Enterprise Modeling Languages (EMLs) are generally perceived as conceptual modeling languages having a formal syntax and informal semantics. The non-formality of semantics is mainly caused by the materiality of the addressed domain (enterprises and its related aspects) and the resulting personal interpretation of syntactical constructs. However, EMLs may also explicitly define invariant interpretations...
This paper presents the fuzzy mathematical model of transfer criteria of distribution network to 20 kV voltage by analyzing the parameters of the distribution network. The model used for the rapid analysis of priority network licensees to determine the order of their funding. As the basis of the synthesized criteria model was accepted a linguistic definition of priority transfer distribution network...
Formalized definition of the concept of «model» is proposed, a brief analysis of the existing approaches in the classification of systems' models is represented, due to the concept of models' classification based on methods of modeling. Approaches and methods of modeling and the structure of proposed classification are described. Methods presented are divided in methods for formalization of presentation...
The main purpose of the research is development of methodology of a statistical investigation of effective management of Russian power engineering enterprises production assets which is realized on the basis of artificial intelligence methods to create information analysis systems of the analysis of technological risks of new generation. Mathematical modeling was the research method used in experimental...
In this paper, a novel intelligent modeling framework is introduced for modeling hybrid dynamical systems, which may contain both continuous-valued and discrete-valued dynamics and/or signals. The proposed modeling framework consists of a fuzzy relational hybrid model (FRHM) structure and an online identification algorithm. The FRHM structure has some useful properties, e.g., the ability of modeling...
Organizational performance is one of the most important aspects of today's project management research. Many factors can be indicators for organizational performance beyond the financial measures. Predicting the performance will allow the organization to identify the areas with the highest improvement potentials, thus leading to better performance and profit increasing. The fragmented and unique nature...
This study applied relationship life cycle concept and separated two stages including relationship development and relationship maintenance to derivate influence factors in each stage based on relative literature for relationship development. This study proposed a model which called “Relationship Hierarchy Structural Fuzzy ANP Model”, and apply this model to investigate and compare interaction, influence,...
This paper proposes two validation analyses, namely the risk attitudes and level of confidence for fuzzy multi-criteria decision-making model. Risk attitudes are employed to test the outcomes in dealing with the different decision maker's attitude towards risk and uncertainty. Conversely, confidence analysis are used to test how confidence (i.e., pessimistic, moderate, optimistic, etc.) decision makers...
Mobile learning, the learning method which learners can leverage mobile devices to learn everywhere, has become the one of the most potential learning approach as novel mobile devices emerges. However, how the novel mobile learning technology can be accepted by learners was seldom addressed. Meanwhile, due to the unavailability of large number (more than 100) experts for evaluating novel mobile learning...
The paper attempts to investigate the statistical structure of letters and of letter digrams with which the words begin and end, as well as of trigrams that link two successive words. The investigation is carried out on a printed Romanian literary corpus summing up about 12.5 million words. The impact of the orthography and punctuation marks in the language model assigned to the beginning and to the...
This study employs Regression analysis to establish the implicit importance of quality attributes and the overall satisfaction, and adopt the fuzzy DEMATEL, which consider the fuzziness of human thinking, to calculate the causal relationship and the influential degree among each quality attribute, and then proposes a new methodology of decision analysis, which modifies the traditional IPA model and...
Analysis of project risk, which depends on basic software risk level of projects with iterative lifecycle and software development project model are made by the authors. Fuzzy model for the project risk are proposed by the authors.
