Embodiment Construction
[0039]The present invention provides a method of determining a gas pipeline network leakage based on improving evidence fusion algorithm, and its basic idea is that there is a weak decision-making evidence in the fusion process of evidence that the inventive decision-making evidence is respectively The meta-weighted process, retains the decision status of the maximum trust Jiao Yuan, attenuating the impact of other Jiao Yuan, and the respective Jiao Yuan of weak decision-making evidence is more accurate due to the limit of evidence distortion due to the limitations of Jiao Yuan weight, and is more accurate, Reliable fusion results.
[0040]The present invention will be described in detail below with reference to the accompanying drawings.
[0041]Definition: θ = {θ1, Θ2, ..., θN} To identify the framework, the elements are mutually exclusive and poor, the number of elements is N, θi(1
