The model by Amtzen et al. (1995) also addresses
many international issues. However, it is a completely
deterministic model, and the inclusion of two
different kinds of performance measures in the objective
function is not clear. One of the most comprehensive
models is the model developed by Cole
(1995), but it does not include international features
and ignores BOM constraints.
The above considerations allow us to claim that
there exist many research opportunities for develoing more comprehensive global supply chain models
that include BOM constraints, more stochastic factors,
and qualitative aspects that are very important
within a global environment. Specific opportunities
for research are the following:
explicit inclusion of more stochastic features in
modeling international supply chains;
consideration of vendor and transportation channel
reliability in the selection of vendors and
transportation channels;
