scram.cutsets: Fault Tree Minimal Cut Set Determination Acquired from SCRAM

In FaultTree.SCRAM: Interaction Between 'FaultTree' on R and "SCRAM"

Description

Interconnection with SCRAM by transferred XML files permits advanced calculation of minimal cutsets

Usage

scram.cutsets(DF, method="mocus")

Arguments

DF	A fault tree dataframe such as returned from ftree.make or related add... functions. Fault tree elements must be either probability or exposed types, gates other than OR will be converted to AND. Fault tree shall not contain PRIORITY, ALARM nor VOTE gates.
method	A character string directing the method of cutset determination, must be "mocus", "bdd", or "zbdd".

Details

"And one ring to bind them all ..." This function calls ftree2mef, callSCRAM, and readSCRAMcutsets appropriately for the entered ftree object. Temporary files for SCRAM input and output are produced in the process.

Value

Returns a list of matrices containing tags of minimal cutsets. Each matrix on the list contains cutsets of a specific order, which is also the list item number.
