Description

Method, device and storage medium for determining material delivery time Technical Field The application belongs to the field of warehouse logistics, and particularly relates to a method, a device and a storage medium for determining material distribution time. Background In the discrete manufacturing industry, especially in the production of assembly lines of automobiles, engineering machinery and the like, the on-time distribution of materials is a key for ensuring the production beat and improving the production efficiency. The production line needs to receive raw materials or parts required for subsequent processes at an appropriate time point according to a given production tact. Too late delivery can lead to material shortage and shutdown of the production line, and huge economic loss is caused. At present, many manufacturing enterprises still adopt a traditional material distribution scheduling mode, namely, production line workers, distribution staff and storage staff perform downlink communication to finish material distribution and online. However, the method has high manual requirements, and has the problems of large material distribution time estimated deviation, slow information transmission between a production line and a storage department, a distribution department and the like, and cannot meet the high-efficiency intelligent automatic production requirements of enterprises. Specifically, the material distribution mode using the manual communication as the core has two inherent defects that firstly, the distribution time calculation deviation is large, and the production stability is influenced. The calculation of material distribution time completely depends on personal experience of production line workers, but the production process has a plurality of variables, such as short equipment halt, time delay of a previous procedure, fluctuation of personnel operation efficiency and the like, so that manual estimation is difficult to accurately, line side congestion, material management confusion or production line halt waiting can be caused by calculation deviation, the continuity and stability of production are damaged, and the information transmission chain is long and low in efficiency, and cannot respond to production change in real time. The information transmission mode relying on manual communication is slow and low in speed and efficiency from a production line to a warehouse to a distribution link, when the production beat is dynamically adjusted or abnormal conditions occur, the information cannot be timely and accurately fed back to a logistics link, so that logistics scheduling and actual production demands are disjointed, distribution instructions are often based on outdated or distorted information, and the requirements of flexible production and quick response cannot be met.

To achieve the above object, an aspect of the present application provides a method for determining a material dispensing time, including: determining a second procedure with a configuration beat with the first procedure under the condition that the first procedure triggers the passing point signal, wherein the configuration beat represents a certain correlation between a material distribution time point of the second procedure and a sending time point of the passing point signal, and the passing point signal is generated when the first procedure is started or the first procedure is finished; for each second procedure, determining the beat time length P between the first procedure and the second procedure according to the type of the passing point signal; For each second procedure, determining a predicted starting time point of the second procedure based on the sending time point of the passing point signal and the beat time length P; determining the material dispensing time point of each second procedure according to the predicted starting time point of each second procedure; And determining the time point when the material warehouse of each second procedure should sort according to the time point when the material of each second procedure should be distributed. The method for determining the material distribution time further comprises the steps of triggering an initial passing point signal under the condition that a start command is acquired, determining the material latest distribution time point for the first working procedure according to the generation time point of the initial passing point signal, and controlling material distribution operation for the first working procedure according to the material latest distribution time point.
