A container multimodal transportation scheduling approach based on immune
affinity model for emergency relief
ABSTRACT
Various disasters with serious results are reported and happen around our lives. Most of them are unconventional
contingency events. Emergency relief is an important activity dealing with the disasters to
transfer a large number of materials to the destroyed places for casualties and reconstruction for the
country, even the world. Container multimodal transportation will play an important role because of
its superior characteristics. The relations in the process of supply and transportation build up the container
supply chain. It is critical to schedule the multimodal transportation flow of the chain with time
efficiency of higher reliability. In this study, the system of container multimodal transportation emergency
relief is modeled as an affinity network inspired by the immune system. An integer linear programming
model is proposed to build the path selection for container supply chain in the context of
emergency relief. The simulation study shows the promising effects of the model. The study is valuable
for designing the emergency logistics management system with optimal path selection and flow design of
container supply chain in disaster environments.
Models for relief routing: Equity, efficiency and efficacy
ABSTRACT
In humanitarian relief operations, vehicle routing and supply allocation decisions are critically
important. Similar routing and allocation decisions are studied for commercial settings
where efficiency, in terms of minimizing cost, is the primary objective.
Humanitarian relief is complicated by the presence of multiple objectives beyond minimizing
cost. Routing and allocation decisions should result in quick and sufficient distribution
of relief supplies, with a focus on equitable service to all aid recipients. However, quantifying
such goals can be challenging. In this paper, we define and formulate performance
metrics in relief distribution. We focus on efficacy (i.e., the extent to which the goals of
quick and sufficient distribution are met) and equity (i.e., the extent to which all recipients
receive comparable service). We explore how efficiency, efficacy, and equity influence the
structure of vehicle routes and the distribution of resources. We identify trends and routing
principles for humanitarian relief based on the analytical properties of the resulting problems
and a series of computational tests.
