Notes on the Optimum Chemical Balance Weighing Design

2013
In the paper, the model of the chemical balance weighing design, i.e. model in that the result of experiment we can describe as linear function of unknown measurements of objects with known factors, is presented. Additionally, we assume that the measurement errors are uncorrelated and they have different variances.

Some construction of optimum chemical balance weighing designs

2012
W pracy podano nową metodę konstrukcji optymalnych chemicznych układów wagowych wykorzystujące relacje pomiędzy macierzami incydencji częściowo zrównoważonych układów o blokach niekompletnych z podzielnymi grupami o takich samych schematach partnerstwa a macierzą chemicznego układu wagowego.

Constructions of Optimum Chemical Balance Weighing Designs Based on Balanced Block Designs

2016
The paper is studying the problem of estimation of the individual unknown measurements (weights) of p objects when we have at our disposal n measurement operations (weighings). In this problem we use the linear model called chemical balance weighing design under the restriction on the number times in which each object is measured. A lower bound for the

Optimum Chemical Balance Weighing Design under Certain Condition

2014
The problem of estimation of unknown weights of p objects is considered. The experiment is carried out according to the standard Gauss-Markoff model of the chemical balance weighing design. Existence conditions of the optimum design are given. New construction method of the optimum design based on the set of the incidence matrices of the ternary ...

Balanced Block Designs Leading to the Optimum Chemical Balance Weighing Design with Equal Correlations of Errors

2016
W artykule rozważa się zagadnienie estymacji nieznanych miar poszczególnych obiektów w chemicznym układzie wagowym. Zakłada się, że nie w każdej operacji pomiaru wszystkie przedmioty są uwzględniane oraz że błędy mają jednakowe wariancje i są równo skorelowane.

Note on the optimum chemical balance weighing design for odd number of objects

2016
The problem of the estimation of unknown weights of p objects is considered. The experiment is carry out according to the model of the chemical balance weighing design under the assumption that the measurement errors are correlated. The existence conditions determining the optimum design are presented.
