MEASURING OVERALL EQUIPMENT EFFECTIVENESS

OEE计算
Overall Equipment Effectiveness shows “the amount or productive rvice that equipment provides”. It quickly highlights where improvement can be pursued. Analyzing the pieces that make up the OEE calculation will provide guidance on where to identify caus of loss or waste, and eliminate them.
OEE显示了设备提供的数量或生产性服务。它能较快地突出需要改善的地方。分析OEE计算的各项，能为识别损失或浪费原因，并消除这些原因提供指导。eba
OEE is a mathematical measure that combines Equipment Availability, Performance (Speed), and Quality so that you can e the combined effect on equipment operation.
OEE是结合设备可用率，表现率（速度）和合格率的数学计算，可以看到设备运转的综合效应。
OEE = Availability x Performance x Quality Rate
设备综合效率=可用率X表现率X合格率
In theory, equipment could operate at 100% OEE, but in real life this is virtually impossible. Initially you should not be surprid if equipment OEE is very low. Over time as you track the measure and apply the improvement process to root caus of waste and loss, you will drive the number higher. Remember this measure is a strong indicator of bottom line performance, so even small sustainable gains will drive gains in productivity, cost, machine availability, and energy u.
理论上，设备可以以100%的OEE运作，但实际生产中这是不可能的。刚开始，如果设备OEE很低，无需感到惊讶。随着你跟踪计算，改善浪费和损失的根本原因，就能提高数值。记住，这个计算是最低性能的指示，所以即使小幅度的持续增长，也能为产量，成本，机器可用率和能源使用带来改进。

Availability
可用率
Availability reflects the amount of time a piece of equipment is i can saying noactually in operation versus the amount of time it was scheduled to be in operation.
可用率反映了设备实际工作的时间占计划工作时间的比例
Availability = Scheduled Operating Time – Downtime = Actual Operating Time
Scheduled Operating Time Scheduled Operating Time

计划工作时间 计划工作时间
Scheduled Operating Time is the amount of time the equipment should be in operation.
It does not include periods of planned “employee” downtime like meetings, breaks, and meals. It does not include periods of time when the equipment is intentionally not staffed, becau of a decision not to operate it (this includes idle time due to shortage of labor or attendance issues).
计划工作时间是设备应该运转的时间。不包括计划的人工停机，如会议，休息和用餐时间。也不包括设备没有配备，而决定不运作的时间（这包括由于人员或出勤问题导致的闲置时间）。
Downtime is any period of unplanned downtime. This includes breakdowns, minor stoppages, lack of material, and machine tups and adjustments (considered unplanned since the goal in Lean is zero tup and adjustment). If preventive maintenance (PM) occurs during a period or time when the equipment is scheduled to run and caus downtime, it is included as unplanned (one goal of PM programs is to utilize normal downtime periods for performance of PM).
停机时间是所有计划外停机的时间。包括故障，短暂停机，缺物料，机器安装调整（由于
精益生产的目标是零安装调整，所以认为是计划外停机）。如果在设备计划运转的时间里进行PM并造成停机，这也被认为是计划外的（PM的一个目标是在正常停机时间内进行PM）。
Subtracting the unplanned downtime from the Scheduled Operating Time gives you the Actual Operating Time, when the equipment was in operation and cycling to perform work.
当设备运转时，计划工作时间减去计划外停机时间，得到实际工作时间。
For example: 例如：
Suppo during an eight hour shift (480 minutes) a winder was scheduled to be shut down for 55 minutes (20 minute lunch, 2 times 10 minute breaks, 5 minute department meeting, and a 30 minute preventive maintenance activity (the first 20 minutes performed during the planned lunch break downtime period). The Scheduled Operating Time would be:
假设工作时间是8小时（480分钟），绕线机计划停机55分钟：20分钟午餐时间，2次10分钟的休息，5分钟部门会议，和30分钟的预防性维护活动（前20分钟在午餐时间进行）。由此可得，计划工作时间是：
Gross Available Time (work period) 480 minutes
Scheduled Downtime (shutdowns) -45 minutes (10 minute of PM will be Unplanned)2011年河南高考分数线
Scheduled Operating Time 435 minutes
可用时间（工作周期） 480 分钟
英语数字单词计划停机时间（停机） -45 分钟 （10分钟的PM是计划外的）
计划工作时间 435分钟
Suppo during the 435 minutes of Scheduled Operating Time the equipment breaks down for 20 minutes. There is a 15 minute shutdown due to lack of material, a 20 minute 澳门留学

changeover to a new part, and the equipment is not producing for 10 minutes while the operator troubleshoots a quality concern. The Actual Operating Time would be:
假设在这435分钟的计划工作时间内，设备故障20分钟。由于缺少物料停机15分钟，20分钟换新零件，设备因操作工解决质量问题停机10分钟未生产。由此可得，实际工作时间是：
Scheduled Operating Time 435 minutes

Actual Operating Time 360 Minutes
计划工作时间 435 分钟
