Abstract: The paper presents the results of research concerning on the estimation of individual weights of objects in spring balance weighing design. We consider D-optimal weighing design under assumption that the errors are uncorrelated and they have different variances. The upper bound of the determinant of the information matrix of estimators is given and the conditions for this upper bound to be attained are proved. Some examples of the regular D-optimal spring balance weighing designs are demonstrated.
