On the basis of purchasing literature a study has been made of the goods and services to which e-contacts are relevant. When differentiating between the various types of goods, differentiation is also made between the various kinds of suppliers' relations as well. Subsequently, the relations sensitive to the influence of e-contacts are examined on the basis of the degree of routine of the relevant activities and the related contacts. New possibilities for actors become crystallised in new roles and this leads to hypotheses on the demands made of the various actors, notably where logistic flows and "optimal establishment locations" are concerned. On that basis a dynamic location model can then be put forward for logistic activities so that within a perpetual reorientation process new locations become popular only to, in time, become unpopular because of the occurrence of congestion.
