To account for the non-equilibrium character of quark-gluon plasma formation in relativistic heavy-ion collisions, it is proposed to use the product of energy density ε and interaction time τ<sub>int</sub> (rather than ε) as the critical quantity for plasma formation. In a geometrical model, τ is approximated by the transit time, and ε by the maximum energy density calculated in the center-of-mass frame. For central collisions, an analytical expression for ε·τ is given. As an example, the systems <sup>16</sup>O + <sup>16</sup>O and <sup>208</sup>Pb + <sup>208</sup>Pb are investigated as functions of c.m. energy, and their respective suitability for plasma formation is discussed.
