APPLICATION OF GENETIC ALGORITHMS BASED ON INTELLIGENT MULTI-AGENT FOR OPTIMIZATION OF EQUIPMENT OF ISOMERIZATION OF XYLENE
Genetic algorithms(GA)are used more and more wide in the optimization of complicated, non-linear questions in the chemical industries. In the paper,a multi-Agent system which includes two kinds of Agents:O-Agent and A-Agent is built.There are a number of O-Agents in the system,and their function is equal to the seeds of evolution,but there is only one A-Agent.The A-Agent is in charge of the work of evolution.It monitors and controls the GA evolution procedure. These two kinds of Agents can exchange the useful information which can represent the current situation of evolution. By means of the limit of life of these two kinds of Agents,the system can avoid prematureness and at the same time can speed up convergence.The genetic algorithms based on Intelligent Agent (M-Agent-GA) improves greatly the feature of standard GA(SGA), especially in the optimization of complicated questions. It was used in the optimization of the equipment of xylene isomerization and the result was good.
