TPM management activities include six aspects: equipment maintenance, quality maintenance, personal improvement, transaction improvement, environmental protection and personnel training. Through the active participation of all employees, enterprises can be improved and promoted in all directions. TPM originated from PM (Preventive Safety) in the United States in 1960s, and TPM (Total Production Management) was developed and innovated in 198 1 and formed in Japan.
Meaning:
TPM is the abbreviation of English Total Productive Maintenance, and Chinese translation is Total Productive Maintenance and Total Productive Maintenance. Other TPM abbreviations plus this English word have nothing to do with this. TPM originated from PM (Preventive Safety) in the United States in 1960s. After the expansion and innovation of the Japanese, 8 1 formed the TPM (Total Production Management) of the whole company, which was a great success in Japan and then promoted all over the world. 199 1 year, the first TPM world congress was held in Tokyo, Japan, with more than 700 participants from 23 countries. TPM activity consists of six aspects: equipment maintenance, quality maintenance, personal improvement, transaction improvement, environmental maintenance and personnel training, which can improve the enterprise in all directions.
Origin:
TPM originated from Total Quality Management (TQM). Total quality management is the direct result of Dr. Edward Deming's influence on Japanese industry. Shortly after World War II, Dr. Deming went to Japan to start his work. As a statistician, he was initially responsible for teaching Japanese how to use statistical analysis in their manufacturing industry. Then how to use the data results to control the product quality in the manufacturing process. The initial statistical process and its quality control principles were quickly influenced by Japanese professional ethics, forming a way of industrial survival with Japanese characteristics. This new manufacturing concept eventually formed the well-known TQM, in which the early TPM was related to equipment maintenance. TPM is the beginning of PM production safety introduced by Denso Japan (with several companies in Tianjin) in 196 1 year. Seven years later, the company decided to involve all employees and carry out full security. After more than two years of hard work, it achieved great success, so TPM was born.
Development:
When TQM requires equipment maintenance as one of the inspection elements, it seems that TQM itself is not suitable for maintenance environment. This is because preventive maintenance (PM) measures have been taken seriously for quite some time, and most factories also adopt PM. Moreover, the technology of using PM technology to make maintenance plan to keep the equipment running normally has matured. However, when it is necessary to increase or improve the output, this technology often leads to excessive maintenance of the equipment. Its guiding ideology is: "If a drop of oil can be better, then more oil should be better". In this way, improving the running speed of equipment will inevitably lead to an increase in maintenance workload. However, in the usual maintenance process, the role of operators is rarely or never considered, and only the contents specified in the commonly used and imperfect maintenance manual are trained for maintenance personnel, and no additional knowledge is involved. By adopting TPM, many companies quickly realize that it is not enough to meet the manufacturing needs only by planning maintenance. In order to solve this problem under the premise of following TQM principle, it is necessary to improve the original TPM technology and bring maintenance into the whole quality process.
Development stage:
The first important stage of development
Post-event repair (BM) stage (time: before World War II to 1950)
The second important stage of development
Preventive maintenance (PM) stage (time; 1950 - 1960)
The third important stage of development
Production maintenance (PM) stage (time: 1960-1970)
The fourth important stage of development
Total Production Maintenance (TPM) stage (1970 till now).
Skills:
First of all, to create changes in the production site, the most critical factor is that if enterprises want employees to actively participate in management strategies, they must create local changes and eliminate employees' cognitive blind spots. In other words, managers create rapid changes in the field department, so that employees can see these changes at the first time, thus enhancing their confidence in improving activities and improving work efficiency. Secondly, guide employees to actively participate in improvement, because obviously, enterprises can't achieve their goals only by relying on the strength of a few managers in improvement. In this case, employees need to participate in the improvement of the enterprise, so as to play the best effect. If employees can't see the development prospect in the enterprise, or their own value can't be reflected in the enterprise, then they are unlikely to make progress with the enterprise. Therefore, enterprises should encourage employees and give them enough trust, so as to stimulate their enthusiasm and let them join the ranks of improvement. Finally, enterprises should constantly set higher goals. In order to clarify the effect of TPM activities, enterprises should master the principle of step by step. However, in reality, some enterprises often make the mistake that if they set their goals high from the beginning, employees will not only feel out of reach, but also lose their confidence and motivation to improve, and eventually the improvement activities of enterprises will end in failure. In fact, the most scientific method is to constantly set higher goals, and the process of continuous improvement needs to be gradual. Enterprises should put forward different goals at appropriate times according to the implementation of improvement, and gradually improve the level of goals, thus improving efficiency.
Element:
1, TPM is committed to the goal of maximizing the comprehensive efficiency of equipment; ?
2.TPM is jointly implemented by all departments;
3. Total productive maintenance involves every employee, from top management to on-site staff;
4.TPM is promoted by incentive management, that is, independent group activities.
TPM is an on-site improvement activity to fully pursue the production efficiency limit of enterprises.
1. Take 5S activities as a breakthrough, and lay a solid foundation for TPM management. In view of the traditional ideas that metallurgical enterprises have always been regarded as "stupid, big, black and rough" and "dirty, chaotic and poor", we chose 5S activities as a breakthrough and focused on three special rectifications. Rectify the "dirty, chaotic and poor" production site and purify the working environment; Rectify the "running, leaking, dripping and leaking" and "dirty, loose, lacking and rusty" of the equipment to improve the physical quality of the equipment; Rectify the power pipe network in the factory and create a brand-new corporate image. 2, grasp the typical demonstration to lead the way, drive the general, comprehensive promotion. It is not enough to limit TPM management to the rectification of 5S activities and think that 5S activities will do TPM management well. In order to advance to a higher level, we adopted the "twelve-character working method" of "learning, comparing, coding, popularizing, checking and consolidating" and followed the principle of "from simplicity to complexity" from single equipment to large units, and successively cultivated and established 53 typical demonstration machines such as water pump stations, substations, cranes, hydraulic stations and instrument rooms. These machines have extensively established and improved the regional TPM management responsibility system, and the environmental sanitation, hidden trouble handling, lubrication and fastening, regular oil change and maintenance are all done by people, which fully embodies the TPM management concept of full participation.
Standard:
16 years, and the previous generation standards TPM1.2,201/0 years. Compared with TPM 1.2, TPM2.0 has better compatibility and higher security. If you want to use TPM2.0, you need to have a security chip that conforms to TPM 2.0 standard in your computer, so a complete TPM 2.0 module can be understood as TPM 2.0 standard+security chip. The main function of TPM module is encryption, and the key is generated by the encryption algorithm built in the chip, which can effectively protect the computer and prevent illegal users from accessing it. At the same time, due to the storage capacity of TPM chip itself, some computer fingerprint identification and disk encryption functions will also be realized through TPM module. If you want to confirm whether your computer has a tpm 2.0 module, you can enter tpm.msc in the run command to open the TPM Manager to view the TPM module. At present, TPMTPM 2.0 module is widely used in notebook computers, but rarely in desktops, because even if the desktop supports TPM 2.0 module, it will be turned off by default. If it is turned on, it is very simple, just turn it on in the BIOS of the motherboard. Generally, in the advanced options of computers, taking ASUS motherboard as an example, we enter the PCFW setting of advanced options. You can see the PTT option after the advanced entry, because the domestic consumer motherboard does not provide TPM chips for policy reasons, so it needs the support of the processor. PTT is an Intel processor that simulates TPM function. The PTT option in the BIOS defaults to "Turn on the independent TPM", which is actually to turn off the PTT option, and the "Turn on" option behind it is the real turn on. Precautions will appear when turning on Intel PTT, and TPM 2.0 will also turn on after turning on PTT. PPT is turned on because there is no TPM chip, so many consumer motherboards will provide TPM slots, which can be solved by purchasing TPM 2.0 modules separately. However, due to the demand of Windows 1 1, the price of TPM 2.0 module has soared recently. However, according to China's policy, TPM modules are rarely sold in the market at present. The prudent TPM2.0TPM2.0 you want to buy is actually not the exclusive technology of high-end platforms. Now many new computers come with TPM 2.0, which only needs to be adjusted manually. But many old computers really don't have TPM2.0, and they need to be upgraded if they want to experience it. This practice of bundling sales will be offensive. But obviously, increasing the burden on users for the so-called data security cannot make most people buy it.
Features:
Compared with the original maintenance, the total production maintenance in Japan mainly highlights the word "all", which has three meanings, namely, full efficiency, full system and full participation.
The so-called total efficiency refers to the life cycle cost assessment and comprehensive efficiency of equipment, which will be discussed later in this chapter. The whole system refers to all aspects of production and maintenance, such as preventive maintenance, preventive maintenance, necessary after-the-fact maintenance and improved maintenance. Full participation refers to the mass characteristics of this maintenance system, from company managers to relevant departments to all operators, especially the independent group activities of operators.
The main goal of TPM is "total efficiency", which is to limit and reduce six major losses:
(1) Equipment downtime loss (downtime loss).
(2) Set and adjust the downtime loss.
(3) Idling, idling and short-term downtime losses.
(4) Deceleration (speed loss).
(5) Loss of defective products, defective products and waste products, and loss of leftover materials (defect loss).
(6) Output loss (interval time from installation to stable production).
With these three "all" words, production and maintenance will be more thoroughly implemented, and the goals of production and maintenance will be more effectively guaranteed. This is also the uniqueness of total production maintenance in Japan.
With the continuous development of TPM, Japan has raised the goal of this top-down, system-wide equipment management system to a higher level and put forward: "Don't stop! Waste is zero! The accident is zero! " The goal of struggle.
