【摘要】 本文通过对锦州石化企业的生产运作系统分析,在锦州石化分公司现有方法的基础上,根据石化企业的基本特点,将投入产出分析同线性规划有机的结合起来,为锦州石化生产经营计划的编制提供了一种新的方法。应用线性规划建立数学模型来解决生产过程问题,即原油混炼、产品优化问题。从加工原料方面,通过对国内外石油资源市场以及我公司资源配置及加工方案的分析,确定最佳原油加工方案;另外从终端产品方面,对国内外石化产品市场进行了深入研究,针对我公司的实际情况,从地理环境、行业竞争以及市场营销方面进行全面分析并且应用系统工程解决问题的方法对生产运作系统进行了全面的系统分析,建立了系统的数学模型;并且对该系统模型进行了参数优化,而且对影响系统的参数进行了敏感性分析,找到了影响系统的最重要参数,最终得出了优化方案,从而达到了提高企业经济效益的目的。通过优化排产来指导企业高效产出,以市场为导向,科学化管理,实现效益最大化。最后,对企业今后的发展进行了战略性分析。更多还原

【Abstract】 Based on production planning method of Jinzhou Petro-Chemincal Company,this thesis combines the method of input-output analysis with linear programming organically according to the basic characteristics of Jinzhou Petro-Chemical Company and provides a new method for production planning in this company。Appling for liner program method to build mathematical model to solve problem of the productive process, such as, mixing refining crude oil and product optimization. On the side of processing raw material, to analyze the international and domestic crude oil market, decide on the best processing scheme and do its best to allocate the crude oil resources. On the other sides,to analyze deeply petrochemical products market from geographical environment, industry competition and marketing management. On the basis of meeting the requirements of production process,this method has closely banded together market requirements and stock control of products with production planning,which can improve the working efficiency,guarantee the practicality and adaptability of production planning and progressively improve the economic efficiency。On the basis of a systematic analysis of the production and operation system, a mathematical model of the system was built, hence the process parameters of planning system was optimized, furthermore, sensitive analysis to each parameter of the system was made and finally the most important process parameter of the system was found. It is concluded that the optimum program finds a way to develop product plan and will enlarge the revenue of enterprise. Followed the market orientation, concentrated its attention on improving economic benefits. At last, management strategy was analyzed in the future of enterprise.更多还原
