Abstract Sustainable development necessitates the implementation of appropriate policies that integrate multiple competing objectives on economic, environmental, energy, and social criteria. Multi-criteria decision analysis with goal programming is a popular widely used technique for studying problems objectives. Real-world situations frequently involve imprecise incomplete information, making ...

We consider the asymmetric A-distance though it is not a metric due to the asymmetry in a rigorous sense. However, it reflects on an actual situation of urban areas that time from the demand point to the facility depends on the passing direction and in some places slopes and so it is asymmetric. Further, most residents in urban areas hope that even the city office should not be so near and so f...

The remarks made by Pauí Egré show the necessity of emphasizing the distinction between concepts and features as well as the difference of treatment this distinction leads to. Features, as such, borrow their sense from the context they are used in: it is only in the shadow of this context that their meaning can be grasped. When a feature is considered relatively to a given concept, like 'to hav...

In this paper we investigate multi-attribute decision making problem with single-valued neutrosophic attribute values. Crisp values are inadequate to model real life situation due to imprecise information frequently used in decision making process. Neutrosophic set is one such tool that can handle these situations. The rating of all alternatives is expressed with single-valued neutrosophic set ...

Conceptual vagueness reflect the fact that, apart from quantitative concept like to-be-young, to-be-tall, or even to-be-red, which can be qualified as fuzzy, there exist concepts for which membership is not an all-or-nothing matter. For these concepts, as observed by E. Rosch, the notion of membership degree must be substituted to that of the classical IS-A model. However, recent work on compos...

Plaque morphology in a diseased coronary artery plays a significant role in the modification of the fluid flow characteristics. The plaque morphology of forty-two patients who underwent IVUS (intravascular ultrasound) procedure was quantified by degree of membership in four fuzzy logic sets, which we refer as type I: protruding, type II: ascending, type III: descending, and type IV: diffuse. Of...

We study the uniform membership problem for hyperedgereplacement grammars that generate directed acyclic graphs. The study of this type of language is motivated by applications in natural language processing. Our major result is a low-degree polynomial-time algorithm that solves the uniform membership problem for a restricted type of such grammars. We motivate the necessity of the restrictions ...

In this work we study overlap degrees expressed in terms of overlap functions. We present the basic properties that from our point of view must satisfy these overlap functions. We study a construction method, we analyze which t-norms are also overlap functions and we prove that if we apply particular aggregations to such functions we recover the overlap index between fuzzy sets as defined by Du...
