以Web of Science数据库为数据源，检索29种运筹学领域核心期刊2007-2011年间所发表的20109篇文献，并运用OmniViz可视化数据分析工具和Excel软件，对文献进行聚类分析和词频分析，梳理和研究出近五年国际运筹学领域的学术热点。对文献主题词分析研究表明，价格问题、模糊理论以及供应链管理是目前运筹学中最热门的学术研究主题，其中生产领域有关并行调度的研究是目前的学术研究热点。根据论文关键词分析发现，数学规划仍是运筹学学科中最热门的研究分支，遗传算法、数据包络分析和神经网络等人工智能算法是运筹学领域的学术研究热点。
Research on the Academic Hotspots of International Operations Research
Takes the Web of Science as data source, statistically analyzes a total of 20109 research papers which have been retrieved from 29 opera-tions research journals published during the period of 2007-2011. In order to find out the research focus of the international operations research during the last five years, makes cluster analysis and word frequency analysis on these literatures by using OmniViz and Excel software. Analysis of the subject terms shows that price, fuzzy theory and supply chain management are the most popular research focus in current operations research field and parallel scheduling is one of the hotspots in the areas of production. The keywords analysis shows that mathematical programming is still the most popular branch of operations research disciplines. At the same time, artificial intelligence algorithms such as genetic algorithms, date envelopment analysis and neural networks are also research focus currently.
