| 摘 要： | 在热轧生产调度数学模型的基础上,提出一种改进的基于小生境技术的分布估计算法。采用Hebb学习规则来更新概率模型,增强了小生境之间以及整个群体间的相互学习能力。在对新种群采样时,引入了一种竞争选择机制,使得父代中的优秀个体在进化过程中得以保留,从而保证了进化持续有效的进行。为将该算法用于热轧生产调度,设计了一种新的解码方式,并采用某钢厂实际生产数据进行仿真实验,验证了算法的有效性。 |

| Abstract: | Mathematical model of hot strip rolling scheduling problem was introduced.A new improved Estimation of Distribution Algorithms(EDAs),called Niche based EDAs(NEDAs),was proposed.The Hebb learning rule was employed to update the probability distribution model,which enhanced the mutual leaning ability between niches and the population.With the purpose of keeping the efficiency and continuity of the evolution process,a competitive selection mechanism was implemented to survive the elite of the latest generation.In order to facilitate the solving of the hot strip rolling scheduling problem,a new decode method was adopted.And experiments were conducted based on practical production data.The simulation results show the effectiveness of the algorithm. |
| Keywords: | estimation of distribution algorithms niche hot strip rolling scheduling hebb rule |
