Introduction. Since 2004, an Analytical Expert Bridge Management System (AESUM) which accumulates information on bridges on public roads of Ukraine has been developed and implemented by the State Road Agency of Ukraine (Ukravtodor). Analytical information from the database of the AESUM software is used at all levels of the road sector system, filling of the AESUM database with the information on inspections and certification is carried out regularly, all changes in the classification of roads and bridges are taken into account, etc.
Problem statement. It is established that the general management system includes three most important parameters: information acquisition and its analysis; definition of an optimal strategy; rational allocation of funds. The analysis of publications shows that the created and implemented systems in different countries have much in common: there is a database on the bridges; planning of works is carried out; ranking of the facilities for the priority work performance is carried out. But there are also significant differences in the systems of different countries.
Purpose. A detailed consideration of the functional of AESUM and its comparison with the well-known world bridge management systems to determine the future directions of the development of the software package.
Materials and methods. The AESUM database contains about 150 technical parameters for each bridge. It stores the detailed information on individual elements of the bridges such as bridge span, bearings, and foundations, as well as photos and drawings. From the results of the surveys, the defects are recorded in a defects record for each group of elements with a detailed description, specification of a distribution area and the evaluation of their impact on the element’s state. Operational state of the facility is calculated in the automatic mode. For each bridge element it is possible to determine the residual lifetime with the construction of the degradation curve which allows predicting the state of the facilities elements for a certain period of time in the future. Ranking of the bridges by the repairs need is completed by two indicators - the operational state and the road category. Module for strategic management of repairs and operational maintenance of bridges has been developed within the AESUM software. During planning, two functions of the target were proposed by which the optimal solution is adopted: minimizing the average annual level of degradation and minimizing the cost of repairs and operational maintenance. Options for developing the strategies with a limited budget are predicted.
Results. To date, the functional of the AESUM software is comparable to the major foreign Bridge Management Systems.
Conclusion. It is concluded that the AESUM software complex contains basic parameters of the Bridge Management System and the priority areas for its improvement are identified.
