TAILIEUCHUNG - Power unit – cargo space link in transport
This paper deals with transportation technology regarding links between power unit and cargo space. These links can be divided into two groups: rigid and flexible. Rigid link, established between power unit and cargo space, is dominant in maritime and road transport (sea ships and trucks), and occasionally in transport on inland waterways (self – propelled barges). Flexible link is used in the railroad transport (systems with trailers and semi trailers), and in inland waterway transport (push – towing and pulling systems, and combinations of the systems). | Yugoslav Journal of Operations Research 15 (2005), Number 1, 49-52 POWER UNIT – CARGO SPACE LINK IN TRANSPORT Zoran RADMILOVIĆ Faculty of Transport and Traffic Engineering, University of Belgrade Branislav DRAGOVIĆ, Vladislav MARAŠ Maritime Faculty, University of Montenegro, Kotor branod@ Presented at XXX Yugoslav Simposium on Operations Research Received: January 2004 / Accepted: January 2005 Abstract: This paper deals with transportation technology regarding links between power unit and cargo space. These links can be divided into two groups: rigid and flexible. Rigid link, established between power unit and cargo space, is dominant in maritime and road transport (sea ships and trucks), and occasionally in transport on inland waterways (self – propelled barges). Flexible link is used in the railroad transport (systems with trailers and semi trailers), and in inland waterway transport (push – towing and pulling systems, and combinations of the systems). The main goal of this research is determination of possible link types and organization of the means of transportation. Keywords: Means of transportation operations, power unit – cargo space link in transport. 1. INTRODUCTION Rigid link power unit has less exploitation time, since it has to wait along with ship cargo space at loading and unloading points, depending on technology used, transportation process geography, and other operations (customs controls, change in transport conditions, etc.). In the use of flexible link between power unit and cargo space, possibilities for higher exploitation time of power unit exist. This is true for time periods during the cargo space operations only. For example, the motorboat and locomotive do not have to wait on tow or railcar units for cargo loading and unloading. The power unit – cargo space link can be considered as queuing systems with bulk arrivals, single service and unlimited queue. 50 Z. Radmilović, B. Dragović, V. Maraš / Power Unit – Cargo Space Link
