自主控制是科普生产和物流日益复杂的一种方法。自主控制方法的特点是在一个分层的组织结构中分散协调物流对象。自治对象本身能够处理信息,以便自己做出和执行决策。到目前为止,在这一领域的研究主要集中在自主控制方法的影响,忽略了他们在现有的规划系统的集成。因此,它是目前不可能给出一个实证的建议,规划和自主控制方法的组合实现了足够程度的物流目标的实现在不同复杂性的生产系统。在自主控制方法领域中的现有评估系统主要停留在定性水平上,而忽略规划系统。为此,本文提出了一个定量化、立体化的评价体系。首先,它操作的复杂程度,在生产系统取决于车间条件和干扰。其次,本文对生产系统的自治度进行了操作化。因此,它考虑了规划和控制水平之间的耦合类型和强度。第三,定义了一个衡量物流目标实现和计划完成程度的绩效指标向量。其结果是一个评估系统,它允许一个完整的定量评估生产系统中的自主控制。此外,考虑的重点从单纯的控制层面扩展到计划和控制层面。规划和控制方法之间的耦合强度对自主性的影响也被考虑在内,并可操作。最后,将该评估系统示例性地应用于已发表的模拟研究。
Autonomous control is an approach to cope with increasing complexity in production and logistics. Autonomous control methods are characterised by decentralised coordination of logistic objects in a heterarchical organisation structure. Autonomous objects themselves are capable of processing information in order to make and execute decisions on their own. Up to now, research in this field mainly focuses on the effects of autonomous control methods disregarding their integration in existing planning systems. Thereby, it is currently not possible to give a substantiated recommendation, which combination of planning and autonomous control methods achieves a sufficient degree of logistic objective achievement in production systems of different complexity. Existing evaluation systems in the field of autonomous control methods remain on a mainly qualitative level disregarding the planning system. Therefore, this paper presents a quantitative, three-dimensional evaluation system. First, it operationalises the degree of complexity in production systems depending on shop floor conditions and disturbances. Second, the paper operationalises the degree of autonomy of production systems. Thereby, it considers the type and intensity of coupling between the planning and control level. Third, a vector of performance indicators is defined to measure the logistic objective achievement and the degree of plan fulfilment. The result is an evaluation system which allows a complete quantitative evaluation of autonomous control in production systems. Furthermore, the focus of consideration is expanded from the mere control level to the planning and control level. The influence of the strength of coupling between planning and control methods on the autonomy is also taken into account and operationalised. Finally, the evaluation system is exemplarily applied to a published simulation study.
