受生物启发的化工过程优化建模方法及应用研究

Chemical processes have the features of complexity, uncertainty, nonlinearity, multi-objective, multi-constraint, multi-resource coordinated with one another. Process modeling is the key technology to realize the purpose of safety production, optimal operation and advanced control. It is urgent to develop the new modeling strategy of chemical processes under uncertain environments. By going deep into investigate bio-inspired optimization algorithms, this project will explore efficient ways to track the challenging problems of chemical process modeling under uncertainties. Inspired by biological DNA, RNA，protein, and based on genetic information expression and molecular computing, the novel single-objective/ multi-objective DNA genetic algorithms will be proposed. Inspired by membrane structure and functions, and based on evolution computing and DNA computing, the novel single-objective/multi-objective membrane computing based optimization algorithms will be proposed. Both the parameter models and non- parameter models of chemical processes are established under uncertainties. The robustness and flexibility of the process modeling strategies are investigated in detail through numerical simulations. Applications in fluid catalytic cracking processes and gasoline blending processes will demonstrate the efficiency of proposed approaches. The research of this project will provide new research fields and directions for modeling of chemical processes, and offer theoretical basis of engineering applications of optimization modeling. This project has the extremely important theory significance and application value.
