There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Multi-level spatial models are proposed to approximate large size
logistics network systems. The linkage across different levels of spatial models
is specified through estimating equations to utilize information considered at different
stages. The multi-level models are applied in decision analysis of logistics systems
such as facility location allocation and demand forecasting problems. System
reliability of logistics service is introduced to characterize the uncertainty of
supply chain disruptions. In particular, a sum-of-disjoint-product (SDP) method
is presented to evaluate the system reliability. Real-life examples show the potential
use of the models in characterizing logistics networks, assisting logistics planning
processes and evaluating network designs for dealing with unexpected supply chain
disruption. (Joint work with J.-C. Lu and P. H. Kvam).
