With the development of computer, networking and automation technology, mining information technology becomes more intelligent and more integrated. This paper establishes a smart mine system in one mining enterprise of East China Mineral Exploration and Development Bureau. By adopting service-oriented architecture, smart mine system reuses the existing function modules and integrates the data through Web service to form a comprehensive servicesystem to solve information island problems, which helps to facilitate production, operation and management of mining enterprises.

Digital instruments and simulations are creating an ever-increasing amount of data. The need for institutions to acquire these data and transfer them for analysis, visualization, and archiving is growing as well. In parallel, networking technology is evolving, but at a much slower rate than our ability to create and store data. Single fiber 100 Gbps networking solutions have recently been deployed as national infrastructure. This article describes our experiences with data movement and video conferencing across a networking testbed, using the first commercially available single fiber 100 Gbps technology. The testbed is unique in its ability to be configured for a total length of 60, 200, or 400 km, allowing for tests with varying network latency. We performed low-level TCP tests and were able to use more than 99.9% of the theoretical available bandwidth with minimal tuning efforts. We used the Lustre file system to simulate how end users would interact with a remote file system over such a high performance link. We were able to use 94.4% of the theoretical available bandwidth with a standard file system benchmark, essentially saturating the wide area network. Finally, we performed tests with H.323 video conferencing hardware and quality of service (QoS) settings, showing that the link can reliably carry a full high-definition stream. Overall, we demonstrated the practicality of 100 Gbps networking and Lustre as excellent tools for data management. (C) 2012 Elsevier B.V. All rights reserved.

In view of the characteristics of the manufacturing enterprise's producer service value network, this paper constructs a service performance evaluation index system for the producer service value network. Considering the mutual influences and function relations among the evaluation indexes, this research selects the Analytic Network Process (ANP) to determine the weights of indexes, and uses the grey relational analysis to evaluate the service performance, and verifies the model through an application example.
