Problems solved by technology

[0003] Equipment combat test is a test mode under the new system. At present, there are not many studies on the construction and optimization technology of test identification indicators, but the research results on the optimization and screening methods of indicators in other fields are fruitful.
At present, the optimization methods of the index system can be mainly divided into: first, statistical analysis methods, such as principal component analysis, factor analysis, correlation coefficient method,

Embodiment Construction

[0064] Such as figure 1 As shown, a method for constructing an equipment combat test appraisal index system is characterized in that the steps are as follows:

[0065] 1), construct the decision-making information of the combat test index system, definition 1 Let U be the object set, and R be the equivalence relationship on U;

[0066] (1) (U, R) is called an approximate space, and the equivalence class generated by (U, R) is U / R={[x i ] R |x i ∈ U}, where [x i ] R ={x j |(x i ,x j )∈R}

[0067] (2) For any X∈U, remember,

[0068] say R (X) is the lower approximation of X, is an upper approximation of X.

[0069] (3) If X is called a definable set, otherwise X is called a rough set.

[0070] Knowledge can be represented by information system, and the definition of information system is given below.

[0071] Define 2S=(U,A,V,f) as an information system: U={x 1 ,x 2 ,...,x n} is a non-empty finite set of objects, also called domain of discourse, A={a 1 ,a ...

Abstract

The invention relates to the technical field of equipment test identification. The invention discloses a method for constructing an equipment combat test identification index system. The method is anequipment combat test identification index optimization method based on a rough set and a genetic algorithm and comprises the steps that (1) a basic framework of an equipment combat test index systemis constructed; (2) a decision information table is constructed, the concept of the decision information system is derived from a rough set method, and definition is given to the rough set and the decision information system; (3) the attribute reduction method based on the genetic algorithm comprises the following steps: a) chromosome coding, b) fitness function, c) roulette strategy selection operation, d) crossover operation,..; and (4) a simplified index set is obtained to obtain an attribute reduction set of the equipment decision information system. Through the rough set and the genetic algorithm method, various uncertain information can be well processed, qualitative and quantitative information is analyzed and mined, attributes of the information are reduced, and a simplified indexset is obtained; intelligent evaluation is achieved, and the method is simple, visual and good in effect.

Description

technical field [0001] The invention relates to the technical field of equipment test appraisal, in particular to a method for constructing an equipment combat test appraisal index system. Background technique [0002] Constructing a scientific and reasonable test appraisal index system is the basis for carrying out equipment combat tests, and directly determines the rationality of the test content and test appraisal conclusions. At present, the construction methods of the equipment combat test appraisal index system mainly include the mission task decomposition method, the key combat problem tree decomposition method, and the capability requirement analysis method, etc. The existing index system construction methods can form a relatively comprehensive index system framework that better reflects the characteristics of equipment. However, with the increasing size of the equipment system and the complexity of the combat process, the number of indicators is also increasing. If...
