Optimizing Sustainable Networks for Biomass Pellet Processing Depots Under Supply Uncertainty
This study develops a two-stage stochastic mixed-integer programming model to manage multi-purpose pellet processing depots under feedstock supply uncertainty. The model aims to minimize costs and emissions in the supply chain network by considering three Biomass Processing and Densification Depot (BPDD) technologies: conventional pellet processing, high moisture pellet processing, and ammonia fiber expansion. A hybrid decomposition algorithm, combining Sample Average Approximation with an enhanced Progressive Hedging (PH) algorithm, was used to solve this problem, with Mississippi and Alabama as testing grounds. The results of the analysis reveal promising insights that could lead to recommendations to help decision makers achieve a more cost-effective environmentally-friendly supply chain network.
Md Abdul Quddus is an assistant professor in the Department of Textile Engineering, Chemistry and Science at NC State University. He received his Ph.D. in industrial & systems engineering from Mississippi State University in Starkville, Mississippi. He also has over five years of experience at FedEx Express as a Senior Operations Research Advisor, where he worked on various logistics research projects. His research focuses on supply chain and logistics, big data analytics, stochastic programming, geospatial analytics for optimization. Additionally, his work includes the application of AI, machine learning, cloud computing and HPC, and operations research techniques to solve large scale supply chain network and risk management problems. He received multiple Bravo Zulu and leadership excellence awards from FedEx. He also received the Best Paper Award at INFORMS ENRE 2017.
