Abstract

The invention relates to a cross-cell workpiece production path search method considering limited transportation capacity in the field of industrial production. Based on a two-stage ant colony optimization production path search algorithm, a transportation and production cooperation judgment mechanism is built by the aid of expected arrival time in pre-search, workpieces needed to be loaded on a transportation tool and the transportation sequence of the workpieces in the production process are determined, and process sorting orders are repaired to obtain a final production path. The cross-cell workpiece production path search method can solve the problems of machine idling and workpiece accumulated stacking in the production process of equipment manufacturing industry, machining and transportation are cooperatively optimized, production efficiency is improved, and completion time is shortened.

Description

technical field [0001] The invention relates to a cross-unit workpiece production route search method considering the limited transportation capacity in the field of equipment manufacturing industry, and belongs to the field of advanced manufacturing production control optimization. Background technique [0002] In recent decades, manufacturing systems have gradually transformed from traditional centralized environments to flexible distributed ones. In order to shorten delivery time, reduce inventory, reduce production costs, and improve product quality, Cellular Manufacturing System (Cellular Manufacturing System) came into being. Cell manufacturing is developed based on the idea of ​​Group Technology, which embodies the philosophy of lean production. In the cell manufacturing system, machines with different processing capabilities are grouped according to the similarity of workpiece technology to form manufacturing cells with relatively independent processing capabilities...
