摘要基于与某些统计信息披露控制方法的相似之处，本文研究了使用边界收紧算法来提高供应和使用表(SUT)平衡中使用的数据质量的好处。事实证明，收紧边界大大提高了最终平衡的SUT的质量，远远超过了现有的技术。最值得注意的是，当在平衡过程之前实施边界收紧时，情况有所改善--表明它可用作其他办法的宝贵开端。当将更准确的更新信息添加到SUTS中时，它还成倍地提高了SUTS的质量。本文的研究结果有力地表明，这种边界收紧算法将改善平衡过程的输出质量，当应用于处理不确定数据的其他过程时，它同样可能有用。
ABSTRACT This paper investigates the benefits of using a boundary tightening algorithm to improve the quality of the data used in supply and use table (SUT) balancing, building on similarities with certain approaches to statistical disclosure control. Boundary tightening was shown to significantly improve the quality of the finally balanced SUTs well beyond that of existing techniques. Most notably, improvements occurred when boundary tightening was applied prior to the balancing process – showing that it can be used as a valuable preliminary to other approaches. It also multiplied the improvement in SUTs quality when more accurate updated information was added to the SUTs. The findings of this paper strongly suggest that this boundary tightening algorithm will improve the quality of the output of the balancing process and it is equally likely to be useful when applied to other processes that handle uncertain data.
