Abstract :The problems linked with an A-optimal spring balance weighing design with correlated errors are discussed. The topic is focus on the deter- mining the lowest bound of the trace of inverse information matrix in a special class of design matrices. The constructing method of the optimal design, based on the incidence matrices of balanced incomplete block designs, is presented.Keywords : A-optimal design, balanced incomplete block design, spring balance weighing design
