Research on Billet Defect Marking Path Decision Method

For the billet defects marking path prob-lem, a random sampling algorithm with weights and an improved Vikor algorithm are used to solve it. The defect weight is introduced into the random sam-pling algorithm to improve the distinguishing ability of the algorithm and obtain a better initial feasi-ble solution. Applying an improved Vikor-G J-entropy weighted integrated decision-making method and the combined weights of the G J-entropy weighted method are calculated by the weighted average. Combining the combined weights with the Vikor evaluation system to evaluate each program. The effectiveness of the random sampling algorithm with weights and the improved Vikor algorithm is verified by simulation and practical application.
