地下停车库火灾风险分析

分析了地下停车库的火灾特点,并从停车库的火灾规模、发生轰燃的烟气条件、释放辐射热的大小、相邻汽车被引燃的临界条件和自动喷水系统的动作时间等几方面对停车库潜在的火灾危险性进行了探讨。以某地下一层停车库为例,对其火灾风险进行了具体评价。     

基于火灾风险分析的消防力量优化布局

分析了我国目前消防力量布局存在的问题,从当前有限消防经费和现有的城市布局出发,提出了依据风险来优化消防力量布局的观点和方法,以最大限度的提高消防部队的灭火和抢险救援能力。     

基于层次分析法的化工企业火灾风险评估研究

化工企业火灾风险评估对于化工生产至关重要。针对化工行业的火灾风险,结合层次分析法和模糊识别模式的优点,提出了基于层次分析—模糊识别的综合评价方法,并通过实例评估证明了这种评价方法行之有效。     

The impact of component commonality on composite assembly policies

Assemble in Advance (AIA) policy reduces assembly cost due to advance planning, while Assemble to Order (ATO) policy eliminates assembly of excessive (more than demanded) units. The tradeoffs between the two policies have been studied in the past for single product environments. Moreover, it was shown that it is beneficial to employ AIA and ATO simultaneously. In this article, we study the employment of such a composite assembly policy in a multiproduct environment with component commonality. When common components are used, ATO may also enable us to benefit from the risk pooling effect. We provide important managerial insights such as: the multiperiod problem is myopic and changes in inventory levels due to the use of common components, and demonstrate the potential profit increase compared to other policies.© 2007 Wiley Periodicals, Inc.

“法条竞合”若干问题研究

"法条竞合"在我国刑事立法中普遍存在,其理论比较复杂.法条竞合的概念与种类、法律性质以及法条竞合的适用原则等问题,目前在我国刑法理论界尚无统一定论.理论上对这些问题进行深入研究、探讨,有助于在司法实践中准确选择适用法条.

广义抽象协调类和广义合一原理

协调性是数理逻辑中最基本的语法概念之一。Ｓｍｕｌｙａｎ提出了抽象协调类概念，并证明了相应的Ｓｍｕｌｙａｎ合一原理。通过考察协调合式公式集类所具有的种种性质，本文将抽象协调类概念推广至最一般的形式——广义抽象协调类，并证明了相应的广义合一原理。这一结果可以用于证明一阶逻辑形式系统和我们所提出的广义反驳方法的完备性。     

标准型方案与链型方案的转换

在考虑标准型方案与链型方案抽查特性曲线基本一致的前提下,研究了标准型方案与链型方案样本量之间的差异,指出在同样的辨别力条件下,链型方案可比标准型方案节省大量的样本。在生成等效方案的过程中,本文利用求累积和搜索法,较好地解决了大样本方案生成的计算问题。     

A componentwise index of service measurement in multi‐component systems

In this paper we present a componentwise delay measure for estimating and improving the expected delays experienced by customers in a multi‐component inventory/assembly system. We show that this measure is easily computed. Further, in an environment where the performance of each of the item delays could be improved with investment, we present a solution that aims to minimize this measure and, in effect, minimizes the average waiting time experienced by customers. © 2002 Wiley Periodicals, Inc.
