With the rapid development of new Information Technology(IT), big data platform technology has been one of the important supporting technologies of modern modeling simulation field. On the basis of the current situation and research of big data applications, the architecture of big data supporting platform was proposed, and its application mode, big data application standard, big data storage, big data analysis, and some related technologies were researched and summarized. The applications and development of big data platform were discussed.

In order to solve the problem that the heterogeneous knowledge in aircraft design is difficult to share, reuse and support to reason each other, a ontology model of knowledge, based on the unified description framework, was proposed. Firstly, the formats of representation for all kinds of knowledge in aircraft design knowledge were studied, and then a unified description framework for this knowledge was proposed. Secondly, the ontology model of knowledge was studied. In this model, basic cell for modeling was defined, which could be used to modeling directly. At last, an example, modeling of pneumatic knowledge in aircraft design verified the validity of the modeling method in this paper.

To meet the requirement of simulation resource description dynamical management by the technology of simulation system environment dynamically building in Cloud Simulation Platform(CSP), the application of dynamical management based on ontology-based simulation case-based description and reasoning has been presented. This method could generate description intelligently, when simulation users cannot give the exact one, so as to provide the basis for dynamical building in CSP. With the CBR, the paper mainly discussed the ontology-based expression and reasoning. Finally, the description of simulation case and the ontology-based reasoning rule are present to show the feasibility and effectiveness.

Through analysis and evaluation of water consumption on-site survey of near 200 large public buildings, the necessity of the application and discussion of internet of things on wireless remote transmission of water consumption data and subentry measure are discussed. This paper advances the program of wireless remote monitoring system based on internet of things, which not only provides the ways to obtain data foundation for government policy decision by internet of things on wireless remote transmission, but finds the method and potential for energy-saving. At the same time, it can implement the development of internet of things and come up to the aim of energy-saving based on internet of things. (C) 2011 Published by Elsevier Ltd.
