摘要：

The paper presents an integrated procedure for the detailed design of chemical processes and the simultaneous selection of which processes should be built. The study is particularly concerned with a stream of investment which is expected to continue into the future such that the investing organisation has defined credit limits throughout the period under consideration. We have developed a two-tier optimisation procedure whereby the detailed engineering optimisation of the individual projects is performed using a modified Net Present Worth criterion. This criterion is related to overall company goals by a novel non-linear programming package that also handles the portfolio selection problem. A number of examples illustrate that the procedure is computationally efficient and that the resulting integrated design strategy is significantly better than strategies developed by previously published procedures of more restricted application. © 1979.
