N. SMITH The University of Queensland, Australia This article outlines some aspects of ordered weighted averaging (OWA) operators as a framework in the evaluation of alternative environmental projects. OWA operators are considered in the context of the linguistic or non-numeric aggregation of factors and the importance weight of those factors. A simple example drawn from Horsak and Damico [1] is given which involves the location of a hazardous waste disposal facility at one of three sites based on ten factors. OWA aggregation operators are considered in the context of the above illustrative example. It is concluded that non-numeric OWA operators have considerable potential in providing a framework for the aggregation of linguistic labels in the evaluation of projects with environmental consequences.
