ABSTRACTTo establish an Association of Southeast Asian Nations (ASEAN) Single Shipping Market (ASSM) is an important part of ASEAN governments’ overall plan to achieve an ASEAN Economic Community by 2015. It is expected that a single shipping market will improve the region’s logistics performance and international competitiveness. To achieve this vision, however, the ASEAN countries need to remove any remaining barriers to logistics performance. In this light, the objective of this paper is to identify these barriers and assess their effects on the logistics performance of shipping and logistics firms based in ASEAN countries. Using a questionnaire-based survey, the study revealed several barriers affecting their logistics performance with varying significance among these countries. Unless these barriers from the perspective of the industry are removed, the ability of the shipping and logistics industry to benefit from a liberalized market would be limited. These perceived barriers are examined in detail and strategies to address them are proposed. The ASEAN experience is applicable to similar countries in the process of integrating their international shipping sector as well as contributes to the understanding of the different barriers and how these barriers can affect the logistics performance of shipping and logistics companies. 相似文献

A method to form a homogeneous mixture using low pressure direct injection of liquid phase LPG, pent-roof combustion chamber, flat-top piston and center-located injector layout is presented. To validate the method, the mixture formation processes in the cylinder were investigated using the CFD code. The effect of different injection timing and engine loads on the mixture formation processes were researched. The simulated results showed that, the intake tumble for high load conditions or the inclined intake swirl for part load conditions would break into small-scale vortex (turbulence) near the end of compression stroke, which enhanced the homogeneous mixture formation. The results also showed that if the liquid phase LPG was injected at 60–80°CA ATDC in intake stroke even at different loads, the homogeneous mixture would be formed under any engine load conditions. 相似文献

In the present study a novel modeling approach is presented to solve the combined internal sloshing and sea-keeping problem. The model deals with interesting effects arising due to the coupled interaction between the sloshing in partially filled containers of several geometries and the ship motion. The study is very important for the liquid cargo carrier operating in rough sea or under different environmental conditions. The resulting slosh characteristics that include transient pressure variation, free surface profiles and hydrodynamic pressure over the container walls have been reported in this study. In addition, the effects of coupled ship response and sloshing on ship motion parameters have also been investigated. The equations of motion of fluid, considered inviscid, irrotational, and partially compressible, are expressed in terms of the pressure variable alone. A finite difference-based iterative time-stepping technique is employed to advance the coupled solution in the time domain. Several parameters of interest, including the container parameters, level of liquid, thrusters modeling and some important environmental factors are investigated. 相似文献
