A Hierarchical Weighing Additive Summation Method for the Evaluation ofWarships' Platform Characteristics

In this paper，an evaluation model for warships' platform characteristics is developed. Specifically，an evaluation index system is first established through the analytic hierarchy process（AHP），based on which the complicated multi-project and multi-object system is analyzed quantitatively. The obtained assessment data is then examined using the fuzzy mathematical theory model，and the weight of each index is determined with AHP. Finally，the hierarchical weighed summation is calculated for the purpose of comprehensive evaluation for the performance of warships. To validate the proposed method，3 design proposals for a particular warship model are evaluated respectively. The results indicate that the presented approach is suitable for analyzing complicated systems with multi-project，multi-object，and multi-level hierarchies，and is feasible for the practical design and scheme selection for various warships.
