Embodiment Construction

[0049] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0050] The aviation manufacturing industry is a typical multi-variety, small-batch discrete manufacturing industry. The corresponding automatic production line of aviation parts must integrate resource status information such as manpower, equipment, materials, etc. production constraints, the generated production job plan needs to have a high degree of reference and accuracy. The production scheduling calculation problem of the aviation parts automatic production line is a combinatorial optimization problem, which is one of the keys to the efficient operation of the production line. A reasonable production operation plan requires an effective production scheduling solution method.

[0051] Automated production lines put forward higher...

Abstract

The invention discloses a multi-constraint scheduling calculation method and a device for an aviation part machining automatic production line. The method comprises the steps of acquiring process information and order task information of to-be-machined parts of an automatic production line; determining the priority of each process task in the order task information; sorting the process tasks according to the priorities of the process tasks on the premise of meeting various constraint conditions; on the premise that various constraint conditions are met, simulating the actual operation processof the automatic production line, obtaining a production scheduling calculation result, and the production scheduling calculation result comprises the predicted starting and ending time of each procedure task and a task list of equipment. Obviously, on the basis of solving all constraint conflicts, the priority of task scheduling is formulated, a process-level scheduling scheme meeting all conditions is generated and serves as a reference basis of the actual production process, and high practicability is achieved.

Description
