To address this challenge, this paper proposes a new variant of the multi-period inventory routing problem, which focuses on coordinating discrete, time-varying demands for auto parts on the assembly line with predetermined packages at suppliers over a finite short-term time horizon (e.g., on an hourly basis). The objective is to minimize the total transportation and inventory cost by making aperiodic decisions on collection quantities and traveling routes simultaneously for an inbound warehouse near the assembly plant. An integer programming (IP) formulation with time-indexed variables is tailored for the problem to analyze the feasibility conditions. Then, a reformulation is designed to make the problem more tractable, based on which a novel machine learning enhanced branch-and-price algorithm (BPL) is proposed, where prediction-based cuts are embedded to accelerate the pricing procedure. Experiments on real-scale instances demonstrate that the algorithm consistently achieves near-optimal solutions, with a gap of 4.42% on average from the best-found lower bound, and reduces computation time by over 90% compared to directly solving the IP model by CPLEX.

Our developed approach identifies the optimal curbside space allocation planning strategies to enhance passenger-level services, considering the <em>Curb Productivity Index</em> and the uncertain arrival distribution of Shared-Use Mobility (SUM) service units throughout the curbside networks.

Unfortunately, few studies in the literature have systematically analyzed causal structure characterizing the evolution of traffic states over time and gauged the importance of traffic nodes from a causal perspective, particularly in the context of large-scale traffic networks. Moreover, the dynamic nature of traffic patterns necessitates a robust method to reliably discover causal relationships, which are often overlooked in existing studies. To address these issues, we propose a Spatio-Temporal Causal Structure Learning and Analysis (STCSLA) framework for analyzing large-scale urban traffic networks at a mesoscopic level from a causal lens. The proposed framework comprises three main components: decomposition of spatio-temporal traffic data into localized traffic subprocesses; a Bayesian Information Criterion-guided spatio-temporal causal structure learning combined with temporal-dependencies preserving sampling for deriving reliable causal graph to uncover time-lagged and contemporaneous causal effects; establishing several causality-oriented indicators to identify causally critical nodes, mediator nodes, and bottleneck nodes in traffic networks. Experimental results on both a synthetic dataset and the real-world Hong Kong traffic dataset demonstrate that the proposed STCSLA framework accurately uncovers time-varying causal relationships and identifies key nodes that play various causal roles in influencing traffic dynamics.

Considering the pre-existing multi-modal transit network in a city, we have integrated analytical methodologies and mathematical programming to formulate a two-stage approach for addressing the bi-modal express transit network design problem (ETNDP) within the context of a surface express transit system. In the first stage, we use analytical approaches and continuum approximations to identify the optimal locations of new stations. In the second stage, mathematical programming is proposed to simultaneously determine the optimal layout of express transit routes, the technology of each transit route, and the service headway associated with all transit routes (i.e., existing and new routes). Then, a metaheuristic algorithm based on a Genetic Algorithm is introduced to solve the proposed mathematical programming for real-size transit networks. The proposed approach has then been applied to the express transit network of Calgary, Canada, a large-sized bi-modal express network. The bi-modal ETNDP has been solved for Calgary under various scenarios, and the results have been discussed. Analyses show that, in the proposed hybrid approach, solving a part of the problem analytically reduces its complexity significantly and enables parametric analysis, while using mathematical programming helps to address the complexity of ETNDP for real transit networks.

By utilizing low-altitude airspace, novel aerial vehicles can provide faster transportation between vertiports in urban and suburban areas, offering a more efficient alternative than traditional surface transport. To successfully integrate UAM into urban environments, it is crucial to effectively connect it with existing road transportation systems, particularly in terms of constructing essential ground infrastructure, such as vertiports. This paper proposes a land-air collaborative network design model that incorporates environmental considerations. Specifically, we develop a bi-objective bi-level programming model to optimize the land-air integrated operations. The upper-level authority aims to minimize both the total travel time of the system and airborne pollutant emissions during UAM operations by selecting the locations and capacities of vertiports. The lower-level model determines the route choices of the multi-class commuters based on the user equilibrium condition. To solve this model, we propose a mixed-integer Bayesian optimization approach, incorporating a path-based solution algorithm using the partial linearization descent method to address the lower-level model. Numerical experiments demonstrate that incorporating environmental considerations significantly influences the design of the land-air collaborative network. In particular, environmental factors play a critical role in shaping commuters’ route choice, which in turn substantially affects key system metrics such as vertiport capacity, total travel time, and air pollutant emissions.
