A Method for Data Consistency of Petrochemical Enterprise Business Information Model

Abstract

The invention discloses a method for uniformizing the business information model data of petrochemical enterprises. The method comprises the following steps: (1) according to a specified production process, respectively establishing a PCS (process control system)-layer logistics topological model, an MES (manufacturing executive system)-layer logistics topological model and an ERP (enterprise resource planning)-layer logistics topological model so as to form multiple scales of logistics topological models corresponding to the production process; (2) establishing a mapping relation between every two adjacent layers in the multiple scales of logistics topological models; (3) constructing a business function module (relevant to the production process) and a business information model corresponding to the business function module; and(4) automatically correlating the business information model with the multiple scales of logistics topological models. According to the method, through the mapping among the multiple scales of logistics topological models, when the production process in a layer changes, related model data of other layers is automatically modified, so the consistency of basic data among the business information models is ensured under the condition that the consistency of data among different scales of logistics topological models, thereby greatly improving the efficiency of model management.

Description

technical field [0001] The invention relates to a petrochemical enterprise model consistent method, in particular to a petrochemical enterprise business information model data consistent method. Background technique [0002] Enterprise integration is a topic that has been widely studied and practiced in the world for many years. The purpose of studying this topic is to study how to organize the production and sales of enterprises, so that enterprises can develop and grow in the market competition. [0003] According to the international standard for enterprise control system integration modeling (Enterprise-Control System Integration) ISA-95 and the American Advanced Manufacturing Research Institute (Advanced Manufacturing Research, AMR), a three-tier enterprise integration model of ERP (Enterprise Resource Planning) / MES (Manufacturing Executive System) / PCS (Process Control System) was proposed. [0004] The PCS layer automatically controls the production equipment and monit...

Problems solved by technology

When each information model is directly oriented to modeling the production process, the change of process equipment must require that each related information model needs to update the model instance. For example, the scrapping of a certain device will cause all information models describing this type of device to be deleted at the same time. records, which is a cumbersome and error-prone task in large enterprise software systems

Especially in the current situation where software system providers (that is, software companies responsible for developing related systems) and software users (that is, petrochemical companies) have a clear division of labor, it is difficult for software system providers to track changes in the production process of software users in real time. However, software users cannot effectively update the process model due to unfamiliarity with the internal structure of the software system, which can easily lead to the inability of the software system to run effectively for a long time
