Markov Models and Dynamic Analysis of ASW Effectiveness

Abstract: : The report presents methodology for evaluating ASW system effectiveness in dynamic operational contexts. It shows that conditional probability models may be generalized by using Markov modeling methods and suggests three models that include false contacts. Parameter estimation methods are given for Markov models and the results of experimentation with several methods are presented. Some of the methods use operational data not currently used in effectiveness modeling; hence, it is suggested that improved effectiveness modeling may be possible with Markov methods because more data can be used to estimate model parameters. State space structuring is investigated and results of numerical experimentation are given for different sets of states applied to the same set of data. (Data were generated by hypothetical non- Markov dynamic processes and a Monte Carlo simulation model).
