- A number of trends like globalisation, outsourcing, single sourcing, and leanness have together created a more vulnerable supply chain. This increased vulnerability has made supply chain risk issues a hot topic in academia as well as in industry. There has, however, been a lack of suitable models. The objective of this paper is to develop one such model – a conceptual model with the help of which risks, seen from the perspective of a single focal company in the chain, related to disturbances and interruptions in the physical flow in the supply chain, could be structured and described on a general level. Only economic risks are considered. The paper is based on a literature review and some case studies. The literature review was focused on articles and reports/books on supply chain risk management and related areas. There are one main case study (Beta) and two smaller ones (Alfa and Gamma). The author has spent five weeks on the floor in two of the factories of Beta. One basic assumption in the model is that the supply chain can be divided into three "parts" named: Demand side, Production and Supply side. Another assumption is that there exists a need to analyse the supply chain flow-related risks both from the perspective of the single company in the chain and from the perspective of the supply chain of which it is a part. Three existing cases illustrate the use of the model. Finally, weaknesses of the model are discussed and some possible directions for further elaboration are presented.

Valuation of Supply Chain Flow Risks by Indexing
- 2005

Ingår i: Papers from the 17th NOFOMA conference held in Copenhagen, Denmark, 2005.

Konferensbidrag (refereegranskat)abstract
- The paper is based on a general conceptual supply chain flow risk model developed in an earlier paper, a literature review and case studies. The paper has the title "Developing a supply chain risk model" and is reported as a final paper at the NOFOMA 2005 conference. The literature review has been focusing articles and reports/books on supply chain management. Some of its findings have earlier been reported in a book chapter in Brindley (2004). There is one main case-study, presented here as case Beta and two minor cases (Alfa and Gamma). The author spent five weeks during the autumn of 2004 on the floor in two of the factories of Beta. That resulted in three internal reports to Beta and a lot of experience and ideas about supply chain flow related risks including the valuation of risks through indexing. Earlier drafts of this paper have on some occasions been tested on risk managers of Beta and developed further based on their feedback. The three cases illustrate the use of the valuation model. Finally is concluded that using indexes can be a way of quickly and with limited resources getting a broad grip of the total risks in the supply chain – not least in new risk situations. The alternative is often not to have any figure at all for the supply chain risks. But we have to be careful because indexes create a new risk – the risk that we believe too much in them.
