An optimization-based vulnerability and risk analysis approach for supporting air and waste management under multiple umcertainties

大气和废物管理系统具有多个不确定参数及其相互关系，具有多个不确定性，与之相关的决策问题具有交互、动态、多目标等特点。这导致在各种系统条件和政策情景下难以澄清相关的脆弱性、影响、风险和责任。因此，这项拟议研究的目标是为多重不确定情况下的空气和废物管理开发一种基于优化的脆弱性和风险分析方法；这需要(A)分析空气和废物管理系统的复杂性，(B)在多种不确定情况下开发不精确的优化技术，(C)推进基于优化的脆弱性和风险分析方法，以及(D)将已开发的不精确的优化技术和脆弱性/风险分析方法纳入一般决策支持框架。将开发先进的不精确的优化方法，以解决空气和废物管理系统中存在的各种形式的复杂性。在优化分析的基础上，将进一步发展一套脆弱性/风险评估方法，以分析人类干预对受体系统脆弱性的综合影响以及多种环境问题造成的复合风险。然后，所开发的技术将应用于加拿大西部的空气和废物管理。拟议的研究将为应对与空气和废物管理有关的脆弱性/风险分析方面的挑战提供技术和方法支持。它将有助于全面审议与环境管理和风险分析决策有关的因素。将拟议的技术应用于加拿大案例将有助于行业和政府提高其管理环境问题的有效性。此外，一些研究生和本科生将通过参与拟议的研究进行培训。这些训练有素的学生将满足不同行业对环境管理专业人员的迫切需求。

Air and waste management systems are complicated with many uncertain parameters and their interrelations that present in terms of multiple uncertainties, while the related decision problems are of interactive, dynamic and multiobjective features. These lead to difficulties in clarifying the related vulnerabilities, impacts, risks and liabilities under a variety of system conditions and policy scenarios. Consequently, the objectives of this proposed research is to develop an optimization-based vulnerability and risk analysis approach for air and waste management under multiple uncertainties; this entails (a) analysis of complexities in air and waste management systems, (b) development of inexact optimization techniques under multiple uncertainties, (c) advancement of optimization-based vulnerability and risk analysis approaches, and (d) incorporation of the developed inexact optimization techniques and vulnerability/risk analysis approaches within a general decision-support framework. Advanced inexact optimization methodologies will be developed for addressing various forms of complexities that exist in air and waste management systems. Based on the optimization analysis, a set of vulnerability/risk assessment methods will be further developed for analyzing the comprehensive effects of human interventions on the vulnerability of receptor systems as well as the compound risks caused by multiple environmental concerns. The developed technologies will then be applied to air and waste management within a western Canada context. The proposed study will provide technical and methodological supports for tackling challenges of vulnerability/risk analysis in relation to air and waste management. It will facilitate comprehensive consideration of factors that are related to the decisions of environmental management and risk analysis. Applications of the proposed techniques to Canadian cases will help industries and governments to improve their effectiveness in managing environmental problems. Besides, a number of graduate and undergraduate students will be trained through participation in the proposed research. The trained students will fill a pressing need for environmental management professionals in various sectors.
