中文摘要：
针对静态知识化制造环境下的航空发动机装配车间，研究了知识化制造系统自进化问题，采用滚动时域方法实现了该装配车间的周期性自进化。根据问题的特点，建立了系统在每个决策时刻的静态子问题的数学模型，提出了基于初始决策方案的滚动规则，进而给出了一种求解自进化问题的两阶段算法。针对所建立的数学模型，设计了一种具有双层结构的遗传算法（BiGA）。最后通过仿真验证了模型和算法的有效性和可行性，并分析了滚动窗口和滚动步长的大小对生产性能的影响。
英文摘要：
For an aircraft engine assembly workshop under static knowledgeable manufacturing environment,the self-evolution problem of knowledgeable manufacturing systems was studied.Roll-ing horizon method was adopted to implement the assembly workshop’s periodic self-evolution.On the basis of the characteristics of the problem,a mathematical model of the static sub-problem at each decision moment was established.A rolling rule was proposed based on the initial decision scheme, and a two-phase algorithm was given to solve the self-evolution problem.For the mathematical mod-el,a BiGA was proposed.Finally,simulation results demonstrate that the proposed model and algo-rithms are effective and feasible.The influences of the sizes of rolling window and rolling step on the production performance were also analyzed.
