This topic comes from the practical application of a domestic chemical company. As one of the earlier established chemical companies in China, the company has long followed the management model under the old system in management and operation. In the process of enterprise management informationization, it lacks effective planning and unified demand analysis, resulting in Purchasing, production, sales and warehousing departments operate independently, information resources cannot be shared, department coordination is inefficient, and daily production costs are increased. Facing the increasingly competitive market economy environment, the enterprise has an urgent need for an effective inventory management system.
1.1.2 Research Significance
In view of the scale and operating status of the chemical enterprise, this design draws on the advanced concepts of domestic and foreign invoicing management systems to scientifically formulate production plans and form a rapid response mechanism for production and invoicing systems. On the basis of unified data, standardize raw material procurement, product production, sales and warehouse management, realize closed-loop management of purchase, sales and inventory information, track quality information in real time and effectively, quickly respond to various problems that arise, strengthen departmental operation and collaboration efficiency, reduce Waste of resources and reduce management costs, thereby enhancing the market competitiveness of enterprises, increasing market trust and market share of products, and bringing more benefits to enterprises and society. In order to improve the efficiency of sales and procurement business processes, shorten the management cycle of sales and procurement, optimize management processes, reduce operating costs, improve customer service, and increase customer satisfaction. Integrated management of customer, supplier business, and capital transactions, efficient decision-making of corporate business information, and enhanced market competitiveness.
1.2 Current status and comparative analysis of related technology research at home and abroad
1.2.1 Domestic research status
The chemical industry occupies an important position in China's economic and social composition. The industrial added value, sales revenue, and total profit and tax created by the chemical industry are all in the forefront of industrial enterprises in the country. However, due to some reasons, the information management of chemical companies is slower than that of other industries, and it is basically still in its infancy. Judging from the current situation, although some chemical companies have started the construction of information management, they mainly focus on financial computerization, product computer-aided design, and automatic control of production processes. There are fewer enterprises that fully realize the informatization of enterprise operation and management, and even fewer enterprises can share resource information with the outside world through the information management system.
The reason why the informatization construction of chemical enterprises is relatively slow is inseparable from the characteristics of the industry itself. Factors such as a wide variety of products in the chemical industry, complex production management processes, raw material costs, and use standard control are all things that need to be considered in the information management of chemical enterprises [1] o In addition, China's chemical industry also has some other characteristics, such
as High energy consumption, large amount of waste, relatively backward technology, rapid technological innovation, and great development potential. Due to the relatively large production capacity and output base of the chemical industry, the relative production cost is relatively low, and it has good market potential and localization advantages. But at the same time, there are also difficulties such as relatively backward production technology, small scale, geographical dispersion, insufficient financial strength, weak scientific research and innovation capabilities, and imperfect marketing network.
With my country's accession to WTO and participation in international economic operations, the development of economic globalization has challenged the development of small and medium-sized enterprises in my country. Today, with the increasing popularity of informatization construction and management, the original manual management and simple stand-alone management can no longer meet the needs of informatization management construction. Lacking an information management system, it is difficult for the warehousing and freight department to efficiently extract important parts from a large amount of information, and it is difficult to make effective decisions based on the extracted information⑵. The company's management personnel can only conduct decision-making management based on the report data, and cannot effectively supervise the business process of purchase, sale and storage in real time, and it is also difficult to ensure the accuracy and timeliness of the data. Therefore, enterprises in my country's chemical industry urgently need to construct an invoicing management system that meets their own characteristics. The system not only needs to cover advanced management ideas that meet the needs of the enterprise itself, but also provides integrated decision-making and management tools to assist enterprises to achieve business objectives and improve management levels.
1.2.2 Research Status Abroad
Foreign invoicing software developers started earlier. Representative manufacturers of such software include SAP, ORACLE, and PEOPELSOFT (currently acquired by ORACLE), among which more than 80% of Fortune 500 companies are benefiting from SAP's personnel management solutions. The common features of this kind of software provided by these manufacturers are friendly interface and strong operability. They adopt a variety of mainstream database platform technologies such as Oracle and SQL Server, have rich implementation experience and tens of thousands of business process models[3]o this The class system can also run on large-scale mainframe operating systems such as Unix and AS/400, and has good openness and flexibility. However, due to the price factor, many small and medium-sized enterprises are discouraged from it, and it often becomes a factor limiting their market share.
At present, domestic companies producing such software mainly include Youyou, Kingdee, Neusoft, and Chinasoft. However, due to the relatively late start of computer software technology in my country, it is still difficult for domestic manufacturers to compare their software products with those of foreign manufacturers, especially in terms of software implementation experience. Most of the current domestic products are based on SQL database and Windows operating system, which cannot fully support other network technology platforms. This type of software information system can only be applied to small-scale enterprises with relatively simple business logic. When the number of employees and the business process of the company are complex to a certain scale, this type of software information system is difficult to meet the needs of the enterprise, slow data processing, a sharp drop in reading speed, frequent system crashes and other problems become difficult problems in the application of this type of system [4].
At present, the application of the purchase, sales and inventory management information system in my country's chemical enterprises is still in its infancy, and most enterprises are still at the primary application level of establishing internal information networks and office automation systems. Few chemical companies have truly realized information-based enterprise management, and even fewer companies are able to share external information resources, develop e-commerce business, and benefit from information-based management. The informatization process of enterprise purchase, sales and inventory management in the chemical industry is generally not high, and there are problems such as scattered information resources, which make the existing information systems and self-owned information resources of enterprises not fully utilized, which seriously affects the efficiency of enterprise purchase, sales and inventory management.
From the perspective of software architecture, enterprise information system architecture generally includes two forms: function-oriented architecture and process-oriented architecture. Enterprise information systems in these two architectural forms are generally complex systems with multiple stages and cross-functions. In the process of this kind of system development, it is usually carried out in the form of multi-platform, multi-development tools, and multi-management norms. These factors affect the agility and stability of the system, and indirectly affect the decision-making and core competitiveness of the enterprise. play. In order to cope with the rapid changes in market demand, enterprises are required to be able to respond quickly in a short period of time, which also requires that the information management system of enterprises must have functions such as agile services, rapid reconstruction, resource reuse, and free expansion. Most of the existing enterprise information management system solutions are based on technologies such as CORBA or DCOM. Due to the limitations of the technology platform, there are some unsatisfactory aspects in the application of enterprise information systems. For example, the existing enterprise system architecture is often not After the service-oriented architecture is formulated, it is difficult to change, and it is difficult to quickly respond to changes in customer service requirements. The existing enterprise system architecture basically adopts a tightly coupled structure, and the links between systems must follow the same API agreement, making it difficult to make changes, which greatly restricts the realization of enterprise agile services and free expansion. At the same time, because the technical standards of some existing information systems are subject to the constraints and control of individual manufacturers, the application of related technologies has not reached the level of open standards. Therefore, in the face of new business management challenges, enterprises adopting information management systems should change the layout of information management systems as a whole, apply open technical standards, and comprehensively establish a service-oriented enterprise system architecture (Service Oriented Architecture, SOA) [6 ].
At present, the first-line manufacturers in the research and development of the inventory resource management system are all European and American countries. Companies such as Oracle and SAP have many years of research and development experience, a strong scientific research team, and a high market share. SAP invoicing management software has been used by more than 7,800 companies to build an invoicing management system platform, with more than 32 million employees managed. SAP
It can be based on C/S, B/S architecture, or a mixed architecture of C/S and B/S, and has complete and mature purchase, sale and inventory resource management functions. The invoicing management system solution developed by Oracle has more than 14,000 customers in 140 countries and more than 40 million employees. The invoicing system developed uses the Java language and Oracle database, based on the B/S architecture, and also has a complete set of invoicing resource management functions.
1.2.3 Comparative analysis
The local Chinese companies that develop the resource management system for purchase, sales and inventory are far from comparable in terms of experience and R&D strength due to their late start. However, after more than ten years of development, there are still a number of software companies that stand out and have a certain share in the domestic market. At present, domestic companies that develop inventory resource management systems mainly include Neusoft, UFIDA, and Kingdee. Consider and designate a complete inventory resource management system for customers. With the increasingly fierce market competition, especially the development of global competition, my country's chemical enterprises need to use advanced supply, marketing and inventory management systems to realize information integration, process optimization and resource optimization allocation, so as to finally achieve the unified integration of logistics and information flow , Enterprise decision-making is agile and effective. Therefore, designing a suitable supply, marketing and storage system has become an important and urgent problem for this chemical enterprise.
