Intelligent Information Systems
The modern economy is unthinkable without information.
Thousand enterprises, millions of taxpayers trillions of rubles, registers of
shareholders - all the information streams is necessary to evaluate, treat,
draw the necessary conclusions, make the right decision.
Modern economist should be able to make informed
decisions. For this purpose along with the traditional knowledge, such as the
basics of management, the basics of foreign trade, banking, administration,
taxation, must have information on the construction of information systems.
Intelligent technology is one of the last stages in
the development of analytical technologies. Analytical techniques are
methods which based on some models,
algorithms , mathematical theorems and thanks to famous database, they estimate
values of the unknown parameters and characteristics . The most
simple example of analytical technology is the Pythagorean theorem , which
allows the long side of a right triangle to determine the length of the third
side. Another example are the methods by which the human brain processes
information .
Analytical technologies needed primarily to make
important decisions - managers , analysts , experts and consultants. The
company's revenue is largely determined by the quality of these solutions -
accuracy forecasts optimally chosen strategies. The most common analytical
techniques are used in the following tasks : to predict exchange rates,
commodity prices, demand , revenue , unemployment , the number of insurance
claims , etc.
Usually for real-world problems of business and
production there is no clear solution algorithms. Previously, leaders and
experts solve such problems only on the basis of personal experience. With the
help of modern analytical technologies different systems are built in order
to significantly improve the efficiency of solutions.
There are a lot of approaches and classifications of
informational systems:
– granularity of tasks;
– automatical functions;
– the degree of automation implemented functions;
– the scope and nature of the use of information.
t is known that during people's training there
are a lot of different levels of subject teaching: play (memory), the solution
of standard problems (skills and abilities), the decision of non-standard,
creative tasks (knowledge, an active understanding).
Intelligence can manifest in different areas, but we
will consider it as the ability of solving problems, because this area is
typical manifestations of intelligence. Tasks are standard and nonstandard. For
standard tasks, algorithms are known. For non-standard, they are unknown.
Therefore, the solution of the problem is a non-standard problem. The
"standard" concept is relative as " suspense ". it means
that algorithm can be famous for some information or it could be not available
in a certain time. That is why one of the tasks can be standard, the other is
not. The way of solving problems or to develop an algorithm is to translate the
problem of non-standard to standard discharge.
In mathematics and cybernetics problem is considered
solved if known algorithm for its solution.
People used to think that this work is very creative,
which существенно не формализуемой и requires the involvement of a man with his
"natural" experience and intelligence. It should be noted that there
is a technology of Inventive Problem Solving (TRIZ), which attempts, according
to many experts, is quite successful, allowing some degree of formalized
procedures for creative problem solving.
Considered intellectual tasks associated with the
development of algorithms for solving previously unsolved problems of a certain
type.
A distinctive feature and a major source of efficiency
of algorithms is that they reduce the solution to a complex problem to a
specific sequence rather simple or even basic tasks. As a result, the problem
which is nor solved becomes solvable. Background information is input to the
algorithm, at each step, it is converted in such a form is sent to the next
step, resulting in the output of the algorithm is obtained information
representing the solution of the problem. The algorithm can be executed by such
a system which is capable to realize basic operations of the various steps of
the algorithm.
