During the "14th Five-Year Plan" period,the overall supply of refined oil exceeds demand,the profit margin of the refining and chemical industry is in a downward trend,and the benefits of the engineering construction enterprises that provide support services has also declined.In order to improve the profitability of engineering construction enterprises,the cost of refining and chemical engineering projects become the key management object of the enterprise.Refining and chemical engineering projects are large in scale and complex in process.The entire construction process is long and cost management is difficult.This thesis takes the cost management of refining and chemical engineering project A of company C as research object.Firstly,the research background and significance are expounded,and the current situation of related research at home and abroad is introduced.Through the study on project life cycle and cost management theory,the theoretical basis is formed.Then,it introduces the cost situation of project A of company C.The problems existing in the cost management of project A are put forward,which mainly include four aspects.First,the cost estimate is inaccurate,resulting in a large gap between the approved amount of the project and the final budget.Second,the project cost planning is not taken into account in the design process,which leads to increased difficulty in purchasing and construction cost control.The third,the procurement process of materials and equipment required for the project is not well managed,and the procurement cost exceeds the estimated budget.The fourth is the ineffective cost control during the construction process.Then by dividing life cycle stages of project A,analyzing its cost composition and characteristics,the project life cycle cost management ideas are sorted out.In view of the problems existing in the project,the cost management improvement measures for each stage of the life cycle are proposed.They have strengthened a series of cost management efforts from cost forecasting,planning,control,accounting,analysis to assessment.Finally,in order to ensure the effective implementation of cost management,corresponding safeguard measures are put forward from the aspects of personnel training,cost regulation and system improvement.The purpose of this thesis is to study on the life cycle of refining and chemical engineering project A of company C,analyze the cost characteristics of different life cycle stages,and manage project costs in stages.In order to achieve the project management goals of reducing costs and ensuring quality,and improve the company’s market competitiveness in the context of economic downturn.Although this study is based on the actual situation of project A of company C,it has certain reference value for the cost management of construction projects with large scale,complex process and long construction period. |
