How To Build A Fault Tree

Today’s topic: “How To Draw Fault Tree In Excel“. Based on the assumptions and deductive approach of risk management, fault tree analysis is a very useful and comprehensive approach. This analysis is based on a layout in which you can visualize possible failures and a deductive way to approach their maxim reason.

  1. A fault-tree enables you to closely monitor and assess the reasons for a possible failure, factors arising this particular situation and steps. So included in eradicating this failure. It organizes all low potential ends in the form of a branched tree and you can instantly see all associated risk points to avoid any obstruction.
  2. Under the Fault Tree Analysis section, choose from a number of modern and professional templates to design your high-quality fault tree analysis diagram. Once you have opened a template in the Edraw Max online editor, you’ll have the editing tools and functions to translate the template to your fault tree analysis diagram.

Fault Tree Diagram (FTD) FTDs are analytical block diagrams that demonstrate the phase of a system (top event) in regards to the phases of its elements (basic events). Similar to RBDs, FTDs are a graphical design approach, and thus offer a substitute to RBDs. An RBD may be converted to a success tree or a fault tree depending on how the RBD is defined. A success tree may then be converted to a fault tree or vice versa by applying de Morgan's theorem. To evaluate an RBD, closed form solutions are available when blocks or components have statistical independence.

This analysis is highly useful and recommended in almost all kinds of projects such as construction projects, aerospace projects, software development etc.

Using this approach, a structured diagram is constructed for the visual imposition of different steps and procedures, leading to possible risks and failure during a state of working.

By analyzing associated causes and reasons, a manager, supervisor or planner can seek some other ways to complete the task which may avoid possible threats and risky approaches.

You can even draw fault tree on MS Excel which is even much easier to use and understand. There is a descriptive tutorial here which you can read and understand how you can use various features and options of Excel to complete this draft.

Constructer Fault Tree in Excel

Before we tell you how to construct a tree in Excel, you should thoroughly understand the application and utilization of this tree diagram in risk assessment and threat management.

You can arrange both expected and occurred failures in this diagram along with their possible reasons and factors which might generate attractive obstructions in this process.

We have listed a couple of points here, demonstrating a shorthand tutorial for constructing this tree. Take a look on the points below;

List down all the failures, faults and risks highlighted

Tree

Draw a column and list all deductive reasons of failure

With a comparison, match least abruptive and unstable approach

Take all stages of a project and organize them step by step

Associate risks of each phase and possible reasons or drawbacks as well

Using Excel spreadsheets, specify assessment and evaluation functions

Instruct the spreadsheet to place certain entries into risk full sections when below certain value limit

You can find the more detailed tutorial for a complex architecture of Excel templates in case you need.

Benefits of Fault Tree

In modern project management, risk assessment and risk management are of core importance. No project can be considered successful unless you remove underlying threats and risks.

A fault-tree enables you to closely monitor and assess the reasons for a possible failure, factors arising this particular situation and steps.

So included in eradicating this failure. It organizes all low potential ends in the form of a branched tree and you can instantly see all associated risk points to avoid any obstruction.

These are certain benefits of fault tree which save your resources and efforts, providing a conjugate basis of success in every dimension.

The failure of an item in a system is often caused by the failure of other items. Fault Tree Analysis, or FTA, provides a method of breaking down such chains of failures, with a key addition for identifying combinations of faults that cause other faults. Fault Tree Analysis Diagrams (or negative analytic trees) are logic block diagrams that display the state of a system (top event) in terms of the states of its components (basic events). ConceptDraw DIAGRAM allows you to create professional FTA Diagrams using the Fault Tree Analysis Diagrams solution.

  1. Open a ConceptDraw DIAGRAM new document and select the Fault Tree Analysis Diagrams library.
  2. Add the proper FTD elements to the diagram by dragging them from the library to the document page.
  3. The Fault Tree diagram should be started with the Event symbol for top-level failure event.
  4. Use the OR gate symbol to the output event occurs if at least one of the input events occurs.
  5. The Basic event symbol is used for event that does not have any contributory events.
  6. An AND gate symbol means the output event occurs if all input events occur.
  7. Use the Exclusive OR gate symbol to the output event occurs if exactly one input event occurs.
  8. Next, you need to connect the objects. To do this, select the neighbor objects and click the Chain Connection button.
  9. Change objects' appiarence using the Format panel options.
  10. To add text to an object, select it, and then start typing. When you are finished, click outside the object.
  11. To distribute objects at regular intervals, select the objects, and then, on the Arrange&Size panel, pick a needed option from the Align and Distribute section.
  12. To align objects horizontally or vertically, select the objects you want to align, then, on the Arrange&Size panel, select the proper option from the drop-down menu.
