# 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.

## 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.

## Types of Flowcharts

A Flowchart is a graphically representation of the process, algorithm or the step-by-step solution of the problem. There are ten types of Flowcharts. Using the Flowcharts solution from the Diagrams area of ConceptDraw Solution Park you can easy and quickly design the Flowchart of any of these types.

## Pyramid Diagram and Pyramid Chart

Pyramid Diagram is very useful to illustrate the foundation-based relationships. ConceptDraw PRO, a business charting software, includes some build-in symbols for designer to draw all kind of the pyramid diagrams.

## COM and OLE Diagram

The vector stencils library COM and OLE from the solution Software Engineering contains 15 symbols of the COM and OLE objects for ConceptDraw PRO diagramming and vector drawing software. The Software Engineering solution is contained in the Software Development area of ConceptDraw Solution Park.

"An influence diagram (ID) (also called a relevance diagram, decision diagram or a decision network) is a compact graphical and mathematical representation of a decision situation. It is a generalization of a Bayesian network, in which not only probabilistic inference problems but also decision making problems (following the maximum expected utility criterion) can be modeled and solved.
ID was first developed in the mid-1970s by decision analysts with an intuitive semantic that is easy to understand. It is now adopted widely and becoming an alternative to the decision tree which typically suffers from exponential growth in number of branches with each variable modeled. ID is directly applicable in team decision analysis, since it allows incomplete sharing of information among team members to be modeled and solved explicitly. Extensions of ID also find their use in game theory as an alternative representation of the game tree." [Influence diagram. Wikipedia]
The example "Influence diagram" was designed using ConceptDraw software extended with Decision Making solution from Management area of ConceptDraw Solution Park.

## 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.

## SDL Diagram

Specification and Description Language (SDL) is used for creating the object-oriented diagrams, visualizing the processes of the state machines for the systems of communication, telecommunication, automotive, aviation and medical industries. SDL is a specification language for creating specifications, descriptions of the behavior, data, and inheritance for real-time systems.
This sample shows the SDL Diagram of the process game.

## 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).
