本文对泰山三期核电站装卸料机台架仪控试验与现场运行条件一致性进行了研究。将试验台架上的标定结果直接运用到现场燃料操作系统,有效地缩短了更换装卸料机后的标定时间,减少了现场工作人员辐射剂量。消除了原有装卸料机更换方式造成机组降功率的风险。 相似文献

企业中的核心控制权与一般控制权 总被引:14,自引:0,他引:14
企业中资产所有者与人力资本所有者之间的控制权安排是企业制度安排的重要内容,但现有文献对此问题的研究存在大量的争论。本文在现有控制权理论研究的基础上将企业的控制权划分为核心控制权与一般控制权,并以此为基础,分别探讨了这两类控制权的配置关系。本文认为,企业契约中核心控制权的配置是基于对权力外部性风险的控制,而一般控制权的配置则是基于核心控制权行使的边际收益与边际成本的均衡。 相似文献

We discuss algorithmic control and nudges prevalent in the gig economy in relation to extant management control literature. We draw on an analysis of archival data and interviews with drivers and executives of app‐based cab companies in India. Comparing algorithmic control with direct control, we explain the increase in the scale and scope of automation that enables detailed driver profiling and segmentation, which is crucial for microtargeting control mechanisms and controlling driver earnings. Explaining nudges vis‐a‐vis indirect control, we highlight the role of mental processes and clarify the labelling of control mechanisms as nudges. Furthermore, we show how nudges are interwoven into algorithmic control as they capitalise on and feed into it. We also substantiate the discussions on information asymmetry by explicating the calculative apparatus that underlies the asymmetry. 相似文献

凹版印刷机张力控制系统是一个非线性、强耦合、时变性的复杂系统,用普通的PID难以达到理想的控制效果。本研究通过建立凹印机张力控制模型和驱动电机模型,设计了一种基于解耦控制原理的自适应解耦控制算法,根据偏差和偏差变化率来实时自适应追踪调整PID控制器参数,有效提高了张力控制系统性能和速度,是一种简单易行的控制算法。 相似文献

Organizational control scholars have recently noted how control use is not singular in organizations, but rather, different types of control are used to achieve different purposes. In international joint ventures (IJVs), we suggest that output, process, and social control are exercised by both foreign and local parent firms. We then hypothesize that a parent firm's usage of these three control types is influenced by its resource contributions. Using a sample of IJVs in China, we find that property‐based contribution is linked with output and process control, and knowledge‐based contribution is related to process and social control. The results also show differences in control practices between foreign and local parent firms. The findings provide important implications for the design and implementation of control systems in IJVs. 相似文献

R. Whittington 《R&D Management》1991,21(1):43-53
This article reports a comparative study of six in-house and eight independent industrial R&D organisations. These organisations are analysed in terms of three types of control strategy - market control, hierarchical control and professional control. The paper suggests that the professional control strategy, emergent after World War Two, is now being increasingly challenged by market control strategies. R&D organisations under or adopting market control are shown to enjoy marked productivity advantages. The distinctive managerial practices of market controlled R&D are analysed. It is concluded that many in-house laboratories have much to gain by partial adoption of these market control practices. 相似文献

This article investigates the organisation of work under algorithmic control in the platform economy. Based on a 1-year ethnographic study conducted at top food-delivery platforms in China, this study finds two main mechanisms for organising labour under algorithmic management: the virtual organisation of labour and algorithm-driven labour process control. First, platform drivers are reorganised in an outsourced labour force, placed in application-based virtual-networked production under sophisticated technological infrastructure. Second, to habituate drivers to the virtual mode of production, food-delivery platforms utilise four algorithm-driven control techniques, which are identified as: smart machinery control, information monopoly, management by multi-stakeholders, and ‘carrots and sticks’. The findings highlight the process of algorithmic design in configuring a digital managerial ecosystem for platform governance and contribute to emerging debates on algorithmic management. 相似文献
