Special Issue Information

Dear Colleagues,

Industrial management involves processes related to allocating resources, managing production timelines, and monitoring efficiency across manufacturing operations. For these processes to succeed in practice, scheduling models and algorithms play a pivotal role in optimizing the efficiency and effectiveness of all activities. In recent years, advanced planning and scheduling approaches based on real-time data integration have been used to automate, simulate, and optimize scheduling by dynamically adapting to changes and disruptions. Using constrained-based approaches, symbolic rules are introduced to accommodate machine downtime and workforce availability, paving the way for advanced algorithmic techniques to find practical solutions.

This Special Issue considers all scheduling approaches related to industrial management problems, including theory, models and algorithms.

Topics of interest include, but are not limited to, the following:

  • Constraint-based scheduling;
  • Dynamic scheduling models;
  • Metaheuristics, hybrid, and memetic algorithms;
  • Effective communication and monitoring;
  • Mathematical programming techniques;
  • Novel evaluation approaches and frameworks.

Knowledge-intensive projects in research and development (R&D), software, and high-technology sectors are delivered by knowledge workers who each command several skills. When many such projects compete for a shared pool of multi-skilled workers, and neither project arrival times nor durations are known in advance, deciding who works on what at each moment becomes a sequential decision problem. Therefore, we propose the multi-skilled, multi-project dynamic scheduling problem with random project arrivals and uncertain durations and formulate it as a Markov decision process (MDP) that minimizes the total human resource cost. Since the cost-to-go function is computationally intractable, we develop a rollout-based approximate dynamic programming (ADP) algorithm that approximates it via Monte Carlo simulation embedded with a randomized base policy and restricts the action space to ten representative allocation policies. On benchmarks extended from the Project Scheduling Problem Library (PSPLIB), the proposed policy lowers the average total cost by 3.1% to 16.7% relative to Q-learning on medium- and large-scale instances while completing more projects with shorter delays; on small-scale instances Q-learning attains a lower nominal cost, revealing a trade-off among cost, completion rate, and delay.

This study considers a 1-m-1 hybrid flow shop scheduling problem that simultaneously incorporates four practical constraints: lot streaming, no-wait, blocking, and sequence-dependent setup times. Although each of these characteristics has been studied individually in the literature, their joint consideration in a single HFS model has received little attention. The problem is motivated by a real-world order sequencing problem in insulation board manufacturing, where all four constraints arise simultaneously from the production process. To formally characterize the problem, we develop a mixed-integer programming formulation that captures all operational constraints. For practical-scale problems, we propose several dispatching heuristics that can obtain sufficiently good solutions within a short computation time. We further develop a genetic algorithm as an independent solution approach to obtain high-quality solutions close to the optimum within a reasonable computation time. Computational experiments on instances generated based on real insulation board production characteristics demonstrate that the proposed algorithms outperform a benchmark greedy rule, and sensitivity analyses reveal the effects of setup time magnitude and the number of parallel machines on scheduling performance.

Job shop scheduling holds significant importance due to its relevance and impact on various industrial and manufacturing systems. Aiming at the job shop scheduling problem with random machine breakdowns, a multi-objective optimization model is established, which considers both the makespan and expected makespan delay simultaneously. Considering that the expected makespan delay cannot be calculated analytically, this paper proposes a symbolic regression-based construction method, which can automatically learn a surrogate evaluation measure. Then, a multi-objective evolutionary algorithm is proposed for solving this model, where the constructed surrogate evaluation measure is used to replace the expected makespan delay for fitness evaluation, to achieve rapid evaluation and efficient optimization. Finally, extensive simulation experiments are conducted on 40 benchmark problems of job shop scheduling, which verify the effectiveness of the proposed method and its advantages in computational efficiency.
