Estimation of the residual resource of several buildings and structures as a single object

Abstract

Abstract In this article, the author raises the problem of assessing the residual resource of an object, which consists of several buildings and structures. Four different approaches to solving this problem are presented. The advantages and disadvantages of these approaches are presented. The areas of their application are indicated. Within the framework of these approaches, one can use the direct enumeration method, the combinatorial method, the algebra of logic, the general logical-probabilistic method. The author 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 the survey. The author indicates the main points that must be prescribed in the developed Methodology. An example of calculating an object consisting of five buildings is given. The scheme of functional integrity is constructed according to the general logical-probabilistic method. In the program complex “Arbiter” the static and probabilistic-time calculation of the given scheme is performed. Then the calculation of the object as a whole was carried out according to the “2 of 5” system. As a result, the value of the probability of failure-free operation and the residual resource of the object as a whole is shown.
