英文摘要： Ethylene is the most fundamental plants in petrochemical process, and cracking process is the most critical unit of ethylene plant. With the diversification of hydrocarbon feedstocks and the large scale production of ethylene plant, some new problems and challenges have been brought forward to the operation optimization of the pyrolysis process. This project will focus on the uncertain cyclic operation optimization problems of ethylene cracking furnaces, which is characterized by parallel scheduling and semi-continuous operation. Based on the understanding and facilities of the cracking reaction mechanism, the following researches will be carried out, that is, the problem statement and description of the optimization of cracking furnace with uncertain operation cycle, the optimal allocation of raw materials to cracking furnaces considering multiple constrains, the multi-objective dynamic coordination of cracking furnace group. The quantitative relationship of the optimal allocation of raw materials and the efficiency of cracking furnace will be analyzed, and the dynamic optimization methods especially fit for the uncertain cyclic operation characters of ethylene cracking furnace will be carried out. Thus to provide some considerations and results from multi-evaluation indexes, which integrated pyrolysis yield, e
