Barrier analysis (BA) is an analysis technique for identifying hazards specifically
associated with hazardous energy sources. BA provides a tool to evaluate the
unwanted flow of (hazardous) energy to targets (personnel or equipment) through
the evaluation of barriers preventing the hazardous energy flow
Barrier analysis is a powerful and efficient system safety analysis tool for the discovery
of hazards associated with energy sources. The sequentially structured procedures
of BA produce consistent, logically reasoned, and less subjective judgments
about hazards and controls than many other analysis methods available. However,
BA is not comprehensive enough to serve as the sole hazard analysis of a system,
as it may miss critical human errors or hardware failures not directly associated
with energy sources
Markov analysis (MA) is an analysis technique for modeling system state transitions
and calculating the probability of reaching various system states from the model.
MA is a tool for modeling complex system designs involving timing, sequencing,
repair, redundancy, and fault tolerance. MA is accomplished by drawing system
state transition diagrams and examining these diagrams for understanding how certain
undesired states are reached and their relative probability. MA can be used to
model system performance, dependability, availability, reliability, and safety. MA
describes failed states and degraded states of operation where the system is either
partially failed or in a degraded mode where some functions are performed while
others are not
Markov chains are random processes in which changes occur only at fixed times.
However, many of the physical phenomena observed in everyday life are based on
changes that occur continuously over time. Examples of these continuous processes
are equipment breakdowns, arrival of telephone calls, and radioactive decay.
Markov processes are random processes in which changes occur continuously
over time, where the future depends only on the present state and is independent
of history. This property provides the basic framework for investigations of system
reliability, dependability, and safety. There are several different types of Markov
processes. In a semi-Markov process, time between transitions is a random variable
that depends on the transition
Petri net analysis (PNA) is an analysis technique for identifying hazards dealing with
timing, state transitions, sequencing, and repair. PNA consists of drawing graphical
Petri net (PN) diagrams and analyzing these diagrams to locate and understand
design problems
Models of system performance, dependability, and reliability can be developed
using PN models. PNA is very useful for analyzing properties such as reachability,
recoverability, deadlock, and fault tolerance. The biggest advantage of Petri nets,
however, is that they can link hardware, software, and human elements in the
system
The PNA technique may be used to evaluate safety critical behavior of control
system software. In this situation the system design and its control software is
expressed as a timed PN. A subset of the PN states are designated as possible unsafe
states. The PN is augmented with the conditions under which those states are unsafe.
A PN reachability graph will then determine if those states can be reached during the
software execution
