There is an analogue, but one should replace coequalizers by geometric realizations (homotopy colimits over &Delta;<sup>op</sup>).  If $F : I \to M$ is a diagram in a model category, one has

$$\operatorname{hocolim}_I F = \operatorname{hocolim}_{k \in \Delta^{\operatorname{op}}} \coprod_{i_0 \to \cdots \to i_k \in I} F(i_0).$$
