Review article

In this article, the authors raises the problem of assessing the residual resource of an object consisting of several buildings and structures. Four different approaches to solving this problem are presented. The advantages and disadvantages of them are considered, and the application areas of these approaches are indicated. Within the framework of these approaches, one can use the direct enumeration method, the combinatorial method, the algebra of logic, and the general logical-probabilistic method. The authors has developed two possible options for calculating the residual resource of these objects using the general logical-probabilistic method. It is proposed to develop a methodology for calculating the residual life of such objects before conducting a survey. The authors indicates the main points that must be included in the developed methodology.
