In the standard search problem there is an infinite pool of items whose distribution of values is known. A decision maker draws an item from the pool, observes its value, and decides whether to keep it or to draw another item. He can keep only one item, and he seeks the item with the largest...

We consider a semi-Markov decision process with arbitrary action space; the state space is the nonnegative integers. As in queueing systems, we assume that {0, 1, 2, ..., n + N} is the set of states accessible from state n in one transition, where N is finite and independent of n. The novel feature...

We consider the problem of scheduling the production of a single product at each instant during a time horizon of length T (\leqq \infty ) so as to minimize the average cost per unit time; backlogging of demand and disposal of stock are not allowed. Two types of costs are incurred; the holding cost...

When managing a project with uncertain completion time and unobservable contractor's work rate, self-interest can create conflicts between the project manager and the contractor leading to actions that reduce the profits of both. We first investigate how the concept of supply contract...

type="main" <p>We study the interaction between a group of agents who exert effort to complete a project and a manager who chooses its objectives. The manager has limited commitment power so that she can commit to the objectives only when the project is sufficiently close to completion. We show...</p>
