The principles of control include the principle of standardity, the principle of timeliness, the principle of flexibility, and the principle of key points. The timeliness of control can enable managers to detect or even predict the occurrence of deviations as early as possible and correct them in time, so as to minimize losses in all aspects.

3. The principle consistent with the plan: the plan is the basis for realizing the control work, and the control itself also needs a plan. The more detailed, clear and feasible the plan is made, the easier it is to control. The completion of the control process is to make the actual activities consistent with the planned activities.

4. Maximize the control requirements of the accused object. Giving full play to the function of plc and maximizing the control requirements of the accused object is the primary prerequisite for the design of the plc control system, which is also the most important principle in the design.

5. What are the basic principles of power distribution system design? Next, Zhongda Consulting will introduce it to you in detail for your reference. ( 1) The low-voltage power distribution system should meet the requirements of power supply reliability and power quality required for production and use. At the same time, it should pay attention to simple wiring, convenient operation and safety, and the level of the power distribution system should not exceed the second level.

Briefly describe the principles of system design

The principles of flexibility and variability. Flexibility refers to the ability of the system to adapt to changes in the external environment. Whether a system can play a role and have strong vitality depends to a large extent on whether it is acceptable to management.

The overall design of the system should be based on the design idea of system engineering, so that the developed system can meet the overall requirements of scientific, rationalization and economy. Generally, the following basic principles are followed.

Comprehensive principle: The design of mechatronics system needs to consider factors such as mechanical, electrical, electronic and computer to ensure the comprehensiveness of the system.

The principle of pro-systematization; the principle of applicability; the principle of advancedness; the principle of low cost; the principle of reliability;The principle of multiple uses in one machine. Logistics is the whole process of planning, implementing and controlling the flow and storage of raw materials, intermediate products, final products and related information from the place of production to the place of consumption.

The principles of system design include

the principles of flexibility and variability. Flexibility refers to the ability of the system to adapt to changes in the external environment. Whether a system can play a role and have strong vitality depends to a large extent on whether it is acceptable to management.

. The principle of autonomy and controllability. Network security and confidentiality are related to the sovereignty and security of a country, so network security products cannot rely on foreign products. 7. The principle of safety and value. The design of the network system is limited by funds.

Take advanced technology, practical system, reasonable structure, mainstream products, low cost and low maintenance as the capital construction principles, and plan the overall framework of the system.

When designing a performance management system, the following principles should be followed: The principle of goal consistency: The design of the performance management system should be consistent with the company's strategic goals and business needs, ensure that the performance goals of employees are consistent with the overall goals of the company, and be able to target the performance of employees. Evaluate.

Business-based: When designing e-commerce systems, we should take business as the main focus, supplemented by technology, and take technology as a means to meet business needs and achieve business goals.

The basic principles of system analysis and design are the principle of uniformity. In accordance with the regulations and policies of the State Administration of Taxation on export tax refunds, taking into account the specificities of local business processing, a unified export tax refund business norms are formulated.The principle of applicability.
