What is CIM (Computer Integrated Manufacturing)
Computer integrated manufacturing, CIM for short. In the past 20 years, the concept of CIM has been continuously enriched and developed. Driven by the industrial countries in the world, CIM has experienced the conceptual evolution of a hundred schools of thought and entered a period of vigorous development. In the early 1980s, the agreement between the United States and Japan on CIM basically focused on the scope of manufacturing and product development. Germany began to pay attention to the theme of CIM in the early 1980s, and various concepts and definitions appeared, until 1985 (federal) AWFA put forward the recommended definition of CIM, which achieved a certain degree of unification.
Edit this paragraph, and its recommendation is defined as
CIM refers to the integrated use of electronic data processing in all production-related enterprise departments. CIM includes the collaborative work in information technology among production planning and control, computer-aided design, computer-aided process planning, computer-aided manufacturing and computer-aided quality management, in which various technical functions and management functions necessary for producing products should be integrated. 1990 IBM defines CIM as the application of information technology to improve the productivity and responsiveness of an organization. The Japanese Energy Association put forward the definition of CIM in 199 1: In order to realize the business strategy of enterprises adapting to the future enterprise environment, it is necessary to optimize the combination of development, production, logistics and services from the sales market. CIM is a new production system, which takes information as the medium, integrates enterprise activities with various business fields and their functions through computers, and pursues overall efficiency. Recently, the European CIM-OSA Project Committee (265,438+0 European automation companies and research institutions, including the European branches of IBM, DEC and HP) summarized the basic points of CIM definition in the above countries. First, all production links in the industry are inseparable and need to be considered in a unified way. Second, the whole manufacturing process is essentially a process of information collection, transmission and processing. Its definition of CIM is: "CIM is a comprehensive application of information technology and production litigation, and its purpose is to improve the productivity and responsiveness of manufacturing enterprises, so that all functions, information and organizational management of enterprises are all parts of an integrated whole." After more than seven years of CIM practice in the 863 project, China thinks that CIM is a new philosophy of organizing, managing and running enterprise production. It helps computer hardware and software to integrate the three elements of people, technology and management in the whole process of enterprise production, and organically integrate and optimize the operation of information flow and logistics. In order to achieve high quality products, fast listing, low cost and good service (T.Q.C.S is the abbreviation of time, quality, cost and service respectively), enterprises can win market competition. "
Please edit this paragraph for details.
The above definition can be further elaborated as the following five points: 1. CIM is a philosophy of organizing, managing and managing the production of enterprises. Its purpose is to make the products of enterprises have high quality, quick listing, low cost and good service, so as to win the competition. 2. All aspects of enterprise production, namely, market analysis, business decision-making, management, product design, process planning, manufacturing, sales and after-sales service, are an inseparable organic whole, and should be coordinated from a systematic perspective, so as to achieve global optimization. 3. The factors of enterprise production include people, technology and management. Among them, we should pay special attention to the leading role of people in modern enterprise production. 4. The production activities of enterprises include information flow (collection, transmission and processing) and logistics. Modern enterprises should pay special attention to the management and operation of information flow and the integration of information flow and logistics. 5.CIM technology is a comprehensive technology based on modern management technology, manufacturing technology, information technology, automation technology and system engineering technology. Specifically, it integrates and develops computer-aided technologies related to all aspects of enterprise production, including computer-aided management and decision-making, computer-aided modeling, simulation, realization and computer-aided quality management and control.
Editing this paragraph of CIM is a philosophy and guiding ideology.
CIM is a philosophy and the guiding ideology for organizing modern production. CIMS (Computer Integrated Manufacturing System)-Computer Integrated Manufacturing System is the realization of this concept. CIMS can be defined as a complex system that realizes system integration and optimization through computer hardware and software, and comprehensively applies modern management technology, manufacturing technology, information technology and automation technology. Different types of enterprises, such as single-piece production enterprises and multi-variety, small and medium-sized batch production enterprises or large-scale production enterprises, have different types of production and operation identification; Discrete manufacturing industry and process industry have different business objectives, different enterprise basic conditions and different original computer resources, so their implementation schemes, processes and results will be different. Therefore, we say that different types of enterprises, different products, different batches of production, different production technologies, different automation foundations, different management systems and different management strategies will have differences in CIMS scale, composition, implementation mode and operation mode. In recent years, the international research and practice of CIMS has been further developed, and some new concepts have been put forward, such as concurrent engineering, lean production and agile manufacturing.
Edit this concurrent project
1987 the definition of concurrent engineering put forward by the national defense analysis institute of the United States is: "concurrent engineering is a systematic working mode of parallel and integrated design of product design and its related processes (including manufacturing process and supporting process). This working mode tries to make developers consider all factors of the whole product life cycle from the beginning, including quality, cost, schedule and user needs. " This shows that the purpose of the Chief Executive and CIMS is the same. Both of them win the competition by accelerating the development cycle of new products, improving product quality, reducing costs and providing quality services, that is, T.Q.C.S CIMS focuses on information integration and information sharing, that is, by integrating the automation system formed in enterprises with styles and databases, the unified formulation and operation of production plans from south to bottom can be realized. The organizational structure and management of the production process are basically traditional, and all departments and links are basically independent in order during the operation. On the basis of CIMS information integration, managers can understand the whole process and realize effective monitoring, so some achievements have been made in T. Q.C.S. However, with the fierce competition, resources (technology, people and facilities) have been continuously tapped, and the start-up time has been shortened as much as possible. Therefore, it is necessary to decompose, analyze, optimize the design and integrate all stages in the product life cycle, and organize multidisciplinary development teams to be responsible for the development of the whole product according to the scale, scope and treatment methods of the product, so as to reduce "repeated changes" in the development process. This kind of development process needs the coordination work within the development team and the parallel process interaction.
Edit the interoperable CE support environment in this section.
In order to adapt to multidisciplinary collaboration, it is necessary to establish an environment, which puts forward higher requirements for integration, that is, to establish an interoperable CE supporting environment, including information exchange platform and data exchange standards, and this environment is carried out in parallel. In order to adapt to multidisciplinary collaboration, an environment must be established, which puts forward higher requirements for integration, that is, an internally interoperable work and environment must be established, which puts forward higher requirements for integration, that is, an internally interoperable CE supporting environment, including information exchange platform and data exchange standard, supports the whole process of product development in parallel. This makes CIMS from information integration to function integration and optimization, which will also involve people and organizational systems.
Edit this paragraph "The Machine that Changed the World"
1985 The Massachusetts Institute of Technology (MIT) established a specialized agency for the International Automobile Program (IMVP). After five years of comprehensive and in-depth research on the automobile industry in the United States, Japan and some European countries, 1990 wrote the book "The Machine that Changed the World". The authors of this book, James Womach, daniel jones and Daniel Ruth, summarized the successful experience of Japanese manufacturing industry for decades, and put forward for the first time that every worker in the production manager has the right to stop production in a work area when there is a production failure, so as to eliminate the failure. All employees in the enterprise are lifelong employees of the enterprise; Employees are versatile, and all departments of the company cooperate closely. The second feature of refined production mode is to eliminate the work that will not produce value in production through "simplification". It is demand-driven and simplifies the process of production and product development. At the beginning of product development, designers, technicians and engineers are formed into a project team, and a large amount of information can be processed in the team, which simplifies the transmission of information, makes the system response very flexible, and reduces the time and resources of product development. It also simplifies the organization, reduces non-production costs, and eliminates indirect work and intermediate management such as repairmen, cleaners, inspectors and parts inventory managers, thus reducing the backlog of funds and a large number of non-production costs. Excellent production is continuous improvement, with "perfection" as the ultimate goal. Its core is streamlining, streamlining all the links that do not produce added value in the process of product development, design and production management. It is the multi-faceted management that solves the problem of T.Q.C.S from the perspective of management, so as to win the competition.
Edit this public information model.
CIM, Common Information Model (CIM) is a conceptual model that has nothing to do with concrete implementation and is used to describe management information. CIM is divided into two parts: CIM specification and CIM mode. CIM specification provides a formal definition of model, which describes language, naming, metamodel and mapping technology to other management models (such as SNMP MIB). The CIM pattern gives a description of the actual model. CIM model consists of three layers: core model, common model and extended model. The core model is a collection of a series of classes, connections and attributes. This object group provides a basic information model common to all administrative domains. The public * * * model provides a common information model for specific management domains (such as systems, applications, networks and devices). The extended model represents a specific technical extension of the general model. Through CIM modeling, we can get the abstraction and representation of entities in the management domain, including their attributes, operations and relationships. This model is independent of any specific database, application, protocol and platform. Therefore, CIM model requires that applications based on different platforms provided by different developers adopt a standard format to describe management data, so that data can be shared among various applications. CIM adopts object-oriented method to construct a new structure and conceptual model suitable for management system and network. CIM modeling is a general method. CIM modeling in specific management domain is extended on the basis of core model and common model. Generally speaking, CIM is a standard that defines a consistent model. According to this model, network devices, systems and applications can display information about themselves, which can be used by management tools to describe information such as desktop software and hardware configuration, serial number of CPU packet blocks and traffic level on specific router ports.
Edit this call information management system
Call information manager realizes the synchronization of call center voice and additional data. The system is connected with UltraLnk and monitors all IVR extensions, seat extensions, ACD queues and other equipment. It collects, analyzes and processes all kinds of telephone events and call information of monitored equipment, such as incoming call, transfer, meeting, hanging up and call information such as ANI and DNIS, and generates and maintains a unique call identification number (CALLID) in the whole call process. CIM system also tracks the occurrence of telephone events such as call forwarding and conference, and the generation of new additional data such as IVR selection, and the application program obtains or updates the additional data through CALLID. By using CIM module, users can conveniently realize important functions such as screen pop-up, synchronous transfer of voice and screen, call statistical analysis and so on.
