Analysis of weapon systems subject to correlative cause failures based on Markov process

The mean time to failure of weapon systems subject to common cause failures and load sharing cause failures is analyzed based on Markov process. Aim at the weapon systems that common cause failures and load sharing cause failures appear at the same time, the example is analyzed. The result which the correlative cause failure is considering or not are contrasted and analyzed. The results show that the Analysis of Weapon systems subject to correlative cause failures is very important.
