1 Features of logistics information under the supply chain management environment The supply chain is surrounding core companies, through the control of information flow, logistics, and capital flow, starting from purchasing raw materials, making an intermediate product and the final product, and finally sending products by sales network Consumers, suppliers, manufacturers, distributors, retailers, until the end user is connected to a whole functional network chain structure mode. Supply Chain Management is a cross-industry management of goods, information and funds in the production and circulation process, involving all aspects of various enterprises and enterprise management, and companies as trading partners, in order to pursue common economic interests Maximization and work together. The most critical supply chain management is to adopt integrated ideas and methods, and apply advanced information technology to implement their management objectives. Logistics is an important part of the supply chain, which runs through the entire supply chain. In traditional logistics systems, logistics activities are dispersed in different economic sectors, or in different functional departments within an enterprise, logistics information itself is also dispersed in different links and different functional departments, relevant logistics The operation information is mainly to communicate between the upstream and downstream links adjacent to the supply chain, and is separated from the entire supply chain. The communication and sharing between logistics and information is very slow, and it is lagging behind many management activities. In the supply chain management environment, in addition to the information exchange of the supply chain adjacent, there are sharing information across the entire supply chain, the transmission of information is no longer a chain-stricken structure, but is cross-interlaced. The mesh structure is shown in Figure 1. This makes the logistics information are no longer limited to a certain logistics link. Any nodes on the entire supply chain can see this information, keep market demand and supply chain operation, while necessary management, coordination And organize work, keep logistics on the supply chain synchronize, more precise and rapid. Compared with the traditional logistics system, logistics information in the supply chain management environment mainly has a wide information source, very strong dynamic and large amount of information, and has a variety of information. The logistics information management in the supply chain management environment is more complicated. The task of supporting the supply chain management is more difficult to carry out logistics information construction. 2 Analysis of my country's Logistics Information Construction 2.1 The achievement of logistics informationization in China my country's logistics information construction is mainly implemented by some logistics companies and some logistics departments of China, and is attached to the entire information construction of the enterprise. Looking at the development process, it mainly achieves the following achievements: First, the importance of enterprises has further improved the level of information construction, and considerable part of the organization has been prepared for information construction, planning, investment budget, personnel training and other preparations. . Second, the level of construction of information infrastructure is improved, and the information application environment improvement is improved. The computer ownership rate and net network of enterprises have improved, and the coverage and business applications of various networks are also increased. Third, the construction and application of various information systems have brought positive changes and obvious benefits to enterprises. The survey shows that by informationization can reduce costs, reduce production cycle and work hours, and expand product sales revenue, improve flow capital turnover Rate, improve the delivery capacity of delivery, and thereby bringing direct economic benefits to enterprises. 2.2 Problems in my country's logistics information integration
At present, my country's logistics information system construction and application overall levels are still not high, and the system integration and resource sharing are low. This issue has become a bottleneck that restricts the advanced ideological application of supply chain management. Specific performance in the following: 2.2.1 Logistics information The demand for system integration is not clear. Although from the current trend of current logistics informationization development, the objective information system has an internal networking, up and down, external horizontal coupling, and some companies have subjective realized system integration is the next logistics. The focus of information construction, but most of the contents of the integrated integration, the resources are unclear, and the deep reason is that most logistics companies are carrying out information construction on the basis of their own traditional advantage. Some systems are used. Advanced information technology simulates existing manual operations, lacks essential understanding and re-planning of the entire logistics business process in the supply chain management environment, thereby doing not know where the integration of the logistics information system. 2.2.2 Construction of the logistics information system lacks guidance from integration methods. According to the statistics of China, the application of my country's logistics information system is at the operating level of basic logistics, such as bar code management, GPS, GIS, three-dimensional libraries, call center, etc., is just a part of logistics enterprises and corporate related departments, showing The situation of zero and dispersed, lacks integration of logistics information management systems. Due to the lack of system integration ideas, these systems often lack overall planning, overall design and process control at the beginning of construction, and different systems or modules are provided, isolated and implemented by different manufacturers, leading to most applications. " Island "state, single application, department-level applications, very small enterprise integration applications, and more integration of supply chain. 2.2.3 Soft environment construction of logistics information systems is relatively lag. Although the industry and enterprises have some planning of relevant logistics informationization, some technical systems, standards, etc., but the norms and standards are not perfect, if some specification or standard is operative, it is difficult to implement, and some The logistics information standards between different industries have not formed unified, resulting in information exchange faults, and has also formed a waste of resources investment in my country's logistics information technology. In addition, the logistics information system integration lack of effective management coordination mechanism for the supply chain of only a benefit relationship, the macro is difficult to regulate, and the direct consequence is the construction of "chimney" forestry, data is not compatible, and the format is not uniform. The resources are not shared, and the information is not interoperable. 2.2.4 The lack of composite talents in the integrated construction of logistics information systems. The integration and construction of the logistics information system in the supply chain management environment is a complex, huge social system project, which requires a large number of specialized talents to focus on theoretical research and practice, especially the top design needs to be both information technology and systems. Development has a comprehensive understanding, and has known advanced composite talents of the entire logistics supply chain operation and management, but the scarcity of such talents has largely restrict the development of logistics information system integration and construction. The above problems show that my country's logistics informationization is far from reaching the level of supporting supply chain management, especially the integration of logistics information systems restricts the improvement of logistics capacity in the supply chain management. 3 The integration of the architecture information system of the integrated logistics information system based on supply chain management is not a simple superposition of personnel, products and equipment, nor is it a matter of life. In fact, an application problem integrates a number of applications to be integrated with a number of applications. It is difficult to keep the changes at any time, and the system dynamic integration is appropriately supported. Therefore, in this sense, the integration problem of the information system is the construction of the integrated information system.
From the current situation and development trend of logistics informational construction, it should be analyzed from the supply chain management integrated logistics, whether it is integrated with existing application systems, or new logistics information systems, and analyzes the construction of integrated logistics information systems. Structure, thereby supports dynamic integration of logistics information systems. In the supply chain management environment, the architecture of the integrated logistics information system can be represented by a three-dimensional model. The first dimension is divided from the logistics management level in the supply chain, from bottom to four levels: business operating layer, operation management, strategic management, supply chain management. The business operation layer is mainly automated control of the collection and operation of some logistics information; the operation management is mainly some transaction system and office automation system; the strategic management system is mainly some comprehensive management information system, such as ERP, etc. Chain management is primarily supporting enterprise information flow management and sharing systems. The logistics information system in different management levels is different from the depth requirements of the information processing, but there is a need for up and down between the management layers. The second dimension is based on the functions of logistics and the fields involved, such as procurement, storage, production, sales, transportation, etc. These are all different functions and different business links in the supply chain. The logistics runs through these links, and its information support system is mainly related to the information and functionality of the processing, such as a warehouse management system, customer relationship management system, vehicle Management system, etc. There are logistics information exchange and sharing between these different business sectors and links. The third dimension is divided according to the different contents included in the information system itself, four levels: hardware, software, information, application. These are platforms that make up the basic elements, hardware and software constitute the application of the information system, and the information is the most important resource of the application. The effect of the logistics information system application is ultimately rely on people - machine - technology - management. The analysis found that between the three dimensions of the above models, the links between each block are complex, the integration needs are also diverse, but we can build a support chain with the architectural framework of the integrated logistics information system constructed. Manage logistics information system. 4 Logistics Information System Integration Strategy Based on Supply Chain Management From my country's logistics management and information construction, it is necessary to make the logistics information system a powerful tool for supply chain management. The following strategies should be adopted to promote logistics information systems. Integration: 4.1 To redesign the logistics process of the supply chain is a new management model integrating enterprise core competitiveness. In this mode, the concept of corporate resources is extended, more inclined to external The reasonable utilization of resources, and enhances initiative and responsiveness. Therefore, based on the supply chain management logistics information system integration cannot be simply simply connected to a computer that uses a computer to simulate the traditional manual business process using a large number of interfaces. Only the logistics process of each company in the supply chain is first analyzed. According to the re-design of the supply chain management concept, the information system integration can be established in advanced management mode; on the other hand, the supply chain management logistics integration process is based on information, the enterprise logistics process The recombinant and integrated logistics information system applications are ultimately realized, so the integration of the logistics information system is also the process of reorganizing the logistics process. 4.2 To pay attention to the application of integrated information system development methodology, the development methodology of integrated information system is the model, language, method, tool and other technical factors, language, methods, tools such as integrated information system, and the development team and technical personnel, business environment and final User quality, investment intensity and distribution, development leadership and organization management and other social elements, as well as the cognitive system composed of its doors, which are both philosophical and practical. The study of methodology puts the main energy to develop universal public methods and procedures, with a unified approach, and then design the specific system of different uses, which is convenient for integrated integration and interoperability.
