Warship reliability quantitative requirement demonstration method

Abstract

The invention discloses a warship reliability quantitative requirement demonstration method. The method comprises the following steps of: 1, determining a warship reliability top layer parameter index; 2, decomposing the warship reliability top layer parameter index; 3, determining a warship reliability parameter limit value; 4, balancing the warship reliability parameter index and expense; and 5, analyzing the technical and economic practicability of the warship reliability parameter index. By adopting the method, a warship reliability quantitative requirement demonstration method which is consistent with the condition of China and has high operability is provided for the determination of a warship reliability parameter, warship reliability quantitative requirement demonstration work is guided, and reliability level of a warship is raised.

Description

1. Technical Field [0001] The invention provides a method for demonstrating quantitative requirements for ship reliability, which belongs to the technical field of reliability engineering. 2. Background technology [0002] Ship demonstration is a systematic analysis and design process based on the level of science, technology and economic development, with the quality and scale of existing ships as the background, and scientific theories and methods. Ship demonstration is the primary link in the process of ship development and the foundation of ship development work. Practice has proved that where the argumentation is sufficient, the project is determined objectively, the target is clear, the requirements and indicators are more reasonable, and the ship developed has a high success rate and short cycle; conversely, projects with insufficient argumentation, or late ship development If it fails to come out, or cannot be used effectively after it is developed, it causes a huge wast...

AI Technical Summary

Problems solved by technology

But generally speaking, there are still certain defects, such as incomplete parameters, unclear concepts of the proposed parameters, insufficient feasibility of the parameters, etc. In addition, the lack of demonstration techniques and means also greatly restricts the reliability engineering in ship development. development

Due to the relatively late development of reliability engineering technology compared with the traditional weapon engineering technology, coupled with the traditional concept of emphasizing combat performance and not paying attention to the existence of reliability performance (which still exists to varying degrees), there are irregularities and irregularities in reliability demonstration. Unreasonable and poorly scientific means of argumentation
