摘要:Ranking and selection procedures are standard methods for selecting the best of a. finite number of simulated design alternatives based on a desired level of statistical evidence for correct selection. But the link between statistical significance and. financial significance is indirect, and there has been little or no research into it. This paper presents a new approach to the simulation selection problem, one that maximizes the expected net present value of decisions made when using stochast...

摘要:We study a single-product single-location inventory system under periodic review, where excess demand is lost and the replenishment lead time is positive. The performance measure of interest is the long-run average holding cost and lost sales penalty cost. For a large class of demand distributions, we show that when the lost sales penalty becomes large compared to the holding cost, the relative difference between the cost of the optimal policy and the best order-up-to policy converges to zero....

摘要:We consider a retailer that sells a product with uncertain demand over a. finite selling season. The retailer sets an initial stocking quantity and, at some predetermined point in the season, optimally marks down remaining inventory. We modify this classic setting by introducing three types of consumers: myopic consumers, who always purchase at the initial full price; bargain-hunting consumers, who purchase only if the discounted price is sufficiently low; and strategic consumers, who strategi...

摘要:Given a discrete maximization problem with a linear objective function where the coefficients are chosen randomly from a distribution, we would like to evaluate the expected optimal value and the marginal distribution of the optimal solution. We call this the persistency problem for a discrete optimization problem under uncertain objective, and the marginal probability mass function of the optimal solution is named the persistence value. In general, this is a difficult problem to solve, even i...

摘要:This paper presents the. first formal examination of role of causal ambiguity as a barrier to imitation. Here, the aspiring imitator faces a knowledge (i.e., capabilities-based) barrier to imitation that is both causal and ambiguous in a precise sense of both words. Imitation conforms to a well-explicated process of learning by observing. I provide a precise distinction between the intrinsic causal ambiguity associated with a particular strategy and the subjective ambiguity perceived by a chal...

摘要:The importance of material. flow management for a profit-maximizing. firm has been well articulated in the supply chain literature. We demonstrate in our analytical model that a. firm must also actively manage information. flows within the supply chain, which translates to controlling what it knows, as well as what its competitors and suppliers know. In our model of horizontal competition between an informed and an uninformed. firm with a common upstream supplier, material and information. flo...

摘要:This paper investigates the impact of e-waste regulation on new product introduction in a stylized model of the electronics industry. Manufacturers choose the development time and expenditure for each new version of a durable product, which together determine its quality. Consumers purchase the new product and dispose of the last-generation product, which becomes e-waste. The price of a new product strictly increases with its quality and consumers' rational expectation about the time until the...
