Research On Cost Management Optimization At The Construction Stage Of A Construction Enterprise Based On Lean Thinking

With the deepening of China’s economic society and socialist modernization economy,the competition of all walks of life is becoming more and more intense.By the commodity supply in construction market gradually turns to "oversupply",low price strategy has become a normal competition means in construction industry.Therefore,it is necessary for construction enterprises to take measures to improve management in order to cope with the problems of rising cost and decreasing profit caused by low production efficiency and serious waste of resources at the construction stage of projects.Some advanced scholars and enterprises abroad seek inspiration from the success of lean thinking that applied in manufacturing industry.They transplant lean thinking to construction industry and finally achieve success.Domestic enterprises should also take initiatives to embrace changes,learn from the strengths of others,integrate with the international community,introduce and learn the advanced foreign experience.They should change the existing construction cost management mode under the guidance of lean thinking,so as to meet customer needs,reduce process waste,decrease project cost and improve enterprise income.By means of literature research,this thesis studies the development course of lean thinking theory and engineering cost theory,also studies the application status of lean thinking theory that applied in engineering cost field.This thesis select A construction company as the object of case study,by the perspective of lean thinking,through brainstorming,questionnaire investigation,expert interview and other methods to excavate and analyze its problems that existing in cost management of construction stage,then to study these problems by the using of lean thinking,and finally give the solutions.This thesis consists of five parts.The first part is the introduction,mainly focus on research background,research significance,research ideas,research methods and main content.The second part is the literature review,which discusses the development,evolution and application history of lean thinking and construction engineering cost theory,as well as the theoretical development and practical application of lean thinking technology that applied in construction engineering cost field.The third part is the current situation about project cost management at the construction stage of A construction enterprise,which is explore and analyze the main problems facing the cost management at the construction stage of A construction enterprise based on lean thinking.The fourth part is the research on improvement of cost management at the construction stage of A construction enterprise based on lean thinking.By using JIT procurement,last planner system,activity-based costing method,6S management and other lean management tools or technologies to A construction enterprise at the construction stage,the improvement and mitigation about problems such as high procurement cost,large construction plan implementation deviation,high construction quota,low internal management level are deeply discussed.The fifth part,also the last part,is the research conclusion and prospect.This thesis is another exploration about using lean thinking to improve construction cost management of construction engineering,which promotes the development of related theories on construction cost management.It also provides a direction for A construction enterprise to improve its level of construction cost management,and provides a reference for others similar construction enterprise to carry out construction cost management on construction engineering.Due to the prudent operation and management of A construction enterprise,until the completion of the thesis,only part of the research results were applied to the cost management of construction stage in A construction enterprise,and most of the results are still in discussing and demonstrating.It’s really a great pity that this thesis does not continuously and quantitatively analyze the improvement of cost management by using research results to the construction stage of A construction enterprise.In addition,due to the limitation of time and space,the discussion of this thesis in some aspects may be deficient,and some practical details may not be considered,all of these needs to be studied in subsequent time.Finally,due to the limitations of research level and data collection ability,there may be some mistakes and errors in this thesis.
