MES system Learning

Mes system is the hotspot of the manufacturing enterprise Informationization, and the Unified Modeling Language UML is the standard language of object-oriented modeling, which plays an important role in software engineering. How the MES system is modeled in UML, today and we focus on the MES system UML modeling method, please see this article detailed introduction.

Unified Modeling Language is the standard language of object-oriented modeling, which plays an important role in software engineering. The implementation modeling process of MES system in a specific workshop is described, and the modeling method of UML in MES system is introduced, and the importance of developing MES system by UML is discussed. The modeling process of use case diagram and activity diagram in MES system is analyzed in detail.

Mes system is a hot spot in the informatization of manufacturing enterprises nowadays. Mes system fills the information fault of enterprise plan layer and workshop Process Control layer, can help organization production according to plan, and can control and record the complex production process of the product, make the plan and execution of the enterprise get a good connection, which is very meaningful to improve the management level and market competitiveness of the enterprise. Therefore, it is necessary to develop and implement the applicable MES system.

Modern software design is largely or completely dependent on the concept of an object, and the data is tightly bound to the operations that can be performed on that data through syntax. Object-oriented Analysis (OOA) is the process of defining problems based on objects, whereas object-oriented design (OOD) is the process of defining components, interfaces, objects, classes, properties, and operations. In general, start with candidates defined during analysis, and then add or change objects based on the need to refine the solution.

Mes system is a complex manufacturing information system, the following is a specific workshop to implement the MES case as the background of this paper to describe the MES modeling method and process based on UML.

Before the MES system is modeled in UML, the requirement must be clarified first. Through analysis, the functional requirements of this workshop MES system mainly include the following aspects:

(1) Material flow management. Manage a variety of production material resources to prepare, record and manage the distribution and handover process of materials before starting work.

(2) Allocation of production units. To manage the process of production units according to work order, order, batch, batch and task order, and to indicate the required operations in a timely manner based on the events occurring in the plant, and to change the scheduled schedule flexibly.

(3) Process management. Be able to obtain data from processed products and parameters, monitor production and automatically revise or provide decision support to the operators.

(4) Barcode management. Manage the use of barcodes and monitor the correct pasting of barcodes and their related product packing and inventory barcode management. Ensure that the barcode sequence of each batch of products is not heavy, no leakage, good number.

(5) Inventory management. Provide product batch registration, warehousing management and data reporting company and other functions.

(6) Performance analysis. Provide real-time reports of actual manufacturing situation, historical data and expected status, including resource utilization, product qualification rate, resource consumption and other data.
