LSDTs: LLM-Augmented Semantic Digital Twins for Adaptive Knowledge-Intensive Infrastructure Planning Open
Digital Twins (DTs) offer powerful tools for managing complex infrastructure systems, but their effectiveness is often limited by challenges in integrating unstructured knowledge. Recent advances in Large Language Models (LLMs) bring new p…
Assessing Response Disparities in California Wildland-Urban-Interface (WUI) Cities Using the Compartmental Model Open
The increasing frequency and severity of wildfires pose significant risks to communities, infrastructure, and the environment, especially in Wildland-Urban Interface (WUI) areas. Effective disaster management requires understanding how the…
Trade-in operations under retail competition: Effects of brand loyalty Open
Trade-in promotions are increasingly recognized as an effective strategy in retail operations to boost sales. Retail firms can restrict their trade-in programs to current consumers through an exclusive trade-in program or accept trade-ins …
Dynamics Analysis and Optimal Control for a Delayed Rumor-Spreading Model Open
In this work, we analyze a delayed rumor-propagation model. First, we analyze the existence and boundedness of the solution of the model. Then, we give the conditions for the existence of the rumor-endemic equilibrium. Regrading the delay …
Dynamics Analysis of a Mathematical Model for New Product Innovation Diffusion Open
In this paper, a mathematical model with time-delay-related parameters and media coverage to describe the diffusion process of new products is proposed, in which the time-delay-related parameters denote the stage in which potential custome…
Pricing Decisions in Closed-Loop Supply Chains with Competitive Fairness-Concerned Collectors Open
Based on the Shapley value fairness concern framework, a fairness concern utility system is established for the closed-loop supply chain (CLSC) with one manufacturer, one retailer, and two competitive collectors. Under the five models (one…
Pricing Decisions in Closed-Loop Supply Chains With Multiple Fairness-Concerned Collectors Open
In the same model, both distributional fairness concern and peer-induced fairness concern are considered, so are the absolute fairness concern and the relative fairness concern. When there are multiple recycling markets, collectors attach …
Pricing Decisions in Closed-Loop Supply Chains with Peer-Induced Fairness Concerns Open
The importance of behavioral factors in the process of decision making is widely recognized in literature and practice. The aim of this paper is to examine the influence of collectors’ multiple fairness concerns on pricing decisions in a c…
To License or Not to License Remanufacturing Business? Open
Many original equipment manufacturers (OEMs) face the choice of whether to license an independent remanufacturer (IR) to remanufacture their used products. In this paper, we develop closed-loop supply chain models with licensed and unlicen…
Optimization of a Traffic Control Scheme for a Post-Disaster Urban Road Network Open
Traffic control of urban road networks during emergency rescues is conducive to rapid rescue in the affected areas. However, excessive control will lead to negative impacts on the normal traffic order. We propose a novel model to optimize …
