Intelligent storage and distribution system optimization scheduling method based on polychromatic sets theory

Abstract

The invention discloses an intelligent storage and distribution system optimization scheduling method based on a polychromatic sets theory. The method belongs to a centralized and distributive combined mixed scheduling control method based on a multi-AGENT system. Under the condition of not influencing the normal work of other modules, the system has the advantages that a parallel processing effect and the robustness can be achieved, the modification and the extension are easy, and the like. The adaptability, the flexibility and the intellectuality of the system are enhanced. Through optimizing the system physical layer operating flow process and designing a reasonable system control layer decision algorithm, the real-time and dynamic scheduling of a storage and distribution system is realized. An RFID (Radio Frequency Identification) technology is utilized for collecting and processing system information, and the state of a material flow system is monitored in real time; the reference is provided for the management layer scheduling decision; the automation, the intelligence and the informatization of the information management and the control scheduling of the intelligent storage and distribution system are realized; and powerful technical support is provided for building the intelligent storage and distribution system based on Internet of Things.

Description

technical field [0001] The invention belongs to the technical field of storage and distribution center management, and in particular relates to an optimal scheduling method for an intelligent storage and distribution system based on multi-color set theory. Background technique [0002] Traditional control structures generally have two types: centralized and distributed. The centralized control structure system has a master-slave control relationship between the upper and lower control units. The sensor data flows from the bottom layer to the high-level management control unit, and the top-level management control unit generates instructions and sends them to the lower-level units. The main function of the upper control is to schedule and make decisions based on the knowledge submitted by the lower control. The advantage of the centralized control structure is that it can provide optimal scheduling because the upper controller has a global view. However, the centralized con...

Problems solved by technology

However, there are many disadvantages in the centralized control structure: the centralized control structure cannot provide a timely state description of the behavior, and the response speed of transmission and control flow is low; the structure is rigid, and it is difficult to add, modify and delete resources, which makes it impossible to expand or redesign the system ; Almost all decisions are made by the main controller, ignoring the interaction of the control unit, if the failure of the upper control unit will lead to the failure of the whole system

The disadvantage of the distributed control structure is that it ignores the interactive relationship between the upper and lower control units, and lacks forward-looking and global perspective.
