Chinese postman problem with priority nodes
Tomaž Kramberger, Gregor Štrubelj, Janez Žerovnik, 2009, original scientific article

Abstract: A generalization of the Chinese Postman Problem is studied in which the delays at a subset of priority nodes are penalized in the cost function. As it is shown that the problem is NP-hard, two tour constructing heuristics are proposed, and their properties are studied. It is proved that one of the heuristics gives optimal solutions on a subset of instances with bounded cost of delays. The implementations of the heuristics are compared on several types of randomly generated instances.

Port hinterland modelling based on port choice
Tomaž Kramberger, Bojan Rupnik, Gregor Štrubelj, Klemen Prah, 2015, original scientific article

Abstract: This paper presents a new approach for hinterland modelling based on the results of port choice modelling. The paper follows the idea that the shippers' port choice is a trade-off between various objective and subjective factors. The presented model tackles the problem by applying the AHP method in order to obtain ports' preference rates based on subjective factors, and combine them with objective factors, which include port operation costs, sailing times, and land transport costs using MILP. The ports' hinterlands are modelled by finding the optimal port of choice for different locations across Europe and merging the identical results. The model can be used in order to produce captive hinterland of ports and can also be exploited in order to analyse how changes in the traffic infrastructure influence the size of hinterlands.
