In most deterministic manufacturing decision models, demand is either known or induced by pricing decisions in the period that the demand is experienced. However, in more realistic market scenarios consumers make purchase decisions with respect to price, not only in the current period, but also in past and future periods. We model a joint(More)
The risk of supply disruption increases as firms seek to procure from cheaper, but unproven, suppliers. We model a supply chain consisting of a single buyer and two suppliers, both of whom compete for the buyer's order and face risk of supply disruption. One supplier is comparatively more reliable but also more expensive, while the other unreliable one is(More)
A significant and growing volume of global trade travels on container ships, and each year larger ships are introduced. For this reason, the Container Stowage Problem, a fundamental problem in marine cargo transportation involving the optimal assignment of shipping containers of various types to specific storage locations in container ship at each port in(More)
W e introduce and analyze a model that explicitly considers the timing effect of intertemporal pricing— the concept, found in practice, that demand during a sale is increasing in the time since the last sale. We present structural results that characterize the interaction between the decision to hold a sale and the inventory-ordering decision. We show that(More)
In this paper, we investigate the boundedness character, the periodic character and the global behavior of positive solutions of the difference equation x n+1 = A n + x p n−k x p n , n = 0, 1, · · · , where k ∈ N and {A n } is a two periodic sequence of nonnegative real numbers and the initial conditions x −k , · · · , x 0 are arbitrary positive real(More)
