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

空气和废物管理系统具有许多不确定参数及其相互关系的复杂性，这些参数及其相互关系表现为多重不确定性，而相关决策问题具有交互性、动态性和多目标性。这导致在各种制度条件和政策情景下难以明确相关的脆弱性、影响、风险和责任。因此，本研究的目标是开发一种基于优化的脆弱性和风险分析方法，用于多种不确定因素下的空气和废物管理；这需要(a)分析空气和废物管理系统的复杂性，(b)开发多种不确定性下的不精确优化技术，(c)推进基于优化的脆弱性和风险分析方法，以及(d)将开发的不精确优化技术和脆弱性/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，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因素引起的复合风险。开发的技术随后将应用于加拿大西部地区的空气和废物管理。拟议的研究将为应对与空气和废物管理有关的脆弱性/风险分析的挑战提供技术和方法上的支持。它将有助于全面考虑与环境管理和风险分析决策有关的因素。将建议的技术应用于加拿大的案例将有助于工业和政府提高管理环境问题的效率。此外，一些研究生和本科生将通过参与拟议的研究而得到培训。训练有素的学生将填补各行各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.
