Abstract

The invention belongs to the technical field related to heat treatment production planning, and discloses a method for solving heat treatment furnace plan based on improved discrete teaching and learning algorithm, comprising the following steps: 1) establishing a mathematical model of heat treatment furnace plan; 2) generating different candidate sets of castings from the set of castings; 3) adopting an improved discrete teaching and learning algorithm to solve that mathematical model, thereby obtaining the furnace number plan of each casting candidate set, and selecting the optimal furnace number plan as the final furnace number plan; 4) judging whether that numb of furnaces currently planned reaches the set numb of furnaces; 5) obtaining a desired number of heat treatment furnace schedules. The mathematical model of the heat treatment furnace order planning proposed by the invention comprehensively considers three factors of furnace closing constraint, furnace order utilization rateand delivery time, and is closer to the actual production process of the enterprise, and the enterprise can reasonably optimize resources according to the above factors, ensure the optimum utilization of resources, and thereby reduce the production cost.

Description

technical field [0001] The invention belongs to the technical field related to heat treatment production planning, and more specifically relates to a method for solving heat treatment furnace schedule based on improved discrete teaching and learning algorithm. Background technique [0002] Heat treatment is an important process to ensure the structure and performance of castings in casting production. Since heat treatment is a high energy-consuming process and the processing time is long, it is often one of the bottleneck processes in casting production. In addition, in recent years, the market demand for castings has become more and more diversified, and foundry companies have shown a trend of small orders and diversified varieties. For foundry companies, it is necessary to design a reasonable heat treatment furnace plan calculation method to achieve heat treatment. The efficient formulation of production plans ensures the optimal utilization of resources, thereby reducing ...
