When Shortages Lead to Export Restrictions: A Computational Study
Martha L. Sabogal De La Pava, Emily L. Tucker, Yongjia Song
Globalization has enabled companies to leverage cost efficiencies; however, it has increased exposure to disruption risks that threaten supply stability. Among these, export bans h…
Markov Chain-based Policies for Multi-stage Stochastic Integer Linear Programming with an Application to Disaster Relief Logistics
Margarita P. Castro, Merve Bodur, Yongjia Song
We introduce an aggregation framework to address multi-stage stochastic programs with mixed-integer state variables and continuous local variables (MSILPs). Our aggregation framewo…
Multi-stage Stochastic Programming Methods for Adaptive Disaster Relief Logistics Planning
Murwan Siddig, Yongjia Song
We consider a logistics planning problem of prepositioning relief items in preparation for an impending hurricane landfall. This problem is modeled as a multiperiod network flow pr…
A Multi-stage Stochastic Programming Model for Adaptive Biomass Processing Operation under Uncertainty
Berkay Gulcan, Yongjia Song, Sandra D. Eksioglu
Variations of physical and chemical characteristics of biomass reduce equipment utilization and increase operational costs of biomass processing. Biomass processing facilities use…
Rolling Horizon Policies in Multistage Stochastic Programming
Murwan Siddig, Yongjia Song, Amin Khademi
Multistage Stochastic Programming (MSP) is a class of models for sequential decision-making under uncertainty. MSP problems are known for their computational intractability due to…
Optimization Models for Integrated Biorefinery Operations
Berkay Gulcan, Sandra D. Eksioglu, Yongjia Song +2
Variations of physical and chemical characteristics of biomass lead to an uneven flow of biomass in a biorefinery, which reduces equipment utilization and increases operational cos…
