Roy's criterion determined by oriented fuzzy discount factor

Anna Łyczkowska-Hanćkowiak , Krzysztof Piasecki


The subject of the analysis will be security with present value evaluated by ordered fuzzy number. This means that present value was estimated in an imprecise manner and supplemented by the forecast of its future changes. This present value is called oriented fuzzy present value. The discount factor of such security is ordered fuzzy number. All classic portfolio analysis methods are based on the concept of a return rate. On the other hand, the literature showed that in the case of securities with fuzzy present value, the discount factor is a better tool for portfolio analysis than the return rate. This raises the postulate of re-writing selected security management methods to equivalent methods based on discount factor. This will allow the application of these methods to the case of a security with present value evaluated by ordered fuzzy number. In this work an exemplary result of the implementation of the above postulate is presented. The main purpose of the presented article is to generalize the Roy’s criterion to the case of management of investment recommendations formulated towards security characterized by the oriented discount factor.
