Embodiment Construction

[0045] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0046] In order to overcome the above-mentioned problems in the prior art, an embodiment of the present invention provides a scheduling method for loading and unloading tasks in an electrolysis workshop. In order to facilitate understanding, the relevant concepts that may be involved in this embodiment and subsequent embodiments are explained first:

[0047] The electrolysis workshop is composed of two parts: the unit area and the tank surface area. The unit area includes the anode preparation unit, the butt preparation unit, the cathode preparation unit, the cathode stripping unit and the preparation rack, and the tank area consists of a certain number of numbered Slot c...

Abstract

The invention provides a scheduling method and system for loading and unloading tasks in an electrolysis workshop. The scheduling method comprises the steps of performing iterative calculation using astate transition algorithm according to the obtained task execution sequence with the shortest scheduling route, and obtaining a new-generation task execution sequence group; and if the new-generation task execution sequence group satisfies a scheduling sequence constraint condition, obtaining a task execution sequence with the shortest scheduling route in the new-generation task execution sequence group. According to the invention, the operation of the production workshop is optimized and coordinated and the production cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of metallurgy, and more specifically, to a scheduling method and system for loading and unloading tank tasks in an electrolysis workshop. Background technique [0002] There are many approaches to the job shop scheduling problem. Widely used are mathematical programming method, artificial intelligence technology, artificial neural network technology, domain search technology (including simulated annealing method, genetic algorithm and tabu search, etc.), rule scheduling and other methods. At present, the field of scheduling is composed of two camps, one is the theoretical camp, focusing on the academic type of research; the other is the practical camp, focusing on the practicality of research. Among various workshop scheduling methods, rule scheduling with repair strategy or heuristic scheduling with repair strategy knowledge is more popular because it is simpler and closer to actual production. However, t...
