Are you eagerly waiting for the era where everything is modernized and controlled by expert machines? Well, that day is not so far, because the recent development in the expert system shows a path to achieve this advancement development. Of course, it may be a milestone among the inventions made by humans.
For human beings, expert systems are definitely a gift because it helps you in several ways that can go beyond your expectations. In this article, we will explain the Applications of Expert Systems.
Generally, expert systems are computer application that represents some non-algorithm expertise for fixing certain issues. It is a computer program, which stimulates the intelligent process of the human to solve complex problems in a certain domain.
The features of an expert system distinguish it from traditional tools of decision support and programming tools. Learn everything about the expert system along with its application from here.
Reasons to use expert systems
Have you ever thought about the reasons to use an expert system? Actually, expert systems are necessary to cover up the limitations incorporated with the traditional human decision-making process. Some of the limitations are listed here.
- Humans often forget important details of the problem
- They get tired from the mental and physical workload
- They are inconsistent in their regular decisions
- They are slow in recalling data stored in memory
- They have limited working memory
- Humans hide, lie, and even die
- They can avoid decision-making responsibilities
To overcome these limitations, expert systems are highly essential. Additionally, the expert system can be utilized anytime and anywhere whereas experts are not available always.
It is cost-effective and 100% reliable and consistent when making a decision towards a complex issue. Most importantly, they are extremely good at explaining the reason behind the particular decisions.
Historical applications of the expert system
As mentioned already, expert systems are quite different from the traditional software programs (offers access to computer capability in terms of arithmetic power) and dissimilar from the decision support systems (renders access to computer capability in terms of information distribution).
For making a decision under several conditions, the expert system captures and then distributes the human expertise. It is worth to mention that expert systems clone the experts by gaining their knowledge.
It typically provides cost-effective services in many areas, which need symbolic knowledge processing and thumb rule for solving problems. Diagnosis and treatment of human disease was the first application of expert systems.
The motive of this system is to find out the symptoms and offer appropriate treatment. MYCIN is the best example of this system, which determines the infection type the patient suffers from and then provides the corrective treatment.
The applications of expert systems expanded further and serves in many areas. Below mentioned are major areas in which the expert system works well. For your better understanding, each area specified with a real-time example.
- Nuclear power plant operation – g. Crisis management
- Situation analysis and understanding – g. Military operations
- Financial services – g. Bank loan applications
- Software development – g. Automatic programming
- Geological exploration – g. Mineral assessment
- Manufacturing and engineering – g. Floor layout
However, the expert system cannot able to solve all the problems because it has certain limitations. For instance, currently available expert systems are extremely slow and need more financial support to develop.
Additionally, they are unable to find their own knowledge boundaries.
Applications of Expert Systems
The applications of expert systems can be ranging from industrial to the medical field. The applications usually recognize their way into several areas of knowledge work and solve out the issue.
Applications of expert systems are divided into seven different classes, which give enough insight into expert system use.
Diagnosis and troubleshooting of devices of alltypes
This class contains machines, which figure out faults as well as suggest corrective methods for the malfunctioning process and device. The first knowledge area where expert system technology is applied is a medical diagnosis, as mentioned before.
For example, the Shortlife expert system was launched in 1976. However, the diagnosis of engineering expert systems surpassed the medical diagnosis quickly.
Planning and scheduling
Systems come under this class analyze one or more difficult and interacting goals to figure out the set of actions to reach those goals.
They offer an informative temporal ordering of those actions by considering the material, personnel, and various other constraints. The best example of this class is airline scheduling of the flights, manufacturing process planning, and so on.
The configuration of manufactured objects
Configuration is extremely vital of the expert systems applications. Configuration is typically a solution to the issue, which synthesized from the set of given elements relevant to the set of constraints.
Configuration applications were pioneered by computer firms because it facilitates the semi-custom minicomputers manufacturers i.e. McDermott at 1981.
You will find this technique in several industries such as manufacturing, modular home building, etc.
Financial decision making
The financial industry has been a vital user of the expert systems techniques. To help bankers in finding whether to make a loan to individuals or businesses, advisory programs have been crafted.
On the other hand, insurance firms have utilized expert systems in order to determine the risk present by the customers and the cost of the insurance. Foreign exchange trading is the typical application of this class.
Design and manufacturing
This class system helps in the design of the processes and physical devices. It ranges from the superior conceptual design of the abstract entities to the configuration of the factory floor of the manufacturing processes.
Knowledge publishing
It is a new class but potentially an explosive area. Delivering knowledge relevant to the user’s issue is the basic function of the expert system.
In this category, you will find two widely distributed systems and they are an advisor (suggests the user on the correct grammar usage in the text) and tax advisor (helps a tax preparation program including tax tactics, strategy, and individual tax policy).
Process monitoring and control
Under this class, systems usually analyze the real-time information from the physical device along with the motive of predicting trends, noticing anomalies, and controlling both failure correction and optimality.
You will find the best real-time systems, which monitor processes actively in the steel making & oil refining industry.
Conclusion
Expert systems have grown powerful to more powerful in a very less time. Although its efficacy in a number of areas is still to be assessed, it has been doing marvels in a number of verticals. It has helped businesses and industries in revolutionizing their operations and reap the fruit of science in its best form.
