This interactive tool uses level diagram for graphical representation of Pareto fronts and set that come from multiobjective optimization. It is a completely rebuilt of the previous tool* looking for more flexibility and interactivity with the user.
The tool allows the basic operations with level diagram and adds some new features: the possibility to change colors, shapes and sizes of each one of the points in the representation. In level diagram representation, the norm used for axes synchronization can offers different points of view about the possible solutions, then the tool has been created to makes easier the change of these norms. As a new characteristic, the tool allows the superposition of several Pareto front and set (called ‘concepts’) in order to compare them. This characteristic is quite useful when comparing several design alternatives with its corresponding Pareto solutions.
These capabilities increase the synchronization between the different plots of the level diagrams. Level diagrams with these extended capabilities give a valuable tool in decision making process.
Three examples are supplied and commented inside the scripts:
- ‘Examples_ldraw.m’ shows the basic command for drawing level diagrams and coloring, sizing and changing size of the graphical points. It also shows how to change the norm for y-axis synchronization. (screencast:
- ‘Example_comparingConcepts.m’ shows an example of Pareto front superposition. (screencast:
- ‘example_with_2_ld.m’ shows the synchronization with 2 level diagrams simultaneously, a level diagram that 2-norm and a level diagram that use Quality indicator to show dominance relationship (screencast: For details about Quality indicator see:
