Designing an ACS by Applying Galvanic Coatings Based on Solving the Optimization Problem

An automated control system for the technological process of applying galvanic coatings to a variety of cathode parts of various shapes and sizes is considered based on solving the problem of finding the optimal arrangement of the parts in a galvanic bath to obtain coatings with the minimum value of criterion R—the ratio of the number of rejected parts Nreject to the total number of parts N placed on the suspension device. To solve the problem, a calculation-logical system is developed that uses the exhaustive enumeration method, the Gomory algorithm modified by the authors, and the branch-and-bound method. When solving the problem, the Gomory algorithm is found to be the best algorithm among the three methods in terms of performance. A two-level control system for the galvanic process in a bath with a suspension device is developed.
