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...
Much as Edgar Dijkstra in 1968 observed the dangers of relying on the "go to" statement, the authors of this article observe the detrimental effect of overreliance on quantitative simulators. Over time, simulator tools have become more complex and sophisticated. While this seems beneficial, new generations of simulators are built with easily abused modeling abstractions, some with poorly...
Safety-Critical systems, as used in the automotive, avionics, or aerospace domains, are becoming increasingly software-reliant to the extent that the system cannot function without the software. On one hand the software system provides an integrated set of functionality to operate the system and manage failure and unsafe conditions. Current best safety engineering practices, such as DO178B/C or SAE...
The simulation system theory is one of the basic theories of the discipline of simulation science and technology. The paper analyzes the constitution of the simulation system theory from three different levels, that is, the general theory, the domain theory and the supporting technologies for constructing simulation systems. It proposes that the general theory of simulation systems include the definition...
The Department of Electronic Engineering of Beijing Institute of Technology is integrating emerging interconnect technologies with other high-performance technologies to meet the demanding requirement of future, real-time signal processing applications. For next-generation, scalable, modular and adaptable signal-processing system, a universal, flexible and high-performance signal processing module...
Requirements modeling has been recently introduced in the UML world with the form of a new profile called SysML. This paper explores the possibility to link concepts used to describe requirements with those of the enterprise language of RM-ODP. Some correspondence rules are proposed and illustrated on a case study.
