Abstract:

The study is a comparative analysis of the costs and benefits from competing distributed and centralized ATARS architectures. The current DABSATARS structure is a distributed one a new architecture is postulated for deployment as a centralized ATARS system. Distributed and centralized ATARS are compared as to performance, cost, reliability, maintainability, vulnerability and growth potential. Performance and reliability are treated as constraints to be met equally be all architectures. Maintainability is included in cost. The cost analysis including cost sensitivities forms the bulk of the study. It is found that centralization of most sites is more costly than a distributed deployment and that the individual sites which contribute most to a cost advantage for centralization lie in high density terminal areas. A most significant finding is that centralized ATARS is inferior to distributed ATARS in vulnerability. The options are about equal in growth potential. Author
