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

大气与废弃物管理系统是一个复杂的系统，存在许多不确定性参数及其相互关系，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。这导致难以澄清各种系统条件和政策设想下的相关脆弱性、影响、风险和责任。因此，这项拟议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，用于在多种不确定性下的空气和废物管理;这需要（a）分析空气和废物管理系统中的复杂性，（B）开发在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）在一般性决策支助框架内纳入已开发的不精确优化技术和脆弱性/风险分析办法。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，进一步发展了一套脆弱性/风险评估方法，用于分析人类干预对受体系统脆弱性的综合影响，以及多种环境问题引起的复合风险。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/风险分析挑战提供技术和方法支持。这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。将所提出的技术应用于加拿大的案例，将有助于工业界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进行培训。受训的学生将填补各部门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.
