Use case modeling, including use case diagrams and use case specifications (UCSs), is commonly applied to structure and document requirements. UCSs are usually structured but unrestricted textual documents complying with a certain use case template. However, because Use Case Models (UCMods) remain essentially textual, ambiguity is inevitably introduced. In(More)
Use cases are commonly used to structure and document requirements while UML activity diagrams are often used to visualize and formalize use cases, for example to support automated test case generation. Therefore the automated support for the transition from use cases to activity diagrams would provide significant, practical help. Additionally, traceability(More)
During iterative, UML-based software development, various UML diagrams, modeling the same system at different levels of abstraction are developed. These models must remain consistent when changes are performed. In this context, we refine the notion of impact analysis and distinguish horizontal impact analysis–that focuses on changes and impacts at one level(More)

Model transformation is one of the basic principles of Model Driven Architecture. To build a software system, a sequence of transformations is performed, starting from requirements and ending with implementation. However, requirements are mostly in the form of text, but not a model that can be easily understood by computers; therefore, automated(More)
Context. Integrated control systems (ICSs) are heterogeneous systems where software and hardware components are integrated to control and monitor physical devices and processes. A family of ICSs share the same software code base, which is configured differently for each product to form a unique installation. Due to the complexity of ICSs and inadequate(More)
The transition from an informal requirements specification in natural language to a structured, precise specification is an important challenge in practice. It is particularly so for object-oriented methods, defined in the context of the OMG's Model Driven Architecture (MDA), where a key step is to transition from a use case model to an analysis model.(More)
BACKGROUND The axillary reverse mapping (ARM) procedure can distinguish lymphatics draining the arm from those draining the breast. It has been proposed to preserve lymphatic drainage of the upper limbs and reduce the incidence of upper limb lymphedema during breast cancer surgery. The aim of our study was to assess the feasibility of ARM in modified(More)
MARTE (Modeling and Analysis of Real-Time and Embedded Systems) is a UML profile, which has been developed to model concepts specific to Real-Time and Embedded Systems (RTES). In previous years, we have applied UML/MARTE to three distinct industrial problems in various industry sectors: architecture modeling and configuration of large-scale and highly(More)
