About The Customer
SMRT Trains Ltd is the first rail operator in Singapore, operating and maintaining over 282 kilometers of rail track since 1987. They strive to provide safe, convenient transportation services to their commuters. With an average daily ridership of over 2 million people in 2020, SMRT has a significant responsibility to ensure the reliability and safety of their rail network. They measure the system’s reliability using mean kilometers between failure (MKBF), where a failure is defined as a service delay of more than five minutes. To improve their reliability, SMRT set a target of 1 million MKBF for all their lines.
The Challenge
SMRT Trains, the first rail operator in Singapore, operates and maintains over 282 kilometers of rail track. With an average daily ridership of over 2 million people in 2020, SMRT needed a method to keep the tracks in good condition to avoid delays and ensure reliability. They measure the system’s reliability using mean kilometers between failure (MKBF), where a failure is defined as a service delay of more than five minutes. To improve their reliability, SMRT set a target of 1 million MKBF for all their lines. However, they were relying on intensive, time-consuming, and manual maintenance planning using tens of millions of data points per year across separate data silos. They needed to upgrade their legacy processes and improve their maintenance strategy.
The Solution
SMRT used Bentley’s AssetWise Linear Analytics as the basis of their predictive decision support system (PDSS). The PDSS was designed to create a data repository to centralize all the data completely and accurately, as well as a data analytics engine that can analyze the data for maintenance strategy recommendation, resource optimization, and improve maintenance effectiveness. The PDSS automatically runs every day to process the data and create a prioritization table. The AssetWise-based platform automatically pulled four years of SMRT’s data from asset configuration information, inspection records, and operating data. All this information is stored in the cloud via Microsoft Azure, with new information automatically imported into the system. This automation ensures that old data is regularly updated, creating a baseline to perform maintenance. Users can then validate the information before it gets used to alert engineers of relevant work activities.

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.

Digitize Railway with Deutsche Bahn
To reduce maintenance costs and delay-causing failures for Deutsche Bahn. They need manual measurements by a position measurement system based on custom-made MEMS sensor clusters, which allow autonomous and continuous monitoring with wireless data transmission and long battery. They were looking for data pre-processing solution in the sensor and machine learning algorithms in the cloud so as to detect critical wear.

Case Study
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.

3M Gains Real-Time Insight with Cloud Solution
The company has a long track record of innovative technology solutions. For example, 3M helps its customers optimize parking operations by automating fee collection and other processes. To improve support for this rapidly expanding segment, 3M needed to automate its own data collection and reporting. The company had recently purchased the assets of parking, tolling, and automatic license plate reader businesses, and required better insight into these acquisitions. Chad Reed, Global Business Manager for 3M Parking Systems, says, “With thousands of installations across the world, we couldn’t keep track of our software and hardware deployments, which made it difficult to understand our market penetration.” 3M wanted a tracking application that sales staff could use to get real-time information about the type and location of 3M products in parking lots and garages. So that it could be used on-site with potential customers, the solution would have to provide access to data anytime, anywhere, and from an array of mobile devices. Jason Fox, Mobile Application Architect at 3M, upped the ante by volunteering to deliver the new app in one weekend. For Fox and his team, these requirements meant turning to the cloud instead of an on-premises datacenter. “My first thought was to go directly to the cloud because we needed to provide access not only to our salespeople, but to resellers who didn’t have access to our internal network,” says Fox. “The cloud just seemed like a logical choice.”
