The process implementing of modern information systems in medium and large enterprises, more and more often is associated with a number of problems that can occur already at the planning stage. Often incorrect or incomplete separation of problem factors causes that the procedure of implementation of such a system can significantly lengthen, and in the worst case end in failure. Therefore, a crucial part of this process, it is possible to determine the potential problems and consequences thereof already at an early stage in the project. Modern technologies of artificial intelligence are increasingly becoming an indispensable tool supporting decision-making in different areas of economic activity. In the following work was analyzed the effectiveness of the use of an expert system in the implementation of information systems based on the skeletal system PC-SHELL. On the basis of research was developed scheme of building the knowledge base for future expert system to support the implementation of the information systems.

Sight is the most important sense of a human. For the most of the society, the perception performed by the sight organ is perceived as something very natural. Reflection on life without the sight is not common, which slows down the technological development aiming at reducing the social exclusion of persons with sight disabilities. The dynamical development of advanced technologies does not provide solutions for all the cases of illness. However, many tools exist which allow people with visual disabilities to interact with the outside world. In most cases these tools allow only for the exchange of very basic information. We present some problems associated with the visualization of images for the blind, with the attention concentrated upon business graphics. We also give some propositions to enhance the level of non-visual perception of images with the use of specialized tactile equipment.
