摘要：Background: Nearly all the segments about material include acquisition, storage, supplying and management have close connections with the maintenance material consumption information. The material consumption rule has a great significance on all the segments about material include acquisition, storage, supplying, management and improve the scientificalness of material support. Materials and Methods: Through making an analysis of the character of material consumption and some factors that affects material consumption, this study applies partial least-squares regression to solve the problem of material consumption prediction when the sample is small. Results: The example indicates that partial least-squares regression is much more accurate than multiple linear regressions. Conclusion: The models provide a theoretical basis for calculating reserves of material scientifically and have the vital important guiding significance.
