时间限定条件下突发事故资源调度方案

面对数量较多需要及时处理的突发事故,为了满足最短应急时间限制,最低应急资源数和最少的出救点等目标,在事故应急方案选择时给出一个反映决策者对时间和费用偏好的折中方案十分必要.从实际应用出发,运用模糊优化方法研究时间与资源限制条件下的多出救点组合模型求解问题.给出了限制期条件下,应急时间最短的资源调度方法以及限制期条件下出救点数目最少的应急模型,从理论上证明了模型求解方法的正确性.在给定限制期条件下,救援网络中最优路线的求解,即通过分析得出超时风险最小的出救路径,并求出了应急路径的可信度.通过算例说明该计算方法的具体应用,为突发事故处理资源调度的智能化提供参考.     

Emerging design strategies in sustainable production and consumption of textiles and clothing

This study contributes to current knowledge of sustainability in textile and clothing production and consumption. When the textile and clothing industry aims to promote sustainability, the main change factors have been linked to eco-materials and ethical issues in production. At present, however, business models are mainly linked with a large volume of sales and production. Although industrial development has moved toward smaller environmental impact, production as well as consumption has increased to levels where the benefits of technological development are reduced. A change is thus needed to reach a systemic transformation, not only in production but also in consumption. The aim of this paper is to open up the discussion on opportunities for radical change in this industry. The paper presents ways to rethink and redesign business in the textile and clothing field by offering an overview on several design strategies that exist today in niche markets. Furthermore we evaluate how interested consumers are in these design strategies and discuss the opportunities these design approaches offer to sustainable development through new value creation.     

A mathematical programming tool for LCI-based product design and case study for a carpet product

Products are produced by a series of energy-intensive transformations of raw materials such as crude oil. The life cycle inventory (LCI) of mass and energy usage in these supply chains is one measure of overall environmental performance. In this paper, we present a methodology to examine the life cycle choices available for a product and optimize these choices based on criteria derived from mass and energy efficiency. A two-phase framework for production path construction followed by optimal path selection was developed. This framework can be applied to improve the overall LCI energy characteristic of a product when there are different production and recycling options for different product constituents. The scope of the life cycle is from raw material extraction through the production system and does not include the use and disposal phases. The approach is illustrated in a case study of the EcoWorx™ carpet system of Shaw Industries, which includes the inclusion of several recycled material options.

Perspectives on policy framework for trans-boundary water quality management in China

In river basins that cross jurisdictional boundaries, water quality degradation has become a crucial problem and results in intensive competition among water users, especially in developing countries. Under this situation, implementing water quality management and control across jurisdictional boundaries can strengthen watershed pollution controls, and prevent pollution from being passed on and promote active pollution control within the related jurisdictional regions. This study examined the limitations of the current trans-boundary water quality management system in China and reviewed the planning and implementation of two pilot integrated trans-boundary water management systems established in the Jiangsu and Zhejiang provinces. Based on our findings, we proposed a new policy framework for trans-boundary water quality management. As a first step toward integrated watershed management in China, this policy framework can help assess the actual water pollution status of various regions and serve as a basis for an integrated watershed management system. The framework can be easily applied in other countries with trans-boundary water pollution issues, particularly in the context of developing countries.     

外挂式声屏障

声屏障作为噪声污染治理的主要措施之一,已广泛应用于公路、铁路、市政等多种领域。传统声屏障安装方式存在一些安全隐患,针对这些安全隐患,我公司开发出外挂式声屏障。外挂式声屏障改变传统的声屏障板插接在H钢立柱内的安装方式,声屏障板安装在立柱的外侧,并且声屏障板长度可以达到6~10米,每块声屏障板有3~5个固定件固定在立柱上,不会由于某个固定件损坏产生安全问题。外挂式声屏障既保证了声屏障系统的安全,又达到了安装方便、美观大方的特点,将会在声屏障领域的得到广泛应用。
