Optimization of equipment life cycle cost

Abstract equipment life cycle cost refers to the cost incurred in the whole process of equipment planning, manufacturing, installation and commissioning, use, maintenance, transformation and scrapping, including original cost and usage cost. In order to achieve the goal of optimizing the life cycle cost of equipment, several aspects must be done: (1) ensure the optimization of life cycle cost in the whole process of equipment; (2) Implement comprehensive management of equipment from the aspects of technology, economy and organization; (3) Focus on the reliability and maintainability design of equipment; (4) Implement the whole process management of the equipment; (5) Pay attention to the information feedback in the process of equipment working cycle

in order to optimize the life cycle cost of equipment, several aspects must be done well

1. Ensure the optimization of life cycle cost in the whole process of equipment

the life cycle of equipment refers to the whole process of equipment from planning, manufacturing, installation and commissioning, use, maintenance, transformation to scrapping. The life cycle cost of equipment refers to the total cost consumed in the whole process of equipment, which is composed of original cost and usage cost. The original fee (setup fee) is a one-time expenditure or concentrated expenditure in a short period of time. Self made equipment includes research, design and manufacturing costs; The purchased equipment includes the price, transportation, installation and commissioning costs. The usage fee (operation and maintenance fee) is the fee paid regularly to ensure the normal operation of the equipment, including energy fee, fixed asset tax, insurance premium, maintenance fee, operator's salary, etc. Therefore, when making equipment operation decisions, we should not only consider the economy of a certain stage of the equipment life cycle (manufacturing, procurement, use and maintenance), but also pay great attention to the most economical sum of the original cost and usage cost of the equipment. For example, when designing a new equipment, we should not only consider reducing the manufacturing cost, but also consider the economic and reasonable use cost; When choosing new equipment, we should not covet cheap prices, but also take into account a series of other costs after the purchase of the equipment. In fact, the cheapest purchase price does not necessarily mean the lowest life cycle cost, and the best life cycle cost does not mean the lowest life cycle cost. Factors such as the production efficiency of the equipment and the assurance degree of output and quality should also be considered. In practical work, economy and technology are dialectically unified. Because economic benefits are the direct driving force to promote the development of production tools, only new machines and equipment with advanced technology and reasonable economy can be widely used. Therefore, the planning, purchase, use, renewal, transformation and other links of equipment management must be analyzed for economic benefits according to the principles of advanced technology and reasonable economy, as a basis for evaluating many schemes The main basis for selection and decision-making, which is also an important way to improve economic benefits

2. Comprehensive management of equipment from the aspects of technology, economy and organization

comprehensive management of equipment by integrating the factors of technology, economy and organization is the objective need to manage, use, repair and operate modern equipment well. With the continuous improvement of the modernization level of equipment, there are more and more categories of equipment and devices that embody science and technology. Not only do various specialized technologies develop in depth, but also all kinds of specialized technologies are required to be integrated horizontally. Therefore, in terms of technology, we must master a variety of science and technology to become one expert and versatile; In terms of economy, pay attention to improving the economic effect of equipment management, and analyze the economic problems existing in each link of equipment management, including the economic analysis of equipment selection, the economic standard of reasonable use, the economic problem of inspection times, the economic limit of repair, etc; In terms of organization and management, it involves the relationship between people. We must study the organizational personnel and management system, and formulate a set of management methods such as industrial operation, overall planning, quality control and value analysis

in order to ensure the efficient, trouble free, safe and pollution-free operation of the equipment, the fan blade industry consumes more than 1million tons of composite materials every year, and optimize the life cycle cost of the equipment, it is very necessary to establish the comprehensive management of the equipment. At present, the division of labor in the internal organization of Chinese enterprises is often divided according to the professional and functional business system, resulting in the disconnection of equipment management and their own policies. In other words, the concept of comprehensive management of horizontal connection has not yet been formed. Only by solving the comprehensive management of horizontal connection can we ensure the optimization of equipment life cycle cost

3. Focus on the reliability and maintainability design of equipment

reliability means that the equipment is accurate, safe, reliable and trouble free in operation. Maintainability refers to easy maintenance, including simple structure and reasonable combination of parts and components; The repair channel is good, which can be quickly disassembled and easy to check; High level of generalization and standardization, strong interchangeability, etc. its purpose is to improve the availability of equipment. The ideal limit of the reliability and maintainability of the equipment is the design without maintenance, and it will be scrapped after a certain period of use. At present, some equipment has reached the ideal limit of no maintenance. Through the development of maintenance free design technology, the structure of the equipment can be simplified under the condition of ensuring high performance, high efficiency and high precision. Therefore, the general trend of equipment development is a dialectical development process of simplicity, complexity and simplicity

4. Implement the whole process management of the equipment

the whole process management is to expand the scope of equipment management to include the whole process of the research, design, manufacturing, purchase, installation and commissioning, use, maintenance, transformation and scrap of the chuck attachment equipment, so as to ensure and improve the reliability, maintainability and economy of the equipment as a whole. The whole process management of equipment is an important direction of equipment management reform in China

5. Pay attention to the information feedback in the process of equipment working cycle

in equipment management, the equipment user department timely and accurately feed back the situation in the process of equipment use to the equipment manufacturing department, so as to improve the equipment design and continuously improve the performance and quality of the equipment

there are two kinds of information feedback in the process of equipment working cycle. One is off-site feedback, which refers to the feedback from the user department to the manufacturing department. In the process of equipment use and maintenance, the user department accurately feeds back the information about equipment reliability, maintainability, resource consumption, man-machine cooperation and other aspects to the manufacturing department, and then the manufacturing department actively carries out equipment management activities for all staff, user access and user service; Second, the feedback in the plant is directed at all chassis components of bentler Automotive Industry Co., Ltd. and bentler Sigri, which refers to the feedback from the user of self-made special equipment to the equipment design and manufacturing unit in the plant

in a word, through the scientific management measures of technology and economy, we should comprehensively manage the important production equipment of the enterprise, so as to achieve comprehensive planning, reasonable allocation, selective purchase, correct use, careful maintenance, scientific overhaul, timely transformation and renewal, so that the equipment is often in a good technical state, and constantly improve and improve the quality of the technical equipment of the enterprise, so as to achieve the most economical cycle cost of the equipment and the highest comprehensive efficiency
