Abstract

Every company may be located at the junction of several Supply Chains (SCs) to meet the requirements of many different end customers. To achieve a sustainable competitive advantage over its business rivals, a company needs to continuously improve its relations to its different stakeholders as well as its performance in terms of integrating its decision processes and hence, its communication and information systems. Furthermore, customers’ growing awareness of green and sustainable matters and new national and international regulations force enterprises to rethink their whole system. In this paper we propose a model to quantify the identified potential risks to assist in designing or re-designing a supply chain. So that managers may take adequate decisions to have the continuing ability of satisfying customers’ requirements. A case study, developed at kuehne + nagel Luxembourg is provided.

CONCLUSION

In summary, it can be stated that we developed a tool which enables Kuehne + Nagel to evaluate its customers’ SC’s performance of sustainability, regardless of the domain served by the specific customer. In addition, Kuehne + Nagel can set up a benchmark, by applying this model on its diverse customers. During the development phase of the above explained model, some internal managers suggested introducing the Decision Tree (DT) methodology as a last step of our risk assessment model. Effectively, in a LEAN perspective, the companies’ respective boards of directors want their managers to save time whenever possible. For this reason, they want to get a clear picture of the different risks’ estimated outcomes which is understandable at the first glance and which can support the decision taking process in a more visible way. Though, we consider the DT being ineffective in the logistics environment. The steadily changing state of affairs as well as the immense number of consequences connected to one alteration of the current system would lead to the impossibility of providing the required clear picture and hence to subsequent frustration due to the defeat in evaluating the results’ usability obtained therefrom. However, we agree with [34] explaining that a diagram is usually considered being more comprehensible than a written description of a given problem. For this reason, we suggest our model to be succeeded by the definition of a risk mitigation strategy, whereas the latter should be finalised by a Bow-Tie Model (BTM). In the approach of continuous improvement, this risk assessment needs to be done on a regular basis and the end results need to be analysed, i.e. before the improvement of a SC’s degree of sustainability and hence, before the re-design of the said SC.
