As the Toyo Seikan Group's network grew, the cost and complexity of network connections between the Group companies increased, while the lead time required to incorporate new companies or change network settings grew longer. To solve these problems, the Toyo Seikan Group turned to NEC to help build an integrated, cost-effective WAN. Using SDN, NEC was able to successfully integrate the Group's WANs, as well as its frewalls. This paper introduces NEC's SDN solutions by examining the case of the Toyo Seikan Group WAN. Source

Parallel Quiet Acoustic guides system (PQuA) with a digital signage enables people to effectively acquire adequate information for a short time on the way to the destination. We ensured that most users could simultaneously catch two voice explanations among three voice explanations based on the packaging method of a long sentence and synchronization method for removing duplication of voice guides. Most users could also simultaneously catch two short voice explanations of about 50 words without synchronization. We also discuss how a user utilizes his/her two ears in order to simultaneously listening to two voice explanations that come from different directions. © 2011 Springer-Verlag. Source

The optimization of spare parts inventories is an issue that is commonly found in the manufacturing industry. NEC Fielding, who are the subsidiary of the NEC Group and manage the maintenance business, also have similar concerns, because traditional statistical techniques have had limited accuracy in predicting the future demand for repair parts. The company therefore has decided to adopt NEC's big data analysis technology "heterogeneous mixture learning." This has enabled them to forecast demands with high accuracy. They have thereby succeeding in reducing by about 20% the inventory of the high-rotation parts that occupy a large share of the spare parts shipments. As the stockout risk is also estimated, this approach has allowed the company to challenge a more thorough optimization of the inventory. This paper describes the spare parts demand forecasting procedures performed at NEC Fielding by using the heterogeneous mixture learning engine and includes discussion of its resulting effects.

Ever since the Great Tohoku Earthquake, energy saving on the part of businesses has become an urgent task in Japan. And increasingly more attention is being focused on the office, where energy-saving measures have taken longer to adopt. This paper introduces the SaaS type service "EnePal Office" which supports energy-saving at offices that are lagging behind, by not only applying "Visualization" to office energy consumption but also by providing a Navigation System to help save energy.

Trends in the usage of open system architectures and increasing system complications have been making it more difficult than hitherto to identify which device is faulty, the location of the problem and whether it is due to a hardware or software malfunction. Meanwhile, in order to enable stable system operation, it is essential to administer/ manage the entire system and this is only possible by managing the configuration, performance and resource information of the system. This paper introduces the remote functions packaged in NEC products that have been designed to meet the above needs. The present status and future deployment of remote maintenance utilizing the TRS (Total Remote Support) infrastructure is also discussed. Source
