Title: Systematic comparative and sensitivity analyses of additive and outranking techniques for supporting impact significance assessments

Abstract

Assessing the significance of environmental impacts is one of the most important and all together difficult processes of Environmental Impact Assessment. This is largely due to the multicriteria nature of the problem. To date, decision techniques used in the process suffer from two drawbacks, namely the problem of compensation and the problem of identification of the 'exact boundary' between sub-ranges. This article discusses these issues and proposes a methodology for determining the significance of environmental impacts based on comparative and sensitivity analyses using the Electre TRI technique. An application of the methodology for the environmental assessment of a Power Plant project within the Valencian Region (Spain) is presented, and its performance evaluated. It is concluded that contrary to other techniques, Electre TRI automatically identifies those cases where allocation of significance categories is most difficult and, when combined with sensitivity analysis, offers greatest robustness in the face of variation in weights of the significance attributes. Likewise, this research demonstrates the efficacy of systematic comparison between Electre TRI and sum-based techniques, in the solution of assignment problems. The proposed methodology can therefore be regarded as a successful aid to the decision-maker, who will ultimately take the final decision.

  • The first-order functional sensitivity densities [delta] ln[sigma][sub 1/2[r arrow]3/2]([ital E])/[delta] ln[ital W][sub [vert bar][Lambda][vert bar]]([ital R]) are employed to assess the role of structure in the potential-energy curves [ital W][sub 0]([sup 2][Sigma]) and [ital W][sub 1]([sup 2][Pi]) mediating the fine-structure transition Na([sup 2][ital P][sub 1/2])+He[r arrow]Na([sup 2][ital P][sub 3/2])+He and Na([sup 2][ital P][sub 1/2])+Ar[r arrow]Na([sup 2][ital P][sub 3/2])+Ar. The sensitivity density profiles [delta] ln[sigma][sub 1/2[r arrow]3/2]([ital E])/[delta] ln[ital W][sub [vert bar][Lambda][vert bar]]([ital R]) for the two systems reveal that regions of significance differ widely for the [sup 2][Sigma] and [sup 2][Pi] curves. The results suggest that prevalent mechanistic explanations frommore » adiabatic analyses have limitations in terms of the ultimate significance of the identified kinematic coupling over well demarcated radial and angular coupling regions. The functional sensitivity analysis is shown to permit a full deconvolution of the collision cross section's dependence on the features in the individual [sup 2][Sigma] and [sup 2][Pi] curves as opposed to the adiabatic analysis where only the features in [[ital W][sub 0]([ital R])-[ital W][sub 1]([ital R])] are deemed critical to the collisional outcome.« less
  • A review of adsorption chromatography in coal liquids analyses reveals a multitude of closely related methods. This paper makes use of the distribution coefficient measurement (K /SUB D/ ) as a tool for systematically evaluating chromatographic separations. The K /SUB D/ for model compounds can be used to select adsorbents, optimize elution solvents, and standardize activity. Such K /SUB D/ measurements have been used to design a scheme for separating coal liquids into five well defined fractions.
  • Uncertainty is virtually unavoidable in environmental impact assessments (EIAs). From the literature related to treating and managing uncertainty, we have identified specific techniques for coping with uncertainty in EIAs. Here, we have focused on basic steps in the decision-making process that take place within an EIA setting. More specifically, we have identified uncertainties involved in each decision-making step and discussed the extent to which these can be treated and managed in the context of an activity or project that may have environmental impacts. To further demonstrate the relevance of the techniques identified, we have examined the extent to which themore » EIA guidelines currently used in Colombia consider and provide guidance on managing the uncertainty involved in these assessments. Some points that should be considered in order to provide greater robustness in impact assessments in Colombia have been identified. These include the management of stakeholder values, the systematic generation of project options, and their associated impacts as well as the associated management actions, and the evaluation of uncertainties and assumptions. We believe that the relevant and specific techniques reported here can be a reference for future evaluations of other EIA guidelines in different countries. - Highlights: • uncertainty is unavoidable in environmental impact assessments, EIAs; • we have identified some open techniques to EIAs for treating and managing uncertainty in these assessments; • points for improvement that should be considered in order to provide greater robustness in EIAs in Colombia have been identified; • the paper provides substantiated a reference for possible examinations of EIAs guidelines in other countries.« less
  • The subject of this paper is a comparative analysis of the plasma parameters inferred from the classical Langmuir probe procedure, from different theories of the ion current to the probe, and from measured electron energy distribution function (EEDF) obtained by double differentiation of the probe characteristic. We concluded that the plasma parameters inferred from the classical Langmuir procedure can be subjected to significant inaccuracy due to the non-Maxwellian EEDF, uncertainty of locating the plasma potential, and the arbitrariness of the ion current approximation. The plasma densities derived from the ion part of the probe characteristics diverge by as much asmore » an order of magnitude from the density calculated according to Langmuir procedure or calculated as corresponding integral of the measured EEDF. The electron temperature extracted from the ion part is always subjected to uncertainty. Such inaccuracy is attributed to modification of the EEDF for fast electrons due to inelastic electron collisions, and to deficiencies in the existing ion current theories; i.e., unrealistic assumptions about Maxwellian EEDFs, underestimation of the ion collisions and the ion ambipolar drift, and discounting deformation of the one-dimensional structure of the region perturbed by the probe. We concluded that EEDF measurement is the single reliable probe diagnostics for the basic research and industrial applications of highly non-equilibrium gas discharge plasmas. Examples of EEDF measurements point up importance of examining the probe current derivatives in real time and reiterate significance of the equipment technical characteristics, such as high energy resolution and wide dynamic range.« less
