In this sample, we have a complex series/parallel system with 8 modules and 7 nodes.
1. Input the configuration of the system
2. Click the first RUN, then you will get below:NodesNum = 7 ModulesNum = 8InputNode = 1 OutputNode = 5A = (1, 2)B = (2, 3)C = (3, 4)D = (3, 4)E = (1, 6)F = (6, 7)G = (7, 4)H = (4, 5)
3. Input the numeric value of reliability for each module:Result:
The diagram is shown below:System Reliability = (1-(1-Ra*Rb*(1-(1-Rc)*(1-Rd)))*(1-Re*Rf*Rg))*Rh
4. Input the numeric value of failure rate for each module:0.9, 0.8, 0.7, 0.8, 0.9, 0.5, 0.6, 0.9Click the second RUN, then you will get below:Result:The diagram is shown below:
System Reliability = (1-(1-Ra*Rb*(1-(1-Rc)*(1-Rd)))*(1-Re*Rf*Rg))*RhGiven Ra = 0.9, Rb = 0.8, Rc = 0.7, Rd = 0.8, Re = 0.9, Rf = 0.5, Rg = 0.6, Rh = 0.9,
Rsystem = 0.6876576000000001
Return1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5Click the third RUN, then you will get below:Result:The diagram is shown below:
System Reliability = (1-(1-e-1.5t*e-2t*(1-(1-e-2.5t)*(1-e-3t)))*(1-e-3.5t*e-4t*e-4.5t))*e-5tThe diagram of R(t) vs time t is shown below:
