关于建立地勘单位经营者评价指标体系的思考

文章认为 ,造就具有企业家精神的地勘单位经营者 ,涉及选拔经营者和建立对其激励、约束机制两个方面。这两个方面离不开对经营者的评价指标和评价方法。文章就建立评价指标体系应遵循的全面性、科学性、注重实绩、可比性四项原则进行了论述 ,提出评价指标体系应包括潜质评价指标、显质评价指标、业绩评价指标 ,并分别就其评价方法进行了论述。

A Novel Compact Cat Swarm Optimization Based on Differential Method

ABSTRACT

A compact cat swarm optimization scheme (cCSO) is proposed in this paper, which is designed to solve application domains plagued with limited memory and less-computation power, as a member of cat swarm optimization algorithms (CSO), it composes of two sub-modes, i.e., tracing and seeking modes, so it keeps the same search logic of CSO. On the other hand, cCSO inherits the main feature of compact algorithms, a normal probabilistic model is used to represent the population of solutions instead of processing an actual population, which ensures the cCSO to have the modest memory requirement. The updating vector for the probabilistic model provides a clear moving direction for cats in next step. A cat without historical position and velocity is applied in the algorithm. When the cat is in seeking mode, it employs a differential operator to update the cat’s position, which makes it possible for the cat to have multiple searching directions. Experimental results show that cCSO has pretty performance compared with respect to some population-based testing benchmarks. And it also shows superior performance in convergence rate to some compact optimization algorithms. The case study of gray image segmentation proves that it suits for solving the optimization problem by limited hardware.     

大型互联网平台扼杀式并购规制的完善与变革

互联网平台发展壮大的同时垄断问题也引起全世界反垄断执法机构的关注。尽管《反垄断法》的修订回应了公众对数字领域垄断问题的部分关切,但传统事先申报标准无法满足互联网平台反垄断执法需求,且实质性审查制度在新业态下陷入失灵,大量大型平台企业并购初创企业案件长期逃脱反垄断审查。为此,可以通过修正申报标准、完善相关市场界定、重塑反竞争评估、优先适用行为性限制条件以及构建长效监管机制来规制扼杀式并购行为。     

On regulations for 5G: Micro licensing for locally operated networks

Future 5G networks aim at providing new high-quality wireless services to meet stringent and case-specific needs of various vertical sectors beyond traditional mobile broadband offerings. 5G is expected to disrupt the mobile communication business ecosystem and open the market to drastically new sharing based network operational models. 5G technical features of network slicing and small cell deployments in higher carrier frequencies will lower the investment barrier for new entrants to deploy local radio access networks and offer vertical specific services in specific areas and allow them lease the remaining required infrastructure on demand from mobile network operators (MNO) or infrastructure vendors. To realize the full vision of 5G to benefit the society and promote competition, innovation and emergence of new services when the 5G end-to-end network spans across different stakeholders administrative domains, the existing regulations governing the mobile communication business ecosystem are being refined. This paper provides a tutorial overview on how 5G innovations impact mobile communications and reviews the regulatory elements relevant to 5G development for locally deployed networks. This paper expands the recent micro licensing model for local spectrum authorization in future 5G systems and provides guidelines for the development of the key micro licensing elements. This local micro licensing model can open the mobile market by allowing different stakeholders to deploy local small cell networks with locally issued spectrum licenses ensuring pre-defined quality guarantees for the vertical sectors’ case specific needs.

基于改进遗传算法的沥青路面再生工厂布局优化

为了帮助沥青路面再生工厂获得更好的经济与环境效益,提出一种基于改进遗传算法的布局优化方法。首先,确定再生工厂布局的约束条件,并以非物流相关性最大、物料搬运成本最低和碳排放最少作为优化目标建立工厂布局优化模型;其次,基于初始布局方案,采用实数分层编码及排列组合方法对各功能区的初始位置进行交叉互换,并根据约束条件进行筛选,得到合适的初始种群;再次,针对横坐标层与纵坐标层进行算数交叉,变异时坐标层采用多点变异,放置方式层采用单点变异,并引入模拟退火算子;最后,以某再生工厂为例对改进算法进行验证。结果表明：改进后的遗传算法迭代次数较传统遗传算法减少34次,目标函数值较文献中遗传算法减小0.009 9,提高了算法的寻优能力;优化后的方案每日物料搬运成本减少14 468.85元,碳排放减少30.59 kg,验证了方法的有效性。研究中所提出的优化方法效率较高,可为沥青路面再生工厂的建设提供技术支持。

The distinction between commercial and non-commercial bus services in Germany: Given by nature?

German public transport services by bus are characterized by a regulatory framework that distinguishes between commercial and non-commercial services. Contrary to the apparent views of legislators, this paper shows that costs and revenues are not the only parameters determining whether or not operators are able to provide services in a commercially viable way.Apart from the local characteristics of the specific service, we show that the classification of services as commercial versus non-commercial is determined in large part by the public transport authorities that set minimum quality standards to be provided by operators. Our analysis shows that the authorities awarding the contracts in some cases affect market organization significantly depending on how they make use of this power. Furthermore, market organization differs substantially with respect to the awarding structure and the contractual relationships, thus creating a challenge for operators and authorities in an embryonic market.
