Simulation supporting environment is the important part of simulation system. Different level requests variously to real-time behavior in the complex real-time simulation system. Under the Environment of RTX and Windows-NT, Performance index of Ethernet and reflective memory network including data transmission delay and delay jitter was measured. The(More)
Aiming at the deficiencies of the mature object-oriented simulation modeling method for Production System, the aspect-oriented extension of UML is completed based on the Senior Properties of UML extension mechanism. As an example of the typical maintenance cross-cutting concerns, the aspect-oriented modeling method of the production line simulation system(More)
To meet real-time requirements of communication between various testing entities, complex virtual testing system is constructed base on heterogeneous networks environment. Bridge method is the main approach for HLA-DIS inter-protocol connection. It solves the problems of interoperation but becomes the bottom-neck of the whole testing system. In application(More)
The major approaches to monitor the software environment is software sensor. This paper proposed a kind of software sensor, which is based on environment-aware. Considering the efficiency of the sensor monitoring, we made the identification of concern point and separation of aspects in avionics system, and carried out the aspects recombinant by software(More)
According to current certain disadvantage of Application of DIS, we built a DIS system on real-time Ethernet. According to characteristics of RT-TCP/IP environment, Object Interaction PDU was redesigned, four basic RT-PDU which include methods of create Object, delete object, execute object and modify the object property were built. Based on HLA data(More)
Interaction interface is an important concept in component-base software engineering. In this paper, an interface-component based software analysis and design method is proposed,which is characterized by interface-based requirement analysis and interface-based design. It includes mainly three steps:(1)Capture and formally describe the interfaces from(More)
Communication and information services are the important parts of virtual test systematic supporting environment. With the background of a military virtual testing system, we have achieved a virtual testing platform for communication based on RT-TCP/IP and real-time database technology. In the communication level, we analyzed the real-time performance of(More)
