A Configuration Optimization Method for Manufacturing System with Maximum Connectivity

Abstract

The invention provides a manufacturing system configuration optimization method for ensuring that the machine tool machining function has the highest connectedness, wherein the problem that in the prior art, the mass production capacity and flexible production capacity of a manufacturing system can not be simultaneously achieved is solved. The method includes the first step of obtaining process related information, the second step of setting up a similarity workpiece cluster according to machining functions, machining time and machining batches between workpieces in the process related information, the third step of encoding the workpieces according to the machining functions when the workpieces are machined in a workshop, the fourth step of arranging machine tools randomly, generating an encoding scheme, decoding the encoding scheme into an initial feasible solution, and setting the initial feasible solution as the current optimal solution, the fifth step of generating a feasible solution neighborhood of the current optimal solution according to the two-section ortho-position exchange strategy, the sixth step of calculating evaluation values of all feasible solutions in the neighborhood, the seventh step of selecting a solution in the neighborhood as the current optimal solution according to the taboo rule, and the eighth step of judging whether the current optimal solution is the global optimal solution or not.

Description

technical field [0001] The invention belongs to the field of advanced manufacturing, and particularly relates to a configuration optimization method of a manufacturing system that ensures maximum connectivity of machining functions of a machine tool. Background technique [0002] In the face of fierce global market competition and dynamic and ever-changing customer demands, the traditional manufacturing industry is faced with the huge challenge of how to respond quickly to market demands. The traditional rigid manufacturing system can improve efficiency through mass production. It is specially designed for a certain kind of workpiece rather than based on the changing production cycle, and has no scalability and variability; while the corresponding flexible manufacturing system can shorten product production. cycle, but the investment is too large, the redundancy of system functions is serious, and the capital payback period is too long, causing great cost pressure to the ent...
