This work aims to generalize and formalize the problem of macro task alloca
tion to aggregated production resources in the virtual enterprise context.
Firstly, the product/process constraints are identified without any conside
ration of the resources. Then, the current availability of the aggregated r
esources within the virtual enterprise is taken into account. This paper do
es not address the allocation problem as such but provides a generic formal
ization of the feasibility domain as a support for human decision-makers in
a dynamic production network.
