Decision Tree Analysis

Decision trees are widely used in operations research. It is mostly applied in decision analysis in order to help and identify that strategy that most likely may lead to reaching a goal. It is also known as a popular tool in machine learning, thus it worth knowing about it from this article.

The ConceptDraw DIAGRAM diagramming and drawing software is the one that can help with creating the needed drawing, including a decision tree. Making decision tree analysis, it is always easy to make the needed matrix as there are plenty of pre-made templates to be used.

Decision tree

"A decision tree is a decision support tool that uses a tree-like graph or model of decisions and their possible consequences, including chance event outcomes, resource costs, and utility. It is one way to display an algorithm.
Decision trees are commonly used in operations research, specifically in decision analysis, to help identify a strategy most likely to reach a goal. ...
A decision tree is a flowchart-like structure in which internal node represents test on an attribute, each branch represents outcome of test and each leaf node represents class label (decision taken after computing all attributes). A path from root to leaf represents classification rules.
In decision analysis a decision tree and the closely related influence diagram is used as a visual and analytical decision support tool, where the expected values (or expected utility) of competing alternatives are calculated.
A decision tree consists of 3 types of nodes:
(1) Decision nodes - commonly represented by squares.
(2) Chance nodes - represented by circles.
(3) End nodes - represented by triangles.
Decision trees are commonly used in operations research, specifically in decision analysis, to help identify a strategy most likely to reach a goal." [Decision tree. Wikipedia]
The marketing diagram example "Decision tree" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Marketing Diagrams solution from the Marketing area of ConceptDraw Solution Park.

Influence Diagram Software

Influence diagram (ID) is a graphical and mathematical representation of the decision. Influence diagrams are widely used in the decision analysis and in the game theory. They are the alternative to the decision tree. The influence diagram gives to analyst the high-level conceptual view that it can use to build the detailed quantitative model. This sample shows the Influence diagram. It is a directed acyclic graph with three types of nodes: Decision node is drawn as a rectangle, Uncertainty node is drawn as an oval, Value node is drawn as an octagon. The nodes are connected with arcs.

Create Flow Chart on Mac

A Flowchart is a commonly used type of chart that describes an algorithm, process or workflow. It applies the boxes of various kinds to represent the steps and connects them with arrows showing their order. The Flowcharts help to understand the processes, visualize the process steps, and effectively find the flaws and bottlenecks. They are widely used in various fields for analyzing, documenting, designing, and managing simple and complex processes and programs, for representing process operations and problems' solution models. There are many types of Flowcharts, such as Cross-Functional Flowcharts, Data Flow Diagrams, Swimlane Flowcharts, Workflow Diagrams, Business Process Diagrams, Process Flowcharts, etc. ConceptDraw DIAGRAM is a powerful diagram software used to create Flow chart on Mac and Windows without efforts.
