Abstract: This paper first summarized the connotation of manufacturing execution system (MES) intelligence,proposed the intelligent promotion scheme of MES in the petrochemical fields in terms of smart functions which included the promotion of the existing functions on the function and platform layer,the implementation of new functions and the integration of the existing functions and new functions.Second,this paper focused on the promotion of the support functions in the area of the optimization of the factory model in platform layer,intelligent computing service environment and events service center.The promotion of the current factory model was realized by using factory model extension method based on object-oriented analysis.By utilizing the corresponding selection of algorithms in agreement of problem and the solved component packaging technology,the environment of new intelligent computing serving was constructed.Based on the introduction of event service centric architecture,this paper proposed some methods,which can solve some key problems,such as building complex event matching model and rule engine etc.,in order to achieve two key functions,complex event checking and expert knowledge base.According to the provided integrating scheme,the three promoted function modules were integrated into the current platform.Thus,the function promotion of the current platform was achieved.Finally,the realization of MES intelligent function promotion was introduced with the aim for saving energy,reducing consumption and safe operation of ethylene plant in a certain petrochemical enterprise.And its practical application effect and economic benefit were shown as well.

Key words: intelligence, functional promotion, manufacturing execution system (MES)
