9th IEEE/ACM International Workshop on modelling in software Engineering (MiSE)

作者： Chaudron, Michel R. V. Chalmers Gothenburg Univ Dept Comp Sci & Engn Gothenburg Sweden

ISBN: (纸本)9781538604267

A key open question in the area of software modeling is which costs and benefits it brings to software development and maintenance. For answering this question, better empirical studies into software modeling are needed. In this paper I focus on what I believe are the pitfalls in-and prospects for such types of studies. This paper is an abstract for an invited keynote at the modeling in software Engineering (MiSE) workshop at ICSE 2017.

Modern automotive control softwareconsist of a large number of reusable components, often responsible for safety critical functions. The quality and performance of these components is linked to temporal properties, which depend on the real-time behavior of interconnected processing units. Existing approaches consider requirements on temporal properties only in the context of central-architectural decision making based on observable events. This paper presents a novel more distributed approach to document such requirements that also includes abstract properties used in control engineering such as aliasing. We provide a framework in which requirements for these abstract properties are documented as part of the interface specifications based on a lightweight extension of event models. During integration, these requirements are tested with established analysis methods. We demonstrate the usability of our approach by analyzing an existing engine control software in regard to a property that could not be computed automatically before.

Recent studies show sixty percent of older adults access the internet at least once a week. However, poor website usability and design have been identified as two key factors which negatively impact internet usage among this demographic. Often the specific needs of this user group are not addressed properly by modern web application design, and this can hinder the usability and user experience of these applications and sites for older adults. To solve this issue, we have developed a universal design approach by introducing software-modeling constraints for the MVC design pattern to better address the needs of older adult users on the web.

The purpose of the Lunar Atmosphere Dust Environment Explorer (LADEE) mission was to measure the density, composition and time variability of the lunar dust environment. The ground-support and onboard flight software for the mission was developed using a "model-based software" methodology. In this technique, models of the spacecraft and flight software are developed in a graphical dynamics modeling package. Flight software requirements are prototyped and refined using the simulated models. After the model is shown to work as desired in this simulation framework, C-code software is automatically generated from the models. The auto-generated code is then integrated with the Core Flight Executive and Core Flight Services (cFE/cFS) packages, VxWorks and appropriate board support packages. The generated software is then tested in real time Processor-in-the-Loop and Hardware-in-the-Loop test beds. software cost estimation for the mission was performed 3 ways: 1) Extrapolated from development of a earth-based prototype hover-test vehicle, 2) Estimated through the Goddard Space Flight Center "mission design center" 3) Through the use of COCOMO based estimation spreadsheets. In this paper, we will discuss the characteristics of each of the cost estimation methods, and how they were tuned for a model-based development effort rather than a traditional effort. The estimates are also compared with actual costing and trend data for the LADEE Flight software effort.

Industrial manufacturing processes are complex processes, where transparency of every process step is necessary to achieve a high level of quality and efficiency. In order to achieve this transparency, manufacturing execution systems (MES) are used. However, as these systems are very expensive, mainly due to individual programming effort, MES usage is oftentimes limited to larger companies. To ultimately reduce implementation costs for MES, the current research project AutoMES proposes a standardized, model-based approach to facilitate automatic generation of MES functions. This paper presents requirements on a suitable modeling language, as well as how these requirements are fulfilled by the modeling language used in the AutoMES project. The modeling language is an extension of the MES modeling Language (MES-ML), a modeling language for the specification of MES. With the use of the extended MES-ML it is possible to generate a generic, machine-usable MES specification, suitable for code generation. To evaluate the proposed modeling language extensions, an industrial brewing process has been modeled and verified by MES engineers during the project AutoMES.

This paper presents an application of agile method on academic access and fraud control system. It describes the conceptualization, development, and testing process of a case study, using Problem based Learning (PBL) and some collaborative tools. It was developed, on the 1st semester of 2012, at the Brazilian Aeronautics Institute of Technology (Instituto Tecnologico de Aeronautica - ITA) by graduate students during three different multidisciplinary courses involving geographically distributed teams. Its main results are presented, discussed, and analyzed, providing an overview of a successful new academic application development.

Towards model-based Virtual Wet Lab Experiments 14

Towards Model-Based Virtual Wet Lab Experiments

Often virtual wet lab experiments are not exactly experimental. They simply require a series of mouse clicks to be performed in the exact order intended by the programmer. While this does not sound like fun for the students, too open activities are not helpful either. Instead students should be allowed to vary their learning path wherever possible, mimicking a 'real' experiment. This paper outlines a model-based approach which can provide this flexibility while reducing programming efforts for new virtual wet lab experiments. Lab equipment, chemicals, and lab activities are to be modeled beforehand in order to be made available in an 'experiment construction kit' for teachers and students.

software systems start small and grow in complexity and size. The larger a software system is, the more it is distributed over organizational and geographical confines. Thus, the modeling of software systems is necessary at a certain level of complexity because it can be used for communication, documentation, configuration and certification purposes. We came to the conclusion that several patterns of software modeling exist. The existence of such patterns is dependent on the history and the evolution of the system under consideration. We will show that a software system in its lifecycle has to face several crises. Such a crisis is a watershed in the application of new patterns. We provide an evolutionary view of software systems and models which helps understanding of current problems and prospective solutions.

PERSIST—A Flexible and Automatically Verifiable software Architecture for the Automotive Powertrain

Abstract： In the light of an increasing software complexity, many product variants and challenging market conditions, the automotive industry focuses two mitigation approaches： development processes and SW （software） architecture are standardized while model-driven software development technologies are progressively applied for series development. However, software architecture is subject to a continuous shift of requirements and boundary conditions. At the same time, process standards ensure necessary quality but also cause a dramatic increase of the SW development effort. There exists a methodical gap between process and market requirements on one hand and reusable standardized software functions with a high quality on the other. In this paper, an approach is presented that aims for the continuous extension of powertrain control software with increasing quality based on existing boundary conditions and a consequent methodical extension of existing technical concepts. We address this by the development of a sustainable software architecture which enables the safeguarding of consistent design principles and thus higher development efficiency. Moreover, it opens the door to a comprehensive quality assurance concept based on the agile software development principle Continuous Integration. Finally, the feasibility of this approach and software quality assessment results are shown by the application for a gasoline engine in the vehicle.
