In many cases it is quite literally a question of life and death, whether in the context of safety and security or associated with the viability of business activity. As a result, location modeling has become essential in system understanding, designing or extension in whatever way spatial choice is considered. Location modeling too is central in addressing sustainability, resilience, efficiency and effectiveness across a range of urban and environmental contexts. Over the past three decades geographic information systems, and more generally GIScience, has emerged as a critical complement to location modeling. This paper seeks to articulate and demonstrate how GIScience is now a central component of location modeling, one that fundamentally bridges geographic information systems and optimization in many ways. GIScience primitives are formally structured and specified in order to make linkages explicit in the context of location modeling. This is significant as GIScience helps to further establish locational theory and principles that form the basis of model extension as well as enables better solution approaches to be developed.

Thus, the scheduling of the periodic chains is a principal problem in time-triggered Ethernet, like IEEE 802.1Qbv Time-Sensitive Networks. This paper studies a strongly NP-hard periodic scheduling problem with harmonic periods, task chains, and dedicated resources. We analyze the problem on several levels and provide proofs of complexity and approximation algorithms for several special cases. We describe a solution methodology to find a feasible schedule that minimizes the chains’ degeneracy related to start-to-end latency normalized in the number of periods. We use the local search with the first fit scheduling heuristic, which we warm-start with a constraint programming model. This notably improves the schedulability of instances with up to 100% utilization and thousands (and more) of tasks, with high-quality solutions found in minutes. An efficient constraint programming matheuristic significantly reduces the degeneracy of the found schedules even further.

Routing flexibility, a crucial advantage of FMS, enabling a job to be handled via alternative machine combinations, is involved. To address this problem, we propose a novel hybrid approach using Ant Colony Optimisation (ACO), which employs a two-element vector structure to model the ACO decision nodes. Each node represents an operation from a job assigned to a particular machine. During the ACO process, to decide a node for next movement, an ant first assesses potential nodes through a node scheduling procedure with two consecutive steps: firstly, using a heuristic vehicle assignment method, an AGV is designated and scheduled for the operation specified in a node. Following this, based on the established transportation timeline, the operation’s production schedule on the assigned machine is determined. Subsequently, the node selection is guided by the pheromone information on potential paths and the heuristic data of potential nodes derived from their scheduling information. To avoid local optima, multiple heuristic rules are incorporated in the ACO, with one chosen randomly for node selection each time. Numerical tests show that our proposed approach outperforms contemporary metaheuristic approaches in the literature.

Our methodological framework comprises 3 modules: (i) an efficient data handling and storage process to manage a large volume of data and ensure data tractability; (ii) a novel mixed-integer linear programming model to effectively solve the aircraft routing problem within 1 to 5 min of computation, even at large instances; (iii) a multi-objective algorithmic framework that effectively employs parallelization techniques to generate Pareto-optimal frontiers within 30 min of computation. The three components are integrated into an unified decision support tool that empowers airline managers to visualize and evaluate various aircraft routing solutions, considering multiple objectives simultaneously while leveraging the use of multi-criteria methods.

Phase II uses the HESI and proposes three versions of priority weights for different application scenarios. These are used as the priority weights to formulate a capacitated location problem with a multimodal network and multiple types of refrigerators. The model considers additional factors like storage capacity, locations, transportation distances (including air and ground options), costs (maintenance and transportation), and vehicle capacity. To solve the model for large networks, the paper suggests a solution approach using Benders Decomposition with extreme directions. To validate the models, we examine the case of COVID-19 vaccine distribution in India. To assess the impact of the Susceptibility Index on facility locations, proposed weightage versions are compared with a version that does not use the index. The results show that one of the three versions with weighting schemes based on the population-to-susceptibility ratio leads to the most cost-effective distribution strategy, ensuring coverage of all susceptible regions.

Unlike most existing studies that focus on a single container flow, this study investigates the cooperative scheduling of internal container trucks (ICTs) and railway cranes (RCs) for multiple container flows. A mixed-integer programming model is developed to minimize the maximum completion time, the waiting time of external container trucks (ECTs), and the transportation time of ICTs. To generate an optimized baseline schedule, a Multi-Objective Particle Swarm Optimization (MOPSO) algorithm is employed. From a practical operational perspective, however, the baseline schedule must effectively address uncertainties in real-time. Therefore, we propose a proactive-reactive and global-local hybrid rescheduling strategy based on digital twin (DT). The DT facilitates uncertainty monitoring, rescheduling plan generation, simulation, and iterative optimization. The hybrid strategy consists of: (1) a global rescheduling optimization model, which is proactively triggered periodically or reactively triggered due to cumulative errors, aiming to maximize schedule stability; and (2) a local short-interval recovery policy, which is reactively triggered to handle uncertainties occurring between two consecutive global rescheduling points. A case study is conducted to demonstrate the effectiveness of the proposed rescheduling strategy in handling delayed ECT arrivals and other uncertainties. The results highlight the efficiency of the DT-enhanced methodology in improving RC and ICT collaboration. Sensitivity analysis further identifies appropriate threshold settings and equipment configurations.

Due to increasing environmental awareness of customers and government regulations, car sharing providers must be careful about the composition of their vehicle fleet to meet diverse customer demand through vehicle types with different carbon emission levels. In this study, for a car sharing company, we consider the problems of determining service regions and purchasing decisions with a mixed fleet of vehicles under budget and carbon emission constraints, and the deployment of these vehicles to service regions under uncertain one-way and round-trip rental requests over a multi-period planning horizon. We further introduce the concept of “substitution” to the car sharing operations that provides customers with alternative vehicle options when their preferred type is unavailable. To address this complex problem, we propose a novel two-stage stochastic mixed-integer program leveraging spatial–temporal networks and multicommodity flows to capture these strategic and operational decisions of this system over the planning horizon while allowing substitution in operations. We further prove that the corresponding second-stage problem of the proposed program has a totally unimodular constraint matrix. Taking advantage of this result, we develop a branch-and-cut-based decomposition algorithm with various computational enhancements. We present an extensive computational study that highlights the value of the proposed models from different perspectives and demonstrates the performance of the proposed solution algorithm with significant speedups.

However, the issue of temporal workload imbalances caused by instantaneous differences in processing time between zones has not been addressed. Since temporal workload imbalances result in delays, this study proposes the decomposition of workloads into time slots and develops a temporal workload balancing model (TBM) that incorporates batching and sequencing based on time slot decomposition. We also develop an adaptive large neighborhood search (ALNS) heuristic model to tackle large-scale practical problems of temporal workload imbalance. In simulation experiments, we compare the TBM model to alternative batching strategies in an order picking environment featuring consecutive batch windows.
