Supply System Structure, Management and Performance : A Conceptual Model

This paper contributes to the debate within the supply chain management field on the structure, operational management and performance measurement of supply systems. It draws on influential work from these fields in order to support the presentation of a conceptual model. This represents a synthesis of the ideas and concepts discussed, and acts as a focus for subsequent discussion. After presentation and explanation of the model, the structure of supply systems is considered. The relationships are explored between this and both the type of product that is exchanged and the nature of the demand profile. Conclusions are drawn that suggest that the architecture of the supply network should be determined once those factors are clarified and understood in the context of specific supply situations. The role of intermediary organizations within supply systems is discussed. It is then argued that a number of key variables influence the success of the management of the supply system and of its performance. Issues relating to these variable classes are discussed. Conclusions are drawn that highlight directions for further research
