Full-text available
Nowadays, there is a great interest in expressing uncertain concepts by means of fuzzy set theory proposed by L.A. Zadeh. The application of the fuzzy sets theory includes a fuzzification process that expresses an uncertain concept by a membership function (MF). However, due to a lack of a general systematic approach for the fuzzification process,...

The ontology-based information systems (IS) development is beneficial for analyzing, conceptual modeling, designing, and re-engineering complex IS to be semantically enriched and suitable for sophisticated reasoning on the IS content. On the other hand, fuzzy theory employment to handle uncertainty and fuzziness in IS becomes a hot topic in differe...
Article
The data-driven approach is popular to automate learning of fuzzy rules and tuning membership function parameters in fuzzy inference systems (FIS) development. However, researchers highlight different challenges and issues of this FIS development because of its complexity. This paper evaluates the current state of the art of FIS development complex...
Article
Nowadays, there is a lack of smart marine monitoring systems, which have possibilities to integrate multi-dimensional components for monitoring and predicting marine water quality and making decisions for their optimal operations with minimal human intervention. This research aims to extend the smart coastal marine monitoring by proposing a solar e...
Chapter
The development of a data-driven fuzzy inference system (FIS) involves the automatic generation of membership functions and fuzzy if-then rules and choosing a particular defuzzification approach. The literature presents different techniques for automatic FIS development and highlights different challenges and issues of its automatic development bec...
Article
Nowadays, data-driven fuzzy inference systems (FIS) have become popular to solve different vague, imprecise, and uncertain problems in various application domains. However, plenty of authors have identified different challenges and issues of FIS development because of its complexity that also influences FIS quality attributes. Still, there is no co...
Article
Fuzzy approaches that are proposed to describe uncertain, impressive or vague concepts, are based on the construction of membership function (MF), which reflects what is known about the linguistic variables in the application domain. However, a non-trivial problem exists in how to construct the most appropriate MF that has the best-fit representati...

The aim of the paper is twofold. On the one hand, it reflects the experience gained supervising master and doctoral theses/dissertations in various Lithuania universities and highlights some common challenges and concerns. On the other hand, it acknowledges with some advanced library research methods and that facilitate writing of postgraduate lite...
Article

The symbiosis between an enterprise architecture and service-oriented architecture results in so-called service-oriented enterprise architecture and brings up new problems for service-oriented enterprise systems engineering. One of the most important is a business service quality definition, specification and evaluation. The paper proposes a formal...
Article
Service-oriented enterprise architecture and emerging advanced technologies bring up new problems for enterprise systems engineering or, more exactly, for service-oriented enterprise systems (SoESs) engineering. One of the most important issues is the modelling of quality of services (QoS). The QoS is a complex and multi-sided concept. In various c...

Straipsnyje aptariami, analizuojami ir vertinami svarbiausi pasiūlymai, kaip spręsti pasaulinio saityno paslaugų kompozicijų skaidymo į modulius uždavinį. Tai yra vienas iš aktualiausių e. verslo sistemų kūrimo uždavinių, kurio neišsprendus neįmanoma adekvačiai apdoroti vykdymo meto įvykių, dinamiškai perplanuoti verslo procesų, atsižvelgti į pasla...

Straipsnyje analizuojami ir lyginami trijų studentų apklausų rezultatai. Visose apklausose naudotas tas pats klausimynas. Pirmosios dvi apklausos vyko Vilniaus verslo kolegijoje 2007–2008 metais. Pirma iš jų tikrino tik įstojusių studentų informacinių technologijų žinias. Antra apklausa vyko pavasario semestro pabaigoje, baigiant informacinių techn...
