Abstract

The invention provides a scheduling method for a complete set of orders with switching time. The scheduling method comprises the following steps: a) establishing a mathematical model of a complete setof order scheduling problem; b) calculating by utilizing an artificial bee colony algorithm with a neighborhood structure according to the established mathematical model: setting a population size, aneighborhood search algebra and an upper limit of an unimproved algebra; initializing a population according to the coding scheme; adopting a semi-active decoding mode to obtain an individual fitnessvalue; searching and occupying a high-quality honey source, and sharing honey source information with the following bees; selecting an employed bee and collecting honey by following the employed bee;judging the number of individual improvements of the employed bees; when an individual better than the current employed bee appears in the filial generation, replacing the current employed bee individual; and if the termination condition is not met, continuing to optimize. Compared with the prior art, the scheduling method has the advantages that enterprises or factories can formulate reasonableproduction strategies under the conditions of given resources and constraints, the scheduling efficiency is improved, and the operation cost of the enterprises is reduced.

Description

technical field [0001] The invention relates to the technical field of production and manufacturing, in particular to a scheduling method for complete orders with switching time. Background technique [0002] With the rise and development of new manufacturing concepts such as China's intelligent manufacturing 2025 and industry 4.0, the manufacturing execution management system (Manufacturing Execution System, MES) serves as a bridge connecting the enterprise resource management (ERP) and the manufacturing layer. It plays an indispensable role in the process of information interaction between layers. Among them, production scheduling, as a key link in the MES layer, is crucial to the operation and benefits of the enterprise. [0003] In the prior art, with the development of the assembly manufacturing industry, the production assembly tends to develop towards diversification and customization. Different from the traditional scheduling problem, the workpiece matching problem...
