In the following sections, we give a brief
definition of the value chain system and then
describe the development of the SD–DES simulation
models of it. We then describe the outsourcing
situation and the use of the hybrid model in
evaluating the alternatives. Then we describe how
the modified AHP analysis is used to make the final
decisions and discuss the advantages of the use of
this modified AHP over making the decisions based
on simulation results only.
