While Systems Engineering has come a long way since its early beginning over six decades ago, it is still facing challenges in gaining the same degree of rigour and precision that is found in the theorical foundation of other engineering domains. Systems Engineering has always incorporate tools and methods from other engineering domains and adapted them to fit the purpose of engineering systems. This...
Computer Diagrams are the communication mechanism among the different stakeholders of the software development lifecycle. While they are though at school, and promoted to be used by students for current and future projects, we still do not see full adoption in real life context. The literature reviewed points out some reasons related to this issue and propose some solutions, but still the problem...
Combat system effectiveness simulation (CESS) is a special type of complex system simulation. Three non-functional requirements (NFRs), i.e. model composability, domain-specific modeling, and model evolvability are gaining higher priority from CESS users when evaluating different modeling methodologies for CESS. Traditional CESS modeling methodologies are either domain-neutral (lack of domain characteristics...
This paper deals with advantages of model-based software engineering approach of critical UAV onboard systems. Application of modern model-based technologies for critical onboard systems development is considered. Rules for critical software engineering at all life cycle stages are defined by functional standards. Mentioned approach implements all requirements of safety standards by automating the...
Today cloud computing has become one of the common technologies that most of the companies want to migrate their legacy systems or deploy their new system to it. Besides modeling the system, software designers need to model the deployment infrastructure, which their system will be deployed on it. In this paper first of all we presented and categorized the requirements of modeling cloud and then illustrated...
Although building quality into software is paramount, professionals find that testing is necessary to assure that the system will operate as desired. Developing tests can take significant resources. In 1998, NIST showed how tests can be automatically generated from models using model checkers and specification mutation. This was an early result in what is now a broad area known as "model-based...
This paper recommends practices for development and deployment of modeling, simulation, and analysis (MS&A) tools for homeland security applications. The proposed set of recommended practices applicable to any MS&A application includes: software engineering practice/ software reliability, modeling practice, model confidence/ verification, validation and accreditation, standards, interoperability,...
Market trends for applying ldquoSystems of Systemsrdquo (SoS) compels developers who want to advance their business to be involved in SoS programs. Although the difficulties and challenges entailed in developing SoS are numerous, the integration of varied technologies into coherent systems, interconnected in a network, brings with it an immense potential for creating new spin-off products with correspondingly...
An ongoing proliferation of so-called maturity models promises no end in sight for the development of new ones. Such models cover the entire spectrum of IT activity, from enterprise architecture to software development. The majority of these variants do not have associated assessment models. Consequently, these models' primary purpose is to be informative rather than normative in the sense of being...
