摘要

生产周期的缩短和技术创新的影响越来越大，促使生产线调度方法的改进。提出的研究目的是一个决策模型的建议，使灵活的反应不断变化的生产条件。中心决策被在独立机器级别上执行的决策所取代。这些机器利用的有关其技术邻居的能力利用情况的信息相当有限。决策遵循在进化过程中重新编码的决策表(决策染色体)。模型背后的遗传算法能够识别出高度可接受的解决方案，并通过一系列模拟实验证明了这一点。这组独立的机器成为自组织的，对生产线的产能利用率有显著的积极影响。去中心化方面使我们的建议与该领域的其他研究有所不同。这一理念建立在这样一个事实之上，即每台机器都是根据在给定时间内可用的信息做出生产决策的。在生产流程中，柔性机器对其相邻机器的产能利用率(给定生产机器之前和之后的机器)做出反应。©2020 CPE，马里博尔大学。版权所有。

Decentralized optimization of the flexible production lines

The shortening of the production cycle and increasing impact of the techno‐ logical innovations evokes improvement of the methods used in the produc‐ tion line scheduling. The aim of the presented research is a proposal of the decision model that enables a flexible reaction to the changing production conditions. The central decisions are substituted by the decisions performed on the independent machines level. The machines utilize rather restricted information on the capacities utilization of their technological neighbours. The decisions follow the decision tables (decision chromosomes) re‐coded in the course of the evolution. The Genetic algorithms standing behind the mod‐ el, enable identification of the highly acceptable solutions that is proved by a set of the simulation experiments. The set of independent machines becomes self‐organized, having a significant positive effect on the production line ca‐ pacities utilization. The decentralization aspect makes our proposal some‐ what different from other research in the field. The philosophy is built on the fact that each machine makes its production decision based on the available information, which it has at its disposal in a given time. The machine flexible reacts to its neighbours' capacity utilization (machine before and after given production machine) in the production process flow. © 2020 CPE, University of Maribor.

期刊介绍： Advances in Production Engineering & Management (APEM journal) is an interdisciplinary international academic journal published quarterly. The main goal of the APEM journal is to present original, high quality, theoretical and application-oriented research developments in all areas of production engineering and production management to a broad audience of academics and practitioners. In order to bridge the gap between theory and practice, applications based on advanced theory and case studies are particularly welcome. For theoretical papers, their originality and research contributions are the main factors in the evaluation process. General approaches, formalisms, algorithms or techniques should be illustrated with significant applications that demonstrate their applicability to real-world problems. Please note the APEM journal is not intended especially for studying problems in the finance, economics, business, and bank sectors even though the methodology in the paper is quality/project management oriented. Therefore, the papers should include a substantial level of engineering issues in the field of manufacturing engineering.
