The Research And Application On Sale Information System And Its Production Plan Of ERP

ERP system is an implement pattern of modern corporations, which integrates the information technology with the advanced ideology of management. It reflects the era when the corporations should rationalize the resource and create well-being for the society to the greatest extent. Therefore, it becomes the footstone for the corporations to survive and develop in the information ear. Now, ERP is widely implemented in discrete manufactories, financial companies, telecom enterprises, and even university and public institutes. And of course, It can be implemented in continuous process industry.There are many differences between different kinds of industries, so development and implementation of ERP has its own characteristics and keystones. Taking a large-scale paper mill as an example, several basic theories and key technologies of how to design and implement ERP and its subsystems are discussed and analyzed in this thesis.In chapter one, the concept of ERP is introduced, as well as important place of sale department in ERP system. The main function of sale system for ERP are presented. At last, the production plan system for ERP is expounded.In chapter two, OMT(Object-Oriented Modeling Technology) and DPM(Data Platform Method) that used design and development of ERP are presented. Because of its weightiness, the process of implementation of ERP is given in detail. The design and development of ERP system for paper mill is expounded, as well as the module and the specialty of the ERP system.In chapter three, taking the development and implementation of sale information system of Qingshan Paper Mill as an example, the development and the implementation of sale information system of ERP are introduced. Meanwhile, the system is analyzed and its lower functional mode is established. The concept and technology of multi-layer architecture is introduced, and the distributed multi-layer architecture of sale information system is analyzed in details.In chapter four, First, the concept and basic flow of genetic algorithm is introduced, as well as a genetic algorithm based on variable length coding . Based on the specialty of flexible processing enterprise, we designed and developed production planning system of processing ERR At last, a genetic algorithm based on variable length coding for the Scroll cutting problem in production planning system is proposed.A last chapter summarized the whole paper and presents the works need to do in future.
