In the PhD dissertation [6] optimization models were developed for the pavement management system, which could help planning the optimal maintenance work. This model can be generalized for those engineering structures, where there are several types of structures and for each structure there are many components with many different types of deterioration options and duty uses. The condition of application is: the deterioration of certain components not only depends on time, but on the extent of use. In this paper we would like to present the development of Engineering Structures Management System, the different models, and furthermore a practical application the deterioration model of car parts and the planning of their maintenance. © 2011 IEEE.
