Opis:
There is presented the application of the integrated software tools to the reliability of the improved exemplary complex technical system prediction. There are considered three ways of the exemplary system reliability improvement, i.e. a hot single reservation of its components, a cold single reservation of its components and replacing its components by the improved components with reduced intensities of departure from the reliability state subsets. Automatically obtained, using the computer program CP 8.16, the evaluations of these ways improved 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 presented. Moreover, in the case when the improved system is repairable, its renewal and availability characteristics are estimated using the computer program CP 8.8 with appropriately given data.

Opis:
There is presented the application of the integrated software tools 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 at the particular operation states because of the lack of statistical data is performed throw the arbitrary fixing their values assumption. Next using the computer program CP 8.3 the automatic 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.

Opis:
The paper is composed of six parts and presents the software tools created in the scope of the Poland-Singapore Joint Research Project, the Integrated Safety and Reliability Decision Support System – IS&RDSS. In the paper first part, there are briefly described all computer programs with pointed aims. Dependencies between computer programs and possible transitions using this integrated package of software tools are presented at the scheme algorithm. In the remaining paper parts, there is presented the application of the computer programs, being in the package of software tools, to the reliability analysis of an exemplary complex technical system.

There is presented the application of the integrated software tools to the operation and reliability of an exemplary complex technical system prediction. The computer program CP 8.5 is used to determine the unconditional mean sojourn times and the limit transient probabilities of the exemplary system operation process at the particular operation states evaluations. Using the computer program CP 8.6 there are performed 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. Finally, in the case when the system is repairable, its renewal and availability characteristics are estimated from the results of computer program CP 8.8.

Opis:
There is presented the application of the integrated software tools to the operation and reliability of an exemplary complex technical system optimization. First using the computer program CP 8.9 there are determined the optimal limit transient probabilities of the exemplary system operation process at the particular operation states maximizing the system lifetime in the reliability states not worse than the critical reliability state and its optimal sojourn times at the particular operation states. Program CP 8.9 allows also for automatic evaluation of the exemplary system optimal unconditional multistate reliability function, the optimal expected values and standard deviations of its unconditional lifetimes in the reliability state subsets and the optimal mean values of its lifetimes in the particular reliability states. Moreover, in the case when the system is repairable, its optimal renewal and availability characteristics are obtained using the computer program CP 8.11.

Opis:
The paper is concerned with the application of the original mathematical models and supporting them software technologies to forecast, analyze and optimize reliability and risks for complex systems (system is defined as a combination of interacting elements organized to achieve one or more stated purposes). Functionality and usability to analyze information system processes and standard processes in system life cycle are presented. Rational use of the proposed results allows to go «from a pragmatical filtration of information to generation of the proved ideas and effective decisions». Effects are demonstrated by examples.
