Logistics center dump intelligent decision control system based on RFID and batch flow technologies and method

Abstract

The present invention discloses a logistics center dump intelligent decision control system and a method. The structure of the system comprises a goods allocation data collector, a cargo data collector, a dump working terminal and a dump batch decision system. A batch disassembling and scheduling method is designed by a batch flow technology, thereby reducing the single batch scale of the dump batch, and improving the rationality and accuracy of the dump batch scheduling. The execution case of the dump batch can be obtained real-timely by the assist of an RFID technology, thereby making up the disconnection problem of an information flow and the logistics in the previous operation. The control system and the method are suitable for improving the storage internal working efficiency, the automation levels and the cargo delivery service levels of various logistics parks, and possess very good economic benefits and market application popularization prospect.

Description

technical field [0001] The present invention relates to an intelligent decision-making system and method for dumping batches in the storage system of a logistics center based on RFID wireless radio frequency technology and batch flow technology, and especially relates to the implementation information acquisition of the status of the cargo area through RFID wireless radio frequency technology. The dump batch is decomposed by batch stream technology, and the decision-making method of realizing the intelligent decomposition and scheduling of the dump batch belongs to the field of intelligent information technology.

Problems solved by technology

However, its decision-making process relies entirely on manual decision-making, and the decision-making results affect the operation efficiency of the entire logistics center, and have a direct impact on the upstream and downstream of the supply chain. The phenomenon that the vehicles that have arrived at the logistics center are still out of stock, delays the delivery time, reduces the customer service level, and increases the operating cost of the logistics center. Its characteristics are as follows:

[0004] (1) The logistics center transfer decision-making problem is complex, and there are many factors affecting the logistics operation process of the logistics center. It is a typical combinatorial optimization problem, and its accuracy only depends on manual Experience is difficult to guarantee the optimization effect of decision-making results; the decision-making time is limited, the work intensity is high, and the sales order information is dynamic, and under the influence of other external factors, the decision-making problem presents dynamic uncertainty characteristics, which increases the complexity of decision-making; the current WMS system Provide data support for the decision-making process, such as inventory information, relevant document information, etc., but do not yet have the ability to assist decision-making, and fail to provide valuable auxiliary decision-making information to ease the difficulty of decision-making; decision-making support positions are highly dependent on personnel levels, which increases Work pressure on personnel, and at the same time bring unpredictable risks to the operation of the logistics center

[0005] (2) The dumping decision-making process is out of touch with the execution process. Since it is difficult to consider various influencing factors in manual decision-making, it is impossible to achieve refined management. Generally, a large batch of extensive Dump plan, decomposed and executed by forklift workers

As a result, there is a black box for managers and information systems during the execution process, and there is a phenomenon of asynchronous information flow and logistics

[0006] (3) The dumping decision leads to an obvious domino effect. Platform assignment, that is, specifying a loading platform for vehicles entering the park, is the final link in the decision-making process. Dump the impact of decision-making, the simpler the platform assignment rules, the more accurate the decision-making in the early stage, but at present, manual adjustments are usually required after the platform assignment, and it is difficult for the on-site dispatcher to grasp the overall information, and the assigned platform results are difficult to meet the overall optimization of the logistics center needs

However, the application of batch flow in the warehousing field not only decides the dismantling of the batch, but also decides the location of the batch and the location of the batch. Therefore, the model and solution method established in the current research are not fully applicable to the warehousing field.
