Abstract : A Markov model considering the possible states of an aggressor in an air defense system is presented. This model considers an air defense system as consisting of two basic operations; detection and neutralization. Two types of costs, construction and losses, are related by means of a total cost function. The criterion for optimization is the minimization of the total cost function with respect to the pertinent transition probabilities. Examples illustrating the synthesis for a basic system are given, using various cost functions and utilizing alternative techniques for optimization, i.e., factorial method, univariate method, and the method of steepest descent. The techniques and results of these preliminary investigations are evaluated and an example of the synthesis is illustrated, including those modifications shown to be necessary by the evaluation. The Markov model is extended to allow division of basic operations so as to form multiple lines of defense and an example illustrating the synthesis for a doubleline system is given. (Author)
