Introduction
With the development of the market economy and increasing competition, people do not only demand the products are cheap and good, but also importance to the reliability and safety of the products. For example, Japanese cars, household appliances and other products, although in terms of performance and price, are similar as ours, but they can occupy the US and international markets. The main reason is that Japan's product reliability is better than China. People advocate brand-name products, which is the best embodiment of pursuing high-reliability products. A product with good reliability can not only reduce the company's maintenance costs, but also quickly become a well-known brand, significantly enhance the company's image, enhance core competitiveness, increase the company's revenue, and survive and develop in the fierce competition. For the economic transformation and the gradual strengthening of China, the reliability issue must be highly valued for the government and enterprises. We must accelerate the popularization of reliability knowledge, so that engineers and technicians can deeply understand and skillfully apply reliability knowledge, and achieve rapid integration. Apply to the actual product, thus greatly improving the reliability level of our products.
Course Purpose
Every aspect of the product has reliability problems from design, manufacture to use. If statistical analysis, measures, and work are carried out at every stage, the impact of these factors will be minimized, and the reliability of the product will be obvious improved. Customers will be more satisfied. The role of learning and applying reliability technology to the enterprise is as follows:
1. Conducive to improve product quality can produce more reliable products that customers are more satisfied with, thus increasing market share;
2. Conducive to ensuring the reliability and maintainability of high-performance, high-precision, large-scale complex products;
3. Conducive to the development and development of new products, to achieve lower life cycle costs, shorter development time, etc.;
4. Improve product stability by improving product reliability;
5. Reduce economic losses caused by product quality and reliability issues, and improve economic efficiency.
This course is a basic course in the design, development and analysis of reliability products. It is practical and provides a lot of real examples, enabling participants to master the basic principles and knowledge and share practical experience in a relaxed and active atmosphere. And skills, and increase the gains in communication. The course content mainly includes: basic concepts and key terms of reliability, common life distribution and identification, guarantee analysis for life data, reliability test plan, multiple failure modes, parameter methods for common life distribution analysis, and common life distribution analysis. Non-parametric method, reliability analysis of repairable system, basic theory of accelerated life test and its statistical analysis method, analysis and establishment of reliability model, reliability index and its internal relationship, selection and demonstration of reliability index, establishment of reliable Sexual model procedures, determine product definitions, block diagram analysis, fault tree (FTA), build reliability models, P-Diagram, reliability indicator demonstration, allocation and estimation, Six Sigma reliability design brief, reliability management profile, etc.
Theoretical research on reliability requires a lot of advanced statistical knowledge. For general application personnel, it is difficult to fully understand these statistical theories in a short period of time, but MINITAB software will explain that we specifically implement these analyses. There is no need to understand the advanced theory. The best way to learn reliability is to combine learning methods with practical problems. It is important to understand the concepts, learn to use software to calculate and analyze, and understand the meaning of calculations and analysis results.
Participants:
Failure analysis engineer, reliability engineer, quality engineer, process engineer, R&D engineer, automatic control engineer, power maintenance engineer, product test engineer, qualification engineer, engineering and quality manager, product manager and related management personnel.
Course Objectives:
l Introduce the basic concepts and key terms of reliability and key terms to the students the basics of reliability.
l A series of design, development, production, testing and management work to achieve product reliability requirements. And for the feedback information, propose an improvement suggestion.
l Combining engineering practice and case study, we can make a difference, integrate and understand the essence of reliability work.
l Use short time to quickly find defects in product reliability and propose improvements.
l Improve the reliability of work efficiency, enhance the reliability of work, and achieve the goal of reducing the life cycle cost.
l Reliability design and analysis with the statistical software MINITAB reliability module, making work efficient and fast.
