Taking equipment as the research object, we pursue the comprehensive efficiency of equipment, apply a series of theories and methods, and take a series of technical, economic and organizational measures to scientifically manage the whole process of material movement and value movement of equipment (from planning, design, selection, procurement, installation, acceptance, use, maintenance, repair, transformation, renewal to scrapping).
Equipment management is the focus of enterprise internal management; Equipment management is the guarantee of enterprise production; Equipment management is the basis for enterprises to improve efficiency.
2. Information management
File management is one of the five functions of the operating system, which mainly involves the logical and physical organization of files, the structure and management of directories. The so-called file management is a set of software in the operating system, managed files and some data structures needed for file management.
3. Storage management
The object of memory management is main memory, also called memory. Its main functions include allocating and reclaiming main memory space, improving the utilization rate of main memory, expanding main memory and effectively protecting main memory information.
4. Operation management
Activity-based activity management is the starting point and core of enterprise management, which is much more profound than the traditional product-based enterprise management, and can be regarded as a major change and breakthrough in enterprise management.
The effective implementation of activity-based management depends on the information support provided by activity-based costing; However, if the advanced and distinctive activity-based costing is not combined with the emerging activity management, it will have little effect on the continuous improvement of production and operation activities and the continuous improvement of benefits.
5. Process management
There are essential differences between concurrent programs and sequential programs. In order to better describe the concurrent execution of programs and realize the concurrency and interest of operating systems, the concept of "process" is introduced.
Process is the running activity of a program with certain independent functions on a certain data set, and it is an independent unit of the system for resource allocation and scheduling.
Processor is the most important resource in a computer system. In modern computer system, in order to improve the system resource utilization, CPU will be monopolized by a program. Multi-channel programming technology is usually adopted, that is, multiple programs are allowed to run in the memory of a computer system at the same time.
