When row, the reliability and maintanability, r&m Supportability Evaluation method in above-described embodiment 1 is executed, for example, executing Fig. 2-Fig. 4 described above
Shown in each step.
Embodiment 3:
The embodiment of the present invention illustrates that the embodiment of the present invention is calculating corresponding maintenance report further by specific model
When, how optimal configuration is selected from many allocation plans.Consider certain following equipment dependability maintainability protection
Problem: consider certain following equipment dependability maintainability protection problem: equipment includes four components As, B, C, D, wherein A, C component
It can repair, fault time meets exponential distribution, and failure rate is all 0.06 time/hour, and maintenance time meets the triangle of (1,2,3) hour
Distribution, and part B, D can not be repaired, fault time meets exponential distribution, and failure rate is all 0.02 time/hour, and maintenance process needs
The guarantee of maintenance personal and different maintenance and repair parts.The operating time of equipment is 30 hours, and system reliability block diagram is a string
Parallel system, as shown in Figure 6.Need to assess the pot life of long interior equipment at work is how many.
Obviously, this is a typical reliability and maintanability, r&m protection comprehensive assessment problem, needs to consider components/devices
Failure rate, maintenance time and Support Resource etc. factor, therefore based on Section four of the present invention of thinking, we are imitative using multi-method
True software Anylogic completes the modeling of this problem, is modeled first with Agent to each fault mode, either which kind of failure mould
Formula, grown form are all consistent, as shown in Figure 7: i.e. failure Agent includes failure and normal two states, normal condition
It can be issued message by itself random fault (being determined by service life distribution) or other failures of block diagram and be induced into failure state, fail shape
State can be finished by maintenance message be induced into normal condition (when failure can not repair, i.e., without corresponding maintenance support model,
This message would not be received, therefore, component will be in failure state once failing forever).When entering failure state, will produce
A raw faulty entity enters Discrete Event Simulation Models, if while when this failure and other fault correlations, message will be sent and drawn
Send out the generation of other failures.Since this example has 4 kinds of components, then this example will be made of 4 failure Agent.
After failure generates, if component can be repaired, maintenance and safeguard work are simulated by Discrete Event Simulation Models, such as Fig. 8 institute
Show: after components A and component C break down, faulty entity will be generated and enter Discrete Event Simulation Models, key code are as follows:
if(repairable)
main.Failures.take(new FailureInfo(this))；
Different repairing routes is selected by fault type, configures different Support Resources, and repairing queue, repairman are short
Scarce, spare part deficiency can all influence the time that maintenance is completed, while exiting Discrete Event Simulation System model when repairing and completing
The message repaired and finished is issued to the failure Agent model at place, is allowed to return to normal condition.Its key code are as follows:
agent.myFailure.receive("repaired").Emulation repeatedly after, can estimate current reliability, maintainability,
The pot life of system under protection index.
The mutual problem of transmission of failure is not considered first, i.e. the generation of failure is mutually indepedent, first fixes maintenance support index
Constant, from the angle estimator unit failure rate of reliability for system uptime influence.Therefore the maintenance of setting A and C is standby
Part each 2, maintenance personal 1, the repairing time is constant, without loss of generality, only adjusts the failure rate of components A, and emulate respectively
It is as follows system uptime to can be obtained 10000 times, it is seen that failure rate is higher, and system uptime is fewer.
| Failure rate | 0.04 time/hour | 0.06 time/hour | 0.08 time/hour |
| System uptime | 26.245 | 25.492 | 24.759 |
It is constant that guaranteed reliability's index is fixed again, when system can be used from the angle estimator parts for maintenance time of maintainability
Between influence.Therefore maintenance and repair parts each 2 of A and C are set, maintenance personal 1, adjust the maintenance time of components A and C, and point
It is as follows system uptime Fang Zhen not to can be obtained 10000 times, it is seen that the increase of repairing time can reduce system uptime, but shadow
It rings little, it is clear that be not key factor.
| Repairing time | (1,2,3) hour | (2,4,6) hour | (3,6,9) hour |
| System uptime | 25.47 | 25.282 | 24.961 |
It is constant that Reliability Maintenance index is fixed again, when system can be used from the angle estimator parts for maintenance time of protection
Between influence.Maintenance personal's quantity is adjusted first, and emulates that system uptime to can be obtained 10000 times as follows respectively, it is seen that when
When not having repairman, system degradation is that repairable system, system uptime do not substantially reduce completely, and need two to repair simultaneously
The case where reason personnel repair seldom occurs, therefore 1 repairman is sufficient.
| Repairman | 0 people | 1 people | 2 people |
| System uptime | 18.679 | 25.424 | 25.43 |
Fixed maintenance personal is 1 people, then adjusts the spare part quantity of Awaiting Parts A and C, and emulates 10000 times can obtain respectively
It is as follows to system uptime, it is seen that when not having spare part, system is also degenerated for repairable system, system uptime be not big completely
A possibility that big to reduce, and failure twice occurs for interior generation the same part at work, is not small, therefore appropriate increase spare part number
Help to improve system uptime.
| Repair spare part | 0 | 1 | 2 |
| System uptime | 18.562 | 25.439 | 27.179 |
Finally, investigating the influence of system relationship failure, it is assumed that components A failure can also cause part B failure, key code
Are as follows:
for(Failure f:relativeError)
send("error",f)；
It is as follows with 10000 results of failure independence contrast simulation.If therefore relevant failure can also reduce the available of system
Time.
| Whether it is associated with | Onrelevant | Association |
| System uptime | 25.439 | 22.827 |
In conclusion for the system evaluation problem comprising reliability and maintanability, r&m protection, use multi-method modeling can be with
