Markov chain method for aircraft multiple hit vulnerability assessment based on vulnerable area decomposition

The purpose of this paper is developing an improved Markov chain method for vulnerability assessment of an aircraft which has arbitrary overlapping among critical components and probably receives multiple hits in a campaign. Since actual aircraft always has arbitrary components overlapping, an improved Markov chain method for aircraft multiple hit vulnerability assessment is proposed based on the aircraft vulnerable area decomposition method, and an universal algorithm is also offered for the solution of transition matrix, which contains two key parts, namely determining the matrix dimension and constructing the transition matrix. In the end, a numerical example is given. The result shows that the method is effective and feasible.
