A virtual supply chain model for qos assessment

Abstract

A hybrid virtual supply chain model for the assessment of Quality of Service (QoS) in supply chains is being presented. Due to the large complexity of the problem domain a combined-analytical and simulation-model has been recognised as the best solution for QoS evaluation within a supply chain. The main problem of building such a model is the level of detail, which on one hand is limited by the transparency of business processes of contributing partners and on the other by the desired relevancy of the gathered results. Our model builds on data that are usually made public or are at least subject to contract terms among partners in a supply chain and provide a "good-enough" foundation for QoS evaluation.
