A Stochastic Discrete Optimization Model for Multimodal Freight Transportation Network Design

Since the freight transport mostly incorporates several modes and transshipments, the uncertainty issue becomes more and more important.This uncertainty can be influenced by several factors, which essentially affect the transportation cost.This paper presents a stochastic discrete optimization model for designing multimodal freight transportation network, which includes the decision simply boho classroom of transshipment location and mode choice.Taking different direction from the previous researches, the model takes into account the variation effect of traffic flow, capacity and loading/unloading productivity to the freight cycle time which directly influences the transportation cost.A Monte Carlo simulation is then applied to propagate those variations by following the observed distribution.

A combinatorial optimization model is also incorporated to find the right combination of transportation alternatives, where genetic local search (GLS) My Mom Dad Is Well Trained Funny Cartoon Dog Gift For Dog Lover Personalized Shirt is invoked.Its applicability is then tested to an actual multimodal network, which consists of sea and land transportation modes and several transshipment terminals.
