Embodiment Construction

[0030] The present invention will be further described below in conjunction with specific embodiments. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0031] The purpose of the present invention is to provide a semiconductor production line scheduling method based on scheduling environment and tasks, including:

[0032] Based on the different scheduling environments and tasks, semiconductor manufacturing system scheduling is divided into static scheduling and dynamic scheduling.

[0033] (1) Static scheduling

[0034] Static scheduling refers to the process of forming an optimized scheduling scheme under the premise that the state of the manufacturing system and the processing tasks are determined. Static scheduling at a certain time t 0 The manufacturing system state U(t 0 ), determined workpiece information (specific processing task descripti...

Abstract

The invention discloses a semiconductor production line scheduling method based on a scheduling environment and a task. The method comprises the steps of performing scheduling classification on semiconductor production lines based on the scheduling environment and the task; and performing real-time scheduling on the semiconductor production line after scheduling classification. The invention has the beneficial effects that the positive influence is generated on the working condition of the production line, the queuing length of each kind of equipment and the waiting time of each card of workpieces are shortened, and then the operation efficiency of the whole production line is improved globally.

Description

technical field [0001] The invention relates to the technical field of semiconductor production, in particular to a semiconductor production line scheduling method based on scheduling environment and tasks. Background technique [0002] A semiconductor production line is a typical complex manufacturing system with a large number of processing equipment and an extremely complex process flow. There are usually more than a dozen types of products being processed at the same time on the same production line, which makes the competition for the right to use online equipment more intense; the scheduling plan and labor assignment strategy of the semiconductor production line will greatly affect the current production line conditions, scheduling strategies The advantages and disadvantages of each type of equipment will directly affect the queue length of each type of equipment, the waiting time of each card workpiece, and then affect the operating efficiency of the entire production...
