Abstract
A special method for construction of transitive orientations of the undirected graph $G=(X;U)$ is proposed. The method uses an iterative procedure for factorization of graph $G$. Factorization procedure consists in replacing of a B-stable subgraph with a vertex. Transitive orientations are obtained by a polynomial time algorithm which is presented in the paper.
