Chemical fiber industry plan production scheduling method and system

Abstract

The invention provides a planned production scheduling method and system for the chemical fiber industry. The planned production scheduling method comprises the following steps: obtaining a productionplan; generating a main plan according to the production unit, the machine table, the weight of the to-be-produced products of the machine table and the sequence of production arrangements; and issuing the main plan to the corresponding production unit and machine table according to the product specification, the mapping relationship between the process information and the production unit and themapping relationship between the production unit and the machine table. According to the planned production scheduling method, the management efficiency and the production efficiency of a chemical fiber enterprise are greatly improved by associating the product specification with the corresponding relation between the workshop and the unit and associating the corresponding relation between the unit and the machine table and automatically distributing the workshop, the unit and the machine table by automatically analyzing the product specification and the yield.

Description

technical field [0001] The invention belongs to the technical field of automatic production scheduling, and in particular relates to a method and system for planned production scheduling in the chemical fiber industry. Background technique [0002] Under the background of Intelligent Manufacturing Industry 4.0, as domestic chemical fiber companies continue to increase their smart manufacturing, they have taken advantage of the trend, despite realizing the digitization of production and operation data and the deep integration of industrialization and informatization. Although, the chemical fiber industry has made certain achievements in information construction such as industrial control, financial accounting, and material management. However, there are still some unsatisfactory aspects in the informatization construction of chemical fiber enterprises, such as: the lack of effective planning control and plan tracking of the production process in the field of chemical fiber pr...

Problems solved by technology

However, there are still some unsatisfactory aspects in the informatization construction of chemical fiber enterprises, such as: the lack of effective planning control and plan tracking of the production process in the field of chemical fiber production line production; there is the problem of isolated information islands, and the integration between existing information systems is poor

[0003] Nowadays, chemical fiber enterprises have a large number of orders every week, which is a typical production mode of multiple varieties and small batches. Production planning and scheduling are facing great challenges. At present, the production planning management of this enterprise mainly has the following problems: there is no standardized production management process, The division of labor among various departments is not clear, and there is a problem of shifting production between departments; production planning and production planning based on experience, production scheduling is chaotic, and order delivery is frequently delayed; machine scheduling is inaccurate, and machine utilization is low; , machine status, output, etc. lack real-time tracking, and the production response is poor; the forms of various production plans are visible at any time and cannot be traced back, and the timeliness and sharing of production information are poor

The management and control of the production site plan is weak, and the production notification is limited to mail, WeChat, telephone, etc., and the effective management is poor.
