Rolls-Royce and Altair Collaboration Leverages AI<\/a><\/p>\n

\n

Altair and Rolls-Royce Germany recently announced a strategic collaboration to address a wide variety of use cases including applying data science to the vast amounts of engineering testing data, which can lead to a significantly reduced number of sensors needed. <\/p>\n

\u201cWe share a common vision on the convergence of AI and engineering to drive significant positive business outcomes. Altair has unique domain expertise and best-in-class, low-code data analytics technology. This collaboration will enable us to bridge the gap between engineering and data science, and empower our engineers to truly be engineers, focused on extracting the benefits of machine learning (ML) and artificial intelligence (AI) from our data,\u201d said Dr. Peter Wehle, head of innovation and R&T, Rolls-Royce Deutschland. \u201cUltimately this collaboration will help to democratize our data analytics, enabling our engineers to make better daily data-driven decisions, and transform our business and products.\u201d<\/p>\n

Like many large manufacturers, Rolls-Royce works with large amounts of expensive data, and the use of AI and advanced data analytics have been at the heart of its business for more than 20 years. As part of its IntelligentEngine vision, this collaboration aims to connect AI and engineering even closer to derive business value.<\/p>\n

While Altair already provides Rolls-Royce with numerous standard engineering tools including Hyperworks (FEA Pre\/Post) and Optistruct (topology optimization), it came up with a disruptive meshless structural analysis tool (Simsolid) and added a range of data analytics tools to its portfolio.  The next step shall be to connect those tools to unlock the full potential for extremely fast and deep insights into the structural system behavior. \"PeterDr. Peter Wehle, head of innovation and R&T, Rolls-Royce Deutschland<\/span><\/span><\/p>\n

Connecting structural engineering and data analytics will help to transform the development process, explains Wehle. \u201cTechnically, our long-term vision is to build a system level design recommender system. Practically we would like to give the non-data scientist engineers access to data science methods within a software environment they can work in and that can be maintained,\u201d says Wehle. \u201cUltimately this collaboration will help to democratize our data analytics, enabling our engineers to make better daily data-driven decisions, and transform our business and products.\u201d<\/span><\/p>\n

Specifically, the collaboration sets the stage for Rolls Royce to embedding data science or artificial intelligence into the engine design process itself. Initially, Rolls-Royce Germany will leverage Altair’s Knowledge Works to enable engineers to apply machine learning (ML) methods utilizing simulation data, test data, manufacturing data, and operational data. Knowledge Works is designed so users can easily and efficiently access disparate data sources and formats in a low code\/no code environment, transform the data, use it to build ML models, and share knowledge discovery across the business.<\/p>\n

The collaboration is also about allowing engineers to be engineers \u2013 creating a low code environment where engineers can effectively leverage data to realize meaningful insights without a deep data science background. \u201cWith this convergence of simulation and AI, we are actually providing these tools in a single pane of glass allowing engineers to drag and drop tools in order to further use models for the predictions and the validations of their design,\u201d Altair CTO Sam Mahalingam tells IndustryWeek.<\/p>\n

Empowering the design process<\/b><\/p>\n

Successfully navigating the design process is a crucial when bringing any new product to market. Unfortunately, a lot of important information is not available during the design concept phase. \u201cAs a result, decisions are based on the rules that have been defined as well as years of expertise,\u201d says Mahalingam. \u201cThe lack of information during the concept design phase means a lot of iteration needs to take place, as a product enters into the detail design phase. This process leads to prolonged engine design lifecycle, often taking 10 years.\u201d<\/p>\n

Rules and lessons learned over decades have traditional guided the decision-making process at this stage, adds Wehle. \u201cTools like risk reviews or failure mode analyses with experienced engineers play an essential role. Extensive simulation and test campaigns produce vast amounts of very detailed and complex data. Particularly during these phases, the engineering work reaches a peak resource consumption,\u201d says Wehle. \u201cAs this information becomes available late in the process, much of this valuable data cannot be used for design improvements directly. Equally, highly valuable production and in-service data that characterize the real product behavior become available once the product is in regular service.\u201d<\/p>\n

Often, there is a general conflict where valuable data is both complex and late. \u201cIdeally, we would like to have it much earlier and as simple information. Having more of that information available early in the process should enable us to run less and more effective testing and analysis,\u201d says Wehle. \u201cThe growing demand for innovative solutions in short time scales also drives the need for a cultural change in the way engineering works.\u201d<\/p>\n

\"SamAltair CTO Sam Mahalingam<\/span><\/span>Rolls Royce is helping make that cultural shift by using its data innovation catalyst, R2<\/sup> Data Labs, to support each of the business units to unlock the value in data own. This includes its Digital Academy, which trains people across the business in digital skills, such as having an agile mindset, which can adapt and pivot to downstream challenges during a project. \u201cFrom an artificial intelligence ethics and trustworthiness perspective, we also use our breakthrough Aletheia Framework toolkit, which scrutinizes the application of an AI to ensure it is ethical, and also controls bias by a five-step checking process on the decision made by an AI,\u201d says Wehle. \u201cThis allows us to trust its activities and demonstrate they are ethical and is something we have published for free for anyone to use in any AI context.\u201d<\/p>\n

A significant goal is to bring the three different types of disparate data available to the design engineer, explains Mahalingam. \u201cThis includes historical data of all of the physics-based simulations from past designs, physical lab test feedback and real time operating data captured while an engine is in service,\u201d he says. \u201cThe challenge is determining how to bring all of this disparate information together, so the initial design concept does not require so many iterations. This is where building a data-driven machine learning model can yield predictions to influence and validate the design at the concept phase itself.\u201d<\/p>\n

It is equally important to be able to create machine learning models that will work for a varying types of an engineering domains. \u201cThe structural use cases are different from the computational fluid dynamics use cases, and the same machine learning model will not work for all the different domains,\u201d says Mahalingam. \u201cThis is where Altair and Rolls Royce are really working together to make this happen.\u201d<\/p>\n

Selecting use cases<\/b><\/p>\n

Data science techniques like classification, regression, clustering association rule discovery or anomaly detection in general are powerful tools for discovering knowledge from large datasets. The starting point of any Knowledge Discovery in Data (KDD) process is a situation where there is rich data (tremendous amounts of data stored in information repositories) and poor information (high level summaries important for decision makings are hidden in the large amount of data).<\/p>\n

\"AA heavily instrument engine is being prepared for a Fan Blade Off test.<\/span>Rolls-Royce Germany<\/span><\/span>\u201cThe exploration and analysis of large quantities of data in order to discover meaningful patterns and rules is closing the gap between data and information. The goal of applying this approach to the engineering development process shall be to make as much useful information available as early as possible. Along with that complex data shall be turned into simple and useful information that is available when needed,\u201d says Wehle. \u201cA combination of simple \u2018Wise Rules\u2019 and super-fast simulation techniques might allow for early identification of aspects relevant for the design. Those shall combine knowledge from various disciplines. Only that in depth understanding can lead to true robust designs as well as cost effective and fast development campaigns \u2013 actually this means doing the right things.\u201d<\/p>\n

\u201cThe use cases that we are going to work with Rolls-Royce on are truly going to benefit us in terms of making sure that we pick the right data science, algorithm or use cases as we evolve to provide AI based models,\u201d says Mahalingam. \u201cIt also involves that whole knowledge we will automatically be providing so design engineers don’t have to get out of that single pane of glass kind of an experience to augment machine learning into the validation phase.\u201d<\/p>\n

Adds Wehle, \u201cConsequent use of data using data science techniques therefore will actually be the enabler for better products in shorter time scales. In many cases asking the right questions is helping to see how data analytics can help with simplifying the engineering process.\u201d<\/p>\n

<\/div>\n

The right questions<\/b><\/p>\n

Can my product operate in a different mission?<\/b> \u2013 \u201cOften existing or similar products shall be operated in environments they were not originally developed for,\u201d says Wehle. \u201cChaotic combinations of artificial mission assumptions can be turned into generic rules. Those again can be used to understand if a product is good to go or what needs to change. Complexity reduction using models with many input parameters can give a precise understanding of driving factors and limits.\u201d<\/p>\n

What causes the highest stresses?<\/b> \u2013 \u201cTypically, high effort is needed to calculate vast amounts of load combinations to find the sizing stress condition,\u201d says Wehle. \u201cWhat if we could know upfront which of those combinations are relevant. Decision tree classifiers are particularly powerful as they are intuitively understandable. In fact, they can be used in a technical discussion with pen and paper. Simple rules that can help to see the wood through the trees.\u201d<\/p>\n

Could each part know how strong it is?<\/b> \u2013 \u201cWhy not? Smart Engine Components can learn quite a bit about their component performance, reserve factors or material usage,\u201d says Wehle. \u201cThey can give immediate answers or recommendations on what needs to change in their design or the environment. Data analysis techniques in combination with classical engineering tools are a powerful combination to focus on the right questions at the right point in time.\u201d<\/p>\n<\/div>\n

Over the past few years, there\u2019s been a distinct tendency to associate smart manufacturing with mega-enterprises in sectors such as automotive, aerospace, and the process industry. In fact, the roots of this radical, data-driven approach lie firmly in the German Mittelstand <\/i>of family-owned, industrial small and medium-sized enterprises (SMEs). <\/p>\n

Back in 2011, the German government\u2019s ambitious Industry 4.0 initiative encouraged many such companies to start gathering and analyzing the information generated by their plant and equipment. More recently, it\u2019s true that much of the momentum behind smart manufacturing has been provided by larger organizations. However, those pioneering German SMEs still tell an important story. There are compelling reasons why, when carefully planned and implemented, smart manufacturing is every bit as valuable for smaller businesses. In some cases, the benefits of deployment may be even more accessible, and the returns realized faster.<\/p>\n

The data is out there<\/b><\/p>\n

Making the argument in favor of smart manufacturing for SMEs typically involves a fair amount of myth-busting. To start with, deployment of smart manufacturing systems is rarely likely to demand high levels of capital investment or major implementation of new infrastructure. Most modern plants will already be generating the data around which new solutions can be built. Even if that\u2019s not the case, it is generally a straightforward task to retrofit sensors to legacy equipment. In other words, the data is already out there. The real challenges lie in collating and preparing information from disparate sources, then transforming it into actionable insight.<\/p>\n

Accessible to all <\/b><\/p>\n

Another common misconception is that smart manufacturing will inevitably require significant in-house IT and\/or data science expertise. Again, that\u2019s often not the case. Smart manufacturing solutions are now being built around principles of democratization and accessibility. Low- or no-code technology is the way forward here. In fact, too much involvement from IT specialists may be more hindrance than help. That\u2019s because, regardless of the size of the enterprise involved, effective smart manufacturing systems are almost invariably shaped by those directly responsible for production. <\/p>\n

For an SME, an ideal approach might be a machine-learning solution that can be used intuitively by its own operations team. The multivariate time series data that is generated on the shopfloor can then be fed into the system and, based on the predictive insights and alerts it provides, will enable frontline staff to determine the corrective action required. <\/p>\n

Crucially, such an approach recognizes that the operations team is best-placed to reach the right decisions. What\u2019s more, it provides them with all the control and visibility needed to do so. And because the entire process, from identifying the use case to verifying the results, resides with the operations team, much shorter time-to-value is delivered.   <\/p>\n

Where is the return?<\/b><\/p>\n

A third potential pitfall lies in a simple failure to identify, in advance, the anticipated ROI for a smart manufacturing initiative. This is reflected in a number of cases where businesses have set out to reap data, and only then tried to determine where and when the payback will materialize. <\/p>\n

In many respects, smaller organizations are less likely to fall into this trap. By their very nature, they tend to be focused and agile, and adopt a more cautious approach to investment. In addition, smaller organizations often opt to introduce smart manufacturing in specific areas rather than throughout the entire production process or as part of a broader digital transformation strategy. This makes it easier to monitor the results. As experience grows and lessons are learned, smart manufacturing systems can then be extended. Deployment therefore becomes an organic process, driven by and from the shopfloor. <\/p>\n

Getting more from less<\/b><\/p>\n

Fortunately, problems with smart manufacturing deployment are the exception rather than the rule. Enterprises across numerous industries are now achieving positive, quantifiable results. Potential benefits encompass reduced plant downtime, elimination of bottlenecks, and improvements in product quality that in turn realize significant warranty cost savings. For smaller enterprises, the most worthwhile returns will often be found in enhancements to productivity and efficiency. That\u2019s not just because these businesses tend to work on very tight margins. With fewer resources in terms of both plant and manpower, it is even more important that they are consistently doing the right things, at the right times, and in the right places. For example, in one SME use case we\u2019re familiar with, data analytics is pivotal to ensure that production lines are continuously balanced to optimize inventory utilization. <\/p>\n

Delivering for SMEs<\/b><\/p>\n

Another compelling smart manufacturing application in the SME sector involves the monitoring of process data to help build in quality, rather than effectively add it at the end of the production line. For example, one SME is using smart manufacturing to visualize and monitor in real time the quality of assembly processes such as torque audits. Any deviations and trends are flagged as soon as they become an issue. The aim is zero defects and a completely transparent manufacturing process; expensive rework at the end-of-line testing stage is significantly reduced. <\/p>\n

SMEs are also highly active in the fast-growing market for smart products. Here, understanding rapidly changing customer requirements and innovating accordingly are key to remaining competitive. Typically, artificial intelligence (AI), ML, and the Internet of Things are regarded as the enabling components. However, when it comes to creating products that can become smarter and more agile, smart manufacturing\u2019s ability to integrate these elements with the design and simulation processes can help enterprises innovate and change product direction more quickly. <\/p>\n

Levelling the playing field<\/b><\/p>\n

Data is now recognized as a critical commercial resource. On the face of it, mega-enterprises might appear to be at an advantage, simply on the basis that they have more to work with. However, by taking advantage of characteristics such as flatter structures, proximity to the production process, and an ability to focus on more modest and better-defined applications, SMEs can make smart manufacturing work just as hard.<\/p>\n

Far from being the preserve of larger enterprises, smart manufacturing is a thoroughly democratic asset that can and should be considered by businesses of any size. Not merely to level the playing field, but to tilt it in favor of manufacturers that are simply better at exploiting the rich insight buried within their production data. <\/p>\n

Ericsson, Telia, and Sahlgrenska University Hospital use AI to help improve COVID-19 planning<\/a><\/p>\n

\n

With hospital and healthcare resources stretched to the limit, planning has become more important, and more difficult than under normal circumstances. While the pandemic shown that the needs of hospitals can be hard to predict, it has also highlighted how resilient networks and mobile data can help cope with these challenges.<\/p>\n

\n
\n

Ericsson, Telia, and Sahlgrenska University Hospital (SU) are now collaborating together to create and refine insight models for planning and predicting healthcare resources and demands.<\/p>\n

The research innovation project, started in September 2020, combines advanced analysis and AI models, along with healthcare information, to more effectively plan healthcare resources. The project uses data supplied by Telia Crowd Insights, which is irreversibly anonymized and aggregated from Telia\u2019s Swedish mobile network.<\/p>\n<\/p><\/div>\n

Ericsson has extensive knowledge of AI and telecom networks and by combining this competence with Telia\u2019s Crowd Insights data and SU\u2019s healthcare expertise and real-time experience with COVID-19 it is possible to more effectively plan and predicting healthcare resources.<\/p>\n

For example, by using this data, it becomes possible to improve estimations of how many COVID-19 patients will be admitted to a hospital. As part of this project, SU is also collaborating with Chalmers University of Technology in Sweden to help improve COVID-19 planning.  <\/p>\n

Peter Laurin, Head of Managed Services, Ericsson, says \u201cEricsson has a long-standing commitment to Technology for Good. We are now extending this to using our AI tools and expertise to help relieve the unprecedented challenges presented by Covid-19. Our collaboration with Telia and Sahlgrenska University Hospital proves the value that data together with technologies like Artificial Intelligence and Machine Learning can bring to healthcare and society\u201d.<\/p>\n
