Building Excel-linked Decision Models in DPL's Influence Diagram-focused Mode:
Videos 1-6
The six videos below are a cumulative set of DPL Software Tutorial Videos in which I provide step-by-step instructions that will help you build, refine, and analyze a probabilistic decision model within a Influence Diagram-focused mode in DPL. The decision model is linked to an Excel cash flow spreadsheet. The spreadsheet used in the tutorial is called BroadswordPro.xlsx and is set up to analyze a New Product Development opportunity.
If you'd like to work through the following video tutorials with DPL you can download the BroadswordPro.xlsx spreadsheet using the link below:

Building Excel-linked Decision Models in DPL's Influence Diagram-focused Model: Video #1
Creating a Deterministic Model from Excel
This video provides a brief overview of the spreadsheet used in the tutorial and shows how to start building a deterministic model in DPL's Influence Diagram from an Excel Cash Flow spreadsheet.
Building Excel-linked Decision Models in DPL: Video #2
Adding Influence Arcs to the Model and Running a Preliminary Analysis
This video shows you how to generate arcs for a decision model. It introduces the various DPL Node Types used within the series and provides an overview of the Node Definition dialog. Near the end a preliminary analysis is run to check Excel links.
Building Excel-linked Decision Models in DPL: Video #3
Conducting Sensitivity Analysis and Introducing Probabilities
In this video I conduct a sensitivity analysis in the form of a value tornado in order to see which variable have the greatest impact on my objective. I model the variables found to have the most impact (i.e. at the top of the tornado) probabilistically by changing them from value nodes to discrete chance nodes.
Building Excel-linked Decision Models in DPL: Video #4
Adding a Decision and Running a Decision Analysis to Produce Results
In this video I add a decision to the probabilistic model and run a decision analysis in order to produce two of DPL's fundamental outputs -- the Policy Tree™ and Risk Profile. Each output is examined and explained.
Building Excel-linked Decision Models in DPL: Video #5
Adding Conditioning to a Probabilistic Model
In this video I introduce value-wise conditioning to the probabilistic model. A Market Test variable is added -- the results for which will condition the values of the Market Share node.
Building Excel-linked Decision Models in DPL: Video #6
Adding a Downstream Decision to the Model
In this video I add an explicit Launch decision to the model after I learn about the outcome of the Market Test uncertainty. This is referred to as a "Downstream Decision". I then analyze the model to see if the flexibility of this exit option adds value to the project.
Building Excel-linked Decision Models in DPL's Decision Tree-focused Mode, Videos 1-3
The three videos below are a cumulative set of DPL Software Tutorial Videos in which I provide step-by-step instructions that will help you build and analyze a decision model within a Decision Tree-focused mode in DPL. The decision model will be linked to an Excel cash flow spreadsheet. The spreadsheet used in the tutorial is called Capacity Planning.xlsx and is set up to analyze a manufacturing capacity expansion decision-problem.
If you'd like to work through the following video tutorials with DPL you can download the Capacity Planning.xlsx spreadsheet using the link below:

Building Excel-linked Decision Models in DPL's Decision Tree-focused Model: Video #1
This first video in the series provides a brief introduction to the problem after which an appropriate decision frame is established.
Building Excel-linked Decision Models in DPL's Decision Tree-focused Model: Video #2
Within the second video decision and chance events are added to the decision tree and linked to the Excel spreadsheet.
Building Excel-linked Decision Models in DPL's Decision Tree-focused Model: Video #3
This is the third and final video in a series that shows you the steps to building an Excel-linked decision analysis model within a Decision Tree-focused mode in DPL. The simple example model built within the series is a manufacturing capacity expansion decision. In this video I introduce asymmetry to the decision tree and run an analysis to find out what the optimal decision policy is.
