Model-Driven Design-Space Exploration for Software-Intensive Embedded Systems

“…Techniques to evaluate system performance come in many flavors. Basic estimations employ widely used and generic spreadsheets or other high-level models [1] and lead to extremely fast but often inaccurate results, viz., they are not well suited to capture the system dynamics that parallel processing and scheduling bring about [3].…”

Service-oriented systems are designed for interconnecting with other systems. The provided services face timing constraints, the so-called latencies. We present a high-level performance evaluation technique that can be used by a system designer to obtain distributions of these latencies. This technique is capable of capturing nondeterministic, probabilistic and real-time aspects in one go. Under the hood, the technique is equipped with two mechanisms: (i) selection of the right abstraction of the model (to prevent a state space explosion) by evaluating the performance of executing models of different complexities; and (ii) an efficient algorithm in which basic estimates, simulation, and (probabilistic) model checking are combined. We illustrate our approach with an case on image processing of interventional X-ray systems.

“…Table 4.1 summarizes a literature review of several simulation methodologies based on: (i) their purpose, (ii) the means with which they achieve this purpose, (iii) the main outcomes of using the methodology and (iv) the tools, languages and methods used. The selection of methodologies in Table 4.1 consists of: -Domain independent methodologies [Birta and Arbez, 2013, Boardman and Sauser, 2008, Browning et al, 2006, Law, 2014 -Systems engineering specific methodologies [Bjorkman et al, 2013, NASA, 2008, Ryan et al, 2014, Wang and Dagli, 2011 -Methodologies with a focus on the conceptual system design stage [Basten et al, 2013, Canedo and Richter, 2014, Topper and Horner, 2013, Yaroker et al, 2013 Many methodologies focus solely on later design stages. For example [Ryan et al, 2014] even mention:…”

“…This in turn allowed new procedures using 3D guidance to be developed. In the last decades, the flexibility that is exhibited by systems has become more and more realized by the software domain [Basten et al, 2013]. Two examples of this can be found in current interventional X-ray systems such as the Philips Allura system 1 .…”
