Abstract

The invention discloses a cloud manufacturing service resource matching method based on an adaptive coefficient genetic algorithm. By calculating the value of the objective function of each individual in the population and judging the capacity limit, discarding individuals that do not meet the capacity requirements, calculating the adaptive coefficient and then calculating the cost The selection probability, crossover probability and mutation probability of round iterations, and carry out genetic evolution according to the aforementioned probability, generate a new population, and add new individuals to the population. According to the task requirements of cloud manufacturing users, the present invention solves the matching optimal resource service combination, ensures the lowest sum of the product of cost and time for all tasks, meets the capacity limit of resource services, and avoids waiting in line; improved genetic The algorithm has the advantages of strong robustness, fast convergence speed and the ability to avoid falling into local optimum, which not only significantly improves the diversity of the population, but also improves the accuracy of resource matching.

Description

technical field [0001] The invention relates to the technical field of cloud manufacturing, in particular to a method for matching cloud manufacturing service resources based on an adaptive coefficient genetic algorithm. Background technique [0002] Network manufacturing models such as traditional manufacturing grids and agile manufacturing have technical and model bottlenecks and cannot be promoted on a large scale. For this reason, combined with existing advanced manufacturing models and technologies and new technologies such as cloud computing, Internet of Things, virtualization, and service-oriented technology, the concept of cloud manufacturing was born. [0003] Cloud manufacturing adopts the cutting-edge concept of contemporary information technology (especially cloud computing), and expands the concept of "software as a service" to "manufacturing as a service", which will become an important model of my country's Industry 4.0. Due to the diversity, complexity, and ...
