Systems Engineering Critical to Tackling IoT’s Challenges

MIND-BOGGLING-COMPLEXITYMillions of devices and users. Trillions of lines of computer code. Thousands of manufacturers with different goals and priorities, acting independently, to create a system whose “scale, rate of evolution, and diversity of stakeholders makes it impossible to do any sort of conventional top-down direction or management, yet whose intended use requires high levels of trust, safety, security and quality of service.”

That’s how Hillary Sillitto, an expert on ultra-large-scale systems (ULSS) and a fellow of the International Council on Systems Engineering (INCOSE), describes the largest system ever conceived: the Internet of Things (IoT).

“Current engineering practice is ahead of the science,” Sillitto said. “We are building systems we do not know how to characterize or analyze, and whose behavior we cannot fully predict.”

That reality has the global community of systems engineers – the people whose specialty was designed to identify and manage the trade-offs inherent in building large-scale systems comprising hundreds, even thousands of subsystems – actively searching for answers. Focus areas range from urging organizations to dramatically change the way they design complex systems to overhauling computer-aided design and engineering tools for the special challenges of systems engineering (SE).

 Managing Subsystem Conflicts

“Systems engineering is as much art as it is science,” said Norman R. Augustine, retired chairman and CEO of US-based global security and aerospace corporation Lockheed Martin and a former member of the US President’s Council of Advisors on Science and Technology. “The essence of systems engineering comes down to the fact that most individuals on a complex project know how to make a brick, but for such projects to be successful you need someone who knows how to build a cathedral.”

In Augustine’s analogy, systems engineers are the master architects who ensure that every subsystem in a project supports and enhances every other subsystem to create an optimized whole. In designing an automobile, for example, systems engineers are responsible for identifying the trade-offs between, for example, fast acceleration and fuel efficiency or weight versus safety. Ideally, experts in each engineering discipline then work together to manage the trade-offs, sub-optimizing some systems to ensure the best possible overall performance. But the ideal is far from the reality.

“The world is just not very good at systems engineering,” laments Augustine, who is helping to apply SE to a light-rail project in the suburbs of a major metropolitan region.

Experts like Augustine give the world a failing grade in SE, in part, due to the chasm between what a strong SE orientation can contribute to organizational success and the lack of commitment to SE among corporate and government leaders.

“The gap is huge, and it is very costly,” said Daniel Krob, president of the Center of Excellence on Systems Architecture, Management, Economy and Strategy (CESAMES) in Paris and professor of computer science at the École Polytechnique.

Charles F. Bolden Jr., administrator of the US National Aeronautics and Space Administration (NASA) and a former astronaut, agrees: “Large companies whom we thought had a strong systems engineering approach don’t, or have let it falter, resulting in lost [business] opportunities, lost time and cost and schedule overruns.”

A large part of the problem, these experts agree, is that engineers in different disciplines don’t collaborate – or even communicate – as much as they should, and that corporate leaders don’t force the point or provide the tools to make collaboration easier. “Without systems engineering, the most likely outcome is a number of separately optimized parts that inefficiently perform the task of the whole, or perform it not all,” Augustine said.

The optimal system of systems rarely arises by optimizing each subsystem, NASA Chief Technologist David Miller explained. The interfaces between subsystems, and between systems and the external environment, are where a system of many systems succeeds or fails, he said.

“In our business, when we think about systems of systems,” Miller said, “we need to take into account not just the performance of the space vehicle, but adaptability to a changing environment and the like — something that I like to call architectural resilience, meaning the ability to be insensitive to change.” That ability will also be central to the success of a constantly evolving system such as the IoT.

The Industrial Internet of Things Promises Safety Wins but Security Risks

You know those signs you always see on construction sites, the ones that say “this workplace has gone 100 days without injury?” Those signs are about to get a major overhaul.

The Industrial Internet of Things (IIoT) is coming, hot on the heels of its domestic cousin, and it’s bringing major changes to the workplace. The fourth industrial revolution will forever change the way we work. Not only will network-aware devices allow us to be more productive, they will also usher in a new era of safety and security practices made possible by interconnected devices.

The Rewards

If you’re familiar with wearable technologies like Google Glass, you might have already guessed that IIoT will use similar gadgetry to help supervisors better understand the condition of their workforce. The technology to measure vital signs, like heart rate and skin temperature, already exists. In a network-aware workplace, these data points will be monitored in real time. It’s been speculated that we will even be able to measure human fatigue as soon as 2016.

It won’t just be humans evaluating this data, either. If you’re a field worker performing a survey in scorching heat, for example, your network-aware orange safety vest might be programmed to alert the home office if your temperature exceeds a set threshold. Similarly, equipment on manufacturing lines will be just as informed of safety standards and practices as you are, and might automatically shut off in the event that you fail to follow procedure.

The Risks

Technology is a double-edged sword, though, and each wearable device and network-aware machine that’s added to the workplace represents a possible point of entry for cyber-attacks.

You might think it’s science fiction, but anonymous U.S. government officials have already shared information about weaponized malware called Stuxnet. The computer worm was allegedly used to invoke a series of incidents that destroyed multiple Iranian centrifuges, dealing a crippling blow to the nation’s nuclear program. Such a weapon could wreak havoc if let loose on IIoT devices, and it’s entirely possible the casualties could be human this time.

In 2015, half of all small businesses were the target of a cyberattack, and it seems that a different major corporation – Target, LinkedIn, Sony etc. – announces a data breach nearly every day now. Personal data is highly valuable on the dark web, which means IIoT devices will almost certainly be the target of cyberattacks. A robust network security solution will be critical for businesses that rely on large numbers of IIoT devices.

The Reality

Although the situation seems dire, there is hope that the war on cybercrime is reaching a turning point. In the past, victims were relegated to playing a defensive role, the best outcome you could hope for was to escape an attack unscathed. Now, however, the FBI and other international agencies are honing their skills and holding attackers accountable more frequently.

Much like the first three industrial revolutions, we won’t fully comprehend what the fourth means until it’s already upon us. You can bet that once new technologies arrive and are exploited, the pace of development will only increase. In the same way that conventional wars have inspired some of the world’s most profound advances in medicine, the war for the web is sure to deliver advances we can’t yet comprehend.

So remember, before you lace up your network-aware steel toes and head to work, make sure you’ve updated them to the latest firmware version. You don’t want to be responsible for setting the sign back to “0 days.”

From Atoms to Airplanes

From Atoms to AirplanesImagine the year is 2045 and you are about to board an airliner for a scheduled nonstop flight from New York City to Paris. The aircraft looks the same as commercial airplanes did in 2015, but advanced technology – from the airplane’s systems to the materials from which it is made – will make this flight different from any that humans experience today.

For starters, the airplane is powered by electricity instead of jet fuel, and its structure doubles as a giant battery that collects and stores solar energy. As a result, the aircraft emits no greenhouse gases. En route to their destination, window-seat passengers may notice that the wings – made from lightweight composite materials – will automatically change shape according to flight conditions. Meanwhile, on the ground, a digital “twin” of the aircraft is helping to predict how it will age throughout its 15- to 20-year service life, enabling technicians to identify and fix emerging maintenance issues as they develop and reduce and eliminate delayed or canceled flights due to mechanical problems.

Futuristic? Absolutely. Fantasy? Think again.

These and other advanced concepts are being explored at the US National Aeronautics and Space Administration’s (NASA) Convergent Aeronautics Solutions program to help make possible new capabilities in commercial aviation. Like the NASA program, aerospace companies around the world are working in collaboration with their governments to develop and perfect advanced technologies, tools and processes to meet aviation’s most pressing challenges: faster new aircraft that can be developed more quickly and that are environmentally sustainable, more affordable, and more efficient to operate and maintain.

Civil Aviation Booming

Aviation accounts for only 2% of global carbon dioxide emissions, according to the International Air Transport Association (IATA), which represents 83% of total airline traffic. As automobiles, trucks and trains reduce their greenhouse gas footprints, however, aviation’s footprint is increasing due to a global increase in air travel. The IATA projects that air travel will grow at a rate of 3.9% annually for the next 20 years. To meet this demand, Europe’s Airbus, as well as Boeing in the US, will produce nearly 1,900 airliners in 2018, up from about 1,400 in 2015 and more than double the number of aircraft the “Big Two” delivered in 2008. Add Canada’s Bombardier and Brazil’s Embraer into the mix, and more than 2,100 commercial aircraft could be delivered in 2018 – a historically high production rate.

In the case of business aviation, engineers are developing technology in anticipation of at least one globe-shrinking jet airplane capable of flying between continents at significantly more than Mach 1 before 2025; the actual speed will depend on the final design, but could be as much as 1,800 kilometers (1,118 miles) per hour at the high altitudes anticipated for the airplane.

Revolutionary Technology

But innovations won’t be limited to airframes, engines and subsystems. The high-performance composites and ultra-high-temperature materials used to build future generations of aircraft and engines also will take dramatic leaps, starting at the molecular level. Boeing and Airbus already have achieved major weight reductions and associated fuel savings by making greater use of composite materials in their 787 and A350 models, respectively, than any of the companies’ previous commercial airplanes. Meanwhile, private and government research facilities all over the world are modeling new types of alloys and various fibers with enhanced structural properties that will make them stronger and lighter, cheaper to produce and able to perform better under extreme operating conditions.

No less effort is being put into advanced production processes. One such process is additive manufacturing (AM), or 3D printing, the process of producing complex parts by melting and building up layer upon layer of material; it’s the reverse of conventional machining, which carves parts from solid blocks of material. GE Aviation in Evendale, Ohio, for example, is using AM to make fuel nozzles of certain jet engines, and Pratt & Whitney (P&W) of East Hartford, Connecticut, is using AM to make advanced turbine components for some jet engines.

Still, the technology is in a very early stage of development, according to materials and manufacturing engineers. “This is a revolutionary technology,” said Lynn Gambill, chief engineer, Manufacturing and Global Services for Pratt & Whitney. “AM lends itself to rapid, energy-efficient manufacturing of products that can be produced no other way and with greatly reduced waste of material.”

While there’s no question aviation will evolve dramatically in coming decades, the speed at which this evolution will occur is less predictable. Bringing new technology to market will require substantial investment and a willingness to accept some level of business risk, two variables that rarely move in lock step in the aerospace industry, said Aaron Hollander, president, chairman and CEO of First Aviation Services in Westport, Connecticut, an engineering-focused, component-maintenance and repair company. “At the same time,” he said, “the aerospace industry has a proud heritage of pushing boundaries and advancing the state of the art, and I’m confident this tradition will continue.”

How Green Technology Is Transforming Traditional Manufacturing Methods

30700767_sManufacturing, along with other industrial processes, is one of the primary industry sectors being targeted for green technology use. Traditional manufacturing methods are transforming into lean, green conserving machines that benefit the planet and the bottom line.

More than that, companies need to communicate how they are dealing positively with climate change to customers who increasingly demand environmentally responsible practices. The consumer class has expanded to the point where upward price pressures are being placed on resources, including construction and industrial materials, energy, and water. The costs of conservation and green technology are more easily justified in this financial climate.

Globally, government-led incentives are being developed for businesses willing to adopt emerging green technologies (EGTs).

What Exactly Is Green Technology?

Plunkett Research defines green technology as the “application of advanced systems and services to wide variety of industry sectors to improve sustainability and efficiency.”

EGTs commonly show improvements in:

  • Energy efficiency and conservation
  • Water conservation and quality
  • Reduction of waste, carbon emissions, and emissions of toxic gasses

In addition, these technologies create systems that promote reuse and recycling of all types of materials.

EGTs can be split into a number of categories including energy; water; environmental, pollution devices and services; and engineering, architecture, and design.

Energy

Renewable and alternative energy production and storage coordinates with energy conservation through the use of green building materials and processes.

Water

Water saving is predominantly performed through conservation and recycling. However, production of potable water is also being promoted through alternate sources such as the desalination of sea water.

Environmental , Pollution Devices and Services

Waste management and disposal have changed over the years to emphasize recycling and reusing what were previously waste materials.

Pollution services include the reduction or elimination of toxic waste and controlling emissions. Services include compliance auditing and inspection as well as engineering, testing, and consulting. Other areas impacted by the green wave are product and systems design and re-engineering to meet new regulations.

Engineering, Architecture, and Design

EGTs are also creating changes within product design and industrial process design, including factory automation, in an effort to drive efficiencies in heating, ventilation, and air conditioning products and building design.

We Must Manage Our Resources

The EPA stated that in 2013 the industrial sector accounted for 21% of all greenhouse gas emissions, right behind electricity production and transportation. The increasing cost of water and energy has caught the attention of manufacturers since 22% of the GDP is produced in water-scarce areas. If things continue at this pace, up to 45% will be produced in these areas by 2050.

When resources are limited, so is growth. This means manufacturers must look for long-term annual savings, not just short term fixes.

Green Technology Can Boost Manufacturing Activity

Somebody has to design and fabricate wind turbine components and solar panels, as well as transport them to where they need to go. Diesel and port fees are rising, discouraging off-shore production and transportation. Green technology could be a boon to U.S. manufacturing.

Green technology will require skills and manufacturing expertise to cost effectively produce components for solar arrays, energy storage, and other technology.

  • The number of parts to build green technology must be reduced
  • Manufacturing of green technology must orient itself to mass production and efficiency
  • EGTs must align themselves to industry standards and capabilities
  • Supply chains for glass, steel, adhesives, and controls must be built

All of these things are needed to reduce the cost to manufacture green technology to the point where it is a (pardon the pun) sustainable business in itself. The demand is there. Green technologies are available and are being integrated into the manufacturing industry every day, making new companies eligible for government contracts and helping them attract and retain customers.

Traditional manufacturing is changing, as it always has, to incorporate new technologies that increase efficiency and decrease cost. It is now integrating green technology because it not only saves money, it saves the Earth. It’s the right thing to do.

Why “Smart” Manufacturing Will Grow in 2016

Why Smart Manufacturing Will Grow in 2016Factories are typically thought of as dark places with people standing on an assembly line working side by side with machines, doing the same thing over and over again. But, that “vision” of the traditional factory has changed thanks largely to the influx of technological advances in how factories operate.

Technology driven factories are cropping up all around the globe in both established and developing countries. Many countries are recognizing the opportunity for change and investing heavily by offering grants and other benefits to help to implement these technology changes.

The EU for example is investing almost 2 Billion Euros into their private/public partnership “Factories of the Future” to encourage manufacturers to take advantage of new technology to improve their factories and to become more efficient, green and profitable. It is not just the EU that is offering a great deal of incentives for manufacturers to switch their operations over to something that looks a little bit like a “great idea”. Even developing countries are offering incentive packages to lure manufacturers to their countries.

Smart manufacturing offers a bevy of benefits and will eventually become the way that every organization creates their products.

The Labor Force

Naysayers like to point out all the workers that will lose their jobs, however, the fact is that these factories actually create indirect jobs. Who really wants to stand in less than ideal conditions all day long at an assembly line anyway?

Luckily one of the reasons that these types of manufacturers are going to be successful is because they will promote job opportunities that will greatly outnumber the jobs currently available with traditional factories.

Studies indicate that the number of indirect jobs that will be needed to support manufacturing in smart factories may actually triple or quadruple in quantity.  Indirect jobs will be a necessity for these types of factories to function.

When computers were first introduced for public/private use, naysayers then said that they would put people out of work and businesses would become completely automated. Similar to that era, the “factory worker” will still be very much part of the process just in a different capacity.

There will always be critics that will predict the worst case scenario, but the reality can be very different then the prediction. Smart factories do not put people out of jobs, it just means that people will have a different role in the process.

Environmental Impact

Smart factories are hailed as the wave of the future now because they can reduce the negative effects that manufacturing has on the environment. Since concern has turned to the environment in the last couple of decades, manufacturers have received the brunt of the criticism for creating an environment that is slowly turning hostile to humanity.

The smart factories utilize reusable packaging options and other methods that greatly reduce the impact on the environment.  Reducing the effects on the environment can include:

  • Reduction in greenhouse gases that have a negative impact on the environment
  • More efficient use of natural resources
  • Improved waste control measures to reduce environmental damage

As more consumers become aware of environmental issues more consumers are demanding change and looking to manufacturers to change how they do business. In response to consumer demand more manufacturers will look to smart factories as a solution.

Industry 4.0

This movement has even generated its own nickname.  The movement to use technology to improve production has adopted the name of Industry 4.0 because it’s the improved way to develop and manufacture all goods.

Since the emergence of Industry 4.0, more and more manufacturers have adopted the practice of utilizing technology that can greatly improve their productivity at a lower cost. Industry 4.0 will change the way manufacturers create goods.  You can expect that 4.0 initiatives will:

  • Look to “closed lifecycle loops” where there is ZERO waste
  • A concerted effort to use only sustainable materials
  • A drastic reduction in overall costs which may be passed on to the end user

Tax Breaks, Government Compliance and Sheer Profits

Smart factories will grow in 2016 because they are simply a more viable option. Governments help manufacturers with their bottom line by offering deep tax breaks. As government regulations become harder and harder to comply with via the use of traditional methods, more and more businesses will opt to choose a method that makes compliance both easier and more cost effective.

This movement is set to really grow by leaps and bounds. As more governments get on board with the idea that it is time for a change and they offer bigger and better tax breaks to entice manufacturers you will see a tremendous change in manufacturing. Manufacturers not only save money thanks to all the incentives but they are able to increase their positive cash flow.

The People Want It

It is not only the government that is making it easy to make the choice to covert. Consumers will be more likely to seek out brands that are using smart factories as their point of origination. It will get to the point in the near future where consumers will avoid products that are crafted in traditional factories.

If you give consumers a choice they will choose the products that are coming from a factory that causes less impact on the environment. But, consumers are thrifty as well – they do not want to pay extra for such products.

Overall

Increased profits, improved reputation, reduced taxes and greater job creation all together sounds an awful lot a recipe for success. The question is not “why” these type of factories will enjoy growth in 2016, but more “how could they not?”

Smart manufacturing has all the components of a successful enterprise. More correctly we should be wondering why there will be any traditional, environmentally offensive factories remaining.

If we have the solution to reduce impact on the environment and create more jobs should we not require that manufacturers take the option?

The growth of these factories will be very difficult to keep up with in 2016 and beyond. They are the solution to so many problems.
