The background of the next generation of ERP-Dynamic Enterprise Modeling (DEM) DEM ---- The development of manufacturing technology has brought about changes in management ideas. The earliest management idea can be traced back to the 1911 F.W.Taylor's work "Principles of Scientific Management". " In 1913, F.W. Harris proposed EOQ formula to reasonably control the stock. From the 1960s ~ 1970s, Orlicky proposed MRP. Subsequently, MRPII, including integrated financial management system, MRP, and demand management. In the 1990s, ERP proposed, including integration with various systems related to enterprises (such as HR, CAD / CAM, PDM, Finite Scheduling, and EDI, etc.). ---- After entering the 1990s, the world pattern has undergone fundamental changes. Reflected in the manufacturing industry, the globalization trend is increasingly obvious. ---- Dynamic multi-change market requires companies to have better flexibility, can adjust their business process (business process reorganization, BPR) based on changes in the environment. At the same time as business process recombination, existing information systems must also be adjusted. This will support the restructuring of the business process in different levels, so that it can actually act. However, existing ERP software (such as SAP / R3, Oracle, etc.) is poor, and it is not well to meet this requirement. The stiff information system and dynamic market, frequent BPR will become an important contradiction in the future. In order to solve this contradiction, the Netherlands BAAN proposed the next generation of ERP, namely dynamic enterpreise modelling, demary, and has put it into implementation. ---- DEM is different from the following key aspects from the usual ERP: · DEM supports continuous business process improvement; · DEM supports the restructuring of software structure; · DEM can run high quality operation; · DEM allows customers to choose their own Interfaces and work platforms and can be easily integrated with other work platforms. The purpose and characteristics of DEM - the purpose of DEM is to make users familiarity, according to their company's internal and external environment, the fastest, best to establish company business control model, business function model, and business process Model, or adjustment, saving time, eliminating waste, reducing costs, and improving efficiency, in order to survive and develop in the unpredictable sustained, rapidly changing competitive environment. ---- DEM is a revolutionary software design method, its essential feature is to create a new information system by using dynamic management models. Each model is dynamic because it allows and easy to plan and record its development and evolution history, so support continuous optimization of the business process. In DEM, it mainly reflects two ideas: First, when generating a specific model of a company, make full use of the best examples of knowledge and practical experience, and express the use of the enterprise reference model; second, in the dynamic company, the company The information system can adapt to the rapid change of the company's environment, which is manifested in DEM tool - the use of corporate modeling tools. ---- The three main advantages of DEM are: • The speed is quickly reflected in the use of enterprise modeling tools in a short, compact Orgware software, and reduces the difficulty of this process by using a predefined business model. · The software structure of flexible high DEM can change accordingly with the changes in the business process of enterprise business. The advantages of the above aspects are achieved through the full integration of enterprise modeling tools and application software, which also enables many work in the process of modeling. · Quality DEM has improved the quality of corporate modeling because it uses a simple way to make it very complicated.
DEM content ---- 1BAAN IV ORGWARE ---- DEM is a concept, a method, and Baan IV Orgware is a tool for implementing DEM, which is the key to state DEM. BAAN IV ORGWAR is composed of four parts, namely: Enterprise modeling tools make companies can use graphical description of the organizational structure, functional characteristics, and service processes of the business model. · Enterprise reference model These models are automated, electronic, project engineering, etc., providing a reference for establishing this enterprise model. · Enterprise Model Performance Management Tools This is the Orgware Performance Management Tool, including a set of predefined performance metrics for all modules of BAAN IV ORGWARE. Simply put, this is the evaluation module. · Implementation module ---- In the DEM conceptual framework, BAAN is implemented through three consecutive assignments of three predefined models, each model represents the structure of the structure, and their combination represents the entire enterprise. These three models are: ---- 1) Business Function Model ---- The first step of application DEM is to assign a value to the business function model. In a grading function tree, the business process is described as "black box", here The blackbox defines what should be done at this stage without considering how the specific is doing, the main purpose of the function model is: ---- (1) Establish a knowledge base (expert system), which is recorded "Best Example" Business Knowledge (Enterprise Reference Model). ---- (2) Guidelines for dialogue between management and consultants (information exchange). ---- (3) On the basis of relevant business analysis, the selection and modeling of the business process is started. ---- 2) Business Process Model ---- Business Process Model Specifies how to implement business functions on the BAAN function, which is modeled at the lowest level of the process, actually an example transform process. So the specific procedure can be displayed in the appropriate time and place in the appropriate time and place. The main purpose of the business process model is: ---- (1) how the business function is implemented by dividing the process. ---- (2) Use the process as an ideal tool to explain the BAAN function, but the most important thing is that BAAN can do what users do. ---- (3) The process is a starting point for generating the target user environment (end-user environment). ---- 3) Business Organization Model ---- Business Organization Model Describes the organizational structure based on division, business units and sectors, one of the key issues is identification of the role in the organization. Here, the action refers to the behavior or task assigned to a particular person or a working group in the process execution. Another feature of the model is that the level and functional relationship between different components in the model can be specified. ---- 2DEM structure and the relationship between the three models ---- 1) Dem structure diagram ---- DEM structure is roughly divided into three levels, namely: core functional layer I, process management II and organizational management level III. For different companies, although II, III are the same, I is different. ---- 2) The relationship between the three models of DEM ---- Three models in DEM are business control models, business function models, and business process models. When a reference model is used as a Project model, you must use the top downward method to study and re-evaluate the reference model, and start from the business control model because the business control model is very important to understand the entire structure of the model. of. The business control model consists of multi-layer block diagram, which represents the function and the flow between these functions.
