1. Supply chain quality management
Figure 1: System architecture diagram
The framework is divided into 4 layers, as shown in Figure 1. The bottom layer is the IoT sensor layer, where GPS is used to locate products during logistics. Use RFID technology to record quality information, asset information and transaction information. Various sensors will be used to collect information about temperature, vibration, humidity, etc. Considering that many enterprises and CNC machines have their own information systems, some interfaces can be developed to obtain information from these different information systems.
The second layer is the data layer, including blockchain and distributed ledgers. Quality data, logistics data, asset data and transaction data are stored in the blockchain. Additionally, all businesses retain copies of supply chain data, including suppliers, manufacturers, logistics operators, retailers and financial institutions. Smart contracts can leverage this data to perform quality control and improve supply chain efficiency.
The third layer is the contract layer. Mere data sharing is not enough, data collection in the above layers not only facilitates data sharing but also aims to assist quality control and improve efficiency. Data sharing needs to consider privacy issues. Because competing companies operate on the same supply chain, some information may need to be kept confidential. Digital identities can be used to control access to data. Smart contracts can leverage on-chain data to perform real-time quality monitoring and automated logistics planning. In addition, business contracts can also be automatically executed based on transaction data and smart contracts.
The top layer is the business layer. Including various commercial activities in the enterprise, every enterprise in the supply chain can control and manage product quality with the support of blockchain and smart contracts, improving the efficiency and profits of the enterprise.
Case Study:
In this section, we use the laptop supply chain for a case study. Suppliers in the supply chain provide components to manufacturers, and based on data collected by IoT sensors and machine tools, production processes and product quality can be monitored in real time. In this way, suppliers and manufacturers can detect and control errors in a timely manner. As shown in Figure 2, quality data during the production process and inspection process will be uploaded and stored in the blockchain, quality data, process quality and product quality will be evaluated in real time through smart contracts, and the results will be sent back to suppliers, manufacturers and Retailers.
Figure 2: Real-time quality monitoring
Competing suppliers may offer the same type of components, such as CPUs or screens. Under the control of smart contracts, each supplier has its own digital identity with specific access rights to data on the blockchain. For example, Intel and AMD cannot access each other's data. As shown in Figure 3, companies in the supply chain can upload data without restrictions and control data access rights through smart contracts with digital identities, thus ensuring data privacy.
Figure 3: Digital Identity
There are also contracts between manufacturers and suppliers. For example, if the smart contract detects that certain products fail to meet the manufacturer’s requirements, these products will be automatically returned. As shown in Figure 4, the smart contract must be deployed on both sides, the contract will be automatically executed, and the execution results will be sent to the stakeholders when an unexpected error occurs.
Figure 4: Smart Contract
All suppliers on the blockchain will be able to access customer feedback on the product in order to adjust production.
During the logistics process, sensors detect environmental data, including temperature, humidity, etc., and GPS tracks product location. Based on this data logistics providers are able to use smart contracts to automatically plan their routes and transportation methods. As shown in Figure 5, suppliers and manufacturers upload transportation data, and smart contracts develop logistics plans based on the quantity and location of products.
Figure 5: Logistics plan
Retailers use smart contracts to monitor production processes and product quality. When internal failures occur, products are withdrawn; when external failures occur, retailers and manufacturers bear losses under their quality contracts. Manufacturers are also able to obtain final customer demand analysis and feedback to adjust production strategies. All these processes are automated through smart contracts.
Supply chain finance is another important component of the system. When a company encounters a financial gap, financial institutions can use asset data, logistics data and transaction data to provide product mortgage loans to companies in the supply chain. According to the loan contract, these mortgage products are protected by smart contracts. As shown in Figure 6, financial institutions can access loan data shared among suppliers, manufacturers, logistics providers, and retailers to assess a company's ability to repay loans.
Figure 6: Supply chain financial system
Therefore, blockchain and smart contracts establish a more reliable quality monitoring system, a more flexible end-customer demand feedback system and a more Safe and convenient supply chain financial system.
For the main data, we analyze the reasons for the factory quality management data
2. Will blockchain trigger the 4th industrial revolution
Chapter An industrial revolution brought steam power and factories. The second produced railroads and electricity. The third time gave us the internet, digital computers and the conveniences of the modern world.
These revolutions began and ended with the creation of better, more efficient machines. But the fourth revolution, Industrial Internet of Things (IIoT), asserts that it is coming, and it will not follow in the footsteps of its predecessors.
The focus of the fourth revolution will not be on stronger and faster machines: it will revolve around machines, processing, sharing, and spontaneous information behavior, fundamentally changing our relationship with tools, the world, and each other. relationship between.
Data Revolution
NoCoal, steel, and not silicon, the currency of the fourth revolution will be data.
A single gas turbine, coupled to the industrial Internet, generates more than four times the data of the entire world’s Twitter in a day, but we analyzed less than 1% of the data. Bill Ruh, CEO of GE Digital, predicts that there will be a deluge of digital information that today’s analytical tools cannot hope to parse.
“Ten years ago, we were probably bringing in 1 terabyte of data every day,” Ruh said in an interview with the Boston Globe. “Today, that’s up to about 10,000 terabytes of data. By 2020, we expect to be bringing in about 1 terabyte of data every day. Millions of terabytes of data.”
The machines of the future will produce roughly the same amount of information every day as the U.S. Library of Congress. Imagine reading every book in the Library of Congress and then having to summarize what you learned in 10 pages. The task is not only huge, it's ridiculous.
The real miracle of the fourth industrial revolution will not be the data produced, but the intelligent machines that can analyze this data and communicate with their kind in the network. Each networked machine will then take action, changing its processes to become more efficient and feeding its changes back to the network.
Hopefully these smart machines will bring our world economy to a climax: Ruh and GE believe that over the next 20 years, the smart machines and IoT industries will add $10 to $15 trillion to the global economy. This is a huge increase considering that global gross domestic product (GDP) was approximately $74 trillion in 2015.
The Foundations of the Revolution
Two components are focused and necessary for the coming revolution: a centralized, industry-specific Internet communications network such as General Electric’s Predix; decentralized approach, as well as hindering dishonest communications to facilitate commerce.
Specific IIoT networks must serve as hubs for intelligent machines to interact with each other and with their human creators. Sensors on computers collect large amounts of data and then sift through the data in real time. In other words, it is conceivable that it occurs on the basis of a machine. But to relay equipment findings and make decisions without human intervention, to truly create a smart network, machines need a single communications network.
Imagine that while the plane is still in the air, sensors in the plane's engine identify a part that is about to fail, then communicates to the destination airport that the engine will need maintenance and orders replacement parts before landing.
This kind of intuitive machinery is no sci-fi dream: it's our future.
I believe that IIoT information network is only half the battle, ultimately it is still about e-commerce. Think of it like public roads that millions of self-driving cars will one day be running on.
Right now, these self-driving cars run a single system. But how do we ensure that every self-driving car will obey traffic rules? For example, how do we ensure that in the event of an accident, the vehicle does not send false information about its whereabouts?What about deceptive information? If the accident happened between just two parties, then each passenger would corroborate his own car's story, and there would be no way to verify each party's claimed location.
Consider that decentralized, satellite-based GPS will impact the situation. This system is impartial and connected to every vehicle. Of course, each car can continue to lie, but it's much simpler to verify which side is telling the truth.
Due to the non-cancelable nature of the GPS system, self-driving cars have no reason, or have been tampered with by their owners, to lie about their location in the event of an accident. This strong incentive for integrity is tantamount to promoting trade among self-driving cars and is necessary to make owners feel that their investment in these vehicles is safe.
GPS technology is to autonomous vehicles what network blockchain technology is to the industrial Internet. Of course, self-driving cars can drive on the road without GPS, but their owners probably won't allow them to do so. Likewise, at a larger scale, machines can communicate on a single, centralized network of the Industrial Internet, but must do so without risk. (Blockchain BlockChain is the core part of Bitcoin BitCoin technology. Its function is simply similar to a ledger that records all transaction data. This ledger: 1. Stored on various Bitcoin nodes on the Internet, each node There is a complete backup; 2. It records all Bitcoin transfer transactions since the birth of Bitcoin; 3. The ledger is stored in blocks, and each block contains a part of the transaction record. Each block records the previous block. The id of the block forms a chain structure, so it is called a blockchain; 4. When you want to initiate a Bitcoin transaction, you only need to broadcast the transaction information to the P2P network, and the miners will record your transaction information into a The new block is connected to the blockchain and the transaction is completed.
Blockchain has spurred revolutions elsewhere
Of course, blockchain has facilitated the growth of e-commerce in the financial industry. But digital Packets of information are discrete assets like currency, and blockchain can create a digital record of their existence and transmission. The technology is essentially a record, or unified ledger of digital events. This ledger is dispersed across the network and is shared between different parties and can only be updated by a unanimous majority of those parties. Once a ledger item is created, it can never be erased.
Blockchain is the missing link in the revolution because it Incentivized e-commerce will define trust between machines and stakeholders. Take, for example, Volkswagen’s recent emissions scandal. Volkswagen’s tests showed that its vehicles emitted too much nitrogen oxide, so it chose to hide the problem to avoid subsequent inspections.
While blockchain will not prevent machines or humans from tampering with the data, it will create transparent, shared, and indelible documentation of the original emissions data. If this data has already been created and passed through the blockchain system By sharing, the public will never go down the path of fraud because the differences between the two data sets are obvious.
3. Blockchain can improve the transparency and flexibility of the supply chain
Today’s market competition has become increasingly dynamic and demanding, resulting in a challenging competitive environment. To adapt to this dynamic environment, supply chains increasingly rely on collaboration, integration, flexibility and trust among those taking over. Therefore, new technology applications are becoming increasingly important in supply chains.
In order to improve supply chain process control, Maoqiu Technology believes that modern professional applications must be implemented. Blockchain technology has become an essential part of today’s competitive environment. Companies should invest in blockchain technology to quickly respond to changing market conditions and demands in today’s dynamic business environment.
According to a paper report released by MDPI, blockchain solves the two main problems of traceability and transaction irreversibility in the supply chain, thereby effectively improving the transparency of the supply chain. Transparency, as a point of importance to all stakeholders in the supply chain, can ensure that product information can be viewed and obtained in a timely manner, and there will be corresponding losses caused by information delays.
Supply chain transparency is primarily based on information about the movement of products along the supply chain. If companies are to maintain the ability to proactively communicate with stakeholders to gain visibility and traceability of their supply chain operations, they can ensure visibility and visibility of information about products, services, financing and the flow of information from manufacturer to customer. Accessibility.
In the above manner, stakeholder feedback can be included in the blockchain to improve the performance capabilities of the supply chain. In addition, the history of a product can be tracked throughout the supply chain, and a clear picture of current activity can be displayed. Companies can confront environmental or social issues through transparency by articulating core values to reduce uncertainty in public markets.
Many stakeholders have high hopes for blockchain because of its capabilities such as real-time information sharing, security, immutability, and transparency. With its proof-of-work and distributed database structure, blockchain can increase supply chain transparency while using real-time distributed data sharing to enable stakeholders to identify product quality, location, deliveryEasy and program-related data.
These capabilities of blockchain enable product tracking, allow for comprehensive product verification and product authorization throughout the transaction process, and provide end-to-end auditing based on permissions across the organization. Blockchain reduces the opportunistic behavior of trading partners in terms of information tampering, corruption, fraud, etc.
Therefore, blockchain provides transparency in transactions between trading partners, thus increasing trust, and blockchain strengthens the relationship between suppliers, customers, outsourcing, The relationships between 3PLs and subcontractors make the supply chain more efficient and transparent.
Blockchain technology can help build trust and reputation by bringing transparency to supply chains. Large-scale blockchain solutions have the ability to completely redesign reputation management and detect fraud across entire networks. Blockchain consensus provides a solid foundation for the unification of opinions and the ability to achieve higher transparency. Establishing a decentralized supply chain based on blockchain technology instead of a centralized supply chain in the supply chain obviously has the advantages of being more efficient and transparent.
As supplies become more widely distributed, the risk of conflicts, mismatches and inconsistencies in traditional supply chains increases. Blockchain can allow for better tracking and reporting, increasing transparency in supply chain processes, thereby improving delivery schedules. For example, GPS-based vehicle tracking devices can be used with blockchain to provide the blockchain with data that cannot be overwritten and tampered with, which can reduce costs and increase efficiency when it comes to logistics vehicle tracking.
Contemporary supply chains are more complex, dynamic and uncertain than ever because they involve many departments. So creating a flexible supply chain is key to achieving sustainable competitive advantage. A flexible supply chain improves delivery processes and quickly moves products to required markets.
Business transactions are becoming increasingly volatile and global. Agility is achieved when a company can effectively respond and adapt to competitor disruptions and demand changes throughout the supply chain to meet customer needs.
Rapid economic and technological development requires increased flexibility in both internal (marketing and manufacturing) and external (supply and distribution) supply chains. Companies with flexible supply chains can be more resilient in uncertain situations. Respond quickly and provide the company with the ability to demonstrate products and services quickly and effectively.
In a globalized world, competition has spread to the entire supply chain, not just companies. Therefore, supply chain members need to reorganize themselves to balance the organization's ability to respond to market changes by increasing flexibility.
In today's economic environment, companies outsource some business processes to ensure supply chain flexibility, which often results in a loss of control and visibility of various logistics operations. Thanks to digital technologies, integrated transport and logistics systemsVisibility will be achieved at all stages of delivery of goods from manufacturer to end user. Companies need to share information directly so it can be quickly applied to every company in the supply chain, thereby increasing supply chain agility.
So this requires different information to ensure that the chain can function as a whole. Therefore, information transferred from one organ to another should be helpful and available elsewhere in the chain.
Blockchain technology serves customers by facilitating tracking and tracing of orders from various stages of production to delivery and quick adjustments. The applications brought about by blockchain technology can only be implemented at specific touch points in the network if accepted by the relevant parties, thus controlling the data security of all supply chain transactions.
Blockchain can increase supply chain visibility and enable real-time data sharing over the network. Therefore, blockchain can support supply chain flexibility strategies by reducing the number of stakeholders affected by disruptions.
At the same time, blockchain can also quickly integrate all on-chain processes to improve forecasting and management of demand, thereby achieving more realistic supply and inventory management.
Blockchain technology has become one of the most common concepts today. As digitization becomes a common phenomenon, we have begun to digitize our assets.
Blockchain can serve as an effective tool to build trust in the supply chain by increasing transparency and flexibility in the supply chain. However, Maoqiu Technology also believes that the real implementation of blockchain in supply chain applications cannot be separated from mutual trust between enterprises. Only in this way can an effective consensus foundation be formed, mutual collaboration capabilities can be improved, and the operating efficiency of the supply chain can be improved.
