通过分析钢桶的特点以及出入库频率,设计了专门的自动化立体仓库。为了尽可能地提高仓库容量,采用了重 力式货架;为了堆垛机可以连贯地执行出入库操作,将传送带布置在巷道中取代出入库台,并设计了特殊形式的货叉。 由于仓库中堆垛机周期与以往的不同,重新计算了堆垛机的工作周期。最后设计了仓库的控制管理系统并通过Flexsim 仿真验证了方案的可行性。计算和仿真结果表明:仓库的设计能够满足钢桶自动化仓储的需求。  相似文献

城市社区公共物品多主体供给是社区公共物品供给建设的发展趋势。基于五省市626份社区样本实地调查数据,深入分析城市社区公共物品多主体协同供给现状及影响主体间有效协同的制约因素。研究发现:我国城市社区公共物品多主体协同供给总体满意度较高,但是多元主体在供需匹配性、效率性、合作性等方面问题凸显。回归分析显示,业务流程关系、信息沟通反馈、主体间的互信程度对城市社区公共物品多主体协同供给具有显著正向影响,自身利益关注程度具有显著负向影响。  相似文献

随着社会经济的发展和城市功能的拓展,城市游憩用地在城市空间中的作用越来越重要,然而受制于游憩用地管理体制和规划实践滞后的局面,我国城市游憩用地研究还有待突破。通过对国内外城市游憩用地相关领域的研究综述,找到国内城市游憩用地研究的薄弱环节和可能的研究方向。梳理了目前国内外游憩用地管理的体制,归纳出了目前国内外城市游憩用地研究的5个内容:概念和内涵的探讨、理想模型的构建、城市游憩用地需求的研究、城市游憩用地指标的研究和城市游憩用地的分布规律研究。通过对比发现,国内研究与国外研究还有较大差距,尤其体现在理论构建、需求和指标研究方面。指出了国内游憩用地未来可能的4个研究方向——指标体系、游憩需求、布局规律和驱动因子。  相似文献

The paper complements Abu-Orf's theory about violent settings by setting out a theory of fear in urban planning in ordinary urban contexts around three arguments: spatialization of fear; (modernist) spatialities and the encounter and political economies of urban fear. The three theoretical arguments are used to re-frame the planning history of Chelas, an affordable housing district in Lisbon, Portugal, and debate the way fear shapes, and is shaped in turn by, planning practice. Confirming that (growing) fear in ordinary urban contexts is not just an effect of the contemporary organization of cities, the paper argues for a theorization of fear that combines global (hegemonic) and a local (discursive/contingent) perspectives in the theorization of urban fear, and advocates for the need to put fear, and its capacity to create a crisis in urban policy, at the heart of planners' agendas.  相似文献

Although the term ‘quality’ has a universal positive connotation and typically is framed by a focus on improvements, its application includes as well as excludes the access, values and world views of particular actors and interests. In this article, we highlight the relevance and implications of such ‘inherent politics’ through a case study of a widespread approach to operationalizing quality in urban green space management. We conclude that adoption of any quality model has both limiting and enabling implications for public participation and decision-making and that a critical stance is needed within both research and practice for the development of quality models that connect to values of broader societal relevance.  相似文献

Large-scale projects seem to be as popular in urban politics as they are risky in implementation. Existing research shows a certain bias towards studying projects in large metropolitan regions. The paper aims at extending the scope of research on large-scale urban projects by analysing such projects in a smaller metropolitan area. The case of the city region and country of Luxembourg shows that decision-makers in small metropolitan regions also make use of large-scale urban projects as a planning and place-making instrument. The case is also used to explore methodological approaches of examining the symbolic nature and discursive place-making dimension of planning large-scale projects, and proposes a methodological approach based on constructivist grounded theory and situational analysis of discourses.  相似文献

Much attention has recently been focused on the bankruptcy of the City of Detroit in 2013 and the reasons for the largest municipal fiscal melt down in US history. Contrary to a view gaining currency, which dismisses Detroit as the product of exceptional forces and largely calls it the architect of its own collapse, this article argues the case that Detroit conveys more general lessons for European cities struggling with decline, not least of which is the need for interventionist regional planning to avoid predictable but avoidable urban distress. The article briefly reviews the well-documented decline of the city of Detroit measured against population, economic, fiscal and image impacts. It considers five current misreadings of the reasons for Detroit's predicament and implicit signposts for European practice before concluding with an assessment of what has been hailed as the shoots of yet another possible renaissance in the originally proclaimed Renaissance City over 40 years ago.  相似文献

旅游业具有综合性和开放性两大行业特征,客观上决定了区域旅游发展必须突破城市边界,形成城市旅游网络组织,全面开展区域旅游合作。由于各城市旅游在网络组织中结构的差异性,致使其在区域内的地位与作用也不尽相同。通过对山东省城市旅游网络组织结构的分析,反映山东省城市旅游网络下各城市旅游网络结构(网络规模、密度、约束度及中心/边缘等)的差异性,并提出优化区域城市旅游网络组织结构的若干建议。  相似文献

Differentiated gender roles in adulthood are rooted in one's gender role socialization. In order to understand the persistence of gender inequalities in the domestic sphere, we need to examine the gendered patterns of children's housework time. Although researchers have identified behavior modeling as a major mechanism of gender role reproduction and characterized gender socialization as a contextually embedded process, few have investigated contextual variation in behavior modeling, particularly in non‐Western developing countries. Analyzing data from the China Family Panel Studies 2010, the author examined the differences in behavior modeling between boys and girls age 10–15 from 2‐parent families (N = 1,903) in rural and urban China. The results revealed distinctive gendered interplays in the way parental housework and employment behavior helps shape children's housework time. This analysis is a crucial illustration of how the distinctive sociocultural contexts of rural and urban China moderate the effects of housework‐behavior modeling on intergenerational gender role socialization.  相似文献
