Decision-making support system belongs to

1, belongs to the strategic layer information system. The decision-making support system is a system developed on the basis of the management information system, which deepens the application concept of management information system, and belongs to the strategic layer information system.

2. Management information system is a general concept.Decision support system, manager information system and enterprise resource planning system all belong to the concept of management information system.

3. Decision support system (dss) is a computer application system that assists decision-makers in making semi-structured or unstructured decisions through human-computer interaction through data, models and knowledge. It is an advanced information management system resulting from the development of the management information system (mis) to a higher level.

What does dss mean?

1. The Chinese meaning of dss is: decision support system. DSS serves organizational management, operations and planning management (usually middle and senior management) and helps people make decisions on problems that may change rapidly and are not easy to predict results.The decision-making support system can be fully computerized, human-driven or a combination of both.

2. Olympic Mathematics DSS (DSSOlympiad, DSS-CAD) refers to Olympic mathematics, which is a mathematics education activity that cultivates students' mathematical ability and problem-solving skills. Olympic Mathematics DSS is a learning and competition platform based on Olympic mathematics.

3. What does it mean to send DSS between men and women? DSS is "implied photo and video sharing", which refers to men and women sharing sexy photos and videos with each other and stimulating each other. Although this kind of behavior is common in modern society, it is an illegal act, especially DSS without the consent of the other party.

Briefly describe the application of decision support system in modern organizations.

1. Decision Support System (DSS) is a decision-oriented information system whose function is to assist or support people's decision-making.

2. In addition, it also includes application systems for processing transactions such as analysis, statistics and query of various data, such as monthly, quarterly and annual macroeconomic monitoring systems and early warning analysis systems; macroeconomic tracking, forecasting, early warning systems, etc.

3. Fourth, the construction of the councilor's e-government system is conducive to promoting the digitalization, intelligence and modernization of the councilor's office.

4. The decision-making problems mainly solved by the decision support system: semi-structured and unstructured decision-making. Semi-structured decision-making refers to the decision-making scheme that can be generated by appropriate algorithms, so that the decision-making scheme can get a better solution.

5. The platform can support free customization of information columns, release of information, real-time or scrolling display of news, notices and announcements, electronic journals, systems, briefings, public information, etc. After release, it will be displayed in real time on the government portal and personal workbench, so that users can quickly obtain the latest information.

What are the general characteristics of the decision support system

1 and 4 emphasize the flexibility and adaptability to changes in user decision-making methods. 5 Support but not make decisions instead of high-level decision-makers.

2. Should the decision support system have the following characteristics? ( 1) Assist decision-makers to solve semi-structured or unstructured problems. DSS only plays a role in auxiliary decision-making. DSS should not replace the judgment of managers, but should put managers in an active position. ( 2) Allow users to explore several different decision-making schemes.

3. Features and composition The composition of the decision support system consists of model library and its management system, interactive computer hardware and software, database and its management system, graphics and its advanced display device, and user-friendly modeling language.Users enter the description and requirements of the problem into the decision-making support system through the interactive language system.

4. The decision support system emphasizes the support for management decision-making, not the automation of decision-making. The decision-making it supports can be at any management level, such as strategic, tactical or executive-level decision-making. The decision-making support system is a system that deepens the application concept of management information system and develops on the basis of management information system.

5. Briefly describe the characteristics of the decision support system. The decision support system comes from the discoverer of data value. For the business layer, management, decision-making level and public layer. Provide them with relevant analysis results and decision-making basis, and realize the virtuous cycle of data management and application through scientific methods and advanced tools.

6. AdoptThe effective form of human-computer dialogue solves problems, makes full use of human rich experience, the characteristics of high-speed processing and large storage capacity of computers, and each takes advantage of its strengths, which is conducive to solving problems.

What parts does the education decision-making support system consist of? Education

1, [Answer]: Since the emergence of the decision-making support system for more than 20 years, its basic structure mainly includes two-libary structure, three-livery structure, four-livery structure and knowledge-based system structure. ( 1) Two library structures.

2. The basic structure of the decision-making support system and the functions of each component 1) Database subsystem: the storage, retrieval, processing and maintenance of data, and can collect data from various information resources from multiple channels.

3. The book is divided into 9 chapters, the main contents of which include: the basic concept of the decision support system, the development status, the typical structure, the decision-making method, the model and decision support, the data and decision-making support, the knowledge and decision-making support, the collaboration and group decision-making support and other key technologies, as well as the analysis, design and development tools and Application cases.

4. The decision support system consists of model library and its management system; interactive computer hardware and software; database and its management system; graphics and its advanced display device; and user-friendly modeling language. Users enter the description and requirements of the problem into the decision-making support system through the interactive language system. The interactive language system identifies and interprets this.

5. The decision support system is generally composed of an interactive language system, a problem system, a database, a model library, a method base and a knowledge base management system.In some specific decision support systems, there may be no separate knowledge base and its management system, but the model library and method library are usually necessary.
