The paper presents the results of a study, the purpose of which was to automate the process of designing ventilation for a residential construction project. The ventilation system is one of the most complex life support systems of a building, which has a significant impact on the level of comfort of residents. Automation of the design of such a system will reduce the number of errors, reduce the time and labor required for design. During the study, the design process was considered as a business process consisting of individual works. When modeling this process in the “As Is” notation, the connection of the ventilation system with other engineering systems and a number of other important factors were taken into account. In the process model, the most time-consuming and, at the same time, algorithmizable works were identified. Subsequently, these works were automated using code created in the Visual Studio environment in C#. This made it possible to reduce the number of errors and reduce the time spent on creating a ventilation system project.

Today geographical information systems are used by operating companies for solving extensive distributed utility networks service and development issues. Designing and the subsequent creation of geographically distributed corporate enterprise geodatabase is needed for taking into account the requirements imposed by all divisions of the enterprise on GIS. On account of the complex distributed multi-level structure of the enterprise database the detailed consideration of all elements, parts of the enterprise geodatabase, is required. The enterprise database structure has been considered from the point of view of the database elements. The database of the whole enterprise is a set of databases of enterprise local subdivisions. The divisions use data about neighboring division territories in their work to perform their tasks. The subdivision database consists of two parts: a unique chunk and data about neighboring division objects. The base of the common data includes objects information which is required for more than one local subdivision. The data required for three neighboring divisions is a crosscutting of three neighboring division databases. Corporate database and entering into its composition local subdivision databases consist also of an attributive and spatial information. Besides it is necessary to perform spatial differentiation, layer differentiation and attributive field differentiation for more flexible monitoring of access permissions in the database. The suggested approach based on the set-theoretical spatial data presentation and analysis allows to realize the consistent structure of the distributed database.

The method of application of fuzzy logic to solve the problem of spatial planning using geographic and information systems is described. The spatial arrangement of objects on the map is used as input factors of the solution, to find which a model of the spatial descriptions of objects using a bitmap representation is constructed. The way of formalizing fuzzy judgments about positional relationship of objects and the system of inference making based on the fuzzy logic methods is developed. An example of using the method described in this article to determine the sanitary protection zone of industrial waste landfill in the territory of the Republic of Bashkortostan is given
