摘要：We study a firm's optimal strategy to adjust its capacity using demand information. The capacity adjustment is costly and often subject to managerial hurdles, which sometimes make it difficult to adjust capacity multiple times. To clearly analyze the impact of demand learning on the firm's decision, we study two scenarios. In the first scenario, the firm's capacity adjustment cost increases significantly with respect to the number of adjustments because of significant managerial hurdles, and r...

摘要：In this paper we describe the Traveler's Route Choice Problem (TRCP). This is the problem of a traveler in a railway system who plans to take the fastest route to a destination but is faced with a disruption of unknown length on this route. In that case, he can wait until the disruption is over or take a detour route as an alternative. Since the duration of the disruption is not known in advance, he is left with a decision problem under uncertainty. In this paper we model the problem and descr...

摘要：For a polytope P, the Chvatal closure P ' subset of P is obtained by simultaneously strengthening all feasible inequalities cx <= beta (with integral c) to cx <= left perpendicular beta right perpendicular. The number of iterations of this procedure that are needed until the integral hull of P is reached is called the Chvatal rank. If P subset of [0,1](n), then it is known that O(n(2) log n) iterations always suffice and at least (1+1/e - o(1))(n) iterations are sometimes needed, leaving a hug...

摘要：Properties of two large families of scale-free forecast accuracy measures that include popular measures such as mean absolute percentage error, relative error, and squared percentage error, are examined in this paper. We describe the optimal reports when forecasts are evaluated using these measures. We also provide analytic expressions for the optimal Bayes' act associated with these measures under a general power transformation for several well-known probability distributions. We then show th...

摘要：We consider the dynamic casino gambling model initially proposed by Barberis (2012) and study the optimal stopping strategy of a precommitting gambler with cumulative prospect theory (CPT) preferences. We illustrate how the strategies computed in Barberis (2012) [ Barberis N (2012) A model of casino gambling. Management Sci. 58(1): 35-51.] can be strictly improved by reviewing the betting history or by tossing an independent coin, andwe explain that the improvement generated by using randomize...

摘要：The majority of approaches to product line design that have been proposed by marketing scientists assume that the underlying choice model that describes how the customer population will respond to a new product line is known precisely. In reality, however, marketers do not precisely know how the customer population will respond and can only obtain an estimate of the choice model from limited conjoint data. In this paper, we propose a new type of optimization approach for product line design un...

摘要：We develop a framework for determining the optimal resource capacity of each station composing a stochastic network, motivated by applications arising in computer capacity planning and business process management. The problem is mathematically intractable in general and therefore one typically resorts to either simplistic analytical approximations or time-consuming simulation-based optimization methods. Our solution framework includes an iterative methodology that relies only on the capability...

摘要：We explore the procurement of influenza vaccines by a government whose objective is to minimize the expected social costs (including vaccine, vaccine administration, and influenza treatment costs) when a for-profit vaccine supplier has production yield uncertainty, private information about its productivity (adverse selection), and potentially unverifiable production effort (moral hazard). Timeliness is important-costs for both the supplier and the government procurer may increase if part of t...

摘要：We study the mechanism design problem for a seller of an indivisible good in a setting where privately informed buyers can acquire additional information and refine their valuations for the good at a cost. For this setting, we propose optimal (revenue-maximizing) and efficient (welfare-maximizing) mechanisms that induce a right level of investment in information acquisition. We show that because information is costly, in the optimal and even the efficient mechanisms, not all buyers would obtai...

摘要：We propose a novel approach to cross-selling investment products that considers both the customers' and the bank's interests. Our goal is to improve the risk-return profile of the customer's portfolio and the bank's profitability concurrently, essentially creating a win-win situation, while deepening the relationship with an acceptable product. Our cross-selling approach takes the customer's status quo bias into account by starting from the existing customer portfolio, rather than forming an e...
