The aim of this paper is to introduce a methodology for the design of progressive distributors in centralized lubrication systems by means of genetic algorithms. The paper focuses on the design of suitable ZP-A and ZP-B progressive distributors [7] for a centralized lubrication system with 16 lubrication points divided into 3 groups. Both types of the distributors are prefabricated modules, which are used to distribute lubricant to a given number of points in a sequential and progressive manner. ZP-A and ZP-B distributors can be composed of 3 types of sections of different sizes. Three sections is the minimum for both types of distributors. The following factors affect the way in which lubricant is divided in a distributor: the number of sections, section sizes, the interconnection of crosssection channels, the opening (closure) of or the interconnection of certain outlets in a section. The number and the organization of lubrication points determine the number and the hierarchical organization of progressive distributors in a lubrication system. In order to find suitable structures of ZP-A and ZP-B progressive distributors, an optimization program in Java [8] implementing a genetic algorithm has been developed. With the aid of this program, numerous structures of ZP-A and ZP-B distributors, as a result of a great variety of the interconnections of cross-section channels and many possible variations of section sizes, can be evaluated and a more suitable solution can be found much faster.
