ppt on platform assignment of train with er diagram with data flow diagram
Abstract
We consider a station in which several trains might stop at the same platform at the same time. The trains might enter and leave the station to both sides, but the arrival and departure times and directions are fixed according to a given time table. The problem is to assign platforms to the trains such that they can enter and leave the station in time without being blocked by any other train. We consider some variation of the problem on linear time tables as well as on cyclic time tables and show how to solve them as a graph coloring problem on special graph classes. One of these classes are the so called circular arc containment graphs for which we give an O(n log n) coloring algorithm.
