Study On The Visualization Of Lean Construction Domain Based On Knowledge Map

In recent years,China’s construction industry,still faces many obstacles,such as the overall low productivity level of the construction industry,the small scope of application of new methods and technologies,and the relatively rough management.In order to solve the problems in the development process of the construction industry and meet the requirements of lean management,many scholars and enterprise managers at home and abroad are constantly seeking methods to adjust and optimize the process of project management.Lean construction provides new ideas for solving the above problems,numerous research results have confirmed that the application of lean construction theory has made great contributions to cost saving,production process improvement,productivity improvement,customer satisfaction and business performance improvement,as well as sustainable development.Therefore,it is of great significance for construction enterprises and the construction industry to explore the evolution process,research focus and trends of lean construction theory for intuitive understanding and better application of this advanced management method and technology.There are many researches on lean construction theory at home and abroad,but few researches showed the konwledge structure,research focus and trends by visualization.There are also few studies on the knowledge body of lean construction.According to the understanding and application status of lean construction,we graphed the knowledge maps from the perspective of the discipline,the journals,references,and keywords by CiteSpaceV.The data used in the thesis were downloaded from Web of Science(WOS)which is a international authoritative database,and the retrieval time is setted from from 1990 to 2013.Through quantitative and qualitative analysis,the knowledge basis,research focus and research trend of this field are summarized,and the lean construction knowledge body framework is further constructed.The results of this thesis are positive to comprehensively understand the research status of lean construction,promote the application of lean construction in engineering practice,innovate engineering project management mode,and improve project mangement ability.
