摘要:This paper presents a framework for estimating the robustness of appraisal of transport projects using a composite appraisal methodology which makes use of both cost-benefit analysis (CBA) and multi-criteria analysis (MCA). The setting of criteria weights in MCA is often seen as the most subjective part of the analysis and is frequently a subject for discussion. The methodology examined here makes use of importance order for setting the criteria weights. This means that all the decision makers or stakeholders involved have to do is rank the criteria by their importance. The setting of criteria weights can make a big difference in the resulting assessment of alternatives. This paper presents a methodology for testing the robustness of the assigned weights to the analysis and thereby gives information about how different preferences about the importance of the criteria may result in a different outcome of the appraisal. The work on the two case studies presented in this paper illustrates that the methodology is particularly useful where groups make decisions, when it is often hard to get agreement about the setting of the weights. The analysis can defuse a potentially lengthy debate about the weights and thereby leave more time for discussing other parts of the analysis among the decision makers. The methodology may be useful in a wide variety of contexts outside the field of transport projects.
