Abstract
It is highly necessary to study how to analyze the reliability of simulation data under small sample circumstance when the number of times live operational test is strictly limited. Based on the analysis of existing test ideas and methods, combined with the characteristics of sequence statistics of uniform distribution, a new method of consistency verification is proposed by constructing the variable-scale differential quotient sequence statistic. The research shows that this method is not limited by the sample size, and the credibility of the simulation data can be quickly judged by MATLAB programming.
Highlights
With the constant development and perfection of modern modeling and simulation technology, it has gradually become an important class of methods for operational testing that the combat effectiveness and operational suitability test of weaponry and equipment are carried out on the distributed networked computer system acquiring the complete solution of the entire process by constructing a real-life weaponry and battlefield environment [1]
According to the probability theory and mathematical statistics theory, consistency test can be understood as testing whether two sets of data obey the same distribution
Assuming some index data obtained in the live test are: 8.7515, 8.8324, 8.5529, the corresponding index data obtained in the simulation test are:8.7487, 8.6074, 8.4520, 8.9405, 8.7099, 8.8396, 8.8253, 8.7927, 8.6356, 8.6443, 8.7320, 8.6077, 8.6276, 8.9901, 8.7979, according to the above credibility assessment ideas, simulation data credibility assessment steps under small sample circumstance are: (1) The simulation data were randomly divided into 5 groups, one of which was arbitrarily extracted as 8.7487, 8.8253 and 8.6276, and the two groups of subsamples were sorted from small to large to form sequential sub-sample x(k )
Summary
With the constant development and perfection of modern modeling and simulation technology, it has gradually become an important class of methods for operational testing that the combat effectiveness and operational suitability test of weaponry and equipment are carried out on the distributed networked computer system acquiring the complete solution of the entire process by constructing a real-life weaponry and battlefield environment [1]. Due to the constraints of the test period, environmental conditions and funding guarantee, the times of live operational tests carried out on some large-scale weapon systems is often strictly limited and the resulting data show obvious features of small sample. It is highly necessary evaluating the credibility of operational simulation data under small sample circumstance. This paper will improve the test ideas and methods based on the data consistency research results [2] [3] [4], and analyze the credibility of the simulation data in detail
