“…A number of modeling and simulation techniques have been introduced to calculate the target probability of kill, particularly in the aircraft vulnerability domain (see Ball, ). These include variants of Markov Chain and Tree Diagram approaches (see, e.g., Pei & Song, ; Wang, Song, & Hu, ). Other studies have focused on targets with multiple overlapping redundant and nonredundant subsystem components (see Pei & Song, ; Pei, Li, & Song, ).…”

Determination of the gunfire probability of kill against a target requires two parameters to be taken into consideration: the likelihood of hitting the target (susceptibility) and the conditional probability of kill given a hit (vulnerability). Two commonly used methods for calculating the latter probability are (1) treating each hit upon the target independently, and (2) setting an exact number of hits to obtain a target kill. Each of these methods contains an implicit assumption about the probability distribution of the number of hits-to-kill. Method (1) assumes that the most likely kill scenario occurs with exactly one hit, whereas (2) implies that achieving a precise number of hits always results in a kill. These methods can produce significant differences in the predicted gun effectiveness, even if the mean number of hits-to-kill for each distribution is the same. We therefore introduce a new modeling approach with a more general distribution for the number of hits-to-kill. The approach is configurable to various classes of damage mechanism and is able to match both methods (1) and (2) with a suitable choice of parameter. We use this new approach to explore the influence of various damage accumulation models on the predicted effectiveness of weapon-target engagements.

Recently, much effort has been devoted to the study of aerodynamic performance analysis for the damaged aircraft. Sometimes, we are more concerned about the specific value of survivability of damaged aircraft, which allows the analysts to plan combat operations. How to relate aerodynamic performance degradation to survivability when the aircraft is damaged is important for military operation research. In this study, the maximum level flight velocity and one-on-one encounter model serve as the bridge combining aerodynamic computation and survivability analysis together, and an integrated survivability model of damaged aircraft is proposed. Two examples are provided to illustrate how the damaged wing affects the survivability of an aircraft. The proposed method is an attempt for quantitatively describing the relationship of aircraft survivability with the battle-induced damages affected by attach angel, flight altitudes, etc.

Aircraft combat survivability is defined as the capability of an aircraft to avoid or withstand a man-made hostile environment, which has been increasingly important. In order to give a rational calculation of aircraft combat survivability, an integrated method based on combination weighting and multiattribute intelligent grey target decision model is proposed. Firstly, an evaluation index system containing susceptibility index and vulnerability index as well as their subindexes is established. Then a multiattribute intelligent grey target decision model is introduced. A combination weighting method is brought up based on a modified AHP (analytic hierarchy process) method and the entropy method, offering a rational weight for various indexes. Finally, utilize the multiattribute intelligent grey target decision model to assess the aircraft combat survivability of aircraft, verified by a practical case of five aircraft. The results show that the proposed method is effective and has a great value in engineering application, which will provide useful references for other projects’ evaluation.
