Abstract

This article highlights an application in the area of decision support for planning transports in a railway company utilising constraint logic programming and a flexible design which has been successfully tested on real world data.We discuss the problem formulation for the co-ordination of distinct sub-problems, the allocation of track resources to transports, the allocation of vehicles to transports, and the allocation of personnel to perform the transportation tasks in a railway company and the development of a heterogeneous constraint model which is usable also for other production planning problems.Using constraints as the key technology, we discuss approaches to find interfacing principles to combine several solvers.
