Briefly describe the connection and difference between the expert system and the decision support system.

1. The principle is different, and the follow-up operation is different. The principle is different: the decision support system uses artificial intelligence technology to realize the organic combination of data and model; the expert system is to extract the knowledge of experts and organize it.

2. The relationship between decision support system (DSS) and expert system. The development of operations planning makes decision-making more scientific, so that the decision-making process uses models and data at the same time.

3. Decision support system: mainly includes two parts: data warehouse and data mining, which are used for data analysis and provide data support for decision-making. Expert system: combine the experience of experts with IT technology to provide mature solutions, such as the medical expert system.

The expert system belongs to the several information systems

System, abbreviated as DSS), expert system (a subset of artificial intelligence (AI)) and virtual office (Office Automat Ion, abbreviated as OA) five types.

Expert System: a subset of artificial intelligence (AI) Office Automation and Virtual Office (Office AutomatiOn, abbreviated as OA) The hierarchy of management can be divided into two levels: manager information system, marketing information system, manufacturing information system, financial information system, human resources information system and information resource information system.

System, abbreviated as DPS), Management Information System (MIS), Decision Support System (Decision Sustainment System, There are five types: DSS for short), expert system (a subset of artificial intelligence (AI)) and Office Automation (OA).

Which system belongs to the new expert system

1. [Answer]: D D [Analysis] The expert system is an intelligent computer program system, which contains a large amount of expert-level knowledge and experience in a certain field. It can use the knowledge and problem-solving methods of human experts to deal with problems in this field. Question. The distributed expert system is a new type of expert system.

2. Expert system, abbreviated as ES, is a computer program or information system that simulates the behavior of human experts in dealing with problems and uses knowledge and reasoning techniques to solve problems. It combines the process of professional knowledge, reasoning and decision-making system in a certain field into a computer system to solve some practical problems.

3. The "intelligent robot" expert system is a computer program system, but unlike traditional computer programs, it is a "high-performance program to solve problems in complex fields".The so-called complex field means that the knowledge in the field is complex and huge, and often has the characteristics of uncertainty and judgment (experience).

4. The expert system is an intelligent computer program system, which contains a large amount of expert-level knowledge and experience in a certain field, which can use the knowledge and problem-solving methods of human experts to deal with problems in this field.

5. Simply put, it is a kind of intelligent system, that is, the application of artificial intelligence technology to reason and judge according to the knowledge and experience in a special field provided by one or several experts, and simulate the decision-making process of human experts to solve those complex problems that require experts to solve.
