Embodiment Construction

[0067] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0068] The method for evaluating the reliability of the command and control system provided in this embodiment includes the following steps:

[0069] The first step is to collect the cumulative running time and cumulative number of faults of all units in the command and control system according to the operation of the command and control system.

[0070] The second step is to determine the type of command and control system, and calculate the cumulative running time and cumulative fault number of the system

[0071] Calcu...

Abstract

The invention discloses a method for evaluating the reliability of a command and control system. The method comprises the following steps of: acquiring the accumulated operation time and the accumulated failure number of various units in the command and control system; determining the type of the command and control system, and calculating the accumulated operation time and the accumulated failure number of the command and control system according to the type of the system and the accumulated operation time and the accumulated failure number of various units; calculating a lower confidence limit of the mean time between failures MTBF of the command and control system according to the accumulated operation time and the accumulated failure number of the command and control system; and calculating a reliability evaluation result of the command and control system according to the accumulated operation time and the accumulated failure number of the command and control system and the lower confidence limit of the mean time between failures MTBF of the command and control system. Compared with the before evaluation method, the technical scheme provided in the invention has the advantages that: the evaluation time is shortened; the evaluation efficiency is increased; and furthermore, by means of the reliability evaluation result, objective basis is provided for determining whether the reliability of the command and control system satisfies requirements or not.

Description

technical field [0001] The invention relates to a systematic reliability evaluation method. More specifically, it relates to a reliability assessment method for command and control systems. Background technique [0002] With the development and growth of the military power of various countries in the world, weapons and equipment are more and more valued and loved by all countries. In order to strengthen the national defense force, resist external provocations and protect national security, improving the reliability of weapon systems is an important content of air defense weapon equipment research. The command and control system is the brain and core of the weapon system, and the reliability of the command and control system determines the reliability of the weapon system. In modern and future high-tech warfare, the battlefield environment is extremely complex, there are many uncertain factors, and the reliability and survivability of the command and control system are seri...
