Purpose

The purpose of this study is to investigate the benefits of the turning point layout; a simulation model being applicable for strategic level is designed that compares systems with and without turning points. Specifically, the avoidance of deadlocks and prevention of conflicts is substantial.

Design/methodology/approach

Optimization process for different layouts and configuration of autonomous guided vehicles (AGVs) are worked out using statistical methods for design parameters. Regression analysis is used to find effective design parameters and analysis of variance is applied for adjusting critical factors. Also, the optimal design is then implemented in a manufacturing system for an industrial automation and the results are reported.

Findings

The outputs imply the effectiveness of the proposed approach for real industrial cases. This research will combine both simulation-based method and optimization technique to improve the quality of solutions.

Originality/value

In AGV systems, the begin-end combinations are usually connected by using a fixed layout, which is not the optimal path. The capability of these configurations is limited and often the conflict of multiple AGVs and deadlock are inevitable. By appearing more flexible layouts and advanced technology, the positioning and dispatching of AGVs increased. A new concept would be to determine each path dynamically. This would use the free paths for AGVs leading to overcome the conflicts and deadlocks.

机器人工业自动化仿真-解决冲突和死锁的优化

目的

本研究的目的是调查转折点布局的好处；设计了一个适用于战略层面的模拟模型，比较有和没有转折点的系统。具体来说，避免僵局和预防冲突是非常重要的。

设计/方法/方法

自动导引车 (AGV) 的不同布局和配置的优化过程使用设计参数的统计方法制定。回归分析用于找到有效的设计参数，方差分析用于调整关键因素。此外，然后在工业自动化的制造系统中实施优化设计，并报告结果。

发现

输出结果表明所提出的方法对实际工业案例的有效性。这项研究将结合基于模拟的方法和优化技术来提高解决方案的质量。

原创性/价值

在AGV系统中，始端组合通常采用固定布局连接，这不是最优路径。这些配置的能力有限，多台AGV的冲突和死锁往往在所难免。更灵活的布局和先进技术的出现，增加了AGV的定位和调度。一个新概念是动态确定每条路径。这将使用 AGV 的自由路径来克服冲突和死锁。
