Предложенная схема управления техническим состоянием пролётного строения позволяет с большой точностью рассчитывать надёжность конструкции и прогнозировать её изменения, гибко реагировать на динамику эксплуатационных условий, а также осуществлять оптимальное руководство процессами по критерию «надёжность-затраты».

The proposed scheme of control of technical condition of the span allows to calculate with a great precision design reliability and to predict its changes, to respond flexibly to the dynamics of the operating conditions, as well as to control optimally the processes by the criterion «reliability-cost». Keywords: railway engineering structures, span, reliability, security, recursive algorithm, optimal interval.
