Effective SCC scheduling algorithms can help to enhance productivity, and thus make significant monetary savings. This paper develops an Improved Artificial Bee Colony(IABC) algorithm for the SCC scheduling. In the proposed IABC, charge permutation is employed to represent the solutions. In the population initialization, several solutions with certain quality are produced by a heuristic while others are generated randomly. Two variable neighborhood search neighborhood operators are devised to generate new high-quality solutions for the employed bee and onlooker bee phases, respectively. Meanwhile, in order to enhance the exploitation ability, a control parameter is introduced to conduct the search of onlooker bee phase. Moreover, to enhance the exploration ability,the new generated solutions are accepted with a control acceptance criterion. In the scout bee phase, the solution corresponding to a scout bee is updated by performing three swap operators and three insert operators with equal probability. Computational comparisons against several recent algorithms and a state-of-the-art SCC scheduling algorithm have demonstrated the strength and superiority of the IABC.展开更多

The external conditions are analyzed based on the construction of SWOT strategic matrix, found the advantages and disadvantages of the reform process of the integration of urban and rural subsistence allowances system in coexist, opportunities outweigh the challenges, so China＇s overall urban and rural integration construction is feasible.展开更多

As a prominent theorist in the field of democracy studies, David Held, by integrating the principle of autonomy in the model of constitutional democracy with the principle of participation in the model of participatory democracy, introduces a novel composition named ＂cosmopolitan democracy＂ that is a conception of democratic legal relations. Held is the first man who seeks to investigate democracy separated from the ideological models in relation to general human rights and identifies main areas of power in human life. He considers totally seven sets of rights necessarily enabling people to enjoy a free and equal participation in setting their communities. These rights include： right to health, welfare rights, cultural rights, civil rights, economic rights, political rights, and the right to enjoy a peaceful livelihood. Held＇s ultimate desire is to realize ideals of cosmopolitan democracy model in the global sphere, beyond the lessons of the West and the East. Through rethinking the theoretical and practical frameworks of this theory in today＇s world, the current paper seeks to study its role in reproducing democratic realism so that it would prepare the ground for the global consensus far from the ideal models.展开更多
