Embodiment Construction

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] The present invention proposes a distributed manufacturing scheduling method oriented to fixed-point output. The data field model is used to measure the task structure and equipment distribution status. The task structure measurement reflects the impact of the subsequent process on the candidate process, and the equipment distribution status measurement reflects the The local influence of equipment in the equipment network; using the reverse ...

Abstract

The invention provides a distributed manufacturing scheduling method for fixed-point output. The data field model is adopted to measure a task structure and an equipment distribution state, the task structure measurement reflects the influence of a subsequent process on an alternative process, and the equipment distribution state measurement reflects the local influence of equipment in an equipment network; By adopting a reverse scheduling method, starting from termination equipment and termination working procedures, equipment is reversely distributed for the working procedures, so that fixed-point output constraint of the task is guaranteed; Quantitative measurement of the established alternative processes and alternative devices can provide a basis for task scheduling, the scheduling process is simplified, and optimization of two aspects of tasks and device structures is considered.

Description

technical field [0001] The invention belongs to the technical field of distributed manufacturing specific to flexible processing, and is applicable to manufacturing scheduling optimization problems with a Dag (DirectedAcyclic Graph) task structure and fixed product output positions, and in particular relates to a distributed manufacturing scheduling method for fixed-point output. Background technique [0002] For general product processing tasks, DAG (Directed Acyclic Graph) is the main structure. In order to meet the flexible scheduling mode, the same process in the task can be processed on different equipment, and the same equipment can process different processes, and different equipment has different processing time for different processes. In addition, in order to meet the requirements of the distributed scheduling mode, the equipment is in a decentralized state and the equipment processing network is formed by the logistics relationship between the equipment. The fixe...
