Supporting software quality in an integrated safety-critical systems development environment

Research is described, aimed to support traceability in the design of software for safety-critical applications, through the provision of an on-line design journal enabling design decisions and actions to be traced and recorded. The design environment, within which various software design tools may be encapsulated, enables protocol between the user and the design tools to be trapped. This provides software engineering support at the conceptual design stage. An important aim of the research is to enable inferences to be made from the captured protocol, for which the application of artificial intelligence methods is being investigated.     

System dynamics in software project management: towards the development of a formal integrated framework

Successful software development is becoming increasingly important to many companies. However, most projects fail to meet their targets, highlighting the inadequacies of traditional project management techniques in this unique setting. Despite breakthroughs in software engineering, management methodologies have not improved, and the major opportunities for better results are now in this area. Poor strategic management and related human factors have been cited as a major cause for failures, which traditional techniques cannot incorporate explicitly. System dynamics (SD) aims to model the behaviour of complex socio-economic systems; there has been a number of applications to software project management. SD provides an alternative view in which the major project influences are considered and quantified explicitly. Grounded on a holistic perspective it avoids consideration of the detail required by traditional tools, looking at the key aspects of the general project behaviour. However, if SD is to play a key role in software project management it needs to be embedded within the traditional decision-making framework. The authors developed a conceptual integrated model, the SYDPIM, which has been tested and improved within a large on-going software project. Such a framework specifies the roles of SD models, how they are to be used within the traditional management process, how they exchange information with the traditional models, and a general method to support model development.

Experience report: evolution of a web‐integrated software development and verification environment

This paper summarizes our experiences over the last 4 years in creating a web‐integrated software development and verification environment. The environment has been used for both research experimentation and education. It has been used in undergraduate computer science courses to teach modular software development and analytical reasoning principles at multiple institutions. In the process, the environment has undergone many refinements to meet demands for improved functionality and to leverage rapidly changing underlying technology for the improvements. The environment is tailored to present formal specifications and alternative implementations of components, and enable correctness checking through a server‐side verifying compiler. This paper presents a detailed account of the development and evolution of the environment—its functionality, user interface, and underlying technology—that we hope will serve as a model for others, especially as the benefits of online learning systems are becoming increasingly obvious.

SUT-DAM: An integrated software environment for multi-disciplinary geotechnical engineering

As computer simulation increasingly supports engineering design, the requirement for a computer software environment providing an integration platform for computational engineering software increases. A key component of an integrated environment is the use of computational engineering to assist and support solutions for complex design. In the present paper, an integrated software environment is demonstrated for multi-disciplinary computational modeling of structural and geotechnical problems. The SUT-DAM is designed in both popularity and functionality with the development of user-friendly pre- and post-processing software. Pre-processing software is used to create the model, generate an appropriate finite element grid, apply the appropriate boundary conditions, and view the total model. Post-processing provides visualization of the computed results. In SUT-DAM, a numerical model is developed based on a Lagrangian finite element formulation for large deformation dynamic analysis of saturated and unsaturated soils. An adaptive FEM strategy is used into the large displacement finite element formulation by employing an error estimator, adaptive mesh refinement, and data transfer operator. This consists in defining new appropriate finite element mesh within the updated, deformed geometry and interpolating (mapping) the pertinent variables from one mesh to another in order to continue the analysis. The SUT-DAM supports different yield criteria, including classical and advanced constitutive models, such as the Pastor–Zienkiewicz and cap plasticity models. The paper presents details of the environment and includes several examples of the integration of application software.     

Flow: A software development environment using diagrams

The multiuser software development system FLOW uses a diagrammatic language, FLOW-DL, to represent the system under development. Once a module has been keyed in, one of three post-processors is called to generate source code in Pascal, Fortran, or Cobol. A fourth post-processor generates documentation. The system also includes a syntax-directed editor, as well as a software production data base which holds the FLOW-DL source code, interface data relating to the program modules, and control information pertaining to the state of the system under development. The package is portable; a graphics terminal is not required. Versions of the production system have been used for the past 4 years to develop a number of medium-sized software systems.     

Toward a new software development environment

The Lyee methodology allows the development of a software by simply defining its requirements. More precisely, a developer has only to provide words, calculation formulae, calculation conditions and layout of screens and printouts, and then leaves in the hands of the computer all subsequent troublesome programming process, i.e. control logic aspects. The formalization of Lyee methodology led to the definition of Lyee-Calculus, a formal process algebra, that easily and naturally supports the basic concepts of the Lyee methodology. Moreover, we provided an implementation of the constructs of the Lyee-Calculus in Java language in order to concretely show the efficiency of this calculus and its suitability for the Lyee methodology. In other words, this Java implementation of the Lyee-Calculus provides a means of bridging the gap between Lyee requirement specifications and their implementations.In this paper, we present a new software development environment, LyeeBuilder, that allows to automatically generate applications from specifications using a GUI interface. This software aims to give to programmers an environment that allows them to automatically generate applications from screens and word definitions.
