AbstractThe development of engineered systems is a complex process, involving many activities and development artifacts. The challenges introduced by this complexity calls for a model-based design environment. The PROVE methodology is an artifact-centric, model-based development process design methodology. In this paper, we present the first, fully model-based design environment of the PROVE. Furthermore, our environment incorporates additional process design perspectives that are applied in real-time and in a completely consistent manner, based on a formally defined information model. We discuss the details of our environment's design as well as highlight its potential benefits.

The planning of system development efforts is crucial to the successful realization of projects. However, development planning typically lacks systematic, engineering discipline, and consequently risks project and business success. Model-based process design is a potential information systems approach to addressing the increasing complexity of such planning. We characterize the ontology of development process design, based on real-life observations and scientific publications. We then synthesize the required ontology with the desirable characteristics of models, and derive key requirements for model-based development process design. Next, these requirements are used to evaluate the adequacy of three prominent, standardized model-based process design approaches—BPMN, OPM and SPEM. The findings reveal that the surveyed models are a partial fit, and do not promote sound process design. Finally, by generalizing the categorical evaluation results, possible root causes for the identified inadequacies are proposed. A new model design, which should rely on the formulated requirements set, is called for, in pursuit of a wider adoption of model-based design paradigms and better information systems realization to support the development of complex systems.

Purpose As the global paradigm in economics shifts, Islamic economics is attracting more attention as an alternative sector. The most common and most active institutional structure of Islamic economics is in the form of Islamic finance and banking. Islamic finance and banking have been the centre of innovation in many economies in recent years. In this regard, product development is a vital element in driving the success of Islamic financial institutions (IFIs). The product development of IFIs is one of the key elements of their overall economic performance. This study aims to fill the gap in the literature concerning the product development process of IFIs in secular economies. Design/methodology/approach Verily, product development is a complex process; it is likely that introducing specific models will be useful for expanding the activities of IFIs. In this study, contemporary source materials are used to develop this conceptual research. Findings It suggests two separate methodologies for the product development process of IFIs in secular economies to overhaul two criticised product-based problems. To the best of the author’s knowledge, it is the first attempt to model the product development process for IFIs in a secular economic setup. Originality/value Recently, this study is the first attempt for modelling product development in IFIs under secular economies. Advances in the field of Shari’ah-compliant product development is important for researchers and professional.

AbstractModel-Based Systems Engineering (MBSE) is an efficient approach to support product development in order to meet today's challenges. The MBSE approach includes methods and, above all, modelling approaches of the technical system with the aim of continuous use in development. The objective of this paper is to use the potential of the MBSE models and to show the added value of such models on the system level when used as a single source. With this objective, this paper presents a three-step approach to systematically identify and apply meaningful modelling approaches within MBSE, based on the needs during the development process. Furthermore, an FMEA example is included in this paper to elaborate the use of MBSE in the system failure analysis.

Die Automobilindustrie ist momentan im Begriff, einen neuen Ansatz für die Entwicklung eingebetteter Systeme zu übernehmen. Dieser Ansatz basiert auf neuen Modellierungs- und Simulationswerkzeugen, die einen nahtlosen Prozess von der ersten Idee bis zur Serie durch schrittweise Verfeinerung eines Modells und Implementierung mittels automatischer Codegenerierung versprechen. Jedoch müssen einige Details dieses Prozesses erst noch definiert werden. Dabei sollten Erfahrungen und erprobte Techniken aus traditionellen Softwareentwicklungsprozessen berücksichtigt werden. Zum Beispiel kann durch Zusicherungen das Modell abgesichert und seine Tiefe und Qualität verbessert werden. Solche Prüfungen können sowohl in der Simulation als auch zur Codegenerierung für die Zielumgebung verwendet werden. Dies führt zu einer erhöhten Zuverlässigkeit des Endprodukts und stellt au3erdem eine Grobverifikation des verwendeten Codegenerators dar. Der vorliegende Artikel beschreibt Konzept und Anforderungen für solche modellbasierten Prüfungen und ihren praktischen Einsatz mit SIMULINK-Modellen.

Purpose This paper aims to present a novel stageless evaluation scheme for a vector Preisach model that exploits rotational operators for the description of vector hysteresis. It is meant to resolve the discretizational errors that arise during the application of the standard matrix-based implementation of Preisach-based models. Design/methodology/approach The newly developed evaluation uses a nested-list data structure. Together with an adapted form of the Everett function, it allows to represent both the additional rotational operator and the switching operator of the standard scalar Preisach model in a stageless fashion, i.e. without introducing discretization errors. Additionally, presented updating and simplification rules ensure the computational efficiency of the scheme. Findings A comparison between the stageless evaluation scheme and the commonly used matrix approach reveals not only an improvement in accuracy up to machine precision but, furthermore, a reduction of computational resources. Research limitations/implications The presented evaluation scheme is especially designed for a vector Preisach model, which is based on an additional rotational operator. A direct application to other vector Preisach models that do not rely on rotational operators is not intended. Nevertheless, the presented methodology allows an easy adaption to similar vector Preisach schemes that use modified setting rules for the rotational operator and/or the switching operator. Originality/value Prior to this contribution, the vector Preisach model based on rotational operators could only be evaluated using a matrix-based approach that works with discretized forms of rotational and switching operator. The presented evaluation scheme offers reduced computational cost at much higher accuracy. Therefore, it is of great interest for all users of the mentioned or similar vector Preisach models.

Purpose This paper aims to outline the prosocial leadership development process for guiding pedagogical and social justice course goals as a means to foster prosocial leadership values within the millennial generation. Design/methodology/approach The paper is guided by a social justice framework and proven classroom pedagogies as a means to align millennial characteristics within the four stages of the prosocial leadership development process. Findings An educational rubric is provided as a means to guide classroom pedagogies, course goals and millennial characteristics through a prosocial leadership development process. Research limitations/implications The paper is conceptual in nature, and therefore, theoretical correspondence remains speculative. Practical implications The research in this paper provided guidelines for educators to use pedagogical practices as a means to develop prosocial values as a basis for organizational leadership behaviors. Social implications This leadership development process when facilitated through proven pedagogical techniques (guided by established social justice curriculum goals) and is within the context of millennial characteristics (those born between the years 1982 and 2005) becomes catalytic in empowering leaders to be a remedy for the world’s environmental and social challenges. Originality/value This paper connects characteristics of millennials to a prosocial leadership development model.
