The procedural approach to reliability of objects of the raised level of responsibility

Abstract

The hypothesis of non-compliance presented in the regulatory methodology was grounded for building operations with the actual facility life of the facilities and buildings under the conditions of time lag. Briefly, the tasks for strategic development of the construction are presented in the following form: quality-reliability-safety-functionality-aesthetic qualities-amenities-economy. It is set that the listed tasks are multiplicative and require the systematic solution not only at the multidisciplinary but also at the transdisciplinary level. A comprehensive system "human-facility-technology-equipment-environment" is formed. It is established that the factor mutual interference of the elemental composition provides a possibility to implement the variable process approach of multi-modular modeling with component rating on the characteristic of marginality and accentuating. It is found that the absence of the single technical guidance on technical support of construction facilities of the increased level of responsibility at various stages of life-cycle. A structural model for technical support is prepared for construction of the increased level of responsibility. It is defined that the prognosis models for a 100-year–period functioning cannot be non-specific, they require the formation of the unique apparatus for evaluation of the initial characteristics of the facility that is adapting to changes of social-ecological-economic and technical paradigms during different time lags. A scheme is provided for categorizing the limit state of construction facilities, taking into account the factor impact and the responsibility of possible changes. The possibility of applying the combinatorial law towards the construction facilities is justified as to the comprehensive structured system with a functionally consistent and interdependent element base of a given finite set. Criteria maximum of the complexity profile in the existing structured system of construction facilities of the increased level of responsibility is proposed to consider parametric efficiency. The process approach to the development of research and development support for construction facilities of the I level of responsibility is based on the principle of anticipatory reflection of the validity of the safety parameter, the creation of an infographic model of a system with multiparameter characteristics of the life cycle stages. A mathematical model is developed for the change in the safety index of construction facilities of the increased level of responsibility as a system represented by an extended structure of components, with various impact factors at risk-rejection in a random segment of the operation period, and the concept of a "time lag" is introduced. Empirical indicator of the minimum value of the hazard severity is established and a proportionality coefficient having the dimension of the damaging factor is justified. It is proposed to apply the developed methodology as an addition to the development of research and development support programs, a model for verification by the level of responsibility and structured monitoring systems for different stages of the life cycle of construction facilities of the I level of responsibility.
