Multi-stage decision processes are considered, in notation which is an outgrowth of that introduced by Denardo [Denardo, E. 1967. Contraction mappings in the theory underlying dynamic programming. SIAM Rev. 9 165-177.]. Certain Markov decision processes, stochastic games, and risk-sensitive...

Models in which process quality and lot sizing interact have recently been developed. Lot sizes should be reduced to compensate for poor quality if no effective inspection is possible. This note introduces an inspection delay time, measured in units produced after an inspection is made until...

This paper is motivated by the observation that the Japanese have devoted much time and energy to decreasing setup costs in their manufacturing processes and that there has been little in the way of a formal framework available to use to think about such efforts. The object of this paper is to...

We build a discrete time, serially correlated stochastic demand, nonstationary, finite horizon, capacity expansion model that includes (1) economies of scale in capacity costs, (2) positive expansion leadtimes, and (3) a fixed maximum cumulative capacity, called the shell size. When the shell...
