Workshop real-time scheduling method and device based on composite intelligent agent

Abstract

The embodiment of the invention discloses a workshop real-time scheduling method and device based on a composite intelligent agent relates to the technical field of workshop scheduling control, the requirements and quantity of operation carriers can be reduced, a central-node-free structure is adopted, a center node with high stability and high computing power is not needed. The method comprises astep of selecting a workpiece in a workpiece buffer area when an equipment intelligent agent detects that physical equipment is idle, a step of reading data in an RFID chip of a workpiece tray wherethe selected workpiece is located, activating a workpiece intelligent agent and generating a workpiece intelligent agent program corresponding to the selected workpiece according to the read data in the RFID chip, a step of allowing the generated workpiece intelligent agent to update the data in the RFID chip of the workpiece tray where the selected workpiece is located after the processing negotiation of a next process is completed, and a step of destroying the workpiece intelligent agent program corresponding to the selected workpiece and switching the workpiece intelligent agent into a non-activated state. The method and the device are suitable for a multi-intelligent-agent manufacturing workshop.

Description

technical field [0001] The invention relates to the technical field of workshop scheduling control, in particular to a method and device for real-time workshop scheduling based on a composite agent. Background technique [0002] With the development of computer and network technology, multi-agent manufacturing system has become a new type of intelligent manufacturing model, which is favored by more and more people and is considered to be an effective means to solve the current and future manufacturing difficulties. In the process of developing intelligent manufacturing in China, multi-agent manufacturing technology has become a topic that needs to be focused on. [0003] At present, some multi-agent manufacturing has been developed and applied, such as: [0004] The patent application publication number CN106094759A is called a real-time control method for workshop scheduling in a complex production environment. Workpiece intelligent body and equipment intelligent body wor...

Problems solved by technology

The disadvantage of this design is: the workpiece intelligent body lacks an effective computing carrier, and one or more additional computers are needed to provide computing power for the workpiece intelligent body; when the number of workshop orders continues to increase, the number of workpiece intelligent bodies continues to increase, which will It will consume a lot of computing resources and equipment. At the same time, multiple workpiece agents based on the same computing carrier are not conducive to system stability and maintenance operations.

The disadvantage of this design: the grouping of agents is based on a tree structure, which is controlled by the general manager, who controls a single agent
