Process design algorithm

Nevertheless, in process design problems where model evaluations are frequently expensive, application of the SQP algorithm alone has provided great impetus toward solving optimization problems efficiently. Flowsheet optimization, one class of problems in this category, is discussed in the next section.

To address the ideal including environmental impact considerations into process design, Cabezas et al. [5] introduced a potential environmental impact (PEI) balance as an amendment of the Waste Reduction Algorithm [6]. However, this algorithm is simply a tool to be used to aid in evaluating the environmental friendliness of a process [7]. 

Therefore, the Kalman designed algorithm is specified by obtaining the modified Z-transform of the process pulse transfer function ot get P(z) and Q(z) and then substituting these values into equation (19). 

Walsh et al. (1995) used a simplified BREAD process model in conjunction with a parameterised uncertainty description to predict the performance. Worst-case design algorithm of Walsh (1993) was used to systematically determine the optimal operating policies that allow performance constraints to be met over a bounded set of uncertain parameters.
