It is considered to be open, modularized, distributed, configurable, interoperable and maintainable. After introducing some core techniques of J2EE as the basic foundations of the proposed MES, this paper briefly analyzes the MES domain in manufacturing systems and constructs the abstract object and component model, and then establishes the MES architecture. This MES can be facilely integrated with other manufacturing applications. Finally, an example of integration with the enterprise resource planning (ERP) system is given.展开更多

Designing environment, designing method and the main modeling components of virtual MMW radiometer are researched. Important external parameters, which have significant influence to composing system, are used to components modeling, and then components are taken to buildup virtual MMW radiometer system. Moreover, the effect to output is contrasted whether there is a low-noise amplifier or not.展开更多

This procedure reduces the complexity and improves the reuse of the developed products. MDE （model-driven engineering） is a recent initiative that adopts this approach. In this context, model composition has become an important artifact in the MDE domain that allows constructing and composing an efficient assembly process. This paper will attempt to identify the strength and the drawbacks of the existing composition model paradigms, and determine the various parameters that govern their behavior.展开更多
