This paper provides a systematic overview of machine learning methods applied to solve NP-hard Vehicle Routing Problems (VRPs). Recently, there has been great interest from both the and operations research communities in solving VRPs either through pure or by combining them with traditional handcrafted heuristics. We present taxonomy studies on paradigms, solution structures, underlying models, algorithms. Detailed results state-of-the-art are presented, demonstrating their competitiveness approaches. The survey highlights advantages learning-based models that aim exploit symmetry VRP solutions. outlines future directions incorporate solutions address challenges modern transportation systems.

Job-shop scheduling problem (JSP) is a mathematical optimization widely used in industries like manufacturing, and flexible JSP (FJSP) also common variant. Since they are NP-hard, it intractable to find the optimal solution for all cases within reasonable times. Thus, becomes important develop efficient heuristics solve JSP/FJSP. A kind of method solving problems construction heuristics, which constructs solutions via heuristics. Recently, many methods leverage deep reinforcement learning (DRL) with graph neural networks (GNN). In this paper, we propose new approach, named residual scheduling, remove irrelevant machines jobs such as those finished, that states include remaining (or relevant) only. Our experiments show our approach reaches state-of-the-art (SOTA) among known on most well-known open FJSP benchmarks. addition, observe even though model trained smaller sizes, still performs well large sizes terms makespan. Interestingly experiments, zero makespan gap 49 60 instances whose job numbers more than 100 15 machines.

Background: Logistics operations are integral to manufacturing systems, particularly in the transportation processes that occur not only between facilities and stakeholders but also warehouses workstations within a facility. The design of functional areas allocating goods appropriate zones warehouse management system (WMS) critical activities substantially influence efficiency logistics operations. Methods: This study develops mixed-integer programming (MIP) model optimize material flow product routing manufacturing. identifies efficient pathways, assigns products routes, determines required material-handling equipment. It is implemented Python (3.11.5) using Pyomo (6.7.3) package CBC solver (2.10.11), with sensitivity analysis performed on constraints decision variables evaluate robustness. Results: findings indicate Material Flow 3 Material-Handling Equipment 1 represent optimal configurations for managing majority system. Conclusions: proposed mathematical supports decision-making process by enabling adjustments proportions system, ensuring operational flexibility response changing demands. Furthermore, offers managerial insights suggests directions future research.
