LOGISTIC OPTIMIZATION OF THE COMPLEX MANUFACTURING SYSTEM WITH PARALLEL PRODUCTION LINES

The paper highlights the problem of mathematical modeling of a complex manufacturing system which is a potential synthetic representation of a real production environment. Production lines are parallel. Each production line consists of work stations which are placed serially along the predetermined trajectory. Each work station is equipped with the predefined tool used to manufacture the dedicated product. The system is controlled by means of heuristic algorithms to meet the manufacturing criteria. Equations of state illustrate the behavior of the system at every stage. The paper shows basic characteristics of current manufacturing systems emphasizing models for further optimization and simulation processing. First of all, the general background related to this topic is given. The second part of the paper focuses on the specific manufacturing system and suggests the ways of optimizing it to meet the given criteria with the use of heuristic algorithms.
