As/rs (automated storage and retrieval system) is mainly composed of high-rise three-dimensional shelves, roadway stackers, ground handling machinery and other hardware equipment, as well as computer management and monitoring system. Due to its high space utilization rate, strong inbound and outbound capacity, and the use of computers for control and management, which is conducive to the implementation of modern management, it has become an indispensable storage technology for enterprise logistics and production management, and has been paid more and more attention by enterprises. So what kind of intelligent system is the as/rs system of automated three-dimensional warehouse, and how does it help enterprises to carry out operation management and action? Now let the hegerls storage shelf manufacturer of hagris analyze it for you!
Intelligent as/rs is an intelligent module added on the basis of traditional as/rs. In the process of task scheduling, location allocation and queue optimization, according to the principle of task scheduling, location allocation strategy, queue optimization objectives and corresponding constraints, and establish the corresponding data model, use intelligent algorithm to solve, obtain the optimal solution, and improve the operation efficiency of automated three-dimensional warehouse system.
Composition of as/rs system
Automated three-dimensional warehouse is mainly composed of material storage system, as/rs warehousing system, as/rs management and monitoring system.
1) Material storage system
It is composed of the cargo compartment of the three-dimensional shelf and the material carrying device (material packaging, pallet, turnover box, etc.). The materials are placed regularly and stored neatly in the material bearing device, and the material bearing device is stored in the goods grid, forming a completed storage system.
2) As/rs warehousing system
The system undertakes the functions of goods access and warehouse entry and exit. It is usually composed of roadway stacker, inbound and outbound conveyor, loading and unloading machinery, etc. Roadway stacker is a crane operating in the narrow roadway of high-rise shelves. It can realize three movements: traveling along the track, vertical take-off and landing, and fork expansion and contraction. It is used to automatically store or take out goods from any cargo space on both sides of the shelves. According to the characteristics of the goods, the in and out conveyors can adopt conveyor belt conveyors, roller conveyors, chain drive conveyors, etc., which mainly send the goods to the stacking loading and unloading positions and the goods in and out of the warehouse. Loading and unloading machinery undertakes the work of loading or unloading goods in and out of the warehouse. It is generally composed of cranes, cranes, forklifts and other machinery.
3) As/rs management and monitoring system
It is composed of client computer, central control computer and electronic control system. The as/rs management and monitoring system not only manages and analyzes the material information, storage status and warehouse operation log of the three-dimensional warehouse, but also monitors the real-time operation status of the three-dimensional warehouse and timely schedules the configurable resources of the three-dimensional warehouse.
Intelligent as/rs system structure and process
1) System architecture
Automated three-dimensional warehouse is a comprehensive system integrating logistics, control and computer disciplines. The application methods of automated three-dimensional warehouse management and monitoring system can be divided into centralized, separated and distributed. At present, most projects in the world use distributed systems.
Wmos (warehouse management and operation system) architecture is usually divided into four parts: application layer, service layer, control layer and equipment layer. From the functional level, the automated three-dimensional warehouse system can be divided into three levels: management level, monitoring level and execution level.
Management: it is a computer management system, which has the functions of system setting, system information maintenance, product information maintenance, warehousing business, inventory query statistics, etc. The management is mainly responsible for the operation scheduling, material distribution, queue optimization, fault handling, etc. of the three-dimensional warehouse.
Monitoring layer: it is an important part of the automated three-dimensional warehouse system. It controls the logistics equipment according to the instructions from the management and completes the tasks transmitted by the management; On the other hand, the monitoring layer monitors the status of the stacker in real time in the form of animation, and feeds back the current information of the stacker to the management, providing a reference for engineers to schedule tasks.
Executive layer: it is composed of stacker embedded in PLC. The PLC in the stacker receives the instructions from the monitoring layer and performs various operations according to the instructions.
In fact, it can also be seen that the management is the core of intelligent as/rs, and its intelligent realization is mainly reflected in four important modules: intelligent assignment module of work tasks, intelligent processing module of material distribution, intelligent optimization module of work queue / path, and fault processing module. Each module plays a different role in different types of work processes.
▷ intelligent assignment module of operation tasks: according to the storage status of materials to be delivered and warehoused in each storage unit, reasonably allocate the delivery and warehousing operation tasks, so as to balance the workload of each storage unit and reduce the waiting time of operation tasks.
▷ material distribution intelligent processing module: according to the frequency of material in and out of the warehouse, physical characteristics, the current situation of in warehouse allocation, etc., reasonably allocate the warehouse location in and out of the warehouse, so as to improve the efficiency of storage unit in and out of the warehouse.
▷ job queue / path intelligent optimization module: optimize the queue sequence or the job path of the stacker according to the performance parameters of the warehousing system, so as to reduce the operation time of the stacker and improve the storage efficiency.
▷ intentional processing module: This module mainly deals with logical scheduling faults, rather than mechanical faults and communication faults. Deal with the logic fault in time and trace the root cause of the fault.
The architecture of intelligent as/rs is composed of as/rs intelligent scheduling method and as/rs inventory control method. The intelligent scheduling method of automated three-dimensional warehouse firstly determines the applicable intelligent scheduling scheme by using the principle of analytic hierarchy process according to the scale, structure, warehouse in and warehouse out system specification, task allocation strategy, material distribution and processing strategy and other information of the specific warehouse. Secondly, according to the intelligent scheduling scheme, the first step is to allocate job tasks from the overall level of the warehouse, and allocate the warehouse in and warehouse out tasks to specific storage units; The second step is to allocate storage locations for specific storage units; The third step is to optimize the batch job queue of each storage unit according to the result of location allocation in the previous step. Intelligent scheduling method is a distributed scheduling method, from global task allocation to location allocation and queue optimization of specific storage units.
2) Main process of intelligent as/rs system
▷ inbound and outbound operation process: in the inbound and outbound operation process, according to the details of the materials to be warehoused recorded in the disk assembly table and the details of the materials to be warehoused in the delivery order, analyze the storage of the corresponding materials in the three-dimensional warehouse in each storage unit, and assign tasks to each storage unit. After each storage unit obtains the corresponding inbound and outbound operation tasks, according to the material distribution of the storage unit, the material distribution intelligent processing module assigns a reasonable location to each operation task. The job queue / path intelligent optimization module gives initial priority to the batch job tasks waiting to be executed in the storage unit. The queue optimization module can optimize the batch task queue according to the optimization objectives to improve the storage efficiency.
▷ counting process: the so-called counting refers to the counting to determine the actual quantity, quality status and storage status of existing materials or commodities in the warehouse. It is the control feedback process of material management. The counting operation mode includes global counting and random counting. The global inventory has the characteristics of large inventory scale, long inventory cycle, consumption of resources in a single inventory, and impact on production. Random inventory has the characteristics of small inventory scale, short inventory cycle, less resource consumption and small impact in a single inventory. In view of the characteristics of random inventory, random inventory can be counted many times according to the size of the inventory, so as to improve the effective utilization rate of the warehouse and the consistency of storage data. When the detailed report of materials in stock is counted at the end of the year, a global inventory of the warehouse is required. The counting process involves material supply department, production department, warehouse management department, sales department and many other departments, so it can improve the efficiency of counting, save counting time and reduce the impact on production.
▷ stock transfer operation process: the focus of stock transfer operation is to filter the locations that need to be transferred. The intelligent material distribution processing module stores the same kind of materials in a centralized manner according to the requirements of relative concentration of materials, and selects the warehouse location that needs to be moved. After determining the storage location, the operation sequence of the storage location is clarified through the operation path optimization module to form a complete storage chain, reduce the no-load time of the stacker and improve the operation efficiency.
Automated warehouse is a discrete, dynamic, multi factor and multi-objective complex system. The intelligent management of as/rs is a complex system optimization problem. The traditional method not only takes a long time and costs high, but also is difficult to obtain the optimal solution. In this regard, Hergels storage shelf manufacturer combines modern intelligent optimization theory with as/rs application, which can improve space utilization and storage management level, reduce labor intensity, improve material scheduling level, speed up the turnover of reserve funds, and provide effective basis for production command and decision-making of enterprises.
