There are two issues to be addressed in the automatic Fault Tree Analysis (FTA) and Failure Mode and Effect Analysis (FMEA) approaches: resource fault and channel fault are not considered when generating the artifact flow graph (AFG) from Little-JIL processes. The AFG is incomplete, thus the fault trees and FMEA reports automatically generated partially based on AFG is incomplete. In this paper, we put forward to an approach of introducing resource instances and channel instances into fault propagation in Little-JIL processes. Thus, it makes the FTA and FMEA for Little-JIL processes to be much more effective. That is to say, how resource instances and channel instances might affect the fault propagation in Little-JIL processes is taken into account while performing these two automatic safety analysis techniques.
