Optimizing sales areas of combined transport chains

Michalk P.

LogForum

2013

Vol. 9, no. 4

247--253

Background: Combined transport chains (such as intermodal transport), have certain advantages. The main advantage from customer points of view is the possibility to bundle freight and thereby decrease transport costs. On the other hand, a combined transport chain can cause longer transport times, due to the necessary transshipment processes. Methods: The area around a terminal, in which a combined service has favourable properties to a customer in comparison to a direct transport, can be understood as a sales-area, in which a combined transport product is marketable. The aim of this paper was to find a method to determine the best shape and size of this area. Results and conclusions: The paper at hand lined out a method in order to calculate such a sales area and determine which geographical points around a terminal have an advantage in comparison to a direct transport service.

Wstęp: Łańcuch transportu kombinowanego (takiego jak na przykład transport intermodalny) ma szereg zalet. Z punktu widzenia klienta najważniejszą zaletą jest możliwość łączenia różnych przewozów i w efekcie obniżenie kosztów transportu. Z drugiej strony transport kombinowany wymaga często dłuższego czasu realizacji, ze względu na potrzebne czasy przeładunków. Metody: obszar położony wokół terminala, na którym realizacja dostaw poprzez transport kombinowany jest korzystniejsza od transportu bezpośredniego, jest określany jako obszar sprzedaży. Celem tej pracy było znalezienie metody wyznaczania takiego obszaru. Wyniki i wnioski: Przedstawiono metody obliczania obszaru sprzedaży oraz wyznaczania punktów geograficznych ograniczających ten obszar.

Improving baltic sea services : a quantitative planning approach

Reduction of inventories and optimum delivery of input goods are important parameters for efficient production processes. Therefore transport processes are a vital part of industrial production, and their features are important determining factors for production planning. Especially in the Baltic Sea region, short sea roro shipping connections are an important part of transport chains but also constitute a bottleneck through their restricted schedules. The attractivity of a short-sea roro shipping connection is determined through several factors. Among these are shipping prices, transport time, frequency but also factors that cannot be influenced by the ships operator, such as obligatory driver breaks for truck drivers, which use the shipping service, the geographical position of ports and the geographical position of logistics hotspots which determine the main-transport flows. A roro shipping service that is part of an optimal connection between two logistics hotspots would have a clear advantage on the market. The paper shall present a model that allows for the analysis of complete intermodal RoRo-shipping chains in regard to their attractivity for their end-customers. The model cumulates different features of a transport chain into one indicator. Thereby allowing the optimization of RoRo shipping connection towards customer needs.
