Częstość okresowych kontroli dla związanych z bezpieczeństwem układów sterowania maszynami : praktyczne zalecenia sposobów wyznaczania

In preventing the accidents due to improper operation of the control systems the periodical inspection of their functioning is of crucial importance. Therefore, the control system designer should specify how often the system should undergo the periodical inspection. The paper presents some recommendations for the determination of periodical inspection frequency of safety related control systems in machinery. The recommendations are based on simple and easy to use mathematical models which have been developed by adaptation and simplification of models used for the determination of maintenance policies of complex systems. Practical implementation of the proposed recommendation is illustrated on some actual case studies.
