The Study On The Application Of The Method Of Analyze About The Decisions Of Operations Management To The Plastic Factory Of Daqing Petrochemical Co.

For a long time, the operations management of international large petrochemical enterprise always follows the administrative mode of the control economy times and the decisions for operations management lack of the scientific basis, so that economic benefits are not optimized and result in serious waste of human resource, material resource and financial resource. Up to the present, with the applications of Management Accounting, it is vital to find a production function model of enterprise. In the study, it makes the decisions for operations management more scientific and makes prove another complexion on decisions for production not scientific and makes economic benefits of enterprise optimized by analyzing the decisions for the operations management using Cost-profit-volume Analysis and Marginal Analysis.In the paper, it can be sure that the key factors of production for the production line A of The plastic factory of Daqing Petrochemical Co. are the output control and the maintenance costs by means of analysis of exterior condition and interior condition of The plastic factory of Daqing Petrochemical Co. In the first place, through construction method, on the ground of collection and clearing up datum of the plant for about 10 years, it can be found production function model by means of analysis of the trend chart of relation of the yield of plant and the load of output and the trend chart of relation of yield of plant and maintenance costs and the trend chart of relation of maintenance costs and the load of output. In the second place, it analyzed and validated the optimized results by means of distribution of correlative factors. Finally, it discussed the actual application of this model to the production line A of The plastic factory of Daqing Petrochemical Co., and offered my directive opinions on decisions of operationsmanagement to the production line A of The plastic factory of Daqing Petrochemical Co.In the paper, the method and results of the research can not only direct the decisions of operations management of the production line A of The plastic factory of Daqing Petrochemical Co., but also direct the decisions of operations management of the other five production lines of The plastic factory of Daqing Petrochemical Co. Thus the thoughts and results can be applied to each plant of Daqing Petrochemical Company, and have reference and spreading application values for all plants of Petro-China LTD. company, even all plants of international large petrochemical enterprise.
