Abstract

Given the flexible and configurable characteristics of smart manufacturing systems with a limited time per manufacturing task, the assumption of infinite time for prostems is no longer applicable to the joint-control strategy. Consequently, a joint-control model that considers production, inspection, and maintenance within a finite-time scenario for smart manufacturing systems is proposed in this paper. The objective is to optimize overall production and maintenance functions to minimize the total system cost. Comparing the joint strategy under infinite time with the proposed finite-time approach reveals significant differences in unit costs between the two scenarios. To enhance the effectiveness of the model, a discrete iterative algorithm with multiple loops was developed. Through a case study, it was observed that 1) joint strategies implemented within a finite time horizon were more cost-effective than those under infinite time, thus emphasizing the need for business managers to develop strategies within a finite time frame; 2) different production planning and efficiency levels had varying effects on the final joint strategy, necessitating customized strategies based on different production durations. Overall, the research gap regarding joint strategies within a finite-time context was addressed in this research, serving as a methodological foundation for practitioners to develop various strategies that minimize total costs across diverse real-world scenarios.

鉴于智能制造系统具有灵活可配置的特点，且每项制造任务的时间有限，因此，假定人造系统时间无限的假设不再适用于联合控制策略。因此，本文提出了一种联合控制模型，该模型考虑了智能制造系统有限时间场景下的生产、检查和维护。其目标是优化整体生产和维护功能，使系统总成本最小化。将无限时间下的联合策略与所提出的有限时间方法进行比较，可以发现两种方案在单位成本上存在显著差异。为了提高模型的有效性，我们开发了一种具有多个循环的离散迭代算法。通过案例研究发现：1）在有限时间范围内实施的联合战略比在无限时间范围内实施的联合战略更具成本效益，因此强调了企业管理者在有限时间范围内制定战略的必要性；2）不同的生产计划和效率水平对最终联合战略的影响各不相同，因此有必要根据不同的生产持续时间制定定制战略。总之，本研究填补了有限时间背景下联合战略的研究空白，为实践者在不同的现实世界场景中制定各种总成本最小化战略奠定了方法论基础。

期刊介绍： Elsevier publishes Reliability Engineering & System Safety in association with the European Safety and Reliability Association and the Safety Engineering and Risk Analysis Division. The international journal is devoted to developing and applying methods to enhance the safety and reliability of complex technological systems, like nuclear power plants, chemical plants, hazardous waste facilities, space systems, offshore and maritime systems, transportation systems, constructed infrastructure, and manufacturing plants. The journal normally publishes only articles that involve the analysis of substantive problems related to the reliability of complex systems or present techniques and/or theoretical results that have a discernable relationship to the solution of such problems. An important aim is to balance academic material and practical applications.
