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 PRO 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.

How to Draw a Decision-Making Diagram

The Decision-Making solution provides ConceptDraw PRO users with vector libraries, containing a full set of flowchart symbols. Also, it offers a number of templates and samples, making short work of creating a graphical view of decision-making processes.

Decision Making

The Decision Making solution offers the set of professionally developed examples, powerful drawing tools and a wide range of libraries with specific ready-made vector decision icons, decision pictograms, decision flowchart elements, decision tree icons, decision signs arrows, and callouts, allowing the decision maker (even without drawing and design skills) to easily construct Decision diagrams, Business decision maps, Decision flowcharts, Decision trees, Decision matrix, T Chart, Influence diagrams, which are powerful in questions of decision making, holding decision tree analysis and Analytic Hierarchy Process (AHP), visual decomposition the decision problem into hierarchy of easily comprehensible sub-problems and solving them without any efforts.

"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.

Fault Tree Diagram

ConceptDraw PRO diagramming and vector drawing software offers the Fault Tree Analysis Diagrams Solution from the Industrial Engineering Area of ConceptDraw Solution Park for quick and easy creating the Fault Tree Diagram of any degree of detailing.

Decision Making

Decision Making - ConceptDraw Office suite provides visual tools that are given support on the stage of the decision making. The Seven Management and Planning Tools is a set for such diagrams: Affinity Diagram, Relations Diagram, Prioritization Matrix, Root Cause Tree Diagram, Involvement Matrix, PERT Chart, Risk Diagram (PDPC).

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.

PDPC

ConceptDraw PRO extended with Seven Management and Planning Tools Solution from the Management Area of ConceptDraw Solution Park is the best software for drawing all types of diagrams from the Seven Management and Planning Tools: Affinity Diagram, Relations Diagram, Prioritization Matrix, Root Cause Analysis Tree Diagram, Involvement Matrix, PERT Chart, and Risk Diagram (PDPC).

Influence Diagram

This sample shows the Influence Diagram. It was created in ConceptDraw PRO diagramming and vector drawing software using the Basic Diagramming Solution from the Universal Diagramming area of ConceptDraw Solution Park. Influence diagram represents the directed acyclic graph with three types of nodes and three types of arcs that connect the nodes. Decision node is drawn as a rectangle, Uncertainty node is drawn as an oval, Value node is drawn as an octagon.

Cause and Effect Analysis

Cause and Effect Analysis - The Seven Management and Planning Tools is a tool for Cause and Effect Analysis that allows users to analyze the root causes for factors that influenced the problem. This diagram is constructed separately for each highly prioritized factor. The Diagram is then used for further formulation of potential actions.
