What is enterprise PLM? The answer is today’s Teamcenter.
By Margaret Furleigh – As Teamcenter has evolved as the world’s most widely used enterprise PLM software, the challenge has been to explain in simple terms the enormity and complexity of what Teamcenter can do to transform businesses … and help companies become more agile and adapt to disruptions, whether caused by changing technology, regulations, markets or competition.

If you’re a PLM user, where are you in your PLM journey? Are you primarily focused on product data management (PDM), controlling your designs, documents, BOMs and processes … or have you grown from PDM to reach more people, beyond functional boundaries, or outside your company to suppliers, partners or customers? Maybe you’ve extended from product development to manufacturing and service, or brought in requirements and program management. Are you using PLM to transform the way your business manages product costs, quality, safety, reliability, or sustainabilty? more>

BOM Management: An introduction
By Susan Zimmerlee – What exactly is BOM Management?  Is that the same as BOM Configuration Management?  Or product variability management? Or Master Data Management?  Or a PLM BOM???

The answer seems to be that it depends on who you ask!

BOM management is a tough topic because those words mean something different to each company that I work with.  Even within a single company, you could ask different departments and get different answers.

Which bill of materials management or BOM management solution is best for you? I’ve sat on both the selling and buying end of this discussion, and there is no single answer for everybody. It’s like asking – which vehicle is best?

The answer depends on if you’re hauling heavy loads or trying to get someplace really fast. The BOM management discussion needs to be similar – what is it that you need your BOM management system to do for you? Whether you make paper towels or space ships, at a basic level, BOM management is a critical element that takes you from an idea to a delivered product. To have more detailed discussions about BOM management, we need to establish a baseline of some of the key elements involved:

  • Part: Managing a part bill of materials, also known as the physical product definition or product master, is commonly the main topic of Master Data Management (MDM) discussions.
  • Design: In a design BOM (often called the virtual product definition), mechanical designers and engineering are usually focused on generating the 3D components that make up the product.
  • DMU: Digital mock up (or DMU) refers to the ability to virtually view and interrogate your configured BOM throughout its lifecycle.
  • BOM Configuration Management: BOM configuration management is the discipline of managing the content of the product definition throughout its lifecycle.
  • Variability: Product variability is part of BOM configuration management.
  • Architecture: To better manage configuration and product variability, product architectures help to organize similar content across several products.
  • Coordinated Change: Coordinating product change across various product representations is an issue that is gaining more and more visibility as products grow more and more complex.

Declarative Configuration when Change is Constant
By Dave McLeish – Change is a double-edged sword. To set the scene let’s first focus on recent change for the good as relates to our own domain of product lifecycle management (PLM). In the past few years, increased mobility with smart phones and tablets has provided new opportunities for mobile access to PLM. Adoption of familiar user interface (UI) patterns from everyday life (shopping cart, smart search) and enhanced possibilities for user experience through touch and virtual assistants have enabled more of the “extended enterprise” to embrace PLM. From the shop floor where there’s touch screen access to work instructions to executives empowered to simply search, sign off and interact with dashboards on their device of choice, increasingly the whole enterprise can contribute to and view the digital thread from product development to delivery.

At the heart of this change for the good is the rich web-based access to PLM that has been made possible by html5. Rich capabilities that have meant we can begin to reimagine how we collaborate and deliver products from inception, through realization and utilization. Zero-install rich, browser-based solutions remove the need for desktop install and reduce the IT deployment overhead through firewall friendly standard https requirements.

But developing in the browser has its challenges when targeting rich capabilities over high latency WAN and with limited memory resources. Arguably the greatest challenge is managing change. Whilst the emergence of HTML5 and CSS3 among other standards have provided a reliable basis for developing web solutions, the same cannot be said for much of the web development space. more> https://goo.gl/NjgcsC

PLM and Digitalization Will Redefine Engineering and Manufacturing

By Pat Toensmeier – “We are in a digital industrial revolution,” affirmed Thomas Maurer, senior director of strategy for PLM software at Siemens.

“We see great disruption in manufacturing — size alone is no longer a sustainable advantage [for companies],” said Scott Reese, vice president of cloud platforms at Autodesk. “Three people with funding can disrupt an industry.”

Autodesk and Siemens cited the following as the game-changers:

  • Analysis of Big Data from smart applications like interconnected machines and systems as well as watches and smartphones
  • The cloud, which allows real-time access to projects worldwide and increases the ability of users to work with designs, production processes, and other aspects of manufacturing

Modeling the truck as a whole: Scania uses LMS Imagine.Lab Amesim for testing approach
SIEMENS – Just how do you design a truck?

And especially a truck that needs to haul loads of timber out of snowy Scandinavian forests or coal out of dusty, unpredictable Indonesian mines?

Or, simply be able to run dependably 24 hours a day, seven days a week on the highway?

Precision is the answer for Scania. Obtaining this precision equals the right type of design early in the process. This is just one of the reasons why this global truck manufacturer uses LMS Imagine.Lab™ software. The engineering team counts on this tool to simulate the entire vehicle dynamics, including the hydraulics and the driveline, and to couple various systems such as electronics to create a “virtual” truck.

A leader in the truck and bus market, the Swedish multinational was founded in 1891. Since then, the company has produced and delivered more than 1,400,000 trucks and buses for heavy transportation. You can imagine that a lot has changed since Gustaf Eriksson designed a usable petrol engine in 1902, the year the company manufactured its first truck. more> http://tinyurl.com/l3er3qc

Siemens – LMS controls engineering is an engineering discipline that deals with designing and implementing control systems to achieve a desired overall system behavior. It is the backbone of “smart” products. In its basic form, a control system lets you measure a performance factor in the product using sensors. Based on this measurement data, you can adjust the behavior of product to regulate the performance factor towards a desired objective.

The first step is to understand the requirements. You can design a control system that can meet multiple objectives, but it is important to understand the different objectives and the interactions. How fast should a product react to change in the system? What about a change in external conditions?

You need to get a big picture view. Some of the requirements could set performance goals, which have to be optimized, while others serve as constraints to be satisfied. Some of these requirements can be competing against each other and the design should carefully trade off between competing requirements.

Then we draw out a boundary diagram of the system architecture. What are the components of the system that can be measured by sensors, and which system properties can be changed by actuation to satisfy the requirements? At this point, we do a requirement feasibility analysis to see if the existing sensors and actuators can actually meet the system objectives. Such analysis is mostly done today using system simulation with computer models. Examining the analysis results, we can see if the conceptual system architecture is really possible. If yes, we start a detailed design.

We start by dividing the controller into units according to the required functions. When designing an engine control system, for example, we have to make sure that we are delivering the required torque. To do this, you design a torque management function that “measures” the torque demand through the driver accelerator pedal input. Then this is translated into appropriate airflow and spark-timing actuations to deliver the demanded torque at the engine crank shaft.

In parallel, you look at the fuel management function that seeks to minimize fuel consumption while delivering the required fuel to generate torque. The emission control and thermal management functions also impose constraints on how the airflow, spark timing and fuel system are actuated to ensure that exhaust emissions are minimized and the engine operates in an efficient temperature range. It is a bit like completing a 10,000 piece jigsaw puzzle.

To realize the control system within the overall architecture, we start to define the interfaces and populate the various system functions to fulfill requirements. Today, computer models of the controller units are built to virtualize the functions. The units and their interfaces are rendered graphically to assist the engineers in rapidly evolving design processes. In parallel, we design and implement test cases to make sure that the control system works and meets requirements. more> http://tinyurl.com/nme6utm

Shipbuilding industry at a crossroads

Siemens – On February 20, 2014, the Global Shipbuilding Executive Summit (GSES) members, which included more than 80 executives from government and industry from both the USA and Europe, focused on four areas:

  1. Pre-contract award process
  2. Design and engineering processes
  3. Shipyard productivity improvements
  4. Shipbuilding process improvements.

There were two groups of 10 members each that focused on developing a specific set of steps to improve each of the four focus areas over the next 15-18 months, including setting a set of goals for the next GSES in February 2015 and selecting an executive mentor to help guide each team. At the conclusion to the summit, the members voted on the top recommendations to pursue over the next 12 months. There were eight of them.

The top three recommendations were:

  1. Collaboratively develop requirements that are aligned with and consistent with budgets;
  2. Reduce uniqueness in future ship classes, i.e., common systems; and
  3. Optimize the material flow through shipyards.

The other five of the eight recommendations will be considered in the next phase of this long-term program between government and industry to improve shipbuilding productivity and lower the overall total ownership cost of future ship classes and fleets. Now, cross-functional teams are being formed to pursue each of the top three recommendations. They will meet monthly and have quarterly reviews with the mentors and a final progress report to GSES VI in February 2015.

The top priority for each recommendation is for the results of team research to have significant and measureable impact on the cost of future ship classes and to share these recommendations with shipbuilders around the world to improve shipbuilding productivity via technical papers, presentations and briefings. more> http://tinyurl.com/nmvn3ee
