Abstract:

The literature on transportation level-of-service (LOS) evaluation indicates a strong impetus to move away from a strictly capacity/volume- or time/space-based measure to one that directly incorporates the perception of passengers. The difficulty has been that whereas such quantitative measures are reasonably simple to measure, other LOS attributes related to convenience and comfort are qualitative in nature. Such attributes obviously are better expressed in qualitative terms. A review of the literature indicates that suggested methodologies fail to incorporate directly passengers' service perceptions, as expressed in natural language. The use of fuzzy set theory, particularly linguistic fuzzy set models, as a technique for evaluating transportation LOSs is explored. An approach for evaluating airport passenger services using linguistic variables and fuzzy sets is presented. LOS is conceptualized as a hierarchical service system with subcomponents. An example of the model applied to an evaluation of airport terminal services is presented.
