Transformations of star-delta and delta-star reliability networks
Sheng‐De Wang, Cha-Hon Sun · IEEE Transactions on Reliability · 1996
It is an open problem whether there exists an equivalent transformation between star reliability networks and delta reliability networks. We provide: criteria to check if there exists any equivalent transformation when a delta-network or a star-network is given, and a criterion about a special star-network which has an unreliable center node and give an example to explain how to use it.
