This paper proposes a Python-based infrastructure for studying the characteristics and behavior of families of systems. The infrastructure allows automatic execution of simulation experiments with varying system structures as well as with varying ...

This paper proposes the Ontology for Healthcare Systems Modeling and Simulation (O4HCs), a domain analysis model based on System Entity Structure (SES), which includes the macro level facets that properly organize the healthcare system domain and ...

The System Entity Structure (SES) is a high level approach for variability modeling, particularly in simulation engineering, which is under continuous development. In this context, an enhanced framework is introduced that supports dynamic variability ...

System inference, i.e., the building of system structure from system behavior, is widely recognized as a critical challenging issue. In System Theory, structure and behavior are at the extreme sides of the hierarchy that defines knowledge about the ...

The modeling and simulation M&S of complex systems often requires models described at different levels of detail characterized by differences in abstraction hierarchies and/or time granularity. The discrete-event system specification DEVS is a framework ...

The increasing complexity of systems entails an increasing complexity of simulation models. Likewise, heterogeneity in system components corresponds to heterogeneous simulation models. Cyber physical systems CPS represent an emerging class of technical ...

Software product-lines are designed to tackle the development of systems that are characterized by a high degree of variability. They define variation points where different solutions can be derived for different products. Such variability mechanisms ...

Discrete Event System Specification theory has been applied to diverse domain areas with specific computer languages. MS4 Me software is based on Java for DEVS Modeling and Simulation (M&S). However, it provides Meta DEVS models called DEVS Natural ...

In modeling and simulation, Validation and Verification (V&V) have always attracted significant interest. With Model Based Development (MBD) testing models became a part of product V&V. Model-Based Testing (MBT) is an advanced approach for automating ...

We describe how to develop a suite of models in the MS4 Modeling Environment. The approach employs the operation of merging of System Entity Structures supported by the environment. After construction, the suite of models can be hosted on Model Store, ...

Today's complex technological systems cater to a wide variety of stakeholders and their construction involves a multitude of development disciplines. This paper reports on the design of a Modeling Support Environment (MSE) intended to support a large ...

System complexity in military applications requires interoperation between Live and Virtual models. The network middleware enables heterogeneous systems to exchange information. Data Distribution Service (DDS) is a network middleware that uses the ...

Korean distribution industry companies and organizations have taken up EDI(Electronic Data Interchange) for enhancing air distribution process efficiently. However, they are facing up problems in utilizing air EDI because of some reasons hard to ...

As a networkâ s uses, and especially the number of internet users, increases rapidly, an efficient system for managing large-network traffic datasets becomes an important issue. Although there are several network traffic analysis tools, such as tcpdump, ...

An experimental frame is a specification of the condition under which the system is observed or experimented with. This paper presents experimental frame structuring of the source data. US Climate Normals are introduced for the source data example. The ...

Hierarchical, modular specification of discrete-event models of fers a basis for reusable model bases and hence for enhanced simulation of truly varied design alternatives. We describe an envi ronment which realizes the DEVS formalism developed in ...
