0 preface

informatization, as a powerful measure to improve the product R & D speed, quality and service level of enterprises and reduce the R & D, manufacturing and operation costs of enterprises, has been widely recognized by academia and industry, and has been widely and deeply applied in various fields. However, in view of various reasons, many enterprises are facing different and the same problems: that is, each business field has an automated information processing system, but there are different degrees of difficulties in information exchange between different businesses or fields, which has become a serious obstacle to the further improvement of the overall level of the enterprise. Therefore, it is of urgent application significance to explore the information integration methods that connect the automation of various isolated islands faced by many enterprises

1 problem analysis

in order to solve the information integration between islands, we must analyze the causes of information islands to lay a foundation for specific analysis of specific situations

the so-called information island is an information processing system for a business field of an enterprise supported by certain software and hardware. The characteristics of isolated island are mainly manifested in internal coordination and external conflict. This paper analyzes the causes of information island according to the bucket effect and bottleneck theory in management. According to the bucket effect, when the information island was founded, it was faced with business areas that the enterprise urgently needed to straighten out and business problems that urgently needed to be solved. Therefore, priority was given to the creation of information processing systems in this business area. In terms of bottleneck theory, the information system solves the processing problem of the corresponding business field. Naturally, the business field is in a bottleneck position compared with the urgent needs of the enterprise for improvement. Similarly, referring to the bottleneck theory, the solution of the bottleneck naturally causes the transfer of the bottleneck, which makes the processing in different business areas have differences between long and short blocks similar to the "bucket effect" in terms of speed and quality. Although according to the 80/20 principle, it has always been an economic and effective idea to give priority to the construction and resolving the bottleneck of enterprise operation. However, at present, in the bottleneck construction after the transfer, there is a problem that the compatibility or coupling between business and business, software and software, hardware and hardware and their cross is not smooth enough, which makes the original information system become an isolated island and difficult to realize the communication or integration with other business systems. Although the separate information system reflects the step-by-step implementation, the emergence of isolated islands finally exposes the lack of unified planning

therefore, for an enterprise that has not yet implemented informatization, the phenomenon of informatization island can be effectively solved in the process of unified planning. However, the dynamic nature of enterprise development will inevitably expose some new contradictions. Therefore, the so-called unified planning needs to be constantly revised. The so-called unified planning is for coordination among multiple business areas, and different business areas are supported by their corresponding software and hardware systems. In order to achieve smooth communication with each other, trade-offs must be made to achieve the overall effect of operation. It can be seen that the unified planning is only to advance the interconnection and interworking between different information systems to make a strong matching scheme of software and hardware systems. However, in reality, due to the lack of unified planning or correction, we must face the information integration between different systems. In a word, for non single system enterprises, information integration must be considered

2 connotation of information integration

the existence of any system is not isolated. It has its own context application environment. There is neither passive water nor targeted. Each system must have a complex relationship. The connection relationship and content between various systems are closely related to the business of the enterprise, so the so-called information integration is the technical core to realize business integration. Similarly, information integration involves a series of data exchange control issues. Therefore, on the whole, the context of information integration is business integration and data integration, and plays a connecting role

information integration is a process that aims at business integration and involves data exchange between different software and hardware systems. As we all know, for the integration of n information systems, if the interconnection and interworking are realized through direct interfaces, considering the problem of input and output interfaces, 2n+1 special interfaces are required at most. However, if the intermediate bridging processing mode is adopted, it is only necessary to establish the input and output interfaces between each information system and the intermediate processing system, that is, a total of 2*n interfaces can be developed to meet the requirements. There are two problems in choosing the direct interface or the indirect interface for the product achievement press conference held by the Industrial Technology Research Institute of China (Mianyang) science and Technology City: first, the operation of the underlying data structure between systems is not disclosed due to the technical confidentiality and other factors of software manufacturers, resulting in integration obstacles; Second, the efficiency of the indirect interface. For the first problem, due to the differences between the businesses and their processing requirements, no information system can fully cover all the business requirements of the enterprise. Therefore, there must be integration between heterogeneous information systems. At the same time, due to the complexity of the application, there will be the complexity of combination explosion in the combined application of the system, which is difficult to achieve the requirements through "point-to-point" direct integration. Therefore, the integration must be realized through indirect middleware, but for enterprises, there may be efficiency problems revealed by the second problem. Layered and distributed application through middleware, such as in Net, J2EE and other architectures have become the preferred technology to deal with complex and changing applications. With the improvement of processing speed and the development of execution optimization technology, this form of application can fully meet the enterprise's consideration of system efficiency

to sum up, considering the connotation of information integration within the business, information and data correlation system, it is a feasible solution to use the intermediate processing system to realize information integration through indirect connection, which is not only conducive to the unified planning of enterprise informatization, but also conducive to the product development positioning of software manufacturers

3 information integration methods

the nature of an enterprise determines the content of information, such as manufacturing enterprises that focus on products and operating enterprises that focus on business. However, if the tangible or intangible products are not distinguished, they can be regarded as business oriented information integration. Therefore, there are two main forms of information integration: one is the business organization with the product object as the core; The second is the organizational form based on core business. The former is a business organization suitable for manufacturing enterprises, while the latter is mainly for operating enterprises. The above organizational form is also consistent with the idea of giving priority to solving key problems. It is an organization based on bottleneck problems. The following will systematically discuss the information integration methods for manufacturing enterprises. However, since manufacturing enterprises also have their own businesses, the information integration with product object as the core also reflects the business processing mode

for manufacturing enterprises, it is the core of their operation to produce products that meet the needs of users with the best t, C, Q and s. Just as CRM, which has sprung up in recent years, attaches importance to customers and manages user needs from the source, product-oriented information integration also captures the core and essence of operation. Taking the popular product life cycle management as the main line to realize the coupling of corresponding businesses is an analysis idea suitable for manufacturing enterprises. In reality, in order to improve their own competitiveness, the original independent enterprises have gradually embarked on the idea of group operation through merger and reorganization, with unified design, procurement, manufacturing, marketing, service and other departments, which fully conforms to the concept of product life cycle management

product life cycle is not a new concept. It is mainly due to the intense competition in the market, which leads to attention to the market and services, and then forms the current concept through expansion on the basis of attention to other stages. At the same time, the product life cycle also absorbs advanced ideas such as DFX (Design for x) in concurrent engineering and XTO (x to order) in mass customization. However, compared with various advanced manufacturing concepts, especially with the support of various software vendors, PLM undoubtedly has stronger operability, which has attracted more attention in the enterprise application field

each stage of product life cycle and its combination provide a new reference dimension for enterprise information system, reflecting an inclusive framework or architecture, such as customer relationship management (CRM) for market stage, product data/development management (PDM) for R & D stage, CAPP for process stage, MRPII for manufacturing stage, SCM for purchase and delivery stage, etc. ERP takes manufacturing as the core, integrates SCM, CRM and the coordination of various resources, such as human resources and finance, to support the business activities of enterprises. In fact, ERP is a combination framework for some stages of the product life cycle, which can be regarded as a solution under the PLM architecture. Therefore, strictly speaking, for the specific problems that enterprises need to solve, the application software of a certain link can be used to solve them, or the targeted stage combination can form a selection scheme to realize the business integration based on information exchange

information integration reflects a framework. The so-called integration framework is a collection of tools that define and manage the interaction rules between multiple business systems. The framework does not replace the inherent business systems, such as PDM, mrpii/erp, SCM and CRM, but organically links the independent business systems through rules to achieve the overall good operation of the system, so as to support the enterprise's benefits and development goals. In a word, the main connotation of integration is to integrate various coupling relationships and resolve the communication barriers between business systems. Therefore, the integration framework can be understood as the collection of a series of functions such as the establishment, management and maintenance of operating rules between modules or business systems in the system

enterprises have macro distinctions such as industry, scale and nature, but the goals that enterprises must create benefits are the same. Therefore, enterprises must strive to form their own core competitive advantages to achieve their goals, which determines that no two enterprises have exactly the same conditions and implementation goals. Correspondingly, an important part of the implementation of PLM as an information system is practical and realistic customization. However, this kind of customization is not "tailor-made" to keep the current situation of the enterprise, but to realize the customization of scientific management based on process reengineering. The stage division of product life cycle provides sufficient support for PLM customization space and customization convenience: for customization space, the combination of different stages provides rich customization space and customization schemes according to the actual situation of the enterprise; For the convenience of customization, various mature business systems under the loosely coupled integration framework provided by PLM based on PDM provide certain convenience

to sum up, take PLM thought as the guidance and enterprise goal as the guidance,
