Embodiment 1

[0053] The embodiment of the present invention provides a fuzzy comprehensive evaluation method based on a normal cloud model, combining figure 1 look, figure 1 The schematic flow chart of the fuzzy comprehensive assessment based on the normal cloud model provided by the present invention includes steps S1 to S7, wherein:

[0054] In step S1, various operating indicators to be evaluated in the ship system are obtained, wherein the various operating indicators can be indicators such as radar indicators and diesel engine operating indicators that feed back the operating status of the ship;

[0055] In step S2, an evaluation index set is formed according to various operating indexes. In a specific embodiment of the present invention, taking the two-layer fuzzy comprehensive evaluation model as an example, assuming that the first layer has m operating indexes altogether, denoted as U= {u 1 , u 2 , L, u m}, according to the belonging relationship, m operating indicators are div...

Embodiment 2

[0131] An embodiment of the present invention provides a fuzzy comprehensive evaluation device based on a normal cloud model, including a processor and a memory, and a computer program is stored in the memory. When the computer program is executed by the processor, the above-mentioned normal cloud model based fuzzy comprehensive evaluation method.

[0132] The invention discloses a fuzzy comprehensive evaluation method and device based on a normal cloud model.

Abstract

The invention relates to a fuzzy comprehensive evaluation method and device based on a normal cloud model. The method comprises the following steps: acquiring various to-be-evaluated operation indexes in a ship system; forming an evaluation index set according to multiple operation indexes; according to the evaluation index set, constructing a corresponding evaluation grade set, wherein the evaluation grade set is used for representing evaluation result grades of multiple operation indexes in the evaluation index set; constructing a first cloud model of the evaluation index set, and determining a corresponding first cloud model parameter; constructing a second cloud model of the evaluation grade set, and determining a corresponding second cloud model parameter; determining a corresponding cloud similarity according to the first cloud model and the second cloud model; and according to the cloud similarity, the weight set and a preset fuzzy operator, determining a comprehensive evaluation vector so as to carry out result judgment. According to the invention, the cloud model is utilized to carry out classification evaluation on various operation indexes in the ship system, so that the ship combat readiness integrity can be effectively judged.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a fuzzy comprehensive evaluation method and device based on a normal cloud model. Background technique [0002] The essence of combat readiness assessment is to establish the mapping relationship between accurate test quantitative indicators and fuzzy qualitative concepts, which is an uncertainty assessment problem. As an important method in the category of fuzzy mathematics, the fuzzy comprehensive evaluation method quantitatively characterizes the degree of membership and the subordinate relationship between the evaluation object and the qualitative concept through the degree of membership, and can express this uncertainty well through quantitative values. , to obtain more scientific evaluation results. However, there is no unified standard for the membership function of the evaluation index of ship combat readiness, and it needs to be determined by expert experience, which intr...
