Taming the Data Monster

May 9, 2016
With the right strategy and tools, you can master your data and put it to work improving business performance.

Factories today are smarter than ever before. Intelligent motors, smart drives, safety PLCs, sensor networks¾the connected devices in the industrial Internet of Things are on track to reach 48.2 billion installed by 2025. Much of the value of these devices lies in their ability to communicate, delivering frequent updates about their status, performance, and availability. They generate vast amounts of data, the majority of it a variations on "I'm fine, I'm fine, I'm truly fine, I'm very fine, I’m oh so fine, thanks for asking.” As with those 1950s creature features with ants the size of pickup trucks, something easily managed when it's small can be downright monstrous when it gets too big. That onslaught of data from the production floor can attack your budget, piling up charges for engineering hours, storage hardware, energy to run that hardware, space for the hardware, and network bandwidth.

The sheer volume also introduces the risk that all of those messages (“I’m still fine”) will overshadow an anomalous reading that might otherwise allow you to catch a fault before it happens. Fortunately, a careful data strategy coupled with visualization tools can help you tame the data monster and convert all of those bits and bytes into actionable insights.

Have a Plan

The first step in taming the data monster is to avoid creating the monster in the first place. Although it can be tempting to monitor everything you can in the spirit of keeping your options open, that approach is counterproductive. It’s better to begin with a single issue, identify the data necessary to address it, and craft a solution. Maybe the goal is to track energy consumption for each machine or to compare operational equipment effectiveness (OEE) from facility to facility. By executing your initial project, you and your team will learn the process. You’ll develop the skill set necessary to attack future problems, because solving one issue inevitably leads to identifying new ones.

Visualization applications are aimed at distilling down masses of data and making it consumable by the greatest number of job roles throughout the organization. To fulfill that task, first and foremost it needs to capture input in quasi-real time from assets across the enterprise. In addition to manufacturing equipment, the system should be able to monitor support systems like cooling towers, chillers, boilers, and air-handling units.

The goal is to uncover hardware, production, and supply-chain trends that can be used to optimize performance at all levels. Fault-detection software, for example, leverages fault-detection algorithms and preset thresholds to more efficiently identify unusual behavior and potentially problematic trends. It might reveal that the machine has a new resonant frequency that indicates a mechanical problem in the making or that a drive is drawing progressively higher current and needs to be checked. Timely access to that type of information can enable quick action to prevent line stoppage.

Fast access to insights

The true value of visualization lies in presenting key performance indicators in a way that enables stakeholders to easily access it in context and take action. Maintenance might need to see faults, error codes and spares inventory on a tablet, for example, whereas a facilities manager may be more interested in viewing energy consumption and throughput on their laptop. Applications built for specific analysis and reporting purposes like quality, energy, and fault management are designed to take very large amounts of data and put them into formats that are easily digestible and actionable. Alternatively, developer tools are designed to simplify and speed the process of building home-grown versions.

Modern graphics packages can be used to develop rich, immersive 3-D renderings. This isn’t just restricted to data plots. These suites can create detailed models of the assets on the factory floor, linked to status information and performance data. Users can scan and zoom to view different equipment, clicking to drill down into quantitative information. More sophisticated versions combine the plant model with satellite mapping data to enable management to monitor widely-separated assets at a glance, pinpointing the location of faults in seconds.

Consider alarm management for a global food and beverage company. Imagine that you could view a world map that marks each facility with a colored dot (green, yellow, red) to show the operating status. When you see a red dot marking the Peoria plant, you click on it to access the 3-D model, which shows that the bottling line is shut down. By zooming in, you can see that one of the doors on the machine is ajar. The software doesn’t just streamline diagnostics, it enables you to see how long the line has been down and how much production has been lost. You can also check the status of other plants to see whether they can make up for the shortfall.

The most effective way to deliver this information is on customized dashboards that present multiple metrics on a single display. When tailored to the job role – machine operator, plant manager, maintenance tech, system integrator – these support rapid decision-making. To take the above example one step further, the fault detection information could appear in just one corner of a web-based visualization environment. The top right corner might display energy consumption, while the bottom left corner could show overall equipment effectiveness (OEE) and the bottom right corner provide access to historical trends for any of a number of key performance indicators. Anytime you want more detail, you can drill down to see quantitative data by enterprise, facility, machine, and even shift or operator.

Data is valuable only to the degree that it can be converted into information. Today’s intelligent factory can generate a frightening amount of data. If not managed properly, it can not only fail to benefit the enterprise, it can cause active harm. Using the latest analysis and visualization techniques, end users and OEMs can conquer the data monster, converting the data stream into insights to improve performance of the organization, top to bottom.
