Abstract: In this paper, we have presented intuitionistic fuzzy optimisation technique to find out the optimum system reliability of complex systems subject to constraint on system cost. In general, the system costs as objective goal have not been stated clearly. Here the system cost is considered as intuitionistic fuzzy in nature. This imprecise reliability optimisation model is solved through the intuitionistic fuzzy optimisation method. It is shown that the intuititionistic fuzzy optimisation technique is more efficient in reliability optimisation than the analogous fuzzy technique. Examples are shown to illustrate the proposed method.
