Fault Tree Analysis (FTA)

FTA is fault tree analysis, used for identifying causes required for a particular fault/event to take place.

This technique uses basic symbols of electronic & logic field. The Fundamental symbol used are AND & OR gate.

Truth table for AND & OR gates:

Input Output
A B AND OR
0 0 0 0
0 1 0 1
1 0 0 1
1 1 1 1

Symbols of AND & OR gates:

and or gates

The failure mode being studied is called head event.

The basic concept of this technique is to put all effecting events in a logical form.  Take a case of motor stoppage. The motor can be stopped due to following reasons:

  1. Power loss
  2. Overload
  3. Coil Damage
  4. Process interlock operated

Further power loss can occur if the incomer power supply fails & the emergency generator also fails at the same time. Over load can occur due to chocking in pipe line, or, the isolation valve is closed. Coil can damage due to over current or moisture ingress. Process interlock can be operated due to instrument malfunction or real high vibration.

The Logic tree can be built as follows:FTA

All the identified events can be given probability of failure depending upon MTBF calculated from past events. In case both events are required for resultant event to occur ie. AND gate, the probabilities are multiplied. In case, any one input can have the resultant impact ie. OR gate probabilities are added.

The FTA Analysis is done for finding out all probable faults possible. This enables us to attack on right cause for identify & eliminating the fault.

Failure mode & effect Analysis (FMEA)

An Engineering technique for system reliability improvement.
FMEA refers to a structural tool to identify potential failures at component level, the causes of these failures, and effect these failures will have on the operation of the system.

Steps:

1. Determine product & gather associated data.
2. List all the possible failure modes. This is a very important step, and should be given enough time and resources. For each failure ask how, where, when and why.
3. Calculate RPN (Risk priority No.)
4. Put all in descending order of RPN nos.
5. Development of action plan which the team deem most significant.
6. Failure with high Severity no. should be given importance even if RPN no. is low.
7. Document & report the results

Risk Priority No.:

RPN= Probability of Occurrence X Severity X Detection

Probability of Occurrence: this refers to probability of occurrence of failure
Severity: An estimate regarding the impact of this failure would have
Detection: An estimate of probability that the failure would be detected, if occurred.

FMEA

This is a Before-the-fact action, not an After-the-fact action.

Applications of FMEA:

1. Design of reliability. This is termed as DFMEA (design FMEA)
2. Quality engineering. This is to improve process and is termed as PFMEA (process FMEA).
3. To prepare maintenance strategy of installed equipment.
4. Proactive identification and elimination of potential of failures.
