Supply Chain Disruption
 2010/03/08  Can contingency planning increase flexibility and minimize risk exposure to supply chain disruptions? Obviously yes, but what is it about the contingency planning process that relates to flexibility? That question is asked by Joseph B Skipper and Joe B Hanna in Minimizing supply chain disruption risk through enhanced flexibility. Surprisingly, this article suggests that only very few variables of contingency planning are positively related to flexibility…puzzling, isn’t it?

2010/02/18  One of the regular readers of my blog alerted me to an article in the NY Times titled Slow Trip Across Sea Aids Profit and Environment. As it turns out the Danish shipping giant Maersk has halved its top cruising speed over the last two years, thus cutting fuel costs, cutting emissions and perhaps cutting disruptions costs, too? After all, if you know that your shipment will arrive late, you are perhaps less concerned with not being just in time?

2010/01/11  Still thinking about my recent post on the importance of security of supply, I first added salt and grit to the list of critical supplies for the UK. Now you can throw in gas, too. The BBC reports that National Grid has issued its latest “balancing alert” on gas supplies. These alerts are a signal to the market to increase gas supplies, and encourage electricity providers to use alternative fuels such as coal. It comes as low temperatures in the UK continued to drive demand, and as outages at the Norwegian gas facility Nyhamna continues. And what is my role here?

2010/01/07  Today’s rather cryptic title reflects on the impacts of the current winter weather, and is a fitting follow-up to yesterday’s article on the security of supply. The UK transportation systems seems to be particularly suffering under heavy loads of snow, and now they seem to be running out of salt and grit for their snowed-in roads. No grit means no cleared roads means no one able to get anywhere and a no-show of people everywhere.

2009/12/22  The idea for this post came from a question on Linkedin: Holidays = Holi.delays? One thing is the usual Christmas/New Year slowdown. Add to that Global Warming suddenly giving the Copenhagen Agreement the cold shoulder, almost literally, causing severe weather all over Europe, the UK, and the United States, leaving travellers stranded on the Eurostar trains under the English Channel, prompting a major rethink of Eurostar’s customer service. People were stuck at airports like Frankfurt, Germany or Luton, UK. It’s the same scene everywhere, chaos, chaos and chaos and lots of people desperate to get home for the holidays. But what about their Christmas presents?

2009/12/10 Today is an important day here in Norway. Some Mr. Barack Obama comes for a visit to collect some Nobel Peace Prize, creating all sorts of havoc in the transportation system of our small capital along the way. I have a couple of friends who are flying out from Oslo airport this morning, five minutes before the scheduled arrival of said honored guest. I bet they and many other travellers will expect some heavy delays this morning.

2009/11/17  How could I have missed this paper? I was preparing my 2009-lecture on supply chain risk for tomorrow and while looking for some YouTube videos on supply chain risk to spice up my 3-hour presentation, I came across a short snippet featuring Christopher Tang from UCLA, who was talking about three strategies for building a robust supply chain, related to (1) supply, (2) product, and (3) demand. The video does not refer to it, but fascinated as I was, I did some more digging and came up with his 2006 paper Robust strategies for mitigating supply chain disruptions, which list not three, but nine strategies.

2009/11/16 I’ve said so before, sometimes new articles are found in new and unlikely places. The other day I was proofreading the paper of a colleague and something caught my attention in her reference list. A brand new article, just out: Managing disruptions in supply chains: A case study of a retail supply chain by Adegoke Oke and Mohan Gopalakrishnan. Now, here was a chance to learn something new…so I thought, and so I did. However, I’m not sure I follow the authors in their risk categorization: supply, demand and “miscellanous” risk? What is this “miscellanous” risk?

2009/09/21  How are companies located in sparse transport networks affected by supply chain disruptions? This article develops a new framework for the categorization of supply chains, and introduces the notion of the constrained supply chain. Within the constrained supply chain framework, a company can address its locational disadvantage by either redesigning the supply chain towards a better structure, in order to gain better location, or by redesigning the supply chain towards a better organization, in order to gain better preparedness.

2009/09/14 It is unfortunate that many companies still leave risk management and business continuity to security professionals, business continuity planners or insurance professionals. So say Yossi Sheffi and James B Rice in their 2005 article A Supply Chain View of the Resilient Enterprise. It is unfortunate that it is this way, because building a resilient enterprise is an enterprise-wide undertaking that is about so much more than simply preparing a company for disruptions.

2009/08/31 Apparently there must be something really special about Paul Kleindorfer. Otherwise there would be no reason for Morris A Cohen and Howard Kunreuther to write their tribute to him in their 2007 article Operations Risk Management: Overview of Paul Kleindorfer’s Contributions. But what is it that makes Paul Kleindorfer so interesting that it compelled these two authors to write a whole article about him?

2009/08/24 After studying supply chain risk research for some time I have begun to realize that much of the supply chain risk literature lacks direction and that each researcher or strand of researchers have their own presuppositions as to what supply chain risk is and how it should be addressed. In Knemeyer, A. M., Zinn, W. & Eroglu, C. (2009) Proactive planning for catastrophic events in supply chains, fortunately, there is a clear direction for further research and practical application as to how companies can evaluate and plan for catastrophic risk in supply chains.
