Embodiment 1

[0027] Such as figure 1 As shown, a hierarchical-based gray clustering estimation method of multi-system satellite communication resource utilization rate mainly includes the following steps:

[0028] S1: When estimating the satellite communication resource utilization rate of L systems, first use the analytic hierarchy process to establish a hierarchical index system for the evaluation target, and use an independent multi-level hierarchical structure to establish a satellite communication resource utilization index system;

[0029] S2: Determine the first level of the index system tree diagram, that is, the lowest level index as the cluster index, and distinguish the cluster index into two types, one is a quantitative index, and the other is a ash content index;

[0030] S3: Set a normalized initial value operator according to the sample value range of the quantitative index in the clustering index, and use the initial value operator to normalize the quantitative index in the cluste...

Embodiment 2

[0064] The present invention will be further described in detail below in conjunction with embodiments, but the present invention is not limited to the following embodiments.

[0065] Assuming that the resource utilization rate of three satellite communication systems Sat1, Sat2, and Sat3 needs to be estimated, the specific steps are as follows:

[0066] Step S1: Suppose there are 3 levels in the system resource utilization index system, the top level index is resource utilization, and the second level contains 2 indexes A 1 , A 2 , The third layer is the bottom layer, which contains 5 indicators B 1 ~B 5 , Where B 1 ~B 3 Is A 1 The corresponding lower index, B 4 , B 5 Is A 2 Corresponding to the lower-level indicators, the satellite communication resource utilization index system is obtained.

[0067] Step S2: Put the bottom five indicators B in the indicator system 1 ~B 5 Determined as a clustering index, where B 4 It is a quantitative index, and the other indexes are gray index. Th...

Abstract

The invention discloses a hierarchy-based gray estimation method for a satellite communication resource utilization rate. According to the method, the problems of multi-dimensional, hierarchical and inconsistent contribution of evaluation indexes involved in multi-system satellite communication resource utilization rate estimation can be solved; firstly, a hierarchical index system is constructedby using an analytic hierarchy process, then clustering index samples are classified and whitened by using a whitening weight function and an initial value operator, then a fixed-weight clustering coefficient of each clustering index relative to each grey class is calculated, the comprehensive weight of each clustering index is calculated by using the analytic hierarchy process, and finally, estimation of multiple systems is performed. According to the method, the subjectivity of a traditional analytic hierarchy process and the weight randomness of a grey clustering analysis method are overcome, and the rationality and the true effectiveness of evaluation are effectively improved.

Description

Technical field [0001] The present invention relates to the technical field of satellite communication, in particular to a method for estimating the utilization rate of satellite communication resources. Background technique [0002] Facing the limited resource capabilities of communication satellites, how to efficiently use satellite communication resources to meet diversified business needs has become a key factor affecting the performance of satellite communication networks. When estimating the resource utilization rate of multiple satellite communication systems, people’s focus on satellite communication application services and the angle of attention are different, and satellite communication carriers of different transmission systems have different effects on resource utilization rates, resulting in satellite communication resource utilization. The evaluation indicators of the rate have the characteristics of multiple dimensions, multiple levels, and inconsistent contributi...
