in facility location (Pi et al., 2008; Chen et al., 2009) and the other in produc-
tion planning (Wu et al., 2011), and demonstrate how to develop hybrid NP
methods for solving large-scale supply chain optimization.
5.3 Nested Partitions for Facility Location
In this section, we review a detailed implementation of the NP method for
solving the intermodal hub location problem (IHLP), which is rst published
in Pi et al. (2008). IHLP is a hub location problem in the intermodal trans-
portation industry and can be viewed as a special type of discrete facility
location problems.
