β¦ Synopsis
To every linear extension L of a poset P = (P. < ) we associate a 0, l-vector x =x(L) with xc = 1 if and only if e is preceded by a jump in L or e is the first element in L. Let the setup polyhedron .Y = conv{x(l): L E U(P)} be the convex hull of the incidence vectors of all linear extensions of P. For the case of series-parallel posets we solve the optimization problem over .Y and give a linear description of 9.

In this paper ten-element classes of limit reliability functions for series-parallel and parallel-series systems with identical components are presented. Next, the results are transferred to the systems with non-identical components. These systems are such that at least the number of their series or
In this article, we consider the circular chromatic number Ο c (G) of series-parallel graphs G. It is well known that series-parallel graphs have chromatic number at most 3. Hence, their circular chromatic numbers are at most 3. If a seriesparallel graph G contains a triangle, then both the chromati
