人们发展自动化所追求的目标是使人们不断重复的相同体力或脑力劳动中解放出来，并且在减少劳动量和减少费用的同时，大量地提高产量和质量。 People develop automation goal is to make people keep repeating the same physical or mental work, and at the same time, reduce labor and reducing the cost in a large number of to improve yield and quality. 1、生产率； 1. Productivity; 所谓生产率不应仅仅理解为单位时间内产量地高低，而应是一个经济性的概念，生产率是指在一台正常工作的设备上所消耗的费用与该设备所生产的产值在数量上的对比，这个数值应以货币形式来衡量和对比。 So-called productivity should not be simply interpreted as high and low yield per unit time, and should be an economy, the concept of productivity refers to the devices in a normal work consumed cost and on quantity of output produced by the device of comparison, this value should be measured in monetary form and contrast. 2、自动化的经济性； 2. Economy of automation; 自动化的技术方案只有在其费用是经济合理的条件下才能实现，也就是要在各种具体情况下，证明其经济效益有所提高；即在费用相同时，单位时间的产值得到提高；或者在单位时间内产值相同时，费用有所减少。只有证实了自动化程度较高的设备或工艺方法具有经济效益之后，对于它们的应用才具有意义。 The technical solution of automation can only be realized under the conditions of economic rationality, which is to prove that its economic benefits are improved in various circumstances. That is, the output value of the unit time is improved at the same time. Or the cost per unit of time is reduced. Only if the high degree of automation equipment or process has economic benefits, the application of them is meaningful.
