Abstract: The present invention proposes a method for intelligent management of valve production process data, a medium, and an apparatus. Through results of grid classification of sampling points, the method constructs information entropy of grid distribution density levels as well as grid distribution density, which takes into account the circumstance that sampling points may not exist in the classification space, so as to avoid grids where sampling points do not exist from affecting the local density of the sampling points; secondly, based on the core relative distance of the sampling points in a seed grid, the method constructs a coverage density distance, which takes into account the magnitude of the local density of the sampling points in the seed grid as well as differences in the distance from sampling points that have a relatively large local density in the other seed grids.
