Study on the Methods of Maintainability Allocation of Under Water Vehicle

Based on the analysis of the common method of the maintainability allocation, and for the sake of overcome the limitation of the common method--“maintainability allocation method which is pro rata for the failure rate and characteristic of design” when the design character is feckly, the method of “maintainability allocation method which is pro rata for the failure rate and characteristic of design based on the analytic hierarchy process” is proposed. This method is applied to an under water vehicle. Result indicates that, this method has practical value.
