| With the improvement in the level of opening up the oil industry and "going out" strategy,oil companies face internal and external severe environments. Competitive pressures are gradually improved.In such a situation, the oil companies want to survive and to develop, we must improve cost management, in order to increase market share.In recent years, although the oil companies have learned the advanced cost management experience,in terms of cost control and evaluation aspects of cost management has been a difficult problem.It haven’t established a kind of effective cost management system.Therefore, we conduct a research on the research institutions of oil companies and gradually optimize its cost management system have important practical significance.In this paper, W’s Institute of oil companies as the main object of study.It mainly base on cost management theory and operating cost management theory.It base on the existing cost management system of W’s institute.It combine with the W’s Academy’s production processes and management control activities. We propose optimize vision of cost management system.In this paper, we use the theory of cost management, combine with the production of W’s Institute business processes.We divide the production operations.On this basis, we optimize the main cost driver analysis by the elasticity of cost estimates, cost accounting and cost evaluation methods such as cost management system constituted.In this paper, we combine with cost management system to guarantee the smooth implementation of its measures and countermeasures. This optimized cost management system is a combination product of cost management theory, operating cost management theory and the actual situation of the current business.It is able to provide new initiatives and new methods for the cost management of W’s Institute.It will be an opportunity to improve business management, will help improve the overall management level.But with the internal and external environment changing,the strategic development, and other factors changing, W’s Company Institute cost management system design remains to be further optimized. |
