Values of Criteria and Limits Deterministic Method [21] Proposed Algorithm(Max-Min Pareto Optimisation)
1. Benzene output from the benzene column, in thousands of tons - criterium y1 133 134.1
2. Refined petroleum output from the benzene column in thousands of tons - criterium y2 82 82.4
3. Heavy aromatics output from the refining column, in thousands of tons - criterium y3 450 450
4. The membership function for fulfilment of the fuzzy limit «The mean octane value of the benzene must be no less than 102 – - 1.0
5. The membership function for fulfilment of the fuzzy limit «The sulphur content of the benzene must be no more than 0,00005% – - 1.0
6. The optimal values of the regime parameters for the benzene producing complex :
x1*- the raw output of the reformer in thousands of tons.
746 746
7. x2*- the temperature in the benzene column in оС; 1240 1230
8. x3*- the pressure in the benzene column in kg/cm2; 37 35
9. x4 *- the sulphur content of the raw material, %; 0.005 0.005
10. x5*- the aromatic hydrocarbon content of the raw material, %. 50 50
