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。 The goal pursued by people's development automation is to enable people to emancipate people in repeated physical or mental labor and reduce production and reduce costs, while improving production 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。 The so-called productivity should not only be understood as yield level per unit time, and should be an economic concept, productivity is that between consumption work in a device on the cost of the equipment and the production value in quantity, the value shall be measured in the form of currency and contrast. 2、自动化的经济性； 2, the 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 scheme of automation only when the cost is reasonable to economic conditions, is in each specific case, to prove its economic efficiency improved; at the same cost, the output value per unit time is improved; or in unit time value is the same, the cost is reduced. Only after proving that equipment or process methods with high degree of automation have economic benefits, it is of great significance to their application.
