In this paper we generalize the newsboy model to optimize the scheduli
ng of purchasing orders for large projects. The timely completion of a
typical project hinges upon receiving all the purchased components by
the time they are scheduled to be used. We show how to minimize the t
otal expected cost of the project, including lateness penalty cost and
holding costs. The main contribution of the paper is in solving the p
roblem for more than one component while considering the interdependen
cies that exist among them. We outline an analytic solution and presen
t fast heuristics.
