Consensus Reaching with Minimum Cost of Informed Individuals and Time Constraints in Group Decision Making
The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link.Consensus reaching process (CRP) is important and present in a wide range of application areas. In practical CRP, the managers (e.g., enterprise) often hire some informed individuals (e.g., persuaders) to promote the efficiency of consensus reaching. This paper proposes a CRP with minimum cost of informed individuals and time constraint in large-scale group decision making (LSGDM) with bounded confidence effects. The consensus model with bounded confidence effects (CBC model) is formulated. Then, desirable properties of the CBC model are discussed to facilitate its resolution. Next, an extended Particle Swarm Optimization (PSO) algorithm is designed to solve the CBC model. Finally, a numerical analysis, a comparison analysis and a simulation analysis are provided to illustrate the feasibility and effectiveness of the proposed approach
Opinion dynamics in finance and business: A literature review and research opportunities
Opinion dynamics is an opinion evolution process of a group of agents, where the final opinion distribution tends to three stable states: consensus, polarization, and fragmentation. At present, the opinion dynamics models have been extensively studied in differrent fields. This paper provides a review of opinion dynamics in finance and business, such as, finance, marketing, e-commerce, politics, and group decision making. Furthermore, identified research challenges have been proposed to promote the future research of this topic
Retrospective Evaluation of New Chinese Diagnostic Scoring System for Disseminated Intravascular Coagulation.
To retrospectively validate the new Chinese DIC scoring system (CDSS).This study retrospectively collected the information of 619 patients (371 cases with non-hematologic malignancies, 248 cases with hematologic malignancies) who suspected of DIC in Wuhan Union Hospital during 2013-4 to 2014-6. We validated CDSS by comparing it with three leading scoring systems, from International Society on Thrombosis and Haemostasis (ISTH), Japanese Association for Acute Medicine (JAAM) and Japanese Ministry of Health and Welfare (JMHW), and evaluated its prognostic value by 28 days mortality, APACHE II and SOFA score.In non-hematologic malignancies, CDSS was more specific than JAAM (72.55% vs. 50.49%, p<0.05) and more sensitive than ISTH (77.07% vs. 62.03%, p<0.05). In hematologic malignancies, the area under the ROC curve of CDSS was larger than ISTH and JMHW (0.933 vs. 0.889, p<0.01 with ISTH, 0.944 vs. 0.845, p<0.01 with JMHW). In addition, the 28-day mortality rate, SOFA scores, APACHE II scores of DIC patients diagnosed by CDSS were significantly greater than non-DIC (P <0.05).We are the first group to propose CDSS. It emphasized the values of the clinical manifestations, the rapidly declining platelet count, APTT in the diagnosis of DIC and used D-dimer as the fibrin-related maker. DIC with hematological malignancies was treated as a special part. In this study we can see that CDSS displayed an acceptable property for the diagnosis of DIC with appropriate sensitivity and specificity, and also had a good prognostic value for DIC patients
