Tools of the Manufacturing Trade, Part VI
In my last article, I posed the question, “Suppose you want to take some action – either at the design end or the manufacturing end. What tools can you rely on after you’ve done the background work and now want to move on to execution?”
The simple answer I gave was, “This is where software tools come in.”
I then proceeded to go into details about some interesting software tools that aid the designer, or manufacturer, in decision making about green and sustainable actions to take.
Shortly after that posting, I was invited to participate in a live (and simultaneously web-broadcast) Sustainability Summit at Autodesk in San Francisco.
Not surprisingly, the event was well organized and attended by an interesting mix of media, industry and students (including a sizable audience “attending” via a YouTube live link). It was interesting to hear a large corporation with a number of software tools for designers and engineers in this field, like the Autodesk® Inventor® 3D CAD software, discuss where they think the market is going and what software tools will have to allow the designer, and manufacturer, to do.
The program was comprised of a series of discussions and panel discussion starting with company CEO Carl Bass in conversation with Marc Gunther, a Fortune and GreenBiz contributor, discussing the importance of sustainability in the future of design. Although this conversation was design centric, it had a lot of leads into green and sustainable manufacturing.
Other participants included Clean Tech Partner Burt Hamner of Hydrovolts; myself representing our lab at UC Berkeley on green manufacturing; Daniel Talancon and Vince Romanin, UC Berkeley graduate students on their Eco-Fridge design using Inventor; and Ken Sanders of Gensler on their Shanghai Tower design and other sustainable building projects.
Rather than rattling on about the meeting here, I’ve decided to take the easy way out and post links to the recorded YouTube presentations and discussions. That is more effective and, to me, better to hear the participants speaking about their views in their own words.
As a set up to the recording of my comments as part of the panel discussion lead by Autodesk’s Sarah Krasley, I was asked to describe our “spatial vs temporal” matrix of manufacturing activities. This was first presented in the January 21, 2010 posting as part of a low hanging fruit series.
As a quick refresher, the matrix is designed to illustrate different levels of control and flexibility in manufacturing from a temporal view (ie what comes first, second, third, and so on) and spatial view (where in the enterprise – broadly viewed – can actions be taken). I had detailed the temporal configuration as including four levels, from product design at level 1 through process design and planning (manufacturing plan) to parameter selection and process optimization to post manufacturing operations (finishing, etc.) at level 4. It was noted that the flexibility to make decisions decreases as we move away from design towards manufacturing.
This makes sense. On the factory floor we are no longer able to change the product or component design, material or other features. We may not, at level 3, be able to do much about the suite of machines we intend to use to produce the part. We most likely can adjust some of the operating parameters or, at level 4, do some finishing or alteration to overcome a problem.
The spatial domains are defined along the same lines except they will move outward from production specifics in the plant to facility design, enterprise design, logistics (or inter-enterprise) and supply chain and distribution.
The figure below was included as a graphical representation of the matrix and is worth repeating here.
The temporal axis is horizontal and the spatial axis is vertical. As one moves up and to the right in the figure one can suffer a loss of decision making capability as all earlier decisions in the product design cycle, or lower in the supply chain, effect the ability to make decisions at higher levels. How you affect what is happening at any location within this matrix depends on what information you have about the process or system represented there, what your understanding is of what this information says about what’s going on, what ability you have respond to this understanding, if needed (or leave it alone if it is performing correctly), what “levers and buttons” you have at your disposal to make a response and, finally, what means you have to determine if your response had any impact and, if so, how much.
That is, with respect to our tools discussion here, how well the software you are using to integrate across these different levels includes all the critical information, reasoning, behavioral models, visualization, etc. to support your work and decisionmaking.
So, with that set up on the summit in general and the background on my particular contribution, the links to the different presentations are listed below. They are only 3-5 minutes in length so are easily digestible (with the exception of the interview with the CEO – which is much longer.)
Warning – this was a a commercial event so it is, not surprisingly, very professionally done and has a commercial message. But, the contributors are genuine in their enthusiasm and their messages are on target and worth listening to.
The links are:
– Overview of the program and Sara Krasley interviewing the panel
– UC Berkeley students on their Eco-fridge design
– Ken Sanders of Gensler speaking about green building design
– Dave Dornfeld speaking about the temporal – spatial matrix discussed above
– Carl Bass, Autodesk CEO, being interviewed (this is a long one at 34 minutes)
Or you can see the complete “playlist” on line.
For sure, there is other software on the market that addresses many of these same issues. You should check that out on your own.
Finally, next time we’ll revisit the leveraging discussion.
David Dornfeld is the Will C. Hall Family Chair in Engineering in Mechanical Engineering at University of California Berkeley. He leads the Laboratory for Manufacturing and Sustainability (LMAS), and he writes the Green Manufacturing blog.
