Method for expressing relationship of process manufacturing procedures

Abstract

The invention relates to methods for expressing and operating relationships of process manufacturing procedures, wherein a series of matrix or vector to procedure relationships are designed for modeling in the method for expressing the relationships, specifically, the following matrixes or vectors are comprised, such as a procedure name vector, a procedure equipment quantity vector, a vector of product quantity in one batch, reachability matrixes among procedure equipment, transport time matrixes among procedures, a multi-process route matrix, reachability weight matrixes among the procedure equipment, processing starting time and ending time matrixes of products, and processing device distribution matrixes of the products in all procedures. The method for operating the relationships is used for operating the relationships of the procedures by using a matrix calculating manner. Compared with the prior art, the methods are simpler and general, and have better flexibility and expandability; and the integration degree of the expressing and the operating methods of the relationships of the procedures and an information system as well as a solution scheme is improved.

Description

technical field [0001] The invention belongs to the field of information management and information systems, and relates to a business process modeling method, in particular to a method for expressing process relationship in process manufacturing. Background technique [0002] With the development of information technology and the in-depth implementation of manufacturing information engineering, enterprises have more and more requirements for various information integration solutions or systems (such as enterprise resource planning ERP, manufacturing execution system MES and computer aided process design CAPP). high. These integrated solutions and systems all use process models to adapt to various application requirements such as production scheduling, process planning, process modeling and simulation, and enterprise business process reengineering. The expression of process relationship is the most basic and common content in the process modeling of the above applications. ...

Problems solved by technology

[0007] Among these methods, the advantage of the table is that the expression is simple and clear, but the disadvantage is that it limits the degree of freedom and flexibility of the operation; the network diagram can better express the process relationship with small scale and pre-determined operation tasks, but this static network structure Like the table, it has the disadvantage of insufficient flexibility, and when the scale of the task increases, the complexity of the network diagram will increase sharply, so its scalability is not good; business process modeling tools such as Petri nets or Gantt diagrams can be compared Describes process relationships well, but is inherently complex and requires researchers to have prior knowledge of the fundamentals associated with these tools

In addition, these methods all have a common defect, that is, the degree of integration with information systems is low, for example, it is difficult to support the production scheduling system to make globally optimized job scheduling
