Problem Statement and Key Features

First, we discuss the problem statements and key features of the learning architecture that are specific to complex systems. This is followed by a brief presentation of the search procedures that are used to build a final solution. The section ends with a summary of the application of the learning architecture to the analysis of a Kraft pulp mill. 

Remark 1 As can be seen in Figure 8.20, the above problem statement corresponds to the simultaneous consideration of the second and third rectangle inside the loop of the HRAT optimization. The key feature is that we do not need to partition the HEN problem into subnetworks based on the location of its pinch point(s). Instead, we postulate all possible matches that may take place and optimize simultaneously for the selection of matches and their heat loads, as well as the minimum investment cost network structure,...
