An expert system is an interactive computer-based decision support system that uses both facts and heuristics to solve complex problems in a specific domain. It aims to emulate the problem-solving and decision-making abilities of human experts. There are three main types of expert systems: advisory systems provide advice and recommendations to users, dictatorial systems fully control processes without human involvement, and criticizing systems analyze problems and proposed solutions to evaluate their effectiveness.

2. INTRODUCTION OF EXPERT
SYSTEM
An Expert System is defined as an
interactive and reliable computer-based
decision-making system which uses
both facts and heuristics to solve
complex decision-making problems. It is
considered at the highest level of
human intelligence and expertise. It is a
computer application which solves the
most complex issues in a specific
domain.

3. IMPORTANT CHARACTERISTIC OF
EXPERT SYSTEM:
The Highest Level of Expertise: The expert system offers the highest level of
expertise. It provides efficiency, accuracy and imaginative problem-solving.
Right on Time Reaction: An Expert System interacts in a very reasonable period
of time with the user. The total time must be less than the time taken by an expert
to get the most accurate solution for the same problem.
Good Reliability: The expert system needs to be reliable, and it must not make
any a mistake.
Flexible: It is vital that it remains flexible as it the is possessed by an Expert
system.
Effective Mechanism: Expert System must have an efficient mechanism to
administer the compilation of the existing knowledge in it.
Capable of handling challenging decision & problems: An expert
system is capable of handling challenging decision problems and delivering
solutions.

4. TYPES OF EXPERT SYSTEMS:
There are three basic types of expert systems:
Advisory
Dictatorial
Criticizing

5. ADVISORY
The Advisory Expert System module of the CRIF Credit Management Platform provides
sales & relationship managers with exactly what they need to complete a risk evaluation
of a company both when onboarding new customers and when monitoring and managing
existing customers.
With this module you can:
Have financial & economic analysis done automatically,
Accurately anticipate risks and discover opportunities,
Leverage all existing data sources as well as analytics to hone in on exactly where
potential risks or inconsistencies may lie,
Automatically receive intelligent insights which guide the sales / relationship manager to
thoroughly & quickly assess risk,
Improve employees’ decision-making—and business results,
Have a productive, positive customer engagement through the approval process.

6. DICTATORIAL
This kind of systems are widely used as process controlling
systems, where all actions (or almost all) are taken by an expert
system, because there is no way to involve a human or a human
perception is to slow to make proper decisions.

7. CRITICIZING
A problem is given with a solution. A system have to analyze them
and evaluate the effectiveness.
