Fuzzy Reliability of Series-Parallel System Using UGF and Hesitant Fuzzy Set

In this work, authors deal with a complex system having combination of series-parallel system with five elements and system is done if one element of parallel system is done the hesitant fuzzy reliability of the system has been evaluated using Weibull distribution and universal generating function and averaging operator. Further score function having equal weight has been applied with the help of an example, in the end of the paper to demonstrate the proposed technique.
