Optimizing Household Waste Recycling Centre Network Reorganization in Hampshire
Networks, EarlyView.ABSTRACT Local councils across the UK are facing sustained financial pressures, and Household Waste Recycling Centres (HWRCs) are being increasingly considered for closure to reduce expenditure. In 2024, Hampshire County Council, which operates the largest HWRC network in the UK, proposed closing either five or twelve existing sites.

Near-Optimal Convergent Approach for Composed Influence Maximization Problem in Social Networks
IEEE Access, 2019 Crowd psychology is a critical factor when considering information diffusion, which has been modeled as composed influence. The composed influence is represented as a hyperedge in a graph model.

Resource redeployment as an entry advantage in resource‐poor settings
Strategic Management Journal, EarlyView.Abstract Research Summary Scarcity of productive factors poses a challenge for firms entering underdeveloped regions. We theorize that incumbent firms can overcome scarcity of skilled human capital in local labor markets by redeploying workers from existing units.

Approximating Submodular Functions Everywhere [PDF]
Proceedings of the Twentieth Annual ACM-SIAM Symposium on Discrete Algorithms, 2009 Submodular functions are a key concept in combinatorial optimization. Algorithms that involve submodular functions usually assume that they are given by a (value) oracle. Many interesting problems involving submodular functions can be solved using only polynomially many queries to the oracle, e.g., exact minimization or approximate maximization.

Optimal Selling Mechanisms With Endogenous Seller Outside Offers
International Economic Review, EarlyView.ABSTRACT We examine a two‐stage selling mechanism design problem, where the buyer makes her report and the seller endogenously decides his effort (hidden investment) to generate a possibly better outside offer. The optimal mechanism shows that the seller's effort depends on the reported value of the buyer; a higher value lowers the seller's incentive ...

Assessing second‐price auctions for parcel exchanges in last‐mile logistics
International Transactions in Operational Research, EarlyView.Abstract The rapid growth of e‐commerce has led to multiple carriers operating in the same regions, creating opportunities for collaboration. However, logistics companies typically operate independently, leading to inefficiencies. Horizontal cooperation, where carriers share resources and infrastructure, can improve efficiency and reduce costs.

Naval Research Logistics (NRL), Volume 73, Issue 5, Page 743-763, August 2026.ABSTRACT This paper examines the impacts of Volume‐Based Procurement (VBP) policies on pharmaceutical supply chains, with a focus on the strategic behaviors of manufacturers. VBP aims to reduce costs and stabilize supplies by centralizing procurement through competition based on volumes and prices.
