| Summary |
"A study of the return-on-investment (ROI) surfaces for a single reactor chemical plant (Westbrook (8)) with a discontinuous investment function confirms its unimodality in the valid region. In both cases studied, the return-on-investment surfaces rise smoothly to the adiabatic boundary from a singular flow rate below which two of the component flow are not physically realizable. The optimum is located on the adiabatic boundary. Comparison with these surfaces shows that using linear regression to obtain the parameters for an algebraic simulation of investment does not yield ROI values acceptably near the optimal. However, an heuristic approach, which assumes that minimizing the recycle heat exchanger area requires the optimal design to lie on the adiabatic boundary, was correct"--Abstract, leaf ii. |
