Information basis of decision support system for high school timetable creation as an example

This article is about a task of learning of effective use of information technologies with the decision support. The criteria for evaluating the activity of economic and social systems are systematized, their classification and areas of application of particular criteria of different nature are given. It is proposed to integrate knowledge in the field of information technologies in order to decision support on example of an actual task of scheduling lessons. The initial data are determined, the factors of the model are classified, a mathematical model is designed, its limitations are proposed. Methods for obtaining schedule quality criteria from various points of view and integral quality criterion design are presented. The limitations of possible solutions are considered and classified. Some examples of formula criteria unusability are given. The selection of optimization algorithms based on an integral criterion is substantiated. The transition from structural models of the activity of decision makers to information models of decision support systems is shown. The concept of an expert decision support is offered by an estimation of its difficultly formalized actions on change of parametric values of the system. Sets of objects of the system are compared to the essences of the information model, and its improving transformations are given. The variants of the information model with different degrees of normalization are considered; their comparative advantages and disadvantages are shown. The directions of development of the information model in the structure of the automated management system of the university are determined. As a conclusion a possibility of increasing the efficiency of the activities of complex socio-economic systems through the rational use of mathematical, information and simulation tools is proved. It is shown that this area of activity is currently promising from the point of view of the effective application of the efforts of a specialist in the field of informatics.
