Abstract

The invention discloses a scheduling method based on a multi-strategy water wave optimization algorithm. According to an operation mechanism of a water wave optimization algorithm and problem characteristics of three operations in the algorithm, the method mainly comprises the steps that for a continuous optimization problem, the water wave algorithm based on reverse learning and a covariance matrix adaptive evolution method is proposed, and refraction operation of the original water wave algorithm is replaced by updating a population with a covariance matrix to improve population diversity. In the zero idle flow shop scheduling problem, a skewness and variable coefficient combined method is provided for an initialized population to generate an initial sequence population to improve population stability, and a neighborhood search method based on different three operation operation attributes is provided. According to a distributed zero-idle flow shop scheduling problem with an assembly process, machine learning and variable neighborhood search are introduced, so that a proposed algorithm obtains a high-quality solution within limited time through training and reward in an iterative updating process. The method has the advantages of being simple in frame, easy to implement and clear in logic.

Description

technical field [0001] The invention belongs to the field of manufacturing production scheduling, and in particular relates to a scheduling method based on a multi-strategy water wave optimization algorithm. Background technique [0002] The production scheduling problem is a process that requires reasonable use and arrangement of existing resources within a limited time in order to maximize the production benefits of the enterprise. Usually, the classic flow shop scheduling problem regards the equipment capacity as infinite. However, in real life, it is necessary to arrange the production reasonably within the limited time of the equipment so that the workpiece is constrained by the equipment capacity during scheduling. Therefore, the equipment capacity constraint The job shop scheduling problem is more complex than the classic flow shop scheduling problem. At present, the core of solving the problem of improving resource utilization and production efficiency is to constru...
