Collaborative robots (cobots) are important components of the Industry 4.0 paradigm and smart manufacturing. Cobots are known for their ability to interact with the operators in a shared workspace. Due to their spread in the last decade, cobot research proliferated. However, most individual studies focused on specific aspects of cobot deployment, and only scant attention was given to their evaluation (mostly not based on productivity criteria). Thus, better support is needed for cobot acquisition and deployment decisions. This paper answers this need by presenting a summary of the major considerations related to cobots acquisition and deployment, and providing a productivity analysis procedure that supports cobot acquisition and deployment decisions. Defining the cobots’ required characteristics and capabilities, effectively narrows the possible selection of cobots. However, it does not give information as to the economic value of acquiring and deploying a specific cobot. So, in addition to cobots’ characteristics and capabilities, this paper presents computational techniques to analyse and support this decision for a single workstation per se, and for a station in an assembly line. The difference between these two cases is discussed and analysed, and corresponding models are presented with computational examples.

在协作系统中部署协作机器人:主要考虑因素和生产力分析

协作机器人(cobot)是工业4.0范例和智能制造的重要组成部分。合作机器人以在共享工作空间中与操作员交互的能力而闻名。由于它们在过去十年中的传播,协作机器人研究激增。但是,大多数个人研究都集中在协作机器人部署的特定方面,而对其评估的关注却很少(大多数不是基于生产率标准)。因此,需要更好的支持来进行协作机器人的获取和部署决策。本文通过概述与协作机器人采购和部署有关的主要考虑因素,并提供支持协作机器人采购和部署决策的生产力分析程序,满足了这一需求。定义协作机器人所需的特性和功能,有效地缩小了协作机器人的选择范围。但是,它没有提供有关获取和部署特定协作机器人的经济价值的信息。因此,除了协作机器人的特性和功能之外,本文还提供了计算技术来分析和支持针对单个工作站本身以及装配线中某个工位的这一决策。讨论并分析了这两种情况之间的差异,并通过计算示例给出了相应的模型。
