The `Systems Engineering' (SE) approach is currently changing the design and development of industrial product being manufactured through a direct processing of materials. Its influence upon the ...machine and system design activity is herein analyzed, by focusing on the integration of functional and physical models. Assessing a suitable tool to predict the system performance through a heterogeneous simulation is a main goal of the research activity. As an example of application a flywheel system for the kinetic energy storage is used to describe some typical features of this technical domain.

The application of tool integration in an industrial use case in the context of the CRYSTAL European project is presented. In particular, the development of a connecting application conceived to ...provide interoperability between two tools used in the Model-Based design and analysis of aircraft systems is described. The main goal behind this activity is allowing different specialists to use several tools for each specific task, in the context of a seamless Model-Based design process. A practical application of OSLC is proposed to face this problem within an industrial scenario. The work showed that the standard can promisingly address interoperability issues although the tools still provide limited OSLC support.
The dependability analysis is crucial for a wide range of systems. It becomes even more difficult to assess when dealing with cyber-physical systems (CPSs), being resulting as an integration of ...physical and cyber parts, strongly interacting to provide a service or a function. In this context, the dependability analysis of a Deicing System (DS), which aims at preventing or decreasing the ice accretion on safety critical components of the aircraft, is experimented by exploiting the RAMSAS method, i.e. a novel model-based method to support the dependability analysis of systems. It allows the evaluation of dysfunctional behaviors of systems, through some available modeling practices combined with simulation techniques. Specifically, this paper aims at virtually assessing the design process of the DS by flexibly evaluating its performances, in terms dependability indices, through the exploitation of RAMSAS. Furthermore, it supports the engineers to compare different design choices as well as to guide them for selecting and integrating properly system components before its actual realization.
The design of a Control Maintenance system (CMs) for an airborne platform deeply deals with the mission, the on-board systems interfaces and the identification of their behaviour in operation. This ...paper describes how the Model Based Systems Engineering (MBSE) was applied to an industrial test case to perform the functional design of an innovative CMs to be integrated with the aircraft Fuel system (Fs). The impact of different approaches applied when modelling the two systems and their integration through the SysML was investigated. As the IBM Rational Rhapsody® tool was used, the Harmony® methodology was applied to the CMs, while a MBSE customized approach was implemented for the Fs, even to cope with some differences in coupling an avionic system to a physical one.
