| Abstract | Transport sector is the largest energy consuming sector in Thailand. Road haulage, which accounts for more than 80% of the total domestic freight movements, is the least efficient mode in the transport sector (except air transport, which is not considered in this study) as compared to rail and inland water transport regarding energy efficiency. One option to reduce energy consumption is to shift freight to more energy efficient modes or using combination of modes through intermodalism. Such modal shift can also reduce the congestion on road and environmental pollutions. In this paper, optimal percentages of freight share by different modes or combination of modes are determined using multi-objective linear programming model to minimize energy consumption, shipment time and shipment charge. WWW-NIMBUS, a web-based software, is used for the optimizations. The input parameters of the model are determined by extensive data collected from different types of companies (transport operators, freight forwarders and shippers) of Thailand. Adjustment factors for energy and shipment time are also determined for capacity utilization considering load factor and empty haulage. The optimization model is used to obtain a number of alternative Pareto optimal solutions by changing the preferences. The output from the model shows that 24% to 30% reduction of energy consumption is possible by choosing various alternatives. Another benefit obtained from such fuel savings is large reduction of pollutant emissions on the road. The optimization model is also applied to observe the changes in freight share from facility improvements and subsidizing intermodal transport. Result from a case study shows that considerable improvement of rail and water transport share is possible by reduction of freight tariff and transshipment time at rail terminals by facility improvements or providing subsidy at ports. Such optimization model can be very helpful for logistics companies and government organizations and agencies to take effective policy oriented decisions to promote intermodal transport for sustainable environment |
