D-Sight Web 3.4.8: Release Announcement

Stability Intervals and Utility Functions

We are happy to announce a new release of D-Sight Web containing some pretty awaited features. We'll include in this presentation some new features that were included in prior versions as well but didn't benefit from a complete presentation. Keep on reading to learn more about what we have included in the latest releases of D-Sight Web:

• Stability Intervals Charts (3.4.7)
• Score Evolution and Best Alternative Prediction (3.4.8)
• Create Utility Function Graphically (3.4.8)
• Sorting and Filtering Tables (3.4.6)

Stability Intervals Charts

Stability intervals (i.e. the intervals in which the best alternative remains the best) used to be simply offered as a table. While all the information was there, it is easier to visualize this information in a chart. We have therefore added one, highlighting the current weights of the different criteria and the ranges in which each weight could be changed without affecting the first ranked alternative.

Score Evolution

To continue the work done with the stability intervals, we have included another chart allowing to identify for each criterion (or category), how the ranking would evolve based on the relative weight of the criterion. In other words, this chart allows to see immediately the preferred alternative for each possible value of the weight.

This information could previously be computed from the simulation panel in the Ranking Chart page. But this tool makes it easier to get the complete picture of the impact that a change of weight might have.

Create Utility Function Graphically

We made it easier to define utility functions. It is now possible to define the function purely graphically and to refine it manually if needed. To add points to a function, simply do a left click on the graph. Move the points by dragging and dropping them or remove them with a right click.

It is of course still possible to update the values manually in order to define some points more precisely. And in case you define your functions after evaluations have been introduced, the range of the function will be automatically adjusted.

Sorting and Filtering Tables

When a project contains many alternatives and / or criteria, it might be cumbersome to find your input again in the different tables. We have therefore introduced a simple sorting and filtering system for all tables in the application.

Simply click on a column header to sort the column or enter data in the search box to filter the different inputs of the table and only display the ones you are interested in.
