机器停机时间，无论是计划内的还是计划外的，对制造组织来说都是直观的成本，但通常很难量化。成本计算过程很少在制造业组织中进行。据此前估计，80%的工业设施无法准确计算停机时间，许多设施将总成本低估了200-300%（Crumrine and Post 2006）。人们还认识到，缺乏实用指南阻碍了任何性质的成本计算程序更容易地实施（Dale和Plunkett，1995年）。确实存在的模型很少考虑其他地方确定的成本的子集，导致过于保守的估计。此外，由于费用定义不一致，以前没有适当界定评价和量化各项费用的方法。本文概述的工作旨在制定第一个全面的方法来确定停机时间的成本，特别适用于澳大利亚邮政的自动邮件处理机。所提出的方法可以应用于任何制造环境，这将受益于更全面地了解机器或过程停机时间的成本大小。
Machine downtime, whether planned or unplanned, is intuitively costly to manufacturing organisations, however is often very difficult to quantify. Costing processes are rarely undertaken within manufacturing organisations. It has previously been estimated that 80% of industrial facilities were unable to accurately cost downtime, with many facilities underestimating the total cost by a factor of 200-300% (Crumrine and Post 2006). It was also acknowledged that the lack of practical guides has hindered costing procedures of any nature being implemented more readily (Dale and Plunkett 1995). Models that did exist rarely considered more than a subset of the costs identified elsewhere, leading to overly conservative estimations. In addition, because cost definitions are not consistent, methodologies for evaluating and quantifying individual costs have not previously been adequately defined. The work outlined in this paper has aimed to develop the first comprehensive methodology for determining the cost of downtime, with particular application to the Australia Post’s automated mail processing machines. The method presented may be applied to any manufacturing environment which would benefit from a more complete understanding of the magnitude of the cost of machine or process downtime.
