cutsets | R Documentation |
Determines minimal cutsets by various methods.
cutsets(DF, ft_node=1, method="mocus", by="tag")
DF |
A fault tree dataframe such as returned from ftree.make or related add... functions. |
ft_node |
A gate node ID treated as top of (sub)tree to be calculated. |
method |
The method for calculation either 'mocus' or 'prime-implicants' |
by |
Selection of identifier for each element of the cutset either 'tag' or 'id' |
Returns a list of matrices for each of cut set lengths found. Each element is defined by its unique ID assigned in the fault tree or by its unique Tag applied by the user.
