基于元胞自动机的混合交通流机非摩擦干扰 总被引:1,自引:0,他引:1
提出一种城市路段机非混合行驶条件下存在摩擦干扰的元胞自动机模型.该模型是在机动车NS模型的基础上引入一条摩擦减速规则,使受到自行车干扰的机动车进行减速.根据模型的规则,对不同机动车密度和非机动车密度的情况进行仿真,仿真结果基本符合实际的情况,得到机动车在干扰情况下通行能力平均下降20%左右,平均速度下降18%左右.最后,通过实际观测数据的验证,表明该模型可靠性较好. 相似文献

城市公共自行车系统由于不均匀的需求分布,需要进行自行车再分配调度,并且随着系统的使用,待维修自行车的收集和运返也成为日常运营的重要活动.本文研究考虑了自行车运返维护的静态自行车再分配问题,是一种包含正常自行车和待维修自行车的双货物路径规划问题.针对问题建立整数规划模型,提出了基于动态规划的精确算法,并根据问题特性引入两条加速规则.基于多组随机生成算例进行实验计算,并且与CPLEX进行对比,此外还针对维修车辆的数量进行了敏感性分析.计算结果验证了两条加速规则的有效性,所提动态规划算法可以有效地求解该问题. 相似文献

Representation assumes that those who govern have knowledge of those for whom they govern. It is easy to presume knowledge of the “other”, but as we know this can be based in prejudice, cultural difference, or simply misinformation or simplification. Usually our explorations of this process have focused on populations identified as disadvantaged, disempowered or somehow “non-privileged”. However, the research process outlined here has revealed previously unexplored diversity within a population commonly described as privileged suggesting that good governance requires alertness to presuming to know both the unprivileged and the privileged. The research approach outlined in this paper has used a blend of historical reappraisal and qualitative techniques focusing on a population who have been conceptualized as doubly privileged. This population focus is that of older British; post World War II male migrants in South Australia. These people have been conceptualized as privileged because they are male, and they were part of the preferred ethnic group that Australian politicians and policy makers favoured post WW2. However, review of the historical data and qualitative interviews with some of these men show that the accepted narrative of a homogenous pre-WW2 British origin population is over simplistic. The historical research suggests that the presumption that post WW2 British migrant men were coming into an homogenous, privileging environment in migrating to SA is both ahistorical and crude. Furthermore the belief that post WW2 British migrant men were ethnically homogenous is undermined by the qualitative research, that reveals that their presumed homogeneity is much more fluid and nuanced than dominant conceptualisations have allowed. The impact of core ethnicities that continue to exist and compete in Britain, the social class focus and economic commodification of migrants in the machinations of powerful players in the state of South Australia all confound homogenizing, simplistic knowing of British migrant men in this state. Generically these findings caution social researchers with regard to presuming to know so called “privileged” populations as well as presumed non-privileged groups. 相似文献

An Holistic Approach to the Management of Information Systems Development—A View Using a Soft Systems Approach and Multiple Viewpoints 总被引:1,自引:1,他引:0
Bennetts Peter D. C. Wood-Harper A. Trevor Mills Stella 《Systemic Practice and Action Research》2000,13(2):189-205
This paper argues that only a systems-based approach to information systems development is likely to cover all the recognized problem issues reported in the literature. It is then shown that software development can be characterized by the structure of the Soft Systems Methodology, so that this methodology acts as a metaphor for the process of information systems development. The structure of this methodology can be seen at lower levels of the development process, and so the model generated here is seen as recursive. Further, information systems development is seen as an unstructured business problem that can be characterized by the Multiple Viewpoint approach. The connections between this approach and the methodology are identified. Finally, the unifying link between these approaches and all forms of action research is identified. 相似文献
