Multi-criteria Compare
The Multi-criteria Compare feature allows you to prioritize projects by weighting competing priorities.
When you first click on the Multi-criteria Compare button, a new browser window opens to the tool. On the left are the top-level navigation tabs – Projects Selection, Overall Score, and Individual Metrics.
The left side of the screen is a menu that allows you to move between steps reports.
The Projects tab on the Projects Selection page is the landing screen.
Projects Selection
Start by selecting the projects you want to compare.
Contract. Choose the Contract which contains the groups with the projects to be compared.
Group. Choose the Group which contains the projects to be compared.
Comparison Start Year/Comparison End Year. Choose the period of analysis; data outside of these years will be disregarded for the analysis.
Discount Rate. Select the discount rate to be used in the analysis.
On the Metric Weighting tab, select the weights for each category of evaluation. The upper tier of weights entered must add to 100%. The bottom tier is only the relative weighting of factors within the larger Societal Benefits category. These are weighted just with integer weights, but there is no constraint on their sum.
Overall Score
The Overall Score page has two tabs, the Table tab and the Chart tab. The Table tab displays the primary results of the analysis.
Raw Metric Value. Raw values of component as calculated by TREDIS.
Scaled and Normalized. The values after normalization (which accounts for the cost of the project) and scaling (which puts the score on a continuum of scores between 0 and 100). For separate components of Societal Benefits, this is normalized and scaled relative to all the societal benefit components across all projects. For Societal Benefits row, this represents the components added then scaled among the totals.
Weight. Weights chosen in the Projects Selection screen.
Individual Score. The final score for the component. For Societal Benefits, this is scaled again to produce the total Individual Score for Societal Benefits.
The Charts tab shows scoring data as a bar graph.
The legend at right allows the user to toggle on or off components of interest, and hovering over a bar section will display a score (as in the illustration, where a label for the Vehicle Operating Cost Savings appears). For Societal Benefits, this score is further scaled to represent its final contribution to the individual score.
Individual Metrics
The individual metrics page allows you to perform tracing on the source of individual metrics. The Category dropdown allows you to choose the component of interest, "Jobs" or "Social Benefit".
Cost ($M). Total discounted project cost.
Raw Metric Value. Values taken directly from project results.
Normalized Metric value. Values after normalization (where values are divided by cost to provide per-dollar metric). For Societal Benefits, reported Normalized Metric Value has already scaled to the value of the project with the highest Normalized Societal Benefits in order to be consistent with the overall scoring process.
Scaled and Normalized Metric Value. Values after normalization and scaling (where normalized values are adjusted to a score of 0 to 100 based on the minimum and maximum of the component).
