A Large-Scale Group Decision Making Model Based on Trust Relationship and Social Network Updating

With the development of big data and social computing,large-scale group decisionmaking(LGDM)is nowmerging with social networks.Using social network analysis(SNA),this study proposes an LGDM consensus model that considers the trust relationship among decisionmakers(DMs).In the process of consensusmeasurement:the social network is constructed according to the social relationship among DMs,and the Louvain method is introduced to classify social networks to form subgroups.In this study,the weights of each decision maker and each subgroup are computed by comprehensive network weights and trust weights.In the process of consensus improvement:A feedback mechanism with four identification and two direction rules is designed to guide the consensus of the improvement process.Based on the trust relationship among DMs,the preferences are modified,and the corresponding social network is updated to accelerate the consensus.Compared with the previous research,the proposedmodel not only allows the subgroups to be reconstructed and updated during the adjustment process,but also improves the accuracy of the adjustment by the feedbackmechanism.Finally,an example analysis is conducted to verify the effectiveness and flexibility of the proposed method.Moreover,compared with previous studies,the superiority of the proposed method in solving the LGDM problem is highlighted.

Large-Scale Multi-Objective Optimization Algorithm Based on Weighted Overlapping Grouping of Decision Variables

The large-scale multi-objective optimization algorithm(LSMOA),based on the grouping of decision variables,is an advanced method for handling high-dimensional decision variables.However,in practical problems,the interaction among decision variables is intricate,leading to large group sizes and suboptimal optimization effects;hence a large-scale multi-objective optimization algorithm based on weighted overlapping grouping of decision variables(MOEAWOD)is proposed in this paper.Initially,the decision variables are perturbed and categorized into convergence and diversity variables;subsequently,the convergence variables are subdivided into groups based on the interactions among different decision variables.If the size of a group surpasses the set threshold,that group undergoes a process of weighting and overlapping grouping.Specifically,the interaction strength is evaluated based on the interaction frequency and number of objectives among various decision variables.The decision variable with the highest interaction in the group is identified and disregarded,and the remaining variables are then reclassified into subgroups.Finally,the decision variable with the strongest interaction is added to each subgroup.MOEAWOD minimizes the interactivity between different groups and maximizes the interactivity of decision variables within groups,which contributed to the optimized direction of convergence and diversity exploration with different groups.MOEAWOD was subjected to testing on 18 benchmark large-scale optimization problems,and the experimental results demonstrate the effectiveness of our methods.Compared with the other algorithms,our method is still at an advantage.

Non-Cooperative Behavior Management in Large-Scale Group Decision-Making Considering the Altruistic Behaviors of Experts and Its Application in Emergency Alternative Selection

Emergency decision-making problems usually involve many experts with different professional backgrounds and concerns,leading to non-cooperative behaviors during the consensus-reaching process.Many studies on noncooperative behavior management assumed that the maximumdegree of cooperation of experts is to totally accept the revisions suggested by the moderator,which restricted individuals with altruistic behaviors to make more contributions in the agreement-reaching process.In addition,when grouping a large group into subgroups by clustering methods,existing studies were based on the similarity of evaluation values or trust relationships among experts separately but did not consider them simultaneously.In this study,we introduce a clustering method considering the similarity of evaluation values and the trust relations of experts and then develop a consensusmodel taking into account the altruistic behaviors of experts.First,we cluster experts into subgroups by a constrained Kmeans clustering algorithm according to the opinion similarity and trust relationship of experts.Then,we calculate the weights of experts and clusters based on the centrality degrees of experts.Next,to enhance the quality of consensus reaching,we identify three kinds of non-cooperative behaviors and propose corresponding feedback mechanisms relying on the altruistic behaviors of experts.A numerical example is given to show the effectiveness and practicality of the proposed method in emergency decision-making.The study finds that integrating altruistic behavior analysis in group decision-making can safeguard the interests of experts and ensure the integrity of decision-making information.

Impacts and Adaptation: From the Points of View of Financial Management System in Enterprise Groups

The integration of international economy dominated wi th the financial market leads to fierce competition. This requires firms impleme nt modern corporate financial mechanism. From the view of the current situation of financial management in China, we demonstrates the differences in financial m anagement between Chinese enterprises and international companies by describing detailed case studies of typical large enterprises in China. To transform the enterprise management mechanism, the enterprise financial m echanism must be transformed accordingly. The basic ideas for its transformation and establishment include: 1. Changing the managerial ideology, that is, completing the ideological chan ge from the management of goods to the management of capital; 2. Establishing a scientific organizational mechanism for financial managemen t; 3. Establishing a mechanism for scientific management, supervision and assess ment; 4. Training high-level financial management personnel with modern management knowledge; 5. Dividing promotion center, distribution center, cost center and profit cen ter in financial division. In view of the above basic ideas and basic principles for the transformation and establishment of enterprise financial mechanism, we found that: the basic conte nt that needs transformation in the theory of China’s traditional enterprise fin ancial mechanism should include the content of finance main body, the content of financial objectives, the content of financial organizational structure and the content of environment for financial management. At the same time the following theories should be introduced, particularly the theories of capital time value, of risk in finance management and risk management, of the capital cost and capi tal structure, so as to establish a basic theoretical framework for the modern e nterprise financial mechanism. Based on the analyses, this paper discusses the impacts of economic globaliz ation to Chinese large enterprises and their financial management systems. From the current situation of Chinese companies’ financial management, this paper dem onstrates the adaptations to the differences in financial management of Chin ese enterprises with case study.

Foster and operate enterprises on large-scale basis to accept challenges from WTO accession

In the course of pushing forward the overall growth capacities of the mining industry and getting adapted to the tense competition after China抯 entry into WTO, it is quite necessary to speed up the process of fostering large state-owned coal group enter-prises. This strategical proposal is made on the basis of a comprehensive analysis of the main problems challenges faced by the coal mining industry is made on. The main prob-lems with Chinese coal mining industries discussed include: over-competition with a low convergence, severe waste and loss of mine resources with poor exploitation techniques, disordered operation with few industrial entry barriers, heavy welfare burdens from low socialization. The accession of WTO provide Chinese coal mining industry with chances to push forward the reforms and structural shift in the enterprises, expedite the estab-lishment and perfect of coal mining market mechanism, expand their international market share as well as introduce foreign investment, and with challenges from high technology, knowledge economy, and information revolution. The solutions to the foster of large-scale coal mining group enterprises, as well as the possible points to note and the policy pro-posal are advanced.

Large-Scale Group Decision Making:A Systematic Review and a Critical Analysis

The society in the digital transformation era demands new decision schemes such as e-democracy or based on social media.Such novel decision schemes require the participation of many experts/decision makers/stakeholders in the decision processes.As a result,large-scale group decision making(LSGDM)has attracted the attention of many researchers in the last decade and many studies have been conducted in order to face the challenges associated with the topic.Therefore,this paper aims at reviewing the most relevant studies about LSGDM,identifying the most profitable research trends and analyzing them from a critical point of view.To do so,the Web of Science database has been consulted by using different searches.From these results a total of 241 contributions were found and a selection process regarding language,type of contribution and actual relation with the studied topic was then carried out.The 87 contributions finally selected for this review have been analyzed from four points of view that have been highly remarked in the topic,such as the preference structure in which decision-makers’opinions are modeled,the group decision rules used to define the decision making process,the techniques applied to verify the quality of these models and their applications to real world problems solving.Afterwards,a critical analysis of the main limitations of the existing proposals is developed.Finally,taking into account these limitations,new research lines for LSGDM are proposed and the main challenges are stressed out.

MODELS OF THE SPATIAL EVOLUTION OF MULTI-PLANT ENTERPRISES

Since the 1970s, the studies on the geography of enterprise have become increasingly concerned with the spatial evolution of an enterprises in the West developed countries. However, little attention has so far been given to the spatial evolution of an enterprise in China. With China's ongoing economy and political reforms, a number of fundamental changes of enterprise behavior have occurred. These changes have certainly important influences on the evolution of industrial location. Therefore, there is a need for examining the spatial evolution of an enterprise in China. The purpose of the paper is to review the mapjor models of both the growth,and associated spatial evolution of an enterprise, with an illustrative case study of the HeaVy Automobile Enterprise Group of China. The paper is organized by three parts. The first examines the spoilal groWth and location adjustment of multi-plant enterprise. The second reviews mapjor models of the spatial evolution of an enterprise. And the third analyzes the spatial evolution, over a period of time, of a representative sample of the Heavy Automobile Enterprise Group of China, and illustrates the findings with case studies. It is suggested that the models of spatial evolution of an enterprise would provide more evidence about micro-mechanism for evolution of micro- regional economic systems.

行业企业参与高职专业群治理的行为识别——基于行业企业的扎根理论分析

行业企业是高职专业群治理的重要主体。为识别行业企业参与高职专业群治理的行为,对5家行业组织、9家企业进行半结构质性访谈,发现行业企业虽然具备承担育人的责任意识和参与协同治理的共识,但是在专业群治理中整体处于缺位状态。表现为行业存在治理意识淡薄、治理需求缺乏、治理意愿不强、治理行动乏力等行为表征;企业存在治理动机片面、治理动力不足、治理深度不够、治理行为单一等行为表征。因此,应通过提升行业企业的认知水平与治理能力、设计行业企业理性沟通协商机制、引入专业群柔性治理技术、增强专业群治理制度体系的敏捷性等举措,促进行业企业高质量参与高职专业群治理。

企业基础研究决策的同群效应及影响因素

以2013-2022年中国沪深A股制造业和信息技术业上市企业为样本,实证检验基础研究的同群效应的存在性、模仿路径及其影响因素。研究发现,企业基础研究决策受行业内其他企业的影响,即存在行业同群效应,其模仿路径呈现出一定的先内后外规律。企业所处的竞争地位越高,既往基础研究经验越丰富,其基础研究决策越容易受到行业同群的影响。相较于非国有企业,国有企业基础研究决策受同群企业影响程度较高。研究进一步发现,企业基础研究决策同群效应对企业创新绩效有正向促进作用。研究发现为更好地理解企业基础研究的外在驱动力,并为鼓励企业开展基础研究与完善中国基础研究政策体系提供思路参考。
