Although uncertainty is rife in many project management contexts, little is know about adaptively optimizing project schedules. We formulate the problem of adaptively optimizing the expected present value of a project's cash flow, and we show that it is practical to perform the optimization. The...

Many owners of growing privately-held firms make operational and financial decisions in an effort to maximize the expected present value of the proceeds from an Initial Public Offering (IPO). We ask: What is the right time to make an IPO and How should operational and financial decisions be...

Numerically valued reward processes are found in most dynamic programming models. Mitten, however, recently formulated finite horizon sequential decision processes in which a real-valued reward need not be earned at each stage. Instead of the cardinality assumption implicit in past models,...

A supply system's fill rate is the fraction of demand that is met from on-hand inventory. This paper presents formulas for the fill rate of periodic review supply systems that use base-stock-level policies. The first part of the paper contains fill-rate formulas for a single-stage system and...

Simple inequalities are obtained for some operating characteristics of multiserver queueing models. "Loss system" and "delay system" results are presented.
