Blocking response surface designs
The design of experiments involving more than one blocking factor and quantitative explanatory variables is discussed, the focus being on two key aspects of blocked response surface designs: optimality and orthogonality. First, conditions for orthogonally blocked experiments are derived. Next, an algorithmic approach to computeD-optimal designs is presented. Finally, the relationships between d...
متن کاملBlocking sets in handcuffed designs
In this paper we determine the spectrum of possible cardinalities of a blocking set in a H(v,3,A) and in a H(v,4,1). Moreover we construct, for each admissible ~9, a H(v,3,1) without blocking sets. Introduction A handcuffed design with parameters v, k, A, or for short an H(v,k,A), consists of a set of ordered k-subsets of a v-set, called handcuffed blocks. In a block (a., a z ' ... ,a!:) each e...
متن کاملAn Algorithmic Construction of Four-Level Response Surface Designs
Response surface methodology is widely used for developing, improving and optimizing processes in various fields. In this paper we present a method for constructing four-level design matrices in order to explore and optimize response surfaces where the predictor variables are each at four equally spaced levels, by utilizing a genetic algorithm. The produced designs achieve both properties of ne...
متن کاملG-designs without blocking sets, Note
For an undirected graph G and a natural number n, a G-design of order n is an edge partition of the complete graph Kn with n vertices into subgraphs G1, G2, . . . , each isomorphic to G. A set T ⊂ V (Kn) is called a blocking set if it meets the vertex set V (Gi) of each Gi in the decomposition, but contains none of them. In a previous paper [J. Combin. Designs 4 (1996), 135–142] the first and t...
