The fourth tab (see figure) allows an optimization of all target variables at a time. The user enters upper and lower limits for the target variables to be optimized, and the diagram shows those variables in dependence on the control variables. The red-colored part represents the sector where all target variables are within the given limits.
Pointing with the mouse to any part of the diagram the target and control variables of the respective point are shown next to the diagram on the right. By double clicking on the graph the user can create a new process that reflects variables chosen like this.
