Embodiment Construction
[0123] A repairable mixed public reserve system model and reliability simulation algorithm with voting function of the present invention, its model is as follows Figure 1 shown; its reliability simulation algorithm flow consists of 11 modules, one of which is the main module, such as Figure 2 , others are calling modules, such as Figure 3 to Figure 12 Indicates that there is also a calling relationship between calling modules.
[0124] The N / R / K system simulation adopts event-driven and time-advancing mechanism. The general algorithm flow is as follows: First, the first fault event of each component and switch is generated by sampling, and each event is processed in chronological order. Generate maintenance and failure events of each component and switch, and accumulate statistics, and advance the processing of events until the time reaches the simulation time. After the above-mentioned process is simulated several times, each statistical quantity is calculated to obtai...

Abstract
A reliability simulation algorithm for a model of a reparable and hybrid public standby system with a voting function comprises the following steps of: 1, reading part information and simulation information: Ci, S, Ftype, Fa, Fb, Fc, Rtype, Ra, Rb, Rc, Stype, Sa, Sb, Sc, WorkStyle, StandbyTypa, RestoreWork, S.Pres, S.SProb, ST, TN; 2, setting the current simulation number of times (SN hereinafter) as zero; 3, adding one to the simulation number of times, SN=SN+1; 4, initializing the simulation data for each part, carrying out a first fault sampling to each part to generate event set (ES hereinafter) ES (ET, CS, Etype), arranging the ES in a chronological order and carrying out a first sampling processing; 5, taking out from the event set a first event ES (ET, EC, Etype) 1 and processing the event by invoking event list processing; 6, determining whether the current simulation number of times is less than the total simulation number of times (TN herein after), shifting to step 3 if SN<TN, and shifting to step 7 otherwise; 7, calculating reliability index; 8, finishing. The invention has a good utility value and a wide application prospect in the technical field of system reliability modeling and simulation.
Description
technical field [0001] The invention relates to a repairable mixed public reserve system model and a reliability simulation algorithm with a voting function, and belongs to the technical field of system reliability modeling and simulation. Background technique [0002] At present, reliability has become an important indicator of product or system quality, and the reliability level of a product or system has become an important symbol of a country's industrial development level, and is highly valued by countries all over the world. When analyzing and designing the reliability of a product or system, in order to predict, estimate and evaluate its reliability, it is first necessary to establish a suitable system reliability model; secondly, the solution method of the model should be easy to implement and have high efficiency . [0003] In system reliability design, redundancy design is one of the important means to improve system reliability. Like the voting system, the reser...
