Shrinkage simplex-centroid designs for a quadratic mixture model

open access: yesJournal of Industrial Engineering International, 2017
A simplex-centroid design for q mixture components comprises of all possible subsets of the q components, present in equal proportions. The design does not contain full mixture blends except the overall centroid.

Inclusion of the D-optimality in multisine manoeuvre design for aircraft parameter estimation

open access: yes, 2016
This paper is concerned with the designing of simultaneous flight control deflections for aircraft system identification. The elevator, ailerons and rudder are excited with harmonically related multisine signals. The optimal deflections are designed when

Optimal Designs for Direct Effects: The Case of Two Treatments and Five Periods

open access: yesMathematics, 2023
Cross-Over Designs or Repeated Measurements Designs are experimental designs in which treatments (e.g., medicines, fertilizers, diets) are applied to experimental units (usually humans) in different time periods.

Generating Improved Experimental Designs with Spatially and Genetically Correlated Observations Using Mixed Models

open access: yesAgronomy, 2018
The aim of this study was to generate and evaluate the efficiency of improved field experiments while simultaneously accounting for spatial correlations and different levels of genetic relatedness using a mixed models framework for orthogonal and non ...

D-optimal designs for multinomial logistic models [PDF]

open access: yesThe Annals of Statistics, 2020
We consider optimal designs for general multinomial logistic models, which cover baseline-category, cumulative, adjacent-categories, and continuation-ratio logit models, with proportional odds, non-proportional odds, or partial proportional odds assumption.

Algorithms for the minimum spanning tree problem with resource allocation

open access: yesOperations Research Perspectives, 2016
We formulate the minimum spanning tree problem with resource allocation (MSTRA) in two ways, as discrete and continuous optimization problems (d-MSTRA/c-MSTRA), prove these to be NP-hard, and present algorithms to solve these problems to optimality.

New Results Regarding the Construction Method for D‑optimal Chemical Balance Weighing Designs

open access: yesActa Universitatis Lodziensis. Folia Oeconomica, 2020
We study an experiment in which we determine unknown measurements of p objects in n weighing operations according to the model of the chemical balance weighing design. We determine a design which is D‑optimal. For the construction of the D‑optimal design,
