In row designs, n experimental units are arranged in time or along a line. Every experimental unit is allocated to one out of ν treatments. The purpose of this paper is to determine optimal row des...

We investigate the role of orthogonal arrays (OAs) and balanced arrays (BAs) in both full and fractional factorial designs with N runs and m three-level quantitative factors. Firstly, due to the non-existence of the OA(18, 8, 3, 2), we find and const

We focus on circular repeated measurements designs with t = 2 treatments, n experimental units, and p = 2, 3, 4 periods. Our aim is to obtain ϕ-optimal designs, for the estimation of contrasts of d...

This paper attempts to prove the D-optimality of the saturated designs X ∗ and X ∗ ∗ of order 22, already existing in the current literature. The corresponding non-equivalent information matrices M ∗ =(X ∗ ) T X ∗ and M ∗ ∗ =(X ∗

This article provides an upper bound on the number of multi-level columns, denoted by M, in equally replicated optimal designs, minimizing the E ( f N O D ) criterion. These designs are called E ( f N O D ) -optimal. Applying an algorithm and by row

The purpose of this paper is to find and construct optimal designs for estimating the standardized linear and quadratic contrasts in fractional factorials with k factors, each at 3 levels, when the number of runs or assemblies is N. The case N=3m is

Row and column designs are examined and the concept of majorization is applied to find optimal designs,when the observations are either independent or dependent. The dependence follows a first-order autoregression with parameter α. The case of two t

Repeated Measurement Designs, with two treatments, n (experimental) units and p periods are examined. The model examined is with uncorrelated observations following a continuous distribution with constant variance and the parameters of interest are (
