ItemHyperconnected Logistic Service Networks: Bidding-Based Design Framework(Georgia Institute of Technology, 2023-06) Kwon, Simon ; Montreuil, Benoit ; Dahan, Mathieu ; Klibi, WalidIn hyperconnected urban logistics, all components and stakeholders are connected on multiple layers through standardized interfaces and open networks to achieve seamless responsiveness, efficiency, resilience, and sustainability. Key for high performance is achieving coordination and cooperation of urban stakeholders. In this Paper, we introduce the design of hyperconnected logistic service networks where associated logistic activities to move flows within an urban city are outsourced to third-party logistic service providers (3PL) via a bidding process to create service networks that are highly responsive and flexible at robustly responding to customer demand. We propose a framework for designing such networks that leverages a reverse combinatorial auction mechanism in which a logistic orchestrator serves as the auctioneer, putting out the logistic activities for auction and a set of participating service providers serve as bidders. We describe the design components of hyperconnected service networks and positions them into a comprehensive 3-stage design-making framework. Finally, we identify promising future research avenues for each stage in the proposed framework.

ItemHyperconnected Urban Synchromodality: Synergies between Freight and People Mobility(Georgia Institute of Technology, 2023-06) Labarthe, Olivier ; Klibi, Walid ; Montreuil, Benoit ; Deschamps, Jean-ChristopheThis Paper investigates the opportunity to exploit an on-demand freight transshipment service in urban areas. This contribution attempts at first to focus on the feasibility to connect people and freight mobility with a joint usage of transportation options. It builds on the hyperconnectivity principles enabled by the Physical Internet (PI) manifesto for city logistics. To this end, this Paper proposes an effective solution approach for optimizing multimodal on-demand transshipment. The approach considers multiple mobility options such as on-demand delivery services, cargo bikes, tramways, and buses to transship goods from an urban logistic hub to another. The hyperconnected synchromodal mobility solution is proposed as an alternative option to classical pickup and deliverybased transportation. The proposal is first characterized in link with the interconnectivity needs and then its operability is modeled as a new transportation approach. The proposed solution aims to increase the sustainability of cities by reducing congestion levels, the impact of logistics moves, as well as carbon emissions in urban areas. An illustrative case is provided to demonstrate how the novel hyperconnected synchromodal transportation system could operate, and to provide an evaluation of the economic and sustainability benefits of such system in an urban context.

ItemHyperconnected Urban Parcel Delivery Network Design with Tight Delivery Service Requirements(Georgia Institute of Technology, 2023-06) Kwon, Simon ; Leveque, Johan ; Klibi, Walid ; Stauffer, Gautier ; Montreuil, BenoitThe advent and growth E-Commerce has led to not only a huge increase in demand for rapid and guaranteed transport/delivery services, but also in the numbers of vehicles entering and leaving urban cities to deliver goods and services, clogging the roads and polluting the air. Seeking efficient usage of resources is inarguable. Motivated by these challenges, this Paper studies the design of hyperconnected parcel network design in line with the Physical Internet initiatives, modelling it as a coalition-formation game. The objective is to design a cooperative parcel delivery network among multiple delivery actors such that the actors within the same coalition can share resources. We develop a case study of La Poste to understand the impact of coalitional decisions and cost-sharing methods on the global and individual network design cost.

ItemDynamic resource deployment in hyperconnected parcel logistic hub networks(Georgia Institute of Technology, 2023-06) Xu, Yujia ; Klibi, Walid ; Montreuil, BenoitWith the development of e-commerce, one of the major challenges for many parcel logistics companies has revealed to be designing reliable and flexible scheduling and deployment approaches and algorithms to meet uncertainties of parcel arrivals and resource availability in logistic hubs. In this Paper, we want to present models to spatiotemporally adjust the available resource, like workforce and robots, across hyperconnected logistic hub networks using a rolling horizon approach. In most traditional parcel logistic hubs, workers are hired to enable the sorting, consolidation, transshipment, and crossdocking of parcels, and most resource scheduling is periodic (e.g., daily) and limited to single facility, thus the number of required resources in each hub is constrained to meet the peak demand with high variance. We here propose dynamic resource scheduling and deployment mechanisms, that are fed with updated data with sensors and dynamically updated parcel arrival predictions at hubs.

ItemModularization of Delivery and Transportation(Georgia Institute of Technology, 2021-06) Kim, Nayeon ; Montreuil, Benoit ; Klibi, WalidTraditional static and optimization based transportation planning and operation system has limitations on supporting highly dynamic, hyperconnected, multi-player logistics system in Physical Internet. Modularizing delivery and transportation can enable flexible transportation operations to adapt to such highly dynamic environment with potentially reduced planning effort. The modularization schemes are categorized into regional, hierarchical, and functional modularization. Regional modularization replaces a long route with many shorter routes, or modules, interconnected via PI hubs. Hierarchical modularization implements a multi-tier transportation system where each tier becomes a module connected via PI hubs. Functional modularization is to ensure each route serves a single functionality, each of which requires different resources. All three modularizations can increase flexibility of planning and operation while increasing the consolidation level and efficiency. Experimental results applying hierarchical and functional modularization for last mile delivery shows up to 27% of operational cost savings.
