Designing Hierarchical Hub-and-Spoke Drone-Based Networks for Delivering Time-Sensitive Healthcare Items
Sayed Hamid Hosseini Dolatabadi, Tanveer Hossain Bhuiyan, Bo Zeng +2
The paper proposes a hierarchical hub-and-spoke drone network for fast delivery of time‑sensitive medical items, using a mixed‑integer programming model and specialized solution me…
New Outer Approximation Algorithms for Nonsmooth Convex MINLP Problems
Zhou Wei, He-Yi Liu, Bo Zeng
This paper presents a novel outer approximation algorithm for nonsmooth mixed-integer nonlinear programming (MINLP) problems. The method proceeds by fixing the integer variables an…
Leveraging Electric School Buses for Disaster Recovery: Optimizing Routing and Energy Scheduling via Branch-and-Price
Sayed Hamid Hosseini Dolatabadi, Yuchen Dong, Tanveer Hossain Bhuiyan +3
Natural disasters threaten the resilience of power systems, causing widespread power outages that disrupt critical loads (e.g., hospitals) and endanger public safety. Compared to t…
On the Existence of Lagrange Multipliers in Distribution Network Reconfiguration Problems
Rong-Peng Liu, Yue Song, Xiaozhe Wang +1
Distribution network reconfiguration (DNR) is an effective approach for optimizing distribution network operation. However, the DNR problem is computationally challenging due to th…
