Manufacturing and service organisations improve their processes on a continuous basis to have better operational performance. They use lean six sigma (LSS) projects for process improvement. Therefore, this study aims to investigate the existing literature in LSS and the application of big data analytics (BDA) to have more confident and predictable decisions in each phase of LSS. Fifty-two articles have been identified after a careful and vigilant screening of closely related themes. Future research directions in the big data and LSS have been highlighted on the basis of organisational theories. Review presents an investigation framework consisting of BDA techniques applicable to each phase of LSS in all the dimensions such as volume, variety, velocity and veracity of big data. Review highlights the concerns of big data in LSS such as system design and integration, system performance, security and reliability of data, sustaining the control and conducting the experiments, distributed material and information flow. The review unveils the application of 8 modern organisational theories to big data in LSS with 21 key aspects of related theories and 19 distinct research gaps as opportunities for future research. 相似文献

It is intuitively appealing to measure downtime in terms of total time lost (i.e. frequency times duration). However, the same total downtime can be produced by an infinite number of frequency/duration combinations. This study reports the findings of a computer simulation study on the impact of varying combinations of downtime frequency/duration pairs on performance of serial production systems. The research reported here clearly shows that different downtime frequency/duration combinations affect serial production lines differently even when the total downtime remains equal. Analysis suggests that long duration, infrequently occurring variation has a much more negative impact on system performance than short duration, frequently occurring variation. 相似文献

ABSTRACT Much has been written recently concerning the future of statistics in business and industry (e.g., Technometrics 2008). In this expository article, the authors extend this discussion to focus specifically on the future of statistics and statisticians within the context of quality improvement. We argue that though the problems our profession faces are well known and have been repeatedly identified in the literature, the underlying root causes of these problems have remained lurking under the surface of the discussion. In particular, though positive change is certainly taking place, we do not believe that the statistics community has fully accepted and come to grips with the radical changes in our environment over the past 20–40 years. In short, we believe that our environment has changed radically, whereas our own changes have been incremental in nature. One such change that seems particularly difficult for us to swallow is that our society needs us to function, especially in the quality arena, more as an engineering discipline, rather than primarily as a pure science. To the extent that we can make this transition, we believe that we will maintain and grow our vitality as a discipline. To the extent that we refuse to, or are unable to, make this transition, our vitality, influence, and impact may erode, as other disciplines fill the void we leave. We choose to view this situation as half full and therefore offer specific suggestions as to how we feel the profession can make the needed changes in order to secure a brighter future in quality improvement. 相似文献

This paper aims to develop a unifying and quantitative conceptual framework for healthcare processes from the viewpoint of process improvement. The work adapts standard models from operation management to the specifics of healthcare processes. We propose concepts for organizational modeling of healthcare processes, breaking down work into micro processes, tasks, and resources. In addition, we propose an axiological model which breaks down general performance goals into process metrics. The connexion between both types of models is made explicit as a system of metrics for process flow and resource efficiency. The conceptual models offer exemplars for practical support in process improvement efforts, suggesting to project leaders how to make a diagrammatic representation of a process, which data to gather, and how to analyze and diagnose a process's flow and resource utilization. The proposed methodology links on to process improvement methodologies such as business process reengineering, six sigma, lean thinking, theory of constraints, and total quality management. In these approaches, opportunities for process improvement are identified from a diagnosis of the process under study. By providing conceptual models and practical templates for process diagnosis, the framework relates many disconnected strands of research and application in process improvement in healthcare to the unifying pursuit of process improvement.

精益六西格玛(Lean Six Sigma, LSS)作为持续改进与创新的有力工具,在业界(制造业、建筑业、服务业甚至非盈利性组织)得到广泛的应用,但学术界和产业界对LSS的认识和理解仍存在一些差异。为了构建对LSS更为全面的认识,基于Web of Science 数据库中题目含有“六西格玛”或“精益六西格玛”的2701 篇文献分析,简要回顾LSS的起源,系统梳理LSS在理论研究和产业界应用的现状,给出6个主要的研究内容。结合LSS在中国的应用实践,并从战略、系统和集成3个角度展望LSS的未来发展趋势,期望对精益六西格玛的学术研究和产业应用提供指导和参考。 相似文献

6σ改进主要应用于现有的过程或产品, 而6σ设计主要应用于设计或重新设计过程或产品;何时优先采用6σ设计方法一直是一个备受争议的问题.为解决这一问题,比较了6σ改进和6σ设计方法的差异;进而从系统论的观点,分析了选择6σ方法时需要考虑的要素并建立了相应的指标体系;在此基础上,引入了多目标决策的层次分析方法,并对一个6σ项目进行了分析.结果表明,选择6σ方法受到许多因素的影响,从而替代了6σ文献中"只有达到4.8σ,才能实施6σ设计"的准则.结论是任何实施6σ管理的组织可以根据技术、顾客需求、成本、复杂性、风险等因素,选择适应于自身发展的6σ方法. 相似文献

The importance of the six sigma methodology in industry is growing constantly. However, there are few empirical studies that analyse the advantages of this methodology and its positive effects on organisational performance. The purpose of this paper is to extend understanding of the success of six sigma quality management initiatives by investigating the effects of six sigma teamwork and process management on absorptive capacity. It also seeks to understand the relation between absorptive capacity and organisational learning as two sources of sustainable competitive advantage. The information used comes from a larger study, the data for which was collected from a random sample of 237 European firms. Of these 237 organisations, 58 are six sigma organisations. Structural equation modelling (SEM) was used to test the hypotheses. The main findings show that six sigma teamwork and process management positively affect the development of absorptive capacity. A positive and significant relationship is also observed between absorptive capacity and organisational learning orientation. The findings of this study justify six sigma implementation in firms. This study provides us with an in-depth understanding of some structural elements that characterise the six sigma methodology, enabling us to provide an explanation for its success. 相似文献
