Abstract
Multimodal transportation is being increasingly adopted by a large number of freight companies. Multimodal transportation refers to using combinations of various transportation
modes to move commodities from origin to destination. In this paper, a table is created to store the selected simulation results, which we shall refer to as a Multimodal Leg Outcome (MLO) table. This table is then utilized to find an optimal route in a multimodal network for given origin and destination. The model developed in this paper integrates total travel costs and total travel time of the routes subject to the availability of each mode for each leg, to generate the most preferred routes. Due to this model being multi-objective, where the desire is to minimise
more than one objective function, we construct the MLO table using pareto optimal solutions. In our approach, Monte Carlo simulations (MCS) are used to generate random feasible routes and the results are analysed to extract the pareto optimal solutions (pareto front) offering various routes with respective advantages in terms of duration and/or costs. These pareto optimal solutions are then used to develop a Multimodal Leg Outcome (MLO) table. The
proposed approach is then applied to a simple situation and the results are presented. It is shown that the MLO table obtained can be used not only to find an optimal route in the respective multimodal network, given origin and destination, but also can be utilised after altering the
availability of random vertices and/or modes of transportation in the original network.
