Location allocation and scheduling method for high-density three-dimensional warehouse based on digital twin

Abstract

The invention discloses a digital twin-based high-density three-dimensional warehouse location allocation and scheduling method. Inbound planning is based on the principle of the shortest warehousing and scheduling path, and each step of the warehousing planning judges whether it conflicts with the delivery time of the goods stored in the target lane, effectively solving the problems of order congestion and conflicts between warehouse location allocation and equipment scheduling . The digital twin-based high-density three-dimensional warehouse location allocation and scheduling method provided by the present invention uses the physical simulation platform to obtain order information in advance to plan the location and equipment in advance, and realizes the coordination between the digital model of the high-density three-dimensional warehouse and the on-site physical equipment. Instruction synchronization and information transmission can truly simulate the actual production process, so that the simulation analysis and verification test results are sufficiently credible and convincing, and then provide effective guidance for real high-density three-dimensional warehouse location allocation and equipment scheduling, which will help It is used to analyze and solve the problems of conflicts in warehouse location allocation and equipment scheduling and order congestion.

Description

technical field [0001] The invention relates to the technical field of warehouse management, in particular to a digital twin-based high-density three-dimensional warehouse location allocation and scheduling method. Background technique [0002] At present, ordinary three-dimensional warehouses need to use a stacker in the middle of two single-row shelves for storage management. For example, 5 single-row shelves must use 4 stackers for storage management. With the development of the logistics industry, high-density three-dimensional warehouses have emerged. The high-density three-dimensional warehouse is a combination of shelves. The shuttle rack in the middle is managed by the shuttle car and the stacker. The single-row shelves on both sides are managed by the corresponding stacker, which can greatly increase the space of the three-dimensional warehouse. utilization rate. [0003] The high-density three-dimensional warehouse under the existing technology mainly allocates t...

Problems solved by technology

The biggest disadvantages are: (1) The existing system is basically in the state of responding to order demands in real time, and cannot obtain order information in batches in advance and plan storage locations and equipment in advance. Various production emergencies are prone to occur and production tasks cannot be completed on time , the system flexibility is poor; (2) the existing system lacks efficient storage location allocation and equipment scheduling algorithms, and also lacks the feasibility and efficiency analysis methods of scheduling schemes, which can easily lead to equipment being unable to respond to inbound and outbound demands in a timely manner, resulting in order congestion; (3 ) The existing design method fails to integrate the digital model of the high-density three-dimensional warehouse with the upper management and control system, and cannot realize the dynamic simulation test of "the management and control system issues production instructions to the digital model of the high-density three-dimensional warehouse"; at the same time, it cannot Realize the instruction synchronization and information transmission between the digital model of the high-density three-dimensional warehouse and the physical equipment on site, which cannot truly simulate the actual production process, so that the simulation analysis and verification test results do not have sufficient credibility and persuasiveness
