Manufacturing is a solid foundation for realizing the Chinese dream. At present, China has established a complete, independent and complete industrial system, which effectively supports the economic and social development of our country and the improvement of comprehensive national strength. However, compared with developed countries, China's manufacturing industry still has gaps such as lack of innovation capacity, low level of industrial structure, large consumption of resources, and low quality and efficiency.
In today's world, the manufacturing industry is showing a trend of globalization, leanness, collaboration, service, green, and intelligence. Developed economies have established globally oriented resource allocation and product sales networks, built a group control model, and optimized resources. Configure to achieve lean operation.
Therefore, China's manufacturing industry is facing the pressure of industrial reform brought about by the rapid development of information technology and mobile Internet technologies. It faces the pressure of industrial restructuring and upgrading as China's economy enters the new normal, and faces the pressure of industrial competition brought about by the reindustrialization of developed countries. .
In the face of this situation, the CPC Central Committee and State Council brewed the "Made in China 2025" and made a top-level design for China's manufacturing industry. "Made in China 2025" proposes that based on national conditions, based on reality, and strive to achieve the strategic goal of manufacturing a powerful country through three steps.
Experts believe that the key to achieving a strong manufacturing nation is innovation-driven. The strategy of innovation drive has a bearing on the future and destiny of the Chinese nation. China's economic development must break through bottlenecks and resolve deep-level contradictions and problems. The fundamental solution lies in innovation. In 2016, the State Council issued the "Guiding Opinions on Deepening the Integration of Manufacturing Industry and the Internet" (hereinafter referred to as the "Opinions"), clearly stating that manufacturing industry is the main body of the national economy and the main battlefield for the implementation of "Internet +" actions.
The Opinions point out that China is a big manufacturing country and a major Internet country. Promoting the integration of manufacturing and the Internet is conducive to the formation of superposition benefits, syndication benefits, and double-benefit benefits. It will accelerate the conversion of old and new development kinetic energy and production systems, with broad prospects and huge potential.
Intelligent manufacturing starts at the source
Whether it is "manufacturing + Internet" or "Internet + manufacturing", its goal is to promote a new generation of information technology and manufacturing industry highly integrated revolution. "Made in China 2025" also regards smart manufacturing as the main direction and end result.
To realize the transformation and upgrading of the manufacturing industry, and effectively enhance the R&D and innovation capability are the key points and breakthrough points for the transformation of China's manufacturing enterprises.
Tian Feng believes that in the past, China emphasized quality efficiency and cost control in the manufacturing process. In fact, the design process also needs to pursue high quality, high efficiency, and low cost. It must extend lean thinking from manufacturing to R&D, and every aspect of R&D In the steps, we try our best to use the best solution to realize the highest value and lowest cost of design products.
Tian Feng pointed out that compared with the traditional R&D process, the lean R&D system is not suitable to consider and configure locally, but considers the entire design system and process from the overall, system, and optimization to achieve higher Horizontal design status.
He said: "We know that the core of lean production with a focus on production is to streamline the process, eliminate wastage in the production process with the least input, shorten the customer's response cycle, and increase corporate capital returns and corporate profitability."
However, there are three models for the driving force of industrial development. In addition to efficiency driving, there are demand-driven and innovation-driven. The former enhances the competitiveness of enterprises by improving efficiency and reducing costs. Both of the latter two are closely related to the design, and through the formation of innovative advantages, they will increase product technology, business, and brand added value, thus improving the competitiveness of enterprises.
There is always a bottom line to the cost, and there is much room for improvement in value. Therefore, lean R&D has more room for improvement than lean production.
Two phases of lean development
Tian Feng proposed the concept of "Lean R&D 2.0" for "Made in China 2025" in 2016. He said that it took about 10 years from the presentation of lean R&D to the present, during which it experienced the following two stages:
The first phase of lean R&D is Lean R&D 1.0. The obvious feature of this phase is the paradigm shift. For years of research and development accumulated by the enterprise, the R&D process has been linearized and digitized, and the hidden energy contained in the process has been released, and the R&D system has been backed up to achieve the purpose of consolidating management, improving efficiency, strengthening collaboration, and continuously improving. The so-called hidden energy refers to the knowledge, experience, R&D tools, quality requirements, and process data that are formed during the R&D process.
"If 1.0 is a system that promotes R&D efficiency, then 2.0 is a system that promotes innovation." Tian Feng said that the stage goal of 2.0 is the necessary positive design capability for enterprise technology development and product innovation, and it is also the second one for lean R&D. stage.
Forward design is relative to reverse design. The biggest difference between the two is that the starting point of the design is different. The forward design emphasizes starting from customer requirements, through functional decomposition, system design, physical design, product trial production, component verification, system integration, system verification, and system validation, until the completion of the acceptance of the products required by the stakeholders; and reverse design From the physical design, to focus on the completion of products.
Lean R & D 2.0 era
According to Tian Feng, most industrial enterprises in China currently have only backward design (ie, imitation) capabilities. The design process starts with the physical design of surveying, restoration and imitation, and has not experienced the important stages of the product's function and performance, such as the requirement definition, function analysis, and system integration of the product's forward design.
The 2.0 stage is devoted to clarifying all the elements of the R&D system and proposes a complete enterprise R&D system project model. Advocated through the introduction of the system engineering V model, focusing on the system design starting from the demand, and adopting the MBSE (model-based system engineering) method as the support of the system design, strengthening the comprehensive simulation and comprehensive experiments, and enriching the integrated design system.
It is reported that the Lean R&D 2.0 system framework is a comprehensive integration of lean R&D concepts, ideas, models, tools, technologies, and platforms, and is divided into 11 sub-systems.
According to Tian Feng, "Made in China 2025" proposes "promoting breakthrough development in the ten key areas." The common feature of these areas is that equipment and products are relatively high-end. At present, most of the high-end products represented by aircraft carriers, large aircrafts, and high-speed railways in China are large-scale and complex. The appearance of these products not only marks a significant increase in China’s industrial level, but also indicates the innovation of the manufacturing R&D system and technological transformation. Projects such as information, digitalization, integration and integration have played an important role in promoting industrial progress.
The increase in size and complexity of products poses higher requirements for R&D. It shows the features of full-scale, parallel, and comprehensive. In the past, the R&D system was unable to meet the needs, and it needed to break through the existing framework and innovate a new generation of industrial R&D systems. .
Tian Feng emphasized that lean R&D is different from lean production. Lean production focuses on the reduction of production costs, while lean R&D focuses on the increase of R&D value, followed by the reduction of R&D costs. More importantly, lean R&D is based on the product's full-cycle perspective, focusing on the reduction of costs, costs, energy consumption, and material costs.
The integration of the two is an important point of integration for the construction of a strong country and a powerful network. The integration of the two must make a difference, we must find an entry point and a foothold in the Internet + manufacturing to promote the sustainable development of the manufacturing industry. Internet + manufacturing is the power source for the integration of the two.
