Expert System in Artificial Intelligence

Expert System

An expert system is a computer program that mimics the decision-making and actions of a person or a group of people with knowledge and experience in a certain area by utilizing artificial intelligence technologies. Typically, the goal of expert systems is to support human experts rather than to replace them.

Expert System in Artificial Intelligence

An example of artificial intelligence is the expert system, the first of which was created in 1970 and successfully applied the technology. It retrieves the information from its knowledge base to solve even the most difficult problems like an expert. Using both data and heuristics similar to those of a human expert, the system assists in making decisions regarding complex issues. It has expert knowledge of a particular subject and can solve any complex problem related to that domain, which is why it gets its name.


Expert systems compile information from experience and facts into a knowledge base and combine it with an inference engine, also known as a rules engine, which is a set of guidelines for applying the knowledge base to scenarios that the computer is given.

Applications of Expert Systems in Artificial Intelligence

A computer program that can tackle complex issues requiring a high level of human experience is called an expert system. 

There is a huge variety of uses for expert systems. It covers topics like:

  • Healthcare Identification

  • Prediction 

  • Accounting and Finance

  • Designing

  • Planning

  • Debugging

  • Scheduling

  • Manufacturing

  • Training

  • Marketing

  • Monitor and control


1. Healthcare Identification 

For various medical diagnoses, numerous kinds of medical diagnostic packages are employed. These use observable symptoms to identify the root cause of dysfunction in complicated settings.


2. Prediction

Predicting the likely outcomes of a particular scenario is another use for the expert system. 

For instance, Predicting crop damage


3. Accounting and Finance

Expert systems are used in accounting and finance to assist with tax advice, forecasting model selection, credit authorization choices, and other tasks.


4. Designing

The expert system has shown to be highly helpful in thinking out how to configure the system's component parts to satisfy the requirements. An illustration of a VLSI system 


5. Planning  

Useful in a variety of space planning and exploration applications. 

Useful for creating student curricula. 

Helpful for organizing biology, chemistry, and molecular genetics teaching experiments.


6.  Debugging

Another useful use of expert systems is debugging. It involves recommending and putting into practice fixes for problems.


7. Scheduling

The expert system helps with customer order scheduling. operating system resources on computers. Production processes. different manufacturing jobs.


8.  Manufacturing

The application of expert systems in production is successful. It is beneficial in:.

  • Determining whether a procedure is operating correctly. 
  • Evaluating the quality. 
  • Delivering remedial measures. 
  • Product layout and design.


9. Training

An expert system is a great teaching tool for students. Numerous expert systems explain the reasoning behind a specific solution, teaching the user how the system arrives at a conclusion.


10.  Marketing

 In the marketing domain, expert systems are utilized for setting sales targets. answering questions from clients. deciding on refund guidelines.


11. Monitoring and control

 An expert system can be utilized to monitor cash management, personnel actions, processors, etc. These aid in maintaining control even in the absence of the specialist. beneficial for controlling how a complex environment behaves.

Advantages and Disadvantages of Expert System in AI

Advantages of Expert System in AI

1. Increased Production and Efficiency 

Expert systems operate at a faster pace than average people.


2. Cut Down on Time Spent Making Decisions 

A human can make judgments quickly with the assistance of an expert system. It is effective for the frontline decision-maker, who frequently interacts with clients.


3. Improve Product and Process Quality 

By providing optimal guidance, the expert system lowers the quantity and frequency of errors. It contributes to higher-quality products.


4. Adaptability 

It offers flexibility to the manufacturing and service industries.


5. Reduce the amount of idle time 

Expert System reduces machine downtime by identifying problems and recommending fixes when necessary.


6. Simplified Equipment Functions 

The expert system makes it simpler to operate the complicated equipment.


7. The Acquisition of Limited Expertise 

When expertise becomes scarce, an expert system provides assistance. This happens when specialists are needed in several locations or when the expert is about to retire. It also happens when professionals are not available to present for the assignment.


8. Elimination of the Requirement for Pricey Equipment 

Expert systems use inexpensive devices to perform monitoring and control. This is possible because the expert system quickly and thoroughly analyzes the instruments' information.

Disadvantages of Expert System in AI

1. Hard 

A more accurate situational assessment is difficult to come by when there is a limited amount of time. This also extended to experts with skill.


2. Need for Skilled Engineers 

The design and development of the expert system require the expertise of expert engineers. Because engineers are hard to come by and expensive, building an expert system ends up being a pricey endeavor.


3. Specific Assignments 

The expert system performs well when used for particular kinds of analytical and operational tasks.


4. Restricted Terminology and Lexicon 

It pertains to certain domains and operates smoothly in restricted problems. Limited language is employed to convey relationships and facts.


5. Different in thinking, expensive, and reliant 

Although specialists' approaches to the assessment may differ, they are all accurate. It does not provide a means by which one could independently confirm the validity of the conclusion. The expense of upkeep is very high.
