Visual simulation objects (VSO) is a collaborative architecture specification, design and execution toolkit that assists analysts in rapidly prototyping system designs and evaluating their dynamic performance. VSO uses a graphical simulation language to describe objects and their interactions. It can be used both for individual applications and in a collaborative development environment. VSO can translate architectures developed in a variety of languages, such as system architect, to VSO's format and execute them in a distributed environment using a built-in HLA interface. We demonstrate how two teams, initially working independently, can collaborate to build and execute a complex architecture and extract performance information from it. The first team translates an air operations center (AOC) model developed in system architect to VSO's format and executes it to determine its dynamic properties. The second team develops an executable architecture of time critical targeting (TCT), a U.S. Air Force war fighting function, in VSO. Working collaboratively, the two teams integrate their architectures in VSO via an HLA/RTI. The integrated architecture describes multiple simultaneously-executing target acquisitions, each of which sends a detection message to the AOC, and can be used to examine how AOC resources can be allocated to meet the targeting requests","PeriodicalId":283620,"journal":{"name":"Proceedings of the 2005 International Symposium on Collaborative Technologies and Systems, 2005.","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133536645","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}

VCampus provides a realistic-rendering of the university and allows users to obtain useful information such as building names and directories, university historical and statistical data, events scheduled to take place on campus, and area maps centered on specified locations. The users can navigate through the 3D representation of the campus by adopting either a first or a third person view and by selecting either a walking or a flying exploration mode. Various graphical objects can be accessed in the environment to obtain orientation data and general information, a guided tour is available, and communication and collaboration with peers is supported by a multi-user, multi-character real-time interaction facility.

Current implementation of MASSE is described in this manuscript, and its usefulness is shown in three aspects: simple accommodation of existing simulators, satisfactory performance for adopting grid computing technique, and systematic data analysis tool.
