Improving reliability system in radar model based on two parameters Weibull distribution

In this paper, the two parameters Weibull distribution lifetime model has been used to improve the reliability of a system in radar structure. This model is flexible to any lifetime data analysis and describing all stages of failure rate. Redundant and reduction methods of improving the system reliability are provided, including cold, hot, and imperfect methods. The lifetimes of units are assumed to be independent and non-identical components. To distinguish between different methods, we computed the mean time to failure and γ -fractiles. Reliability equivalence factors are also derived. Simulation examples were given to differentiate between different improving methods.
