Testing the integrated package of tools supporting decision making on identification, prediction and optimization of complex technical systems operation, reliability and safety. Part 1. Integrated Safety and Reliability Decision Support System – IS&RDSS

Kołowrocki K., Soszyńska-Budny J., Ng K. M.

Journal of Polish Safety and Reliability Association

Vol. 2, No. 2

361--372

The paper is composed of six parts and presents the main practical tool created in the scope of the PolandSingapore Joint Research Project, the Integrated Safety and Reliability Decision Support System - IS&RDSS. In the paper first part, there are presented the procedure of the IS&RDSS usage in the form of detailed and clear scheme-algorithm and the list of the project final reports and these reports supporting bibliography. In the remaining paper parts, there is presented the IS&RDSS application to the reliability analysis of an exemplary complex technical system.

There is presented the IS&RDSS application to the operation and reliability of an exemplary complex technical system prediction. There are performed, the unconditional mean sojourn times and the limit transient probabilities of the exemplary system operation process at the particular operation states evaluations. The evaluations of the exemplary system unconditional multistate reliability function, the expected values and the standard deviations of its unconditional lifetimes in the reliability state subsets and the mean values of its lifetimes in the particular reliability states are performed as well. Moreover, in the case when the system is repairable, its renewal and availability characteristics are estimated.

There is presented the IS&RDSS application to the operation and reliability models of an exemplary complex technical system unknown parameters identification. There are performed in the paper, the exemplary system operation and reliability analysis and modelling. The identification of the probabilities of transitions this system operation process between the operation states and the conditional mean values of this process sojourn times in the particular operation states because of the lack of statistical data is performed throw the arbitrary fixing their values. assumption. The evaluation of the system components unknown intensities of departures the reliability state subsets and the identification of the exponential forms of their multistate reliability functions on the arbitrarily fixed statistical data coming from the system components states changing processes are performed as well.
