On equivalence of fractional factorial designs based on singular value decomposition
: The singular value decomposition of a real matrix always exists and is essentially unique. Based on the singular value decomposition of the design matrices of two general 2-level fractional factorial designs, new necessary and sufficient conditions for

Two-level Minimum Aberration Fractional Factorial Designs in the Presence of Dispersion Factors
在實驗初期通常實驗資料的變因有很多,因此2-變級複因子設計被廣泛用於估計實驗中重要的位置效應。而同質變方是變方分析中最基本的假設,在此假設成立下,最適2n-p部分複因子設計的研究已相當完善。但是當實驗的反應變數之變異程度,會因某些因子在不同變級而有顯著的差異時,我們稱這些因子為分散因子。然而在分散效應存在下,如何決定最適設計是一個在文獻上少見的研究議題,若能找出合適的設計,不但可以減低實驗的成本,也可以提高實驗的效率,因此這是個值得深入探討的研究議題。 本研究是針對在已知具有分散因子存在 ...

Indicator function and complex coding for mixed fractional factorial designs
In a general fractional factorial design, the n levels of a factor are coded by the nth roots of the unity. This device allows a full generalization to mixed-level designs of the theory of the polynomial indicator function which has already been ...

An adjustment algorithm for the construction of optimal run orders. [PDF]
Using a systematic run order can be the proper way to conduct an experiment when a temporal trend is present. The construction of run orders that are optimally balanced for time trend effects is based on the maximization of the information on the ...

On Construction of Odd-fractional Factorial Designs
Fractional designs involve selection from a given set of experimental treatments as subset of treatments to make-up a specified design measure that has such statistical properties as balance, high relative efficiency, D-optimality etc.
