Embodiment Construction

[0042] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, and the following embodiments do not constitute a limitation of the present invention.

[0043] The actual manufacturing environment is usually faced with many emergencies. In the task scheduling problem considering the arrival of new tasks, the initial scheduling scheme is first determined by assuming that no unexpected events occur in the cloud manufacturing system. During the execution of tasks based on the initial scheduling scheme, the cloud manufacturing platform often receives some unforeseen new tasks. Therefore, it is necessary to trigger the rescheduling strategy in time to assign services to new tasks, that is, to construct a new scheduling scheme and apply it to the cloud manufacturing system.

[0044] like figure 1 As shown, an embodiment of the present invention, a dynamic task-aware oriented cloud manufa...

Abstract

The invention discloses a dynamic task perception-oriented cloud manufacturing collaborative task scheduling method, which comprises the following steps of firstly, constructing a collaborative task scheduling model according to the proportion of tasks completed by a supply chain; generating an initial population as a current population when a new task arrives according to an original manufacturing task and an optional manufacturing service, dividing the current population into a plurality of sub-populations for subsequent iteration, and representing each collaborative task scheduling scheme in the current population by using matrix coding; and finally, solving is performed through an improved multi-population biogeography optimization algorithm, and fusing a multi-population strategy, a local search strategy and a cooperation mechanism, so that the task scheduling problem solving performance of the algorithm is improved. According to the method, a better scheduling scheme can be obtained in the scheduling stage and the re-scheduling stage.

Description

technical field [0001] The invention belongs to the technical field of cloud manufacturing task scheduling, and in particular relates to a dynamic task perception-oriented cloud manufacturing collaborative task scheduling method. Background technique [0002] Cloud manufacturing is based on advanced information technologies such as cloud computing and the Internet of Things, and aims to provide users with a safe, on-demand, reliable, and high-quality service-oriented new manufacturing method. In the cloud manufacturing environment, distributed manufacturing resources and manufacturing capabilities are virtualized and packaged as cloud services that can be centrally managed. The centralized management capabilities of services indicate that the cloud manufacturing platform can process batch tasks at the same time. In the actual manufacturing environment, the cloud manufacturing platform often receives batch tasks at the same time, most of which are complex and multi-granular, ...
