生产工序约束下物流资源多矛盾目标优化调度

在车间生产工序约束下,为了实现物流资源的多矛盾目标优化调度,提出了密度自适应MOEA/D算法的调度方法。对智能车间中生产工序约束下的物流调度问题进行了分析,并建立了最小化完工时间、物流车数量和惩罚成本等多矛盾目标的优化调度模型。以MOEA/D算法为基础,设计了随邻域中染色体密度自适应变化的惩罚因子,调节了染色体多样性和算法收敛性,有效提高了算法的解集质量。将密度自适应MOEA/D算法应用于物流资源调度中并进行实验验证,结果表明:与MOEA/D算法、改进NSGA-II算法相比,密度自适应MOEA/D算法的解集质量更高、分布多样性更好。以3台物流车为例,密度自适应MOEA/D调度方案的完工时间最短,为749 min。实验结果证明了文章方法在物流资源多矛盾目标优化调度中的优越性。

社会主义社会矛盾运动新论

社会主义矛盾运动并非总是前进上升运动，它在客观上区分为优化运动和扭曲运动。矛盾优化运动是社会主义优越性充分发挥的结果，矛盾扭曲运动是社会主义缺点放大的产物。当党的路线政策正确，主体活动基本矛盾两个方面间产生协同互补效应之时，矛盾运动步入良性优化轨道；当党的指导思想发生偏差，主体活动基本矛盾两个方面间出现离异互损效应之时，矛盾运动陷于反常扭曲状态。造成主体活动两个方面间最优的协同互补效应的局面，是社会主义矛盾运动的理想目标。

Environmental Risks in China and Their Countermeasures

The 13th Five-year Plan period （2016-2020） is a crucial period for environmental protection in China and represents the last chance for the achievement of the environmental objective under the goal of building a well-off society in an all-round manner. During this period of time, China＇ s environment is confronted with the following major risks： risks of environmental quality, human health, ecological security, balanced regional development and international influence. The overall conclusion is that the tendencies of changing eco-environment are complex, problems remain outstanding, and some risks have abated while others have intensified with possible improvements in the future. Future prospects mainly depend on the intensity of actions taken. It is suggested that environmental protection strategy of＂overall optimization＂ be adopted for the 13th Five-year Plan period, i.e. environmental protection requirements should be incorporated into political, economic, social and cultural spheres, so that these areas with major influence on the natural environment will improve and transform towards an environmentally friendly direction and ultimately help achieve the objective of improving eco-environment and people＇s welfare. In order to fundamentally reverse mainstream understanding on environmental protection, it is suggested to define the ＂contradiction between environmental pressures arising from growing economic development and China ＇ s limited and fragile environmental capacity＂ as a major contradiction of Chinese society.

安保学警战时思想政治工作路径分析——以毛泽东“六有”政治局面为视角

在大型长期安保活动中,增援学警易产生安保动力缺失、能力培养不足、引发消极懈怠、滋生助长戾气、工作氛围压抑的情况甚至产生违纪违规问题。文章以"六有"政治局面为视角,通过对安保学警的思想政治环境分析原因,寻找对策,为战时学警的思想政治工作提出建议,也为相关部门组织学警参加大型安保活动提供参考。
