A High-Order Spatiotemporal Precision-Matching Taylor–Li Scheme for Time-Dependent Problems

Advances in Atmospheric Sciences 2017年第12期34卷 1461-1471页

作者： pengfei wang Center for Monsoon System Research Institute of Atmospheric PhysicsChinese Academy of SciencesBeijing 100190China State Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics Institute of Atmospheric PhysicsChinese Academy of SciencesBeijing 100029China

Based on the Taylor series method and Li’s spatial differential method, a high-order hybrid Taylor–Li scheme is *** results of a linear advection equation indicate that, using the initial values of the square-wave type, a result with thirdorder accuracy occurs. However, using initial values associated with the Gaussian function type, a result with very high precision appears. The study demonstrates that, when the order of the time integral is more than three, the corresponding optimal spatial difference order could be higher than six. The results indicate that the reason for why there is no improvement related to an order of spatial difference above six is the use of a time integral scheme that is not high enough. The author also proposes a recursive differential method to improve the Taylor–Li scheme’s computation speed. A more rapid and highprecision program than direct computation of the high-order space differential item is employed, and the computation speed is dramatically boosted. Based on a multiple-precision library, the ultrahigh-order Taylor–Li scheme can be used to solve the advection equation and Burgers’ equation.

An Improved Biogeography-Based Optimization Algorithm for Blocking Flow Shop Scheduling Problem

引用

Chinese Journal of Electronics 2018年第2期27卷 351-358页

作者： LIU Shufen wang pengfei ZHANG Jiachen College of Computer Science and Technology Jilin University

To solve the blocking flow shop scheduling with maximum completion time(i.e. makespan) criterion,we proposed an Improved biogeography-based optimization algorithm(IBBO). The framework of basic BBO algorithm is used in the IBBO algorithm, and the introduction of the NEH algorithm make IBBO algorithm with certain quality and diversity. The migration operation based on the insert rules and the mutation operation based on swap rules are presented to avoid the occurrence of illegal solution of the blocking flow shop problem. An insertneighborhood search algorithm was used to strengthen the local search ability of the IBBO. The computational results show the effectiveness of the proposed IBBO algorithm in solving the blocking flow shop scheduling with maximum completion time criterion.

An Effective Biogeography-Based Optimization Algorithm for Flow Shop Scheduling with Intermediate Buffers

引用

Chinese Journal of Electronics 2018年第6期27卷 1141-1150页

作者： LIU Shufen wang pengfei YAO Zhilin College of Computer Science and Technology Jilin University

This paper proposes an Effective biogeography-based optimization(EBBO) algorithm for solving the flow shop scheduling problem with intermediate buffers to minimize the Total flow time(TFT). Discrete job permutations are used to represent individuals in the EBBO so the discrete problem can be solved directly. The NEH heuristic and NEH-WPT heuristic are used for population initialization to guarantee the diversity of the solution. Migration and mutation rates are improved to accelerate the search process. An improved migration operation using a two-points method and mutation operation using inverse rules are developed to prevent illegal solutions. A new local search algorithm is proposed for embedding into the EBBO algorithm to enhance local search *** simulations and comparisons demonstrated the superiority of the proposed EBBO algorithm in solving the flow shop scheduling problem with intermediate buffers with the TFT criterion.
