Multi-scale Spatial Modeling for Logistics System Reliability Evaluations

چکیده
This article proposes a multi-scale model suitable for describing patterns of store locations in a large-size supply-chain system. This model uses continuum approximation to simplify the detailed logistics network and supports various levels of decisions, such as robust logistics network designs and service area allocations for distribution centers. Several definitions and formulas are developed for evaluating reliability of logistics service and performance degradation of logistics networks when a distribution center does not perform to its full capability. Examples with store locations data taken from a large-size retail-chain illustrate impact of different network designs to system reliability and service degradation performance.
