“…Here the first model does not specifically support the reuse of old, analogous models and there are also no common patterns being created from repeating abstractions. Again, the second model supports at least the reuse of previous models through the defined interfaces of functions, the flows, and there are already different patterns existing that have been learned from similar models created using analogous approaches [22][23][24].…”

“…Further, the library enables computational support as for instance through (semi-) automated decompositions [22] or by allocating to system elements [6]. This modeling support goes together with multiple common design approaches, such as the use of design patterns [23,24], recommendations for using SysML activity diagrams [18] or also approaches like forward chaining, backward chaining or other more general recommendations on how to create functional models [8,10]. Such design approaches do not exist to this extent for the first model without library and flow-based representation.…”

Systematic Comparison of Functional Models in SysML for Design Library Evaluation

The development of increasingly complex mechatronic, or more generally multi-disciplinary systems, is a challenge. It requires, among other things, efficient and computationally supported model-based conceptual design tools. One solution-and domain-independent approach developed to support this is a formal, functional modeling library in SysML, derived from the functional basis, that provides defined syntax and semantics. This paper presents a comparison of this approach with a more conventional SysML modeling approach to both evaluate the function model library and determine whether the two approaches should be integrated. In this comparison, current functional model benchmarks for representations and models are used to compare the approaches using a model of a hydrokeratome, which is a system to perform refractive eye surgery using a water jet. In general, the comparison shows that each approach has its strengths and weaknesses with respect to representation capabilities for particular applications, which leads to the conclusion that in the future the two approaches may complement one another well. Identified advantages of the function model library are that it is straight forward to use, generally applicably, as shown through the new application presented here, and enables potential for additional computer-based support, e.g. through semi-automated synthesis and model consistency checking.

“…Modelling framework is defined as a logical structure that can be applied in design practices to classify the design knowledge or to provide mechanisms for analyzing the information (R. J. Cloutier & Verma, 2007). Modelling frameworks can support the design process in two ways; first, defining what the structure of the design is in terms of required tasks and their sequence, and second, how to perform those tasks in terms of employing proper approaches.…”

Modern production, logistic and assembly systems comprise of a considerable number of processes which operate by using diverse types of resources. Conceptual design of these systems has become more complicated because of the large scale and multi-disciplinary essence of their design knowledge. This paper proposes a modelling framework to support the conceptual design of such systems. The framework employs the principles of system engineering to fulfil the necessity of having a multi-disciplinary approach for the design of such systems. The framework realizes the essence of holistic design by modelling the structural and behavioral aspects of a system in one design artefact. Object Oriented (OO) method is employed to facilitate the complexity of holistic analysis and yielding proper logics for system architecting. This paper proposes incorporating the OO analyzing semantics into Finite State Machine formalism. Therefore, the logical architecture will be established in an FSM platform. In return, the resultant artefact can stand as an executable Meta-Architecture such that design alternatives are its instances. Moreover, the Meta-Architecture enables simulation of the alternatives which serve their early validation. Accordingly, this approach opens avenues regarding incorporation of the Meta-Architecture with computational and analyzing methods which can significantly support the decision making in the conceptual design stage.

“…The standardization is somehow a measure of the maturity, widely expansion and growing acceptance of a given field and, in this sense, Systems Engineering is still a newborn area with a lack of accepted definitions and metrics (Valerdi & Davidz 2009 The first standards in the SE field have risen from the American military and aerospace industries, in the 1970s and 1980s, and were dedicated to the engineering process or, in other words, to the "WHAT" activities are to be performed. A process is a set of interrelated activities which transform inputs into outputs (Cloutier & Verma 2007). Since then, there has been an effort to take these standards to be domain independent in order to be applicable across different sectors, and to be international.…”

“…The Architecture Frameworks (AF) is one of those groups, which includes the standard frameworks that have been developed to support systems' (and software) architecting. According to Cloutier & Verma (2007), a framework is a logical structure or an organizational skeleton used to classify concepts, terminology, data, artifacts, etc. This tool, for structuring and integration, provides generic guidance for designing the architecture of a system that is, "the fundamental organization of a system, embodied in its components, their relationships to each other and the environment, and the principles governing its design and evolution" (IEEE 2000).…”

This paper addresses the present-day context of Systems Engineering, revisiting and setting up an updated framework for the SIMILAR process in order to use it to engineer the contemporary systems. The contemporary world is crowded of large interdisciplinary complex systems made of other systems, personnel, hardware, software, information, processes, and facilities. An integrated holistic approach is crucial to develop these systems and take proper account of their multifaceted nature and numerous interrelationships. As the system's complexity and extent grow, the number of parties involved (stakeholders and shareholders) usually also raises, bringing to the interaction a considerable amount of points of view, skills, responsibilities, and interests. The Systems Engineering approach aims to tackle the complex and interdisciplinary whole of those socio-technical systems, providing the means to enable their successful realization. Its exploitation in our modern world is assuming an increasing relevance noticeable by emergent standards, academic papers, international conferences, and post-graduate programmes in the field. This work aims to provide "the picture" of modern Systems Engineering, and to update the context of the SIMILAR process model in order to use this renewed framework to engineer the challenging contemporary systems. The emerging trends in the field are also pointed-out with particular reference to the Model-Based Systems Engineering approach.
