ON D-OPTIMAL CHEMICAL BALANCE WEIGHING DESIGNS [PDF]
The paper deals with the problem of determining the chemical balance weighing designs satisfying the criterion of D-optimality under assumption that the measurement errors are equal correlated and they have the same variances.

CONSTRUCTION METHOD OF A-OPTIMAL CHEMICAL BALANCE WEIGHING DESIGNS [PDF]
Here, we study the design in that we determine unknown measurements of p objects by used of n measurement operations. For that reason we consider the chemical balance weighing design under assumption that the measurement errors are uncorrelated and they ...

On the optimality of chemical balance weighing designs
Optimality of chemical balance weighing designs is considered in this paper. The authors have used a ternary design matrix \(X_ d\in C(N,n)\) for \(N\geq n\) with entries -1,0,1. The authors have chosen the optimality criteria of type I as defined by \textit{C.-S. Cheng} in Ann. Stat. 8, 436- 446 (1980; Zbl 0425.62055).

Some Construction Methods of A-Optimum Chemical Balance Weighing Designs
Some new construction methods of the optimum chemical balance weighing designs and pairwise efficiency and variance balanced designs are proposed, which are based on the incidence matrices of the known symmetric balanced incomplete block designs. Also the conditions under which the constructed chemical balance weighing designs become A-optimal are also

A note on the estimation of total weight in chemical balance weighing designs
This paper studies the problem of estimation of the total weight of objects using a chemical balance weighing design under the restriction |L−R| ≤a, whereL andR represent the number of objects placed on the left and right pans, respectively. A lower bound for the variance of the estimated total weight is given and a necessary and sufficient condition ...

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

A Regular D‑optimal Weighing Design with Negative Correlations of Errors
The issues concerning optimal estimation of unknown parameters in the model of chemical balance weighing designs with negative correlated errors are considered. The necessary and sufficient conditions determining the regular D‑optimal design and some new
