Abstract. Scalar methods of evaluation of upper bound of vector processes are considered using discrete multichannel system with uncertain parameters as an example. The uncertainty of the parameters is such that it turns out to be correct to use the apparatus of the first-order parametric sensitivity functions. As a scalarizing function, such common norms as Euclidean and infinite are used. The advantages and disadvantages of the methods are demonstrated.
Keywords: multichannel discrete system, separate channel, vector process, uncertain parameters, singular decomposition, scalar estimate, process quality
