摘要:

均匀设计是部分因子设计的主要方法之一, 已被广泛地应用于工业生产、系统工程、制药及其他自然科学中.各种偏差被用来度量部分因子设计的均匀性, 其关键的问题是寻找一个精确的偏差下界, 因为它可以作为衡量设计均匀性的标准.该文给出了4水平对称U-型设计的对称化L2-偏差的下界, 以及2、3混水平和2、4混水平非对称U-型设计的对称化L2-偏差的下界

关键词: U-型设计, 对称化L2-偏差, 下界

Abstract:

Uniform design is one of the main methods of fractional factorials, which has been widely used in industrial production, systems engineering, pharmacy and other natural sciences. Various discrepancies are used to measure the uniformity of fractional factorials, the key is to find an accurate lower bound of the discrepancy, because it can be used as a benchmark which measures uniformity of design. In this paper, the lower bounds for the symmetric L2-discrepancy on symmetrical U-type designs with four-level and asymmetrical U-type designs with two and three mixed levels and two and four mixed levels are abtained.

Key words: U-type design, Symmetric L2-discrepancy, Lower bound
