Crew scheduling is an NP-hard constrained combinatorial optimization problem, which is very important for the airline industry. We propose a genetic algorithm, GraGA, to solve this problem. A new graph based representation utilizes memory effectively, and provides a framework in which we can easily develop various genetic operators.

The process of integrating DoD Modeling and Simulation paradigms around the new HLA/RTI standards proceeds in parallel with the onset of new Object Web standards for distributed objects and componentware, emergent at the crossroads of CORBA, DCOM, Java, and XML based distributed object technologies. We describe here our WebHLA approach which integrates both trends by offering Object Web based implementation of the HLA framework. See http://surface.syr.edu/npac/70/

This paper presents an approach to the next generation of televirtual (TVR) environments that integrate collaboration with distributed computing and modern modeling and simulation technologies. It follows a three-tier architecture with Web Object (Java/CORBA) based middleware, VRML/Java3D/DirectX based front-ends, and JDBC/PSS/OLEDB based back-ends. It also tests the design and integration concepts that it mentions by prototyping a multi-user authoring and runtime environment, in order to support WebHLA-based, distributed military simulations. The paper lists a taxonomy of collaboratory frameworks and presents an integration paradigm, based on the WebFlow system at the Northeast Parallel Architectures Center (NPAC).

We review the growing power and capability of commodity computing and communication technologies largely driven by commercial distributed information systems. These systems are built from CORBA, Microsoft’s COM, JavaBeans, and rapidly advancing Web approaches. One can abstract these to a three-tier model with largely independent clients connected to a distributed network of servers.

We are discussing the four major standard candidates for distributed object/componentware computing: Java, CORBA, COM and WOM within our proposed coordination framework we call Pragmatic Object Web (POW). We describe our integration approach based on multi-protocol middleware server JWORB (Java Web Object Request Broker) that currently integrates HTTP and IIOP and which we now further develop to also support COM and WOM core functionalities. We are also experimenting with visual data ow authoring front-ends using NPAC WebFlow system on top of JWORB based software bus. Finally, we illustrate our technologies in one major application domain- DoD Modeling and Simulation- where we use JWORB to implement the Real-Time Infrastructure (RTI) layer of High Level Architecture (HLA). HLA was recently specified by DMSO as a general integration framework for DoD distributed simulations and we claim that we can bring it to a broader community of distributed collaborative object/componentware computing via the interactive Web/CORBA/Java/COM interfaces of our Pragmatic Object Web.

We present here our Pragmatic Object Web based approach to High Performance Modeling and Simulation and we describe the associated middleware software recently prototyped at NPAC: JWORB (Java Web Object Request Broker) which integrates HTTP and IIOP protocols, and Object Web RTI which implements DMSO RTI 1.3 on top of the JWORB based CORBA / Java software bus. We explain how JWORB and OW RTI are used to build WebHLA – an interactive FMS training environment and we outline our plan towards WebHLA based Virtual Prototyping Environments for Testing, Evaluation and Simulation Based Acquisition.
