- Develop several ordering results between two order statistics arising from independent as well as interdependent heterogeneous random samples in a different stochastic sense.
- Develop several interesting sufficient conditions for which we can compare two complex systems (series, parallel, k-out-of-n), two claim amounts (smallest, largest), claimed by an insured person at a period according to their survival time or by their time of failure or by their claim amounts, respectively.
- Application of the established results in different fields of Applied Statistics, like Risk management, Auction theory, Reliability theory, Survival analysis, etc.
