Multi-duplication fault tolerant scheduling algorithm based on genetic algorithm in heterogeneous systems by Zhong-zheng HE, Chao-guang MEN, Yong-jun CHEN, Xiang LI

“…The fault-tolerant task scheduling mechanisms based on multi-duplication didn’t consider the scheduling makespan,the dependencies between tasks,the failures of the links and the longer scheduling makespan caused by the strict scheduling method in the heterogeneous distributed system.So the reliability calculation method that can involve the processor failures and the link failures was proposed firstly.Then the 0-1 integer linear program was proposed for the general scheduling problem.At last,the RAMD_TGS(reliability-aware multi-duplication task general scheduling) algorithm was proposed to solve the 0-1 integer linear program.The algorithm searched the mapped processor and the start execution time on the mapped processor for the task duplication by the evolution of the genetic algorithm.The experiments show that the RAMD_TGS algorithm can meet the reliability requirements and outperforms the existing scheduling algorithms based on the strict scheduling method in terms of scheduling makespan.The resource usages of the algorithm are also acceptable.…”

Dam Risk Identification Method Based on EAHP-EWM-TOPSIS by ZHAN Mingqiang, CHEN Bo, TIAN Jufei, HU Zelin, PAN Xinmei

“…To address the uncertainty and fuzziness of dam risk indicators, this paper proposes a dam risk identification model based on the EAHP-EWM-TOPSIS game combination model.This is to determine the subjective and objective weights of risk evaluation indicators by extension analytic hierarchy process and entropy weight method respectively.Meanwhile, the game theory is introduced to determine the optimal combination weight, and a weighted standardized decision matrix is constructed.Then, the TOPSIS method is employed to calculate the relative proximity between each risk factor and the ideal solution as the basis for ranking risk factors to identify the main risk sources of dams.The engineering example shows that the main risk factors affecting the safe service of the dams are dam seepage and cross-bank seepage, with the relative proximity of 0.712 7 and 0.855 2 respectively.The identified main risk factors are consistent with the actual engineering situation, which verifies the model effectiveness.The differentiation degree of this model is more obvious than other models, providing an effective basis for dam reinforcement and risk management.…”
