Selected Remarks on Highly D‑efficient Spring Balance Weighing Designs
Acta Universitatis Lodziensis. Folia Oeconomica, 2021 Here, we consider a new construction method of determining highly D-efficient spring balance weighing designs in classes in which a D-optimal design does not exist.

Notes on D‑optimal Spring Balance Weighing Designs
Acta Universitatis Lodziensis. Folia Oeconomica, 2018 Spring balance weighing design is a model of an experiment in which the result can be presented as a linear combination of unknown measurements of objects with factors of this combination equalling zero or one. In this paper, we assume that the variances

A Highly D‑efficient Spring Balance Weighing Design for an Even Number of Objects
Acta Universitatis Lodziensis. Folia Oeconomica, 2019 The problem of determining unknown measurements of objects in the model of spring balance weighing designs is presented. These designs are considered under the assumption that experimental errors are uncorrelated and that they have the same variances ...

On the Optimality of Spring Balance Weighing Designs
The Annals of Statistics, 1983 This paper deals with techniques for finding $\Phi$-optimal designs for weighing $v$ objects in $b$ weighings using a spring balance. The optimality functions considered encompass a large class of functions. Results are applied to find $A$-, $D$- and $E$-optimal designs and the optimal designs obtained are seen to be related to certain types of well ...
