The study of complex networks play an important role in many fields of technical. The system having no simple interconnections is called System with Complex Interconnection. In this paper, we have formulated optimum Accelerated life test(ALT) plan for a bridge network with independent components under ramp-stress loading scheme and Type-I censoring. In reliability theory, redundancy is understood as using additional units for replacement/substitution of failed units. A Bridge network structure is a kind of structural redundancy wherein failure of one component does not lead to failure of the system due to its redundant structure. Well known example of a bridge structure is Wheatstone bridge. The failure times of the system components are assumed to be exponential. The stress-life relationship is modeled using inverse power law, and cumulative exposure model is assumed to model the effect of changing stress. The optimal plan consists in finding out the optimum stress rate using D-optimality criterion. The method developed has been explained using a numerical example and sensitivity carried out.
