  abstract	= {The problem of optimal sensor locations in nonparametric
		  identification of viscoelastic materials is considered.
		  Different criteria of the covariance matrix, connected to
		  A- and D-optimal experiment design, are considered and
		  evaluated. The results of the paper can be used to design
		  experiments with improved accuracy of the estimates.}
