Railway Engineering Project Responsibility Cost The Lean Management Research

Large-scale construction enterprises as a special industry in the national economy,it is mainly engaged in engineering construction work in the field of system,by the competent administrative department for industry to the particularity of enterprise business license,he has to undertake the production of the project management process and project management system has its characteristics different from other industry,for the construction enterprises,cost management work throughout the whole process of construction management activities all the time,especially the lean management of the target responsibility cost of construction enterprise long-term development plays an important role.With the speeding up of the internationalization of market,the construction market competition is increasingly fierce,especially in the continuous improvement of the construction market management mechanism,the introduction of international advanced project management method and specification make construction engineering project management in domestic industry into the market completely,completely projects under the environment of fair competition in the economic benefits of landslide has become a problem to be solved in the industry,the problem affect the health of construction enterprises has become the bottleneck of sustainable development.In the process of project construction production management,many project managers do not really realize the importance of the lean management of engineering project cost,although some engineering projects in the prophase management of the project plan formulated the project responsibility cost management system,but in the concrete implementation process of the construction cost is finally didn't get effective control.Main reason is lack of project management for engineering project cost management system,there is no scientific and effective project cost management in lean goal decomposition to the whole unit,but only for performance appraisal and evaluation management.Project management system to become a mere formality,the lack of effective analysis was carried out on the key elements of the project cost management control,lead to project cost management method and related system in the execution of a project management become a mere formality,so I think only through the study of the lean management of project cost is the benefit maximization of construction enterprise.Project management involves many contents,respectively,the project management scope verification,cost analysis and cost management,safety and quality management,risk management,information system management,time management,human resource management,communication management,purchasing and contract management,standardized management,the civilized construction management,etc.The lean management of liability cost is the extension and supplement of other project management content,it is an important method to realize the objective of the project management.Lean project cost management process,that is,target cost control plan and the implementation of cost control plan the inspection plan is the main line,this paper studies the method based on cost management,the use of the principle of system theory,cybernetics and information theory,from the project cost control plan,the implementation of cost plan,cost plan,control the whole process of in-depth research.At the same time to the new double DC railway section PuJia project "as an example of large-scale railway projects cost management the lean management in the process of research and analysis of existing problems,and targeted to compile a complete project cost management solution.In the study of project cost the lean management process,stand at the height of the enterprise put forward some practical management methods,such as enterprise resource planning system dynamic consolidation,target responsibility cost and control the whole process of decomposition,the lean management researchers hope this article can give project cost to provide a reference and also to the enterprise to establish the target responsibility cost the lean management system to provide the certain help.
