要約
The paper introduces a sampling model for grid material inspection using an improved Analytic Hierarchy Process (AHP). It aims to enhance detection accuracy by selecting equipment based on comprehensive performance scores. The method utilizes historical data from the Enterprise Control Platform (ECP) to determine inspection levels and optimize material selection. By prioritizing quality scores, the model improves testing efficiency compared to random sampling methods.
統計
The weight distribution of performance indicators reveals that insulation structural performance accounts for 43.6%, electrical performance accounts for 32.1%, and sheath structural performance accounts for 24.3%.
The judgment matrix compares each element of the lower level with the elements of the upper level based on judgment criteria to determine values.
The test results are divided into four levels: excellent, good, qualified, and basic qualified, with corresponding scores assigned.
Weighted quality scores are calculated by combining indicator weight values using a specific formula.
A comparison with Artificial Neural Network (ANN) and Random Forest (RF) models shows significant performance advantages in predicting power cable quality levels.
