东营三角洲演化特征与岩性圈闭分布规律

东营三角洲是东营凹陷古近系沙河街组沙三段的主要沉积体系之一，为一大型复合三角洲。该三角洲形成的浊积砂体岩性圈闭是东营凹陷沙三段重要的勘探目标，近几年平均每年发现的岩性油藏石油储量超过千万吨。为了给东营三角洲隐蔽油气藏进一步的勘探提供科学依据，运用高分辨率层序地层学理论和分析方法，在建立高频层序地层格架的基础上，研究东营三角洲演化过程、古构造坡折发育类型及不同期次三角洲与构造坡折的配置关系，分析这些因素对岩性圈闭形成的重要作用，认为在进积时期推进距离较远(三角洲进积作用大于加积作用)、退积时期湖泛规模较大条件下发育的三角洲朵叶体易形成具有一定规模的浊积扇．     

EVOLUTIONARY ALGORITHMS WITH PREFERENCE FOR MANUFACTURING CELLS FORMATION

Due to the combinatorial nature of cell formation problem and the characteristics of multi-objective and multi-constrain, a novel method of evolutionary algorithm with preference is proposed. The analytic hierarchy process （AHP） is adopted to determine scientifically the weights of the sub-objective functions. The satisfaction of constraints is considered as a new objective, the ratio of the population which doesn＇t satisfy all constraints is assigned as the weight of new objective. In addition, the self-adaptation of weights is applied in order to converge more easily towards the feasible domain. Therefore, both features multi-criteria and constrains are dealt with simultaneously. Finally, an example is selected from the literature to evaluate the performance of the proposed approach. The results validate the effectiveness of the proposed method in designing the manufacturing cells.

INDIRECT ACCELERATED ADAPTIVE FUZZY CONTROLLER

According to a type of normal nonlinear system, an indirect adaptive fuzzy （IAF） controller has been applied to those systems where no accurate mathematical models of the systems under control are available. To satisfy with system performance, an indirect accelerated adaptive fuzzy （IAAF） controller is proposed, and its general form is presented. The general form IAAF controller ensures necessary control criteria and system＇s global stability using Lyapunov Theorem. It has been proved that the close-loop system error converges to a small neighborhood of equilibrium point. The optimal IAAF controller is derived to guarantee the process＇s shortest settling time. Simulation results indicate the IAAF controller make the system more stable, accurate, and fast.
