The global dimension of Noetherian serial rings is studied.
It is proved that if an indecomposable serial ring has infinite global
dimension then it is Artinian and its quiver is a simple cycle.
Using methods of the theory of right serial quivers, we give an upper
estimate on the Loewy length of Artinian rings of finite global
dimension.
Applications to the calculation of the global dimension of tiled
orders of width
