Problems solved by technology

In order to meet scheduling constraints or possible random changes, the production plan must include a certain capacity buffer or lead time buffer, which makes it difficult to optimize the manufacturing process; and once abnormal events such as order changes, machine failures, and material changes occur, the production plan cannot get timely corrections

Embodiment Construction

[0045] Below in conjunction with accompanying drawing, the present invention will be further described:

[0046] An integrated method for production planning and scheduling in an intelligent machining workshop, the method includes the following steps:

[0047] (1) System modeling: establish a physical system model of the intelligent workshop network composed of the physical layer, network layer and production control layer to provide basic conditions for the integration of production planning and scheduling;

[0048] (2) Data preparation: real-time collection, processing, transmission and storage of various status information on site, providing data preparation for decision-making of the planning and dispatching system;

[0049] (3) Order preparation: within each production planning cycle, analyze customer orders and convert them into specific machining orders;

[0050] (4) Production planning and scheduling: Under the existing constraints, use the necessary resources from the ...

Abstract

The invention discloses an intelligent machining workshop production planning and scheduling integration method, which belongs to the field of automated technical application. The method comprises thefollowing steps that: system modeling; data preparation; order form preparation; production planning and scheduling; virtual processing; dynamically monitoring; dynamically scheduling; revising a plan; and carrying out rolling optimization. Through production planning and scheduling integration under the support of an intelligent workshop network physical system, the closed loop of "production planning-production scheduling-production state information" under the dynamic environment of the workshop is realized, and the problem that an existing production planning and scheduling method is difficult in responding to various categories of dynamic events of environment (market) changes and workshop sites in time.

Description

technical field [0001] The invention relates to an integrated method for production planning and scheduling in an intelligent machining workshop, belonging to the technical field of automation. Background technique [0002] Production planning and scheduling has always been the core content of enterprise production management optimization. With the development of society and changes in market demand, multi-variety, small-batch, and order-oriented production has become the main production mode of most machining companies. The dynamics and uncertainty of the production system have been greatly improved, further increasing production planning and scheduling. difficulty. In the prior art, production planning and scheduling are carried out in a hierarchical manner, that is, the planning layer gives a plan, and the scheduling layer then schedules production according to the plan. In order to meet scheduling constraints or possible random changes, the production plan must include...
