An activity-based freight mode choice microsimulation model
نویسندگان
چکیده
This study embarked upon the development of a nationwide freight activity microsimulation as an acceptable analysis tool for policy assessments. Mode choice component of a large-scale behavioral microsimulation framework, named Freight Activity Microsimulation Estimator (FAME) was developed and validated in this study. The results of a nationwide establishment survey, discussed in earlier studies, are used to develop the mode choice model for the entire US. Despite many previous freight mode choice models, the proposed model works at the disaggregate level of firm-to-firm. A new concept for firm-types is implemented in FAME to keep the computational burden at a reasonable level and to diminish the need for highly disaggregated data. A total of 45 206 firm-types were synthesized in the US, among which more than 14?8 billion tonnes of domestic shipments were simulated. Total tonnage, value, and tonne-mile of commodities for each mode were obtained as the final output, which showed a satisfactory match with public freight data in the US.

متن کاملContinuous Review Inventory Model with Dynamic Choice of Two Freight Modes with Fixed Costs
We analyze a continuous review stochastic inventory model in which orders placed with a make-to-order manufacturer can be shipped via two alternative freight modes differing in lead-time and costs. The costs of placing an order and using each freight mode exhibit economies of scale. We derive an optimal policy for utilizing the two freight modes for shipping each order. This freight mode decisi...

Currently, road transportation is the main mode of freight transit in Iran and about 90% of freight transit is done through this mode of transportation which is not in line with the transportation policies that based on them 70% of the freight transit should be done through road transportation and 30% of the freight transit should be done through rail transportation. However, Iran's railway net...
