One-objective optimization model for a parallel-series system to determine thereliability of its components

Determining the reliability of a system is a popular issue inthe engineering design process. Clearly, higher reliabilitysystems are more valuable. On the other hand, thereliability of each system depends on the structure andreliability of its components. Therefore, in order to increasethe reliability of a system, the reliability of its componentscan be improved. In addition, to increase the reliability ofthe components of a system, it is necessary to consider itscosts. This paper deals with determining the amount ofincrease required for the reliability of a parallel-seriessystem components so that the reliability of the wholesystem is maximized and the cost of this increasing does notexceed a predetermined value. A numerical example ispresented for reviewing the results.
