Abstract. We deal with the problem of making capital investments in ma­
chines for manufacturing a product. Opportunities for investment occur over
time, every such option consists of a capital cost for a new machine and a re­
sulting productivity gain, i.e., a lower production cost for one unit of product.
The goal is that of minimizing the total production and capital costs when
future demand for the product being produced and investment opportunities
are unknown. This can be viewed as a generalization of the ski­rental problem
and related to the mortgage problem [3].
If all possible capital investments obey the rule that lower production costs
require higher capital investments, then we present an algorithm with constant
