This article deals with two approximation formulae for estimation of W<sub>q</sub><sup><</sup>, mean waiting-time in a M/E<sub>k</sub>/R queueing system. It is shown how W<sub>q</sub><sup><</sup> for the multiple-channel system with \lambda = \lambda, \mu = \mu is approximately Rth part of W<sub>q</sub><sup>-</sup>, mean waiting-time in a single-channel system with \lambda...</</sup></sup></</sup></sup>
