Embodiment Construction

[0088] The preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0089] This embodiment specifically implements the solution for the integration of production planning and scheduling described in the summary of the invention, and performs test simulation verification on the optimization results.

[0090] The flexible manufacturing system used for simulation in this embodiment is set up as follows, with a total of 800 machines distributed in 12 different workshops. These 12 workshops include 3 types of workshops including heat treatment workshop, assembly workshop and machining workshop. The same machine may also be distributed in different workshops. Almost all part routings have shop floor reentrancy issues. The experimental data adopts the data of the actual model A, which contains 2641 parts and 21306 processes.

[0091] Since the maximum production quantity per production month in actual prod...

Abstract

The invention relates to a workshop production plan and scheduling integrated method under a cross-workshop cooperation mode, which comprises the following steps of: firstly determining a narrowing workshop and a narrowing procedure; secondly, iterating, in each iteration process, pre-scheduling by adopting a dispatching rule-based scheduling method; and finally, regulating a production quantity according to a pre-scheduling result until outputting a scheduling result a corresponding production plan when the iteration is ended. According to the invention, the problem of unbalance of capability of production workshops can be effectively solved, the problem of transfer of a production task crossing the workshops is effectively solved, the production plan and the scheduling are integrated, and a production plane is given while a scheduling result is obtained.

Description

technical field [0001] The invention relates to a production planning and scheduling method of a manufacturing system, in particular to an integrated production planning and scheduling method for cross-workshop production tasks and the mixed problems of machining, assembly and heat treatment, belonging to the field of advanced manufacturing production control and scheduling optimization . Background technique [0002] In my country, most machinery manufacturing enterprises have established modern production lines, but at the same time, a large number of traditional equipment coexist with advanced equipment such as machining centers and CNC machine tools. Especially in large and medium-sized machinery manufacturing enterprises, the situation of multi-variety mixed production is very common. and will exist for a long time. In this context, the modeling and optimization methods of complex production process planning and scheduling problems face new challenges. The production p...
