Embodiment

[0056] There are 4 systems in an unmanned aerial vehicle control system operation performance evaluation, and 4 evaluation indicators are selected at the same time; among them, indicators 1 and 2 are benefit indicators, indicators 3 and 4 are cost indicators; and 3 time periods Table 1 shows the system index information data in each time period.

[0057] Table 1 Information data of each system index in each time period

[0058]

[0059] According to steps 2, 3, and 4, the index weights of each time period are calculated as:

[0060] ω(t 1 )=(0.265380,0.219047,0.168426,0.347148)

[0061] ω(t 2 )=(0.263363,0.206387,0.249882,0.280368)

[0062] ω(t 3 )=(0.325412,0.215782,0.234099,0.224707)

[0063] Calculate each system t according to step 5 k The weighted intuitionistic fuzzy decision matrix for the time period is:

[0064] R ( t 1 ) = ...

Abstract

The invention discloses an unmanned aerial vehicle control system operation performance evaluating method based on an intuitionistic fuzzy entropy weight, which comprises the steps of firstly determining a dynamic intuition fuzzy decision matrix of a system attribute, then determining a weighted intuition fuzzy decision matrix and a weighted dynamic decision matrix of each system tk time period, and finally determining the relative operation performance of each system and sequencing the operation performances of the systems. The system operation performance evaluating method based on the intuitionistic fuzzy entropy weight is advantageous in that a defect of high difficulty in handling a complex uncertain system is overcome; the operation process of the whole system is considered; and the operation performance of the system can be dynamically reflected so that the evaluation is more scientific and more reasonable.

Description

technical field [0001] The invention relates to an evaluation method for the operation performance of a complex system, in particular to an evaluation method for the operation performance of an unmanned aerial vehicle control system based on intuitionistic fuzzy entropy weight. Background technique [0002] The operation performance of the UAV control system refers to the degree to which the operation process performance and system operation result performance of the UAV control system meet the needs and expectations of the system subject and object. The system operation performance evaluation method system consists of constructing the evaluation index system, determining the index weight coefficient, information acquisition method, evaluation method and model, and informatization of the evaluation process. It can be seen that the performance evaluation of system operation is a complex system engineering. However, when actually determining the index value, it is inevitable ...
