Airline Loyalty Determinants among Business Travelers: Empirical Evidence from Croatia
2017
AbstractAirline passenger loyalty has been the subject of several studies set within a general travel context. These studies have helped understanding the influence of variables like brand equity, airline service levels, customer commitment, but also price in tying a passenger to a particular airline. Despite the great economic importance of the business traveler market, no study has, however, so far, exclusively focused on this traveler segment and tried to investigate drivers of repurchase intentions and loyalty of this specific traveler type. This study aims to address this research gap. The findings reveal that business passenger loyalty is far stronger driven by emotional than rational…

In a context of strong increase of fuelwood demand in the collective sector, the supply issue becomes central to all stakeholders, raising many issues relating to land and forestry planning, local development, environment ... Meanwhile, questions emerge: how much energy can be mobilized sustainably? Does the spatial and structural configuration of forests influence the supply process? Do we seek to minimize transport distances? Can we observe spatial competition between the boilers ? To understand the current organization of supplies, we analyzed two sets of data traceability of wood chips. Then, we have developed a model of local supply basins, considering constraints of renewability of th…
Framework for Evaluating the Version Management Capabilities of a Class of UML Modeling Tools from the Viewpoint of Multi-site, Multi-partner Product…
2009
UML models are widely used in software product line engineering for activities such as modeling the software product line reference architecture, detailed design, and automation of software code generation and testing. But in high-tech companies, modeling activities are typically distributed across multiple sites and involve multiple partners in different countries, thus complicating model management. Today’s UML modeling tools support sophisticated version management for managing parallel and distributed modeling. However, the literature does not provide a comprehensive set of industrial-level criteria to evaluate the version management capabilities of UML tools. This article’s contributio…

Modeling and Query Language for Hospitals
2013
So far the traditional process modeling languages have found a limited use in the hospital settings. One of the reasons behind this delay has been the lack of clear definition of the sequence of activities that are carried out in the hospital. We propose a new modeling language (as a profile of UML Class diagrams) that captures all the useful features from various UML diagrams and can be used in modeling of the hospitals. Based on the modeling language, we have developed an easy-to-perceive graphical query language, which allows the physicians to retrieve directly from the various hospital databases information they need to better understand the flow of clinical processes.
From UML Specification into FPGA Implementation
2014
In the paper a method of using the Unified Modeling Language for specification of digital systems, especially logic controllers, is presented. The proposed method is based mainly on the UML state machine di- agrams and uses Hierarchical Concurrent Finite State Machines (HCFSMs) as a temporary model. The paper shows a way to transform the UML diagrams, expressed in XML language, to the form that is acceptable by reconfigurable FPGAs (Field Programmable Gate Ar- rays). The UML specification is used to generate an eective program in Hardware Description Languages (HDLs), especially Verilog.

A Notation for Modeling Jason-Like BDI Agents
2012
The design and development of a large Multi Agent System (MAS) is a complex and difficult activity where a proper modeling notation may offer a significant contribution to the formulation of the best solution. The support provided by a specific CASE tool can significantly contribute to make the chosen approach technically valid and it is also a fundamental element of a feasible development strategy. The present work reports a UML profile and the related graphical notation for describing a MAS based on the Jason meta model. Moreover a specific CASE tool has been developed for supporting MASs design and automatic code generation. The proposed notation is shown in details using a classical exa…
Transformations Between UML Diagrams
2003
The Unified Modeling Language (UML) provides various diagram types for describing a system from different perspectives or abstraction levels. Hence, UML diagrams describing the same system are dependent and strongly overlapping. In this paper we study how this can be exploited for specifying transformation operations between different diagram types. We discuss various general approaches and viewpoints of model transformations in UML. The source and target diagram types for useful transformations are analyzed and given categories. The potentially most interesting transformation operations are discussed in detail. It is concluded that the transformation operations can automate a substantial p…
Reduction of UML Class Diagrams
2002
One and the same “real world” can be modeled by different UML class diagrams, which in such a case can be considered “intuitively equivalent”. A formalization of this “intuitive equivalence” of class diagrams is proposed. An algorithm is constructed that for two class diagrams determines if they model the same “real world”. This algorithm can be used in CASE tools to compare alternative models of a system, and for diagram “compression” to facilitate understanding of large diagrams.
