Three main lines of manufacturing informatization towards integration and collaboration
from the functional integration emphasized in the initial stage of CIMS in the mid-1980s, the integration of design, manufacturing and management, to the business flow integration based on concurrent engineering and business reorganization in the 1990s, and even to the inter enterprise integration based on manufacturing network in the 21st century, "integration" and "collaboration" have always been the main melody of the development of manufacturing informatization. With the development of information technology and its wide application in the manufacturing field as well as the integration of the global economy, "integration" and "synergy" will remain the main theme of the development of manufacturing information technology for a long time in the future
three routes of integration and collaboration
around the improvement of the core competitiveness of enterprises, manufacturing informatization will develop towards integration and collaboration along the three main lines of product development, enterprise management and manufacturing production. In terms of product design and development, complete product definition information is generated, managed, distributed, transmitted and used across the whole enterprise and supply chain. Product information covers the whole life cycle from product concept to recycling. The management of product information effectively integrates people, processes and information, and realizes the close collaboration between multi-functional, multi department, multi discipline and multi outsourcing suppliers. The product development process has developed from the function integration based on cad/cam/capp (C3P) to the information integration based on product data management (PDM) to the comprehensive integration of people, information and processes supporting collaboration oriented to product lifecycle management (PLM)
in terms of enterprise management, in order to achieve the goal of "providing the best products and services and obtaining the maximum profit" in the fierce market competition, the enterprise adopts modern management technologies such as operation and production planning from an overall perspective to realize the integrated and optimized management of information flow, logistics, capital flow, value flow and workflow process of internal production, To support the management organization of inter enterprise alliance, customer relationship management and supply chain management, effectively integrate and manage the information of human, financial, material, production, supply, marketing, industry market competition pattern, etc. within the enterprise, including suppliers, customers, dynamic alliances, so as to realize the high optimization of the whole business process of the enterprise. Enterprise resource management (ERP) from enterprise order management, production planning to workshop level management and control, along the vertical to achieve the integrated management of people, finance and materials in the enterprise; Through supply chain management system (SCM) and customer relationship management system (CRM), the horizontal integrated management between suppliers and customers is realized. The integration, coordination and control of supply chain is developing from simple supply chain connection to multi-level integration, coordination and control based on network and supply chain technology
in terms of enterprise manufacturing, manufacturing systems have developed from multi-level manufacturing plants in the past to manufacturing execution units that respond quickly to manufacturing. The specialized and unitized manufacturing system is directly connected to its supply chain with flat units, which is prepared by hydrogel (often used to make contact lenses) and glass fiber, and participates in the cooperation between enterprises. On the one hand, the manufacturing unit integrates the software system of the workshop, including production planning, scheduling, NC machining process planning, and other hardware systems, such as machine tools, measurement and control equipment; On the other hand, use network means to form a comprehensive integration with suppliers and customers. Manufacturing unit based on Manufacturing Execution System (MES) has been developed for a long time. Through the packaging and integration of manufacturing resources, the reconfigurability, openness and fault tolerance of manufacturing unit are realized, and the optimal allocation, integration and sharing of manufacturing resources are realized in the whole society
manufacturing informatization will be characterized by integration and collaboration, and take the full life cycle management of product development, the vertical management of ERP and MES, the horizontal integration management of SCM and CRM, and the manufacturing execution unit as the development main line. The key of manufacturing informatization is to overcome the key technologies of integration and collaboration, develop the integrated platform of digital product development platform, digital manufacturing platform and digital enterprise management, and widely build, promote and apply these three key platforms of enterprise informatization within enterprises, among enterprises and in various industries
Route 1: product development platform
the product development platform covers the whole life cycle of products from conceptual design, detailed design, analysis and optimization, manufacturing, market to use, maintenance and scrap, involving all activities and processes around products, as well as the executive departments and personnel of activities, and integrates advanced design and manufacturing management concepts such as concurrent engineering, workflow management and knowledge management, With integrated product model technology, multidisciplinary integrated optimization technology, modeling and simulation technology as the technical core, it is a software suite and solution integration body composed of a series of software tools and software subsystems that supports continuous product innovation, and realizes integration and collaboration at the three levels of data, process and application
1. Data level: integrated product model
the primary task of manufacturing informatization with products as the core is to realize the digitalization of products. Digitalization of products is to describe the geometric and non geometric attributes of products through appropriate product models. Product models must be multidimensional and comprehensive, and can support all stages and departments of the product life cycle
the integrated product model describes and stores the product definition information, configuration control information, production process control information, manufacturing information, analysis and optimization information through a unified data expression form (such as step standard). It has the characteristics of complete information, consistent semantics, flexible definition, convenient operation, expression integration and independent application, and reflects the information essence of the product, The reasonable planning and design of product data and data flow from the concept and logic become the bridge of product life cycle process integration. Based on the integrated product model, the engineering database is developed, and the data is repeatedly extracted and used on the basis of data transmission, sharing and operation, which can be used as system knowledge
the product development platform supports the continuous innovation of product development by establishing unified data standards, convenient sharing mechanism, multi database integration subsystem in distributed environment, central database based on integrated product model and knowledge base based on integrating historical data and experience, so as to realize the integration of data level
2. Process level: Unified Process Management
products form the initial concept, and form the final product through design, analysis, manufacturing, assembly and testing. They need to experience a series of activities and processes that are both independent and interrelated. The management of process has developed into the management of process flow on the basis of process sequence and process chain management
the product development platform applies the idea of workflow management, takes the integrated product model as the hub of information processing, designs a consistent workflow model along the process of product materialization and molding, coordinates personnel and organizes the execution activities at each node. On the basis of collaborative division of labor, it supports distributed applications and parallel work, and provides a collaborative work environment for all product developers. The product development platform breaks through the boundary of the original enterprise and becomes a parallel product development environment that can span regions, cultures and organizations, thus realizing process oriented integration and collaboration
3. application level: hot plug of software components
at the application level, the product development platform takes CAD, cam, CAPP, CAE and other software systems as software components, and provides component integration specifications for each functional module. All products that meet the specifications can be used as a part of the platform and support hot plug of software. The integration of unit technology and unit software in each stage of product life cycle by product development platform is not a simple combination and accumulation in quantity, but an organic integration on the basis of unified standards and overall framework. These unit software systems play a role as a part of the platform, and data sharing and interaction between software systems can be carried out conveniently on the basis of integrated product model, And the collaborative interaction based on workflow to completely solve the "information island" problem that puzzles enterprises
the integration and collaboration of the product development platform at the application level is also reflected in providing an interoperable interface for the management platform and the manufacturing execution platform, and establishing a unified data source for them, so as to ensure the bottom level integration between the three platforms and lay a foundation for the construction of digital enterprises
Route 2: digital management platform
based on the extended enterprise management mode facing the supply chain, the digital management platform aims to improve the overall operation and management ability of the enterprise, and covers all aspects of enterprise logistics, production, finance, quality, transportation, distribution, service, manpower, projects, equipment and other business activities according to market demand and enterprise business objectives, Focusing on the two major topics of relationship in enterprise management (customer relationship, supplier relationship, administrative organization relationship, etc.), provide enterprises with integrated solutions from concept to technology in human, financial, material, production, supply, marketing and other aspects. Digital management realizes the integration and coordination of horizontal and vertical directions on the basis of smooth logistics, information flow, value flow and capital flow
1. Vertical integration: from thought to action
digital management platform is the mapping of enterprise management in the information space. Along the vertical direction from decision-making to implementation, digital management can be divided into three levels: enterprise level strategic decision-making level, factory level tactical level and workshop unit level implementation level. The higher the level, the greater the impact factor on the enterprise. At different levels, according to the different functions of management, it can be divided into fund management, production management, logistics management, resource management and human management, In this way, the management matrix of the enterprise can be constructed vividly
correspondingly, the digital management platform also has a function matrix. Each different management system acts as one or more nodes of the matrix. Through these nodes, the personnel, affairs, data, resources and other elements in the operation and management of the enterprise are bound. The nodes are vertically and horizontally interconnected. The capital flow, information flow and logistics are unimpeded. Knowledge and experience are transformed into the intellectual resources of the enterprise, which flow, transform and appreciate between nodes. With the support of the platform, the whole enterprise, Into the virtuous circle of continuous optimization, so as to realize the vertical integration across the enterprise management level
2. Horizontal collaboration: from suppliers to customers
the current competition between enterprises is no longer a competition between enterprises, but a competition between an enterprise's supply chain and industrial chain. In response to this trend, the United States clearly put forward the extended enterprise model in the "next generation manufacturing technology", believing that only the supply chain and industrial chain enterprises formed by integrating customers, vendors, suppliers, partners, etc. into the enterprise are most likely to win the competition and survive
on the basis of expanding the enterprise model, the digital management platform takes meeting the needs of users as the goal of system optimization and reorganization, and improves the overall competitiveness of the supply chain through the integration of organizations involved in the supply chain and the coordination of logistics, information flow and capital flow. The essence of supply chain management business is to go deep into the value-added links of suppliers and value chains, with the shortest
