WE01.1 Optimization of an Intermodal Terminal Using Constraint Logic Programming Knut Alicke, Dieter Arnold --- Univ. Karlsruhe, Hertzstr. 16, Karlsruhe, 76187 , Germany (knut.alicke@mach.uni-karlsruhe.de)

One of the most challenging optimization problems of an intermodel terminal is finding an optimal container-sequence for the train-to-train-transshipment. We present a new approach based on constraint logic programming to solve this problem. We develop a framework to model the containter-terminal as a constraint satisfaction problem.

WE01.2 Scheduling Container Transfers at Multimodal Terminals P. Preston, Erhan Kozan --- Queensland Univ. of Tech., Sch. of Math. Sci., GPO Box 2434, Brisbane, Queensland, 4001 , Australia (p.preston@fsc.qut.edu.au)

Optimising container transfer schedule at the multimodal terminals is known to be NP-Hard which implies that the best solution becomes computational infeasible as problem sizes increase. Efficient heuristic techniques are used to reduce container handling/transfer times and ships; time in port by speeding up handling operations.

WE01.3 Optimizing Intermodal Operations Over the Rail (Linehaul) Segment of Truck-Rail Intermodal Transportation Alexandra M. Newman, Candace A. Yano --- Univ. of CA, 2773 Park St., Berkeley, CA 94702 , (newman@ieor.berkeley.edu)

Althrough rail intermodal transportation has been gaining popularity in recent years, a significant number of shippers complain about lengthy transit times. We present a formulation for minimizing rail (linehaul) operations while ensuring timeliness of deliveries and briefly discuss our solution procedure. We illustrate our model with numerical results.
