“…Mu et al , using a set of 10 process variables developed a genetic algorithm which optimizes operation profit either by manipulating product quality, i.e., 4-CBA and process throughput, or by operating the process variables sequence in the proper operating order. Hong et al present a Fuzzy Adaptive Immune Algorithm. Gujarathi and Babu present a multiobjective optimization algorithm based on effect of six decision variables identified, namely, catalyst concentration, vent oxygen content, % water in solvent, feed xylene rate, temperature of reactor, and total feed rate, also to achieve the same effect of allowing the industrial operator to make the desirable improvement in the process design decisions.…”
