Podgorny Institute for Mechanical Engineering Problems of the National Academy of Sciences of Ukraine Abstract The problem of synthesis of optimal configurations of spherical objects is considered. The basis is a general approach to the formalization of the configuration space of geometric objects. The analysis of models is carried out, their typology and information technologies for structural synthesis of complex spherical objects are offered. Approaches to the development of new information technologies for solving problems based on their generalized information-analytical model are proposed. Data is transformed into an object- oriented structure for visualization of spherical configurations. Keywords 1 Spherical object, configuration, analytical model, information technology 1. Introduction The term configuration is understood as appearance, outline and also the relative positioning of objects and their parts. In mathematics, as a rule, the configuration means some placement of points in space. The problem of synthesis of spatial configurations will be considered as the definition of such a property of geometric objects that would satisfy the given relations (constraints, properties) and would deliver an extremum to a certain quality criterion. In this article, we confine ourselves to a class of geometric objects of spherical form. However, the results obtained can be generalized to broader classes of spatial objects. A significant number of publications testify to the importance of the problems of spatial synthesis of spherical objects. The article [1] presents an overview of the works devoted to this topic, containing more than 60 references. In [2] - [10] a number of different approaches are considered for the search for optimal spherical configurations. Papers [11] - [16] describe practical applications of problems of placing spherical objects with additional constraints. It should be noted that when considering this class of problems, much attention is paid to mathematical modeling of systems with spherical objects and the development of special methods for nonlinear optimization to solve them. Issues related to information support, analysis of the data structure and ways to transform geometric information in the optimization process are not fully covered. The purpose of this paper is to describe the possibilities of using modern information technologies when considering the investigated class of problems based on existing mathematical models and analysis of optimization methods.
