摘要
流程优化对化工企业的重要性不言而喻,但由于化工企业流程复杂,投入产出、生产工况等随时都在变化,这使得传统的静态优化模型并不能很好地适合生产现状,从而不能给出有效的优化结果。而通过使用MES数据平台提供的实时数据和ERP平台提供的相关数据可以建立企业的在线动态模型,同时使用经典的GRG法可以求得企业当前工况下的最优解。试验表明该在线模型符合工程实际且取得了满意的实施效果。
It is self-evident that process optimization is very important to chemical engineering enterprises. Since the enterprise process is complicated, input/yield and productive conditions are changing at anytime, the traditional static optimization model is not well suitable for current status for getting effective optimized results. Through using real-time data provided by MES data platform and correlation data provided by ERP platform, the online dynamic model can be established for the enterprise. In addition, with classical GRG method, the optimal solution for current operation condition can be solved. The experiments show that the dynamic model meets actual conditions, and the implementing effects are satisfactory.
