GOMES, Luiz Flávio Autran Monteiro; RANGEL, Luis Alberto Duncan and LEAL JUNIOR, Miguel da Rocha. Treatment of uncertainty through the interval smart/swing weighting method: a case study. Pesqui. Oper. [online]. 2011, vol.31, n.3, pp.467-485. ISSN 0101-7438. http://dx.doi.org/10.1590/S0101-74382011000300004.
An increasingly competitive market means that many decisions must be taken, quickly and with precision, in complex, high risk scenarios. This combination of factors makes it necessary to use decision aiding methods which provide a means of dealing with uncertainty in the judgement of the alternatives. This work presents the use of the MAUT method, combined with the INTERVAL SMART/SWING WEIGHTING method. Although multicriteria decision aiding was not conceived specifically for tackling uncertainty, the combined use of MAUT and the INTERVAL SMART/SWING WEIGHTING method allows approaching decision problems under uncertainty. The main concepts which are involved in these two methods are described and their joint application to the case study concerning the selection of a printing service supplier is presented. The case study makes use of the WINPRE software as a support tool for the calculation of dominance. It is then concluded that the proposed approach can be applied to decision making problems under uncertainty.
