Over the past several years, the Air Force Institute of Technology (AFIT) has been developing a formal-based software synthesis system, the AFIT Wide Spectrum Object Modeling Environment (AWSOME), along with a speci cation language AWL (AFIT Wide-spectrum Language). Several tools have been developed, including a parser for the AWL syntax, an interactive object editor, a Java code generator, and...

This paper discusses a method for generating test sequences from state-based specifications. We show how a model checker can be used to automatically generate complete test sequences that will provide arbitrary structural coverage of requirements specified in a high-level language like SCR or RSML−e. We have defined a language independent formal foundation for test sequence generation using mod...

Formal methods that are easy to use but with limited flexibility are sometimes criticized as inefficient and ineffective. This report took a detailed look at UPPAAL1 [1], a toolbox for modeling, simulating and verifying real-time systems, that is jointly developed by Uppsala University and Aalborg University. Specifically, components of the UPPAAL toolbox, the modeling language and the verifica...

The purpose of this paper is to advocate and encourage the application of fuzzy-neuro algorithms in the risk assessment of Distributed Real-Time (DRT) systems, where object-oriented and formal techniques by means of UML-SDL models are used as knowledge (data) providers to the fuzzy-neuro analyser. The paper includes an introductory description of DRT systems and the presentation of the UML and ...

This document is an addendum to Deliverable D1.3, focusing on a deeper analysis of UML and IDEF0 process modelling languages. In this new study we highlight the differences between the languages, and give a better support for preferring IDEF0 over UML as language to model the guideline development process. Moreover, we have reviewed and updated part of the data related to the selection of the p...

Alvis is a new modeling language for developing concurrent (embedded) systems. The language is being developed within the confines of the Alvis project at AGH University of Science and Technology, Department of Automatics. The Alvis language combines hierarchical graphical modelling with a high level programming language. Moreover, a formal verification of a model, based on an LTS graph (Labell...

Modeling languages are used by software engineers to design and document the structure and behavior of a system. Although many modeling languages have been proposed, Domain-Specific Modeling Languages (DSMLs) have emerged recently due to their simplicity and expressiveness for a particular domain. However, it is not easy for end-users to design and implement DSMLs because DSML development requi...

The use of strong typing, exemplified in the Ascend modeling language, is a recent phenomenon in executable modeling languages for mathematical modeling. It is also one that has significant potential for improving the functionality of computer-based modeling environments. Besides being a strongly typed language, Ascend is unique in providing operators that allow dynamic type inference, a featur...

Conceptual Modeling is a discipline of great relevance to several areas in Computer Science. In a series of papers [1,2,3] we have been using the General Ontological Language (GOL) and its underlying upper level ontology, proposed in [4,5], to evaluate the ontological correctness of conceptual models and to develop guidelines for how the constructs of a modeling language (UML) should be used in...

Natural language requirements specifications for complex application systems are difficult to analyze and to validate. Consequently, a more formal language for requirements representation is needed that is, for the purpose of validation, understood by endusers (i.e. the requirements owners), as well as by system analysts and developers. Often, the Unified Modeling Language UML is proposed for t...
