Object-Oriented Comodeling Methodology for Development of Domain Specific DEVS Models
Published in Gabriel A. Wainer, Pieter J. Mosterman, Discrete-Event Modeling and Simulation, 2018
The simulation interoperation layer is required only when the simulator should be part of a distributed simulation. A stand-alone simulator that consists of the lower three layers quickly turns out to be interoperable when simply adding the simulation interoperation layer. This layer consists of two parts: High Level Architecture (HLA)/Run-Time Infrastructure (RTI) for external interoperation, and internal protocol conversion for underlying the DES simulation layer. The HLA/RTI is good for interoperation with other simulators. The HLA/RTI, however, does not suffice for this layer because it does not contain any specification for simulation algorithms. The layer requires a specific protocol conversion from HLA/RTI to the underlying DES simulator layer. The DES simulation layer and simulation interoperation layer are beyond the scope of this chapter because it does not affect the cooperation between domain engineers and M&S engineers.
Hybrid Systems Dynamic, Petri Net, and Agent-Based Modeling of the Air and Space Operations Center

The operator–environment model is the focus of this chapter. AnyLogic® was selected as the software environment in which to build the agent- based model; this environment can support multiple modeling paradigms in the same tool, thus addressing the difficulty in linking the models. AnyLogic has the following features that facilitate multiscale hybrid modeling: Supports system dynamics, discrete- event, agent- based, and dynamic systems modeling while using the same timing engineMaintains discrete or continuous spaceEasy to adjust the level of abstractionPossible to choose the best approach for the problemEasy to switch from one approach to anotherEasy to mix approaches to develop better modelsBased on Java, object- orientedViewer/ debugger, stand- alone Java application, Java applet, XML format Java remote method invocation (RMI), high- level architecture (HLA)

Another consideration when adapting IOS technology to other environments is definition of the appropriate protocols (i.e., mechanisms for communication and sharing of network data). With respect to LVC environments, there are currently established protocols in place for live training (i.e., Test and Training Enabling Architecture, TENA) and others in place for virtual and constructive environments (i.e., Distributed Interactive Simulation, DIS; High Level Architecture, HLA). However, it will be necessary to consider either extensions to these existing protocols or new protocols to support sharing information across these environments. While portals and gateways assist with translation between standards, they can add complexity to the network, inconsistencies between standards, safety issues, simulation artificialities, and fair fight/ability to calculate performance.
A survey of semiconductor supply chain models part I: semiconductor supply chains, strategic network design, and supply chain simulation

Distributed simulation approaches represent another stream of research in which detailed simulation models of individual facilities in a semiconductor supply chain are connected by the High Level Architecture (HLA) (cf. SISO, IEEE 2016) that provides a run-time infrastructure (RTI) ensuring their interoperability. Lendermann et al. (2003) and Chong et al. (2006) discuss distributed simulation models of simple semiconductor supply chains. Gan et al. (2007) use the HLA to analyse a ‘borderless’ fab scenario where two fabs are located close to each other and specific process steps of some lots can be performed in the neighbouring fab, focusing on the impact of different lot batching sizes for the cross-fab process step on lot transfer frequency and cycle time.
