蓄冷与峰谷分时电价间的关系   总被引:2,自引:0,他引:2  
制冷或空调工程中引用蓄技术是电网实现负荷移峰填谷的措施之一,而推动蓄冷技术广泛应用的有效经济手段是实行峰谷分时电价政策。本文产制冷或空调工程的费用方程,通过分析 蓄冷技术与峰谷分时电价间的内在联系,指出只有在a-b+c+d/t1〈0的条件下引用蓄冷技术才具有经济价值,它对于峰谷分时电价的确定及工程方案的决择具有非常重要的意义。  相似文献

Total Quality Management (TQM) is perhaps the leading management approach that companies employ to improve their product and service quality with the aim of improving typical measures of business performance (e.g. increased profits, increased market share, reduced costs). However, consumer perception of quality not only results from an evaluation of the intrinsic quality attributes of the product (e.g. performance, reliability, durability) but is also affected by the marketing mix (e.g. price, advertising, warranties) adopted by the company selling the product. This paper offers a first attempt at cross-functional fertilization by examining the relationships between TQM, some marketing mix variables and measures of company performance by exploring the diverse multidisciplinary literature and developing an explanatory framework, which is tested using non-parametric correlation and refined through an empirical study of Spanish manufacturing companies. The results show that the most important TQM dimensions are the system of employee relations and the use of quality management-related design tools. The results also indicate the existence of a relationship amongst price, advertising and warranties, but that these marketing variables were not related to TQM and that further research is required to include a wider definition of marketing strategy.  相似文献

根据广东省海关的统计数据,选择了四种代表性商品作为研究对象.通过同类商品相同运输模式下不同贸易方式商品单价的比较,以及同类商品相同的贸易方式下不同运输模式商品单价的比较,揭示了商品单价与运输模式选择之间的内在联系.研究表明,国际贸易商品单价是一个动态变量,而且同类商品出口单价与进口单价、海运商品和空运商品单价的对应关系也同样处在动态变化过程中.用单一的临界值来决定不同类商品在国际贸易中运输模式的选择缺乏实践的支持.  相似文献

Engineering Management programs/courses are a recent development in response to the demand from industry. This paper demonstrates that Engineering Management is an independent field of education. Background, contents, and courses of Engineering Management are reviewed, analyzed, and discussed. The Master of Science (MSc) program in Engineering Management at City University of Hong Kong is used as an example for the purpose of discussion. The information in this paper will be of use as a reference for developing/reforming courses and curricula in Engineering Management.  相似文献

The number of speeding- and drunk driving-related injuries in China surged in the years immediately preceding 2004 and then began to decline. However, the percent decrease in the number of speeding and drunk driving incidents (decrease by 22%) is not proportional to the corresponding percent decrease in number of automobile accident-related injuries (decrease by 47%) from the year 2004 to 2010 (Traffic Management Bureau, Ministry of Public Security, Annual Statistical Reports on Road Traffic Accidents). Earlier studies have established traffic violations as one of the major risks threatening road safety. In this study, we examine in greater detail two important types of traffic violation events, speeding and drunk driving, and attempt to identify significant risk factors associated with these types of traffic violations. Risk factors in several different dimensions, including driver, vehicle, road and environmental factors, are considered. We analyze the speeding (N = 11,055) and drunk driving (N = 10,035) data for the period 2006–2010 in Guangdong Province, China. These data, obtained from the Guangdong Provincial Security Department, are extracted from the Traffic Management Sector-Specific Incident Case Data Report and are the only comprehensive and official source of traffic accident data in China. Significant risk factors associating with speeding and drunk driving are identified. We find that several factors are associated with a significantly higher probability of both speeding and drunk driving, particularly male drivers, private vehicles, the lack of street lighting at night and poor visibility. The impact of other specific and unique risk factors for either speeding or drunk driving, such as hukou, road type/grades, commercial vehicles, compulsory third party insurance and vehicle safety status, also require particular attention. Legislative or regulatory measures targeting different vehicle types and/or driver groups with respect to the various driver, vehicle, road and environmental risk factors can subsequently be devised to reduce the speeding and drunk driving rates. As the country with the highest number of traffic accident fatalities in the world, applying these findings in workable legislation and enforcement to reduce speeding and drunk driving rates will save tens of thousands of lives.  相似文献

高科技产品是科技发展的产物,对发展国家经济和提高人民群众的生活水平起着重要的作用。考虑高科技产品斜坡需求和延迟补货受时间和价格影响的特点,将顾客分为价格偏好者和时间偏好者,构造了2种不同的延迟函数,建立了相应的经济订货批量模型,采用数值仿真分析了系统主要参数对高科技产品订货策略和总利润的影响。研究结果表明:需求增长因子、价格敏感因子以及资金贴现率对订货次数和服务水平的影响比其它因素大;需求增长期长度、价格偏好者比例对服务水平的影响比订货次数大;计划期长度对服务水平的影响比订货次数小。  相似文献
