Embodiment Construction

[0020] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples.

[0021] If there are 46 hearths, 23 heating mantles, 23 cooling mantles, 2 cranes, and 10 production plans to be scheduled, each different production sequence is a scheduling plan, and different scheduling plans are used for production Different production indicators will be obtained, and the purpose of production scheduling is to choose an optimal scheduling plan.

[0022] Step 1: Start the Genetic Algorithm Module

[0023] Module (2) numbers the 10 production plans to be scheduled from 1 to 10. Generate an initial population, each individual of the initial population represents a scheduling scheme, encoded with natural numbers, for example (1, 2, 3, 4, 5, 6, 7, 8, 9, 10) is an individual, representing a scheduling scheme ; and (10, 9, 8, 7, 6, 5, 4, 3, 2, 1) is another individual, representing another scheduling scheme, ...

Abstract

There is a cover annealing production and optimized excluding method in a computer. The method belongs to information technology field, refers to the application of genetic arithmetic and computer simulation in mantle quenched production. The character lies in that the method is made up of genetic arithmetic model and computer simulation quenched production model. The simulation model is used in simulating the whole quenche production process, the genetic arithmetic model optimizes the work scheme, the best scheme can be achieved through the interaction of the two models.

Description

technical field [0001] The invention belongs to the field of information technology, relates to automation technology, and in particular relates to a bell-type furnace annealing production optimization scheduling method. Background technique [0002] At present, the annealing workshop of most steel mills in China adopts the annealing method of the bell furnace group. The annealing is mainly divided into two stages of heating and cooling, and the cycle is long. The annealing cycle of the ordinary nitrogen-hydrogen bell furnace generally exceeds 70 hours. Even with the current relatively advanced full-hydrogen bell annealing process, the annealing cycle is more than 35 hours, which is a major energy consumer for metallurgical enterprises. The number of heating mantles and cooling mantles in the annealing workshop is usually designed according to a certain ratio, and the sum of the two numbers is equal to the total number of stoves. According to the current bell furnace produc...
