About The Customer
Trenitalia is the primary railway operator in Italy, responsible for managing the development, construction, and maintenance of the rail transportation system in the country. The company's Technical and Research Department uses advanced technology for design optimization, stress strength structural checks, and maintenance engineering planning for the Trenitalia fleet. The department works in collaboration with the Information Technology Department to improve mechanical stress simulation capability and efficiency, and to overcome challenges related to model size, solution times, and hardware architecture bottlenecks.
The Challenge
Trenitalia, the Italian railway operator, was facing challenges in managing the development, construction, and maintenance of the rail transportation system in the country. The Technical and Research Department of Trenitalia was using ANSYS Mechanical for design optimization, stress strength structural checks, and maintenance engineering planning. However, the need for larger analysis models and shorter computer response times led Trenitalia to evaluate new calculation solutions. The primary issues they had to overcome included limitations in model size due to the amount of real memory used by 32-bit finite-element programs, long solution times resulting from using a single-processor platform, and hardware architecture bottlenecks in memory and storage sub-systems that increased elapsed solution times. To address these issues, Trenitalia began investigating 64-bit technology, with efficiency requirements suggesting a scalable SMP architecture.
The Solution
Trenitalia evaluated the x86-64 technology of the PC-based AMD™ 64/EM64T systems to address their challenges. The AMD processors yielded good mathematical results, and full-duplex star topology workstation platforms moved gigabytes of data to/from memory and storage subsystem. A benchmarking study using ANSYS Mechanical to solve some real production test models led to the selection of the Microsoft® Windows x64 Edition operating system because of its solution speed and performance efficiency. A native 64-bit version of ANSYS for Windows x64 provided the analysis software needed for a two-way Win x64 SMP workstation able to support at least 16 gigabytes of memory with low-latency memory and storage subsystem. The success in efficiently solving million-degree-of-freedom models is attributed in particular to the ANSYS parallel compliant high-performance sparse solver.

IoT System for Tunnel Construction
The Zenitaka Corporation ('Zenitaka') has two major business areas: its architectural business focuses on structures such as government buildings, office buildings, and commercial facilities, while its civil engineering business is targeted at structures such as tunnels, bridges and dams. Within these areas, there presented two issues that have always persisted in regard to the construction of mountain tunnels. These issues are 'improving safety" and "reducing energy consumption". Mountain tunnels construction requires a massive amount of electricity. This is because there are many kinds of electrical equipment being used day and night, including construction machinery, construction lighting, and ventilating fan. Despite this, the amount of power consumption is generally not tightly managed. In many cases, the exact amount of power consumption is only ascertained when the bill from the power company becomes available. Sometimes, corporations install demand-monitoring equipment to help curb the maximum power demanded. However, even in these cases, the devices only allow the total volume of power consumption to be ascertained, or they may issue warnings to prevent the contracted volume of power from being exceeded. In order to tackle the issue of reducing power consumption, it was first necessary to obtain an accurate breakdown of how much power was being used in each particular area. In other words, we needed to be able to visualize the amount of power being consumed. Safety, was also not being managed very rigorously. Even now, tunnel construction sites often use a 'name label' system for managing entry into the work site. Specifically, red labels with white reverse sides that bear the workers' names on both sides are displayed at the tunnel work site entrance. The workers themselves then flip the name label to the appropriate side when entering or exiting from the work site to indicate whether or not they are working inside the tunnel at any given time. If a worker forgets to flip his or her name label when entering or exiting from the tunnel, management cannot be performed effectively. In order to tackle the challenges mentioned above, Zenitaka decided to build a system that could improve the safety of tunnel construction as well as reduce the amount of power consumed. In other words, this new system would facilitate a clear picture of which workers were working in each location at the mountain tunnel construction site, as well as which processes were being carried out at those respective locations at any given time. The system would maintain the safety of all workers while also carefully controlling the electrical equipment to reduce unnecessary power consumption. Having decided on the concept, our next concern was whether there existed any kind of robust hardware that would not break down at the construction work site, that could move freely in response to changes in the working environment, and that could accurately detect workers and vehicles using radio frequency identification (RFID). Given that this system would involve many components that were new to Zenitaka, we decided to enlist the cooperation of E.I.Sol Co., Ltd. ('E.I.Sol') as our joint development partner, as they had provided us with a highly practical proposal.

Airport SCADA Systems Improve Service Levels
Modern airports are one of the busiest environments on Earth and rely on process automation equipment to ensure service operators achieve their KPIs. Increasingly airport SCADA systems are being used to control all aspects of the operation and associated facilities. This is because unplanned system downtime can cost dearly, both in terms of reduced revenues and the associated loss of customer satisfaction due to inevitable travel inconvenience and disruption.

Vehicle Fleet Analytics
Organizations frequently implement a maintenance strategy for their fleets of vehicles using a combination of time and usage based maintenance schedules. While effective as a whole, time and usage based schedules do not take into account driving patterns, environmental factors, and sensors currently deployed within the vehicle measuring crank voltage, ignition voltage, and acceleration, all of which have a significant influence on the overall health of the vehicle.In a typical fleet, a large percentage of road calls are related to electrical failure, with battery failure being a common cause. Battery failures result in unmet service agreement levels and costly re-adjustment of scheduled to provide replacement vehicles. To reduce the impact of unplanned maintenance, the transportation logistics company was interested in a trial of C3 Vehicle Fleet Analytics.
