“…OWL-S (and WSMO) (Lara et al, 2004) provide generalized models for describing services. Others have identified the need for specialized common concepts within a web service context (Cardoso & Sheth, 2003;Dahmann & Morse, 1998;Lara et al, 2004;Paolucci et al, 2002), one example being quality of service. These concepts represent glue homogenizing a wealth of asymmetrically described web resources.…”

COTS simulation packages (CSPs) have proved popular in a wider industrial setting. Reuse of simulation component models by collaborating organisations or divisions is restricted however by the same semantic issues that restrict the inter-organisation use of other software services. Semantic models, in the form of ontology, utilized by a web service based discovery and deployment architecture provides one approach to support simulation model reuse. Semantic interoperation is achieved using domain grounded simulation component ontology to identify reusable components and subsequently loaded into a CSP, modified according to the requirements of the new model, and locally or remotely executed. The work is based on a health service simulation that addresses the transportation of blood. The ontology engineering framework and discovery architecture provide a novel approach to inter-organisation simulation, uncovering domain semantics and providing a less intrusive mechanism for component reuse. The resulting web of component models and simulation execution environments present a nascent approach to simulation grids.

“…Orthogonal to our work is the standardization of the interfaces for interconnecting simulation applications, a problem which has been addressed by the High Level Architecture (HLA) specification for simulation applications [25] and its updates. The federates model of the HLA specification allows for the coupling of different remote simulation applications developed by different organizations by implementing a federate interface.…”

Abstract-Computer simulation is an important factor in today's disaster prevention procedures. Simulation codes assess the evolution and impact of various physical phenomena in domains such as nuclear and environmental sciences, and ultimately help saving lives. However, new and more computationally demanding models, and new regulations for personnel training have increased the demand for computational power. While the existing simulation codes can be ported to computing environments that can meet the new demand, such as supercomputers, clusters, and grids, it is too expensive and time-consuming to rewrite and re-certify them. Instead, in this work we propose an aspect-oriented approach that takes existing simulation functionality and combines it with functionality required to run the simulation on different computing environments transparently to the simulation developer. Through experiments in the DAS-3 multi-cluster grid we show that our approach increases the reusability, the maintainability, the scalability, and the robustness of a real disaster prevention simulation, while incurring a low performance overhead.

“…Strong coupling requires relying on some kind of operational architecture or framework, which can provide a way to express the control over sub-models. This framework can either use an existing modeling paradigm (like Li et al, 2013, which proposes an "agent-centered" approach in which different modeling formalisms can be translated to individual or agent-based models) or make use of specialized software architectures dedicated to the functional coupling of models, like the High-Level Architecture (HLA; Dahmann and Morse, 1998;Hill, 2002;Kim, 2005;SISO, 2010), the Discrete Event Systems (DEVS Zeigler et al, 1997;Hild, 2000;Vangheluwe, 2000), of the Functional Mock-up Interface (Blochwitz et al, 2012;Bertsch et al, 2014). HLA is a standard and a software framework that has been originally designed as an infrastructure dedicated to the synchronization of simulators whenever they exchange data.…”

Coupling Environmental, Social and Economic Models to Understand Land-Use Change Dynamics in the Mekong Delta

The Vietnamese Mekong Delta has undergone in recent years a considerable transformation in agricultural land-use, fueled by a boom of the exportation, an increase of population, a focus on intensive crops, but also environmental factors like sea level rise or the progression of soil salinity. These transformations have been, however, largely misestimated by the 10-year agricultural plans designed at the provincial levels, on the predictions of which, though, most of the large-scale investments (irrigation infrastructures, protection against flooding or salinity intrusion, and so on) are normally planned. This situation raises the question of how to explain the divergence between the predictions used as a basis for these plans and the actual situation. Answering it could, as a matter of fact, offer some insights on the dynamics at play and hopefully allow designing them more accurately. The dynamics of land-use change at a scale of a region results from the interactions between heterogeneous actors and factors at different scales, among them institutional policies, individual farming choices, land-cover and environmental changes, economic conditions, social dynamics, just to name a few. Understanding its evolution, for example, in this case, to better support agricultural planning, therefore requires the use of models that can represent the individual contributions of each actor or factor, and of course their interactions. We address this question through the design of an integrated hybrid model of land-use change in a specific and carefully chosen case study, which relies on the central hypothesis that the main force driving land-use change is actually the individual choices made by farmers at their local level. Farmers are the actors who decide (or not) to switch from one culture to another and the shifts observed at more global levels (village, district, province, region) are considered, in this model, as a consequence of the aggregation of these individual decisions. The central component of our hybrid model is then an agent-based model of farmers, provided with a sophisticated mechanism of decision-making that is influenced, at different degrees, by their perception of the contexts in which they act or interact with other actors. The economic context, accessible by them through the market prices of crops, plays a role, as well as the changes observed or forecasted in their physical context (land-cover changes, salinity rise) or the decisions made by others in their social Coupling Environmental and Socio-Economic Models context (neighbors, family members, opinion leaders). The model of farmers is coupled, through this decision-making mechanism, with other independent sub-models, each of them carrying out a realistic description of one of these contexts. Since the dynamics depicted in these sub-models obey to different logics, operate at different scales and rely on different data, they are represented using appropriate modeling techniques: the spatial model is based on GIS information on parcels, soils, and ...
