What is the event tree?

The event tree is part of certain analytical methodologies. It is basically a concept, often drawn as a diagram that shows a chain of causes and effects for a number of events. The event graph of an event or model can be effective in displaying the probability of results or conditions for a complex procedure.

It is often said that an event tree uses "boole" values. The Boolean value is a dialectical representation such as "True or False" where one of two conditions is displayed. Boolean values ​​often come into a game where an event or condition is either true or false for a particular part of the diagram. This event is divided into possible results. Each result is his own event, with other results arising from it. The final result is that the tree branch until various final results appear at the bottom or at the end of the tree.

As a simple example, a tree tree could be drawn by the root event was a fire in the building. The first step in the tree can be fromAsking if fire is detected. If the answer is "no", the result is that the building is destroyed. However, the answer "yes" leads to another question in the tree whether or not the sprinkler system. Each step in the tree leads to a binary question, with only one branch outlining a sequence in which all steps are successful.

Some events include probabilities for each branch. With the probability, engineers can perform a large amount of predictive problems of problems that can help avoid or solve problems. With the same basic process, the computer can also effectively model the situation and point out the most likely causes of the result.

Event tree can be part of a software package or other analytical tool in many different fields. The best use of events trees is in scientific fields such as laboratory analysis for pharmaceutical or other testing. They can also be useful in fields such as retail or production where it would out of thisLogistics or market research could benefit about the type of analysis. Another use for events trees is in the product research. For example, in a motor vehicle industry, an event tree could be useful in displaying or even predicting specific types of vehicle failures.

Another distinguishing feature of different trees of events is in their appropriate formats. They can be drawn on paper during the presentation. Trees on web events can also be useful for presentations, but are often processed into an algorithmic interface or other design software for analytical or predictive modeling.
