1- The conventional product-mix decision model is based on the assumption that there
are only two resources, direct labor and material, that may have limited capacities in a
system. In other words, the conventional approach ignores the fact that overhead
activities performed in a company may also have limited capacities and, therefore,
may become bottlenecks just as direct resources. The model developed in this thesis
brings a solution to this problem by including capacity-related constraints for indirect
resources as well as direct resources in the product-mix problem.
