Development and evaluation of an integrated emergency response facility location model
Abstract: The purpose of this
paper is to propose and compare the performance of the “two” robust mathematical
models, the Robust Integer Facility Location (RIFL) and the Robust Continuous
Facility Location (RCFL) models, to solve the emergency response facility and
transportation problems in terms of the total logistics cost and robustness.
Design/methodology/approach: The emergency response facilities include
distribution warehouses (DWH) where relief goods are stored, commodity
distribution points (CDP), and neighborhood locations. Authors propose two
robust models: the Robust Integer Facility Location (RIFL) model where the
demand of a CDP is covered by a main DWH or a backup CDP; the Robust Continuous
Facility Location (RCFL) model where that of a CDP is covered by multiple DWHs.
The performance of these models is compared with each other and to the Regular
Facility Location (RFL) model where a CDP is covered by one main DWH. The case
studies with multiple scenarios are analyzed.
Findings: The results illustrate that the RFL outperforms others under
normal conditions while the RCFL outperforms others under the emergency
conditions. Overall, the total logistics cost and robustness level of the RCFL
outperforms those of other models while the performance of RFL and RIFL is
mixed between the cost and robustness index.
Originality/value: Two new emergency distribution approaches are modeled,
and evaluated using case studies. In addition to the total logistics cost, the
robustness index is uniquely presented and applied. The proposed models and
robustness concept are hoped to shed light to the future works in the field of
disaster logistics management.
