Embodiment 1

[0044] Such as figure 1 As shown, a method for adaptive scheduling of production workshop operations, the method includes the following steps:

[0045] S1: Divide the production workshop into a multi-layer tree structure, and decompose the scheduling plan parameters and the maximum allowable deviation threshold from top to bottom to reach each node;

[0046]S2: Obtain the scheduling plan parameters and execution status parameters of each leaf node, and calculate the execution deviation degree of each leaf node through the deviation degree measurement algorithm according to the scheduling plan parameters and execution status parameters of each leaf node;

[0047] S3: Compare the execution deviation of each leaf node with the maximum allowable deviation threshold of each leaf node, if the execution deviation does not exceed the maximum allowable deviation threshold, continue to execute the current scheduling plan, if the execution deviation exceeds the maximum allowable deviatio...

Embodiment 2

[0066] An adaptive scheduling device for production workshop operations, the device comprising:

[0067] Data collection unit: used to collect execution status parameters, and then send them to the hierarchical decision-making organization through the network;

[0068] Hierarchical decision-making body: deployed on the enterprise server, used to calculate the execution deviation of each node layer by layer from bottom to top, and compare the execution deviation of each node with the maximum allowable deviation threshold of the node, and make a decision to continue to execute the current schedule Plan, adjust the scheduling plan within the scope of the node or feed back to the adaptive scheduling decision of the upper node;

[0069] Decision output unit: used to output the adaptive scheduling decision made by the hierarchical decision-making mechanism to the corresponding control device.

[0070] Such as figure 2 As shown, in the specific implementation process, the hierarch...

Abstract

The invention discloses a manufacturing shop operation adaptive scheduling method and device. The method includes the following steps that: the execution deviation degree of each node is calculated through a deviation degree measurement algorithm according to scheduling plan parameters and execution state parameters of each node in a multi-layer tree structure; the execution deviation degree of each node is compared with a maximum allowable deviation threshold value of the nodes; and adaptive scheduling decisions about continuing to execute a current scheduling plan, adjusting a scheduling plan in the range of the node or giving feedback to a high-level node are made. According to the manufacturing shop operation adaptive scheduling method and device of the invention, the adaptive scheduling decisions are made through multi-level analysis, and therefore, problem of lag, inconsistency and incoordination in a production execution process can be solved, and adaptive scheduling adjustment on manufacturing shop operation can be realized according to the production process scheduling plan parameters and the real-time execution state parameters, and production efficiency can be improved.

Description

technical field [0001] The present invention relates to the field of workshop production scheduling of manufacturing enterprises, and more specifically, to a method and device for adaptive scheduling of production workshop operations. Background technique [0002] At present, the manufacturing industry is facing an urgent need for upgrading and transformation, and information technology is an important means for enterprises to achieve upgrading and transformation. Using information technology to implement management systems in enterprise manufacturing workshops, such as ERP (Enterprise Resource Plan) and MES (Manufacturing Execution System) to improve production efficiency, has also been implemented in many enterprises. Most of these systems contain the planning and scheduling module APS (Advanced Planning and Scheduling) to schedule and optimize the production process, and then send it to the workshop for execution. [0003] However, in actual production, the production pl...
