A model is developed to identify the optimal capital expansion decisions for producers of

s consumable products. The model features an optional selection of corporate level in a product

tree hierarchy and a choice of several optimizing objective functions.

The model assumes that intermediate product demand is directly dependent on demand

for consumable products. Intermediate product demands are derived from demand for

consumable products using a product tree similar to a bill of materials. Restrictions exist on

the productive capacity of all products in the product tree, and interdependences exist between

producers of the various products. Likewise, the availability of labor limits production

capacities for all products in the product tree. The capital available for the capacity

expansions can either be capital equity or corporate debt.

The model identities the expansion strategy which optimizes the chosen economic

objective function. A case study is analyzed with linear programming software to determine

the optimal expansion strategy for a tire manufacturer given a hypothetical market demand for
