory was utilized to enhance the capabilities of traditional GMCR models by including the parties’ misunderstandings in the negotiation process and assessing the partial perceptions rather than crisp options. Moreover, by dynamic monitoring of available water resources and water consumption patterns, a WRM simulation model was developed, which is applicable in real agricultural conditions of multi-agricultural zones with multi-crop and intercropping systems and variable water supply sources. The genetic algorithm was utilized to allocate the water resources and determine optimal WRM strategies with the lowest irrigation water shortage.

摘要 为减轻主要因灌溉措施不力而造成的水资源过度消耗所带来的不利影响,需要制定高效的水资源管理战略。针对这一需求,我们以创新的方式改进了水资源管理策略,既考虑了冲突解决图模型(GMCR)决策支持系统的区域条件,又将灌溉概念和水资源分配理论联系起来,建立了水资源管理模拟-优化耦合模型。通常情况下,实施修改后的水资源管理策略可能会因失去原有水权而引发局部冲突。为了在反对意见最小的情况下改善目前的灌溉水分配制度,利用超博弈论增强了传统 GMCR 模型的能力,将各方在谈判过程中的误解包括在内,并评估了部分认知而非清晰的选项。此外,通过对可用水资源和用水模式的动态监测,建立了水资源管理模拟模型,该模型适用于多作物和间作系统以及供水来源可变的多农业区的实际农业条件。利用遗传算法分配水资源,并确定灌溉缺水量最小的最佳水资源管理策略。在阿曼的常规农业区对所建议框架的效率进行了评估。所建议的战略不仅解决了最佳水资源管理战略实施过程中的地方冲突,还展示了减少水资源短缺这一严重环境问题的巨大潜力。

In response to this need, we have, in an innovative way, enhanced the water resources management (WRM) strategies by both considering the regional conditions with the graph model for a conflict resolution (GMCR) decision support system, and linking the irrigation concept and water resources allocation theory to develop a coupled WRM simulation–optimization model. Typically, implementation of the modified WRM strategies may cause local conflicts because of losing the original water rights. To improve the current irrigation water allocation system with the minimum objections, the hypergame theory was utilized to enhance the capabilities of traditional GMCR models by including the parties’ misunderstandings in the negotiation process and assessing the partial perceptions rather than crisp options. Moreover, by dynamic monitoring of available water resources and water consumption patterns, a WRM simulation model was developed, which is applicable in real agricultural conditions of multi-agricultural zones with multi-crop and intercropping systems and variable water supply sources. The genetic algorithm was utilized to allocate the water resources and determine optimal WRM strategies with the lowest irrigation water shortage. The efficiency of the proposed framework was assessed in conventional agricultural zones in Oman. The recommended strategies not only address local conflicts during the implementation of optimal WRM strategies, but also demonstrate significant potential to reduce the water shortage as a serious environmental concern.</p>","PeriodicalId":47553,"journal":{"name":"Group Decision and Negotiation","volume":"7 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2023-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139055663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
