In a distributed simulation of highly interacting system models, the main bottleneck may become the communication and synchronization required to maintain the causality constrains between distributed model components. We designed and implemented the ARTÌS middleware as a new framework incorporating a set of features that allow an adaptive optimization of the communication layer management in a distributed simulation scenario. ARTÌS has been integrated with GAIA, a dynamic mechanism for the runtime management and adaptive allocation of model entities in a distributed simulation. By adopting a runtime evaluation of causal bindings between model entities GAIA adapts the dynamic and time-persistent causal effects of model interactions to dynamic migration of model entities. Preliminary results demonstrate that the combined effect of ARTÌS management and GAIA heuristics leads to a significant reduction in the communication and synchronization overheads between the physical execution units. Simulation performance enhancements have been obtained also in worst-case modelling assumptions and simulation scenarios.","PeriodicalId":355772,"journal":{"name":"Eighth IEEE International Symposium on Distributed Simulation and Real-Time Applications","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127315251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is important that allowance is made for maintenance activities during a products design phase to help reduce the lifetime operating costs of such large scale mechanical products. Unfortunately, current CAE systems do not support such assessment capabilities, with these issues typically being addressed using expensive and time consuming physical prototypes. The design and implementation of an immersive virtual prototyping environment for supporting the assessment of assemblability and maintainability of large scale mechanical products, along with its use as a maintenance training tool will be outlined. Procedures and environments for realistic component assembly, constraint recognition, automatic disassembly sequence generation, and maintenance review and training are presented. The simulation of maintenance operations allows for maintenance to be addressed early in the design stages. This reduces unforeseen problems creeping into the design as it progresses through its life cycle, consequently saving both time and money while improving product quality.","PeriodicalId":355772,"journal":{"name":"Eighth IEEE International Symposium on Distributed Simulation and Real-Time Applications","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123089874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
