Extending Design Capabilities of SysML with Trade-off Analysis: Electrical Microgrid Case Study

Automated Component‐Selection of Design Synthesis for Physical Architecture with Model‐Based Systems Engineering using Evolutionary Trade‐off

“…The main objective to use the OMG SysML TM is to define the system specifications. Since the safetycritical systems like those of a passenger car and an airplane are very complex, they all require a welldefined specification before the design and development (Spyropoulos & Baras 2013). Meanwhile, industries still need to decide faster without much modeling effort (Trcka et al 2011).…”

SysML Modeling for Embedded Systems Design Optimization - A Case Study

“…However these approaches lack support of multi-criteria optimization that help designers to perform design space exploration and trade-off analysis. The approach proposed by P. Van Huong [3] and Spyropoulos [4] allows the user to perform multiple analyses in the same environment. These approaches are adapted to the component parameters optimization like CPU frequency or memory size, not to the architecture composition and redundancy problem we want to address.…”

“…By contrast, little work has been published on SysML modelling as a front-end to come up and compare different design alternatives. Current approaches such as [3] and [4] address design optimization from SysML models but differ from our approach by focusing on component parameters tuning, like CPU frequency or memory size. In our work we propose to take into account the hardware component selection, the component redundancy level and the component connection, in order to optimize the system cost and reliability.…”

Encoding Technique of Genetic Algorithms for Block Definition Diagram using OMG SysML™ Notations

“…Systems have become more complex than they used to be. The increasing number of components, functions, and interfaces are cross-multidisciplinary (Crowder, Carbone & Demijohn 2016) (Mhenni 2014) in an open system and unpredictable circumstances (Spyropoulos & Baras 2013). The systems engineering challenge is to manage the complexity, communication among disciplines, systems integration, and especially in a trade study analysis for component selection.…”

“…Since the OMG SysML™ structure model is not made from simple numeric or string values, the relationships of its subsystems and parameters cannot be fully recognized by the genetic algorithm. To solve the problem, formal and rigorous reasoning to OMG SysML™ block definition diagram (BDD) is needed (Lima et al 2016) (Spyropoulos & Baras 2013). The OMG SysML™ requires a precise and a well-defined formal semantics (Lima et al 2016).…”
