Prokopenko R. The modelling of semistructured problems in decision support systems.

Object of research are information processes in a control system of economic objects. The purpose of research is modelling semistructired problems in systems of support of acceptance of the decisions, providing increase of efficiency of acceptance of administrative decisions both steady functioning and development of economic object; methods - economic-mathematical modelling, the theory of acceptance of decisions, expert estimations, an artificial intellect. Results: the concept of modelling semistructired problems is developed at management of the economic objects, being making system of support of acceptance of the decisions, based on application of methods of an artificial intellect which introduction allows to increase efficiency allows to increase speed of acceptance of administrative decisions and to raise(increase) them argumented. Within the framework of the offered concept the complex of economic-mathematical models of the decision semistructired problems(tasks) is developed at management of economic activities: the economic-mathematical model of the decision semistructired problems(tasks) is developed by revealing relationships of cause and effect which allows to define(determine) main principles of the decision of these problems(tasks) the person accepting decision (PAD) and to use the received rules for support of acceptance of decisions; the method of generation of the administrative decision which allows to reduce time of search of different variants of the decisions having identical efficiency, and enables PAD to choose the decision most adequate to concrete conditions; economic-mathematical model of synthesis of system of support of acceptance of decisions which allows to provide effective interaction between different parts DSS and to raise accuracy of acceptance of administrative decisions. The method of formalization of the description of the basic attributes of a situation is developed at the decision semistructired problems. The model of audit of control systems with the help computerDSS is developed. Experiment on introduction of recommendations for management of marketing activity of Open Society " МК Azovstal " with the help of system of support of acceptance of decisions is carried out(spent). Novelty: the concept of modelling semistructired problems(tasks) at management of the economic objects, being making system of support of acceptance of the decisions, based on application of methods of the artificial intellect, allowing to increase efficiency of acceptance of administrative decisions and to raise(increase) them argumented; The economic-mathematical model of the decision problems by revealing relationships of cause and effect which is based on application semantic neuronetwork, allowing to define(determine) main principles of the decision of these problems ЛПР and to use the received rules for support of acceptance of decisions that enables to raise(increase) efficiency of acceptance of administrative decisions; the method of generation of the administrative decision, based on evolutionary methods of search which allows to reduce time of search identical on efficiency of variants of decisions, and enables PAD to choose the decision most adequate to concrete conditions; the economic-mathematical model of synthesis of system of support of acceptance of decisions which is based on principles of the flexibility, allowing to provide effective interaction between different parts DSS and to raise adequacy of administrative decisions.
