The aim of the present paper is to explain the Mediterranean Transhipment Rule by a mathematical model showing the relationship between the diversion distance and the transhipment volumes, as well as the relationship to the total container traffic volume. Thus, the formula was applied to the figures achieved in 1994, 1995 and 1996. To conform with 1994, 1995 and 1996 data the formula was slightly altered so as to forecast transhipment volumes in the Mediterranean ports. By applying the formula to the figures achieved by some Mediterranean ports, the estimations were done which describe reliably enough that the transhipment volumes depend on the diversion distance and the total traffic throughput. In short, the volume of cargo transhipped in a single port is an inverse linear function of the distance of the port from the main-line vessels' route transiting the Mediterranean, and a linear function of the port container traffic volumes. 相似文献

Active suspension is commonly considered under the framework of vertical vehicle dynamics control aimed at improvements in ride comfort. This paper uses a collocation-type control variable optimisation tool to investigate to which extent the fully active suspension (FAS) application can be broaden to the task of vehicle handling/cornering control. The optimisation approach is firstly applied to solely FAS actuator configurations and three types of double lane-change manoeuvres. The obtained optimisation results are used to gain insights into different control mechanisms that are used by FAS to improve the handling performance in terms of path following error reduction. For the same manoeuvres the FAS performance is compared with the performance of different active steering and active differential actuators. The optimisation study is finally extended to combined FAS and active front- and/or rear-steering configurations to investigate if they can use their complementary control authorities (over the vertical and lateral vehicle dynamics, respectively) to further improve the handling performance. 相似文献
