Cycle time 周期
In manufacturing, cycle time is the time period when an operation begins to when it ends. 在制造业中，周期是指一个运营从开始到结束的时间段。
Manufacturing try to make operations more efficient to cut cycle time. 制造部门努力提高生产效率，以缩短生产周期。
If an operation started on Monday and finished on Wednesday, its cycle time was two days. 如果运营是从周一到周三，那么周期是两天。
【选择】-Why do manufacturers try to reduce on the cycle time? -To make operations more efficient.
【填空】The manager was dissatisfied because the operation's cycle time took two days longer than expected.
error-proofing 防错技术
Error-proofing involves taking measures to prevent defects in a process. 防错技术是一个通过检测技术来防止缺陷的过程。
During error-proofing, possible errors that an operation can generate are identified. 在防错技术中，操作可能产生的错误会被鉴定出来。
An example of error-proofing is a machine shutting down automatically if it malfunctions. 防错技术的一个例子是，一台机器发生故障后自动关闭。
Six Sigma 六西格玛
Six Sigma is a method that is used to improve the quality of a business's products or services.
It commonly follows a five-step methodology: define, measure, analyze, improve, and control.
Manufacturers use Six Sigma to identify and remove production defects.
If a product has a defect, the root cause will need to be identified and a solution implemented.
Afterwards, the solution will be monitored to see if the problem was fixed.
【选择】-What is the first step in error-proofing? -indentifying potential issues.
【选择】-What is Six Sigma used to improve？ -the quality of products or services
【填空】Defects cause materials to be wasted, but through error-proofing we can prevent that from happening in the first place.
Cell 车间
A cell is a grouping of people, supplies, and machines used to manufacture products.
Cell improve efficiency and prevent overproduction in a manufacturing process.
Because a cell is closely grouped, defects can be identified and fixed faster.
【填空】In a cell, people, supplies and machines are arranged in close proximity.
Radio Frequency Identification 射频识别
Radio frequency identification, or RFID, uses radio waves to send and receive information. 射频识别，简称RFID，使用无线电波来发送和接收信息。
RFID technology can check components from suppliers, improving shipping accuracy before manufacturing.
It identifies the misplaced items in real-time, which reduces the impact of human error in production.
It can be used to synchronize production flow so that production lines can run smoothly. 它可以用来同步生产流程，使生产线能够顺利运行。
【填空】The RFID system identified that there were 20 bags of sugar missing from the shipment.
