Machining workshop scheduling and monitoring system and method

Abstract

The invention relates to a machining workshop scheduling and monitoring system and method. The system comprises a production scheduling and monitoring platform, a plurality of work stations and a plurality of handheld mobile data terminals, and is used for scheduling and monitoring the manufacturing process in which scheduling is carried out by an enterprise resource planning system and production is carried out by workshop equipment. According to the machining workshop scheduling and monitoring system and method, the monitoring and feedback for the dynamic optimal scheduling, the field production progress and the logistic movement in the dynamic manufacturing process are realized and the optimization of the scheduling result in the manufacturing process is realized, so that the machining workshop scheduling and monitoring system and method are suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of automation, and relates to a scheduling and monitoring system and method for a machining workshop. Background technique [0002] As we all know, Enterprise Resource Planning System (ERP) and Manufacturing Execution System (MES) both have certain functions of scheduling and controlling the workshop-level manufacturing process. However, since the manufacturing process involves many equipment and production tasks, as the manufacturing tasks are continuously processed and transported, the materials flow along the process route, constantly changing from raw materials to finished products, and the status of the entire production process changes rapidly; Various dynamic events occur, such as machine failures, order changes, processing time changes, etc. However, various existing manufacturing process management systems, which may be a module of the enterprise resource planning system or the manufacturing execu...

However, since the manufacturing process involves many equipment and production tasks, as the manufacturing tasks are continuously processed and transported, the materials flow along the process route, constantly changing from raw materials to finished products, and the state of the entire production process changes rapidly; Various dynamic events occur, such as machine failure, order change, processing time change, etc.

However, various existing manufacturing process management systems, which may be a module of the enterprise resource planning system or manufacturing execution system, or an independent system, often lack accurate and timely on-site information collection, lack of monitoring and feedback mechanisms, and make the existing optimization Scheduling decisions are difficult to implement effectively in a changing state space

At the same time, during the production process, the upper-level planning department cannot grasp the implementation of the workshop plan, the status of the work in progress, and the availability of materials in real time. Once a problem occurs, it will take a long time to find it, causing a lot of waste, and sometimes even affecting the delivery date

In addition, due to the inability to obtain on-site information in time, the system cannot deliver materials in a timely and accurate manner when there are problems with materials at each station, thus affecting the production progress
