摘要：How should a firm with limited capacity introduce a new product? Should it introduce the product as soon as possible or delay introduction to build up inventory? How do the product and market characteristics affect the firm's decisions? To answer such questions, we analyze new product introductions under capacity restrictions using a two-period model with diffusion-type demand. Combining marketing and operations management decisions in a stylized model, we optimize the production and sales pla...

摘要：Firms often cite cost savings as a reason why they charge separately for add-ons. Firms also often face situations where consumers' price sensitivity is correlated with their valuation of add-ons. While cost savings may directly translate into profit gains in some scenarios, this study examines the strategic implications of add-on pricing and is the first to suggest that cost savings from add-on pricing may in fact result in profit loss for firms when consumers are heterogeneous in price sensi...

摘要：We consider a stochastically failing component that will be needed at a random future time when an emergency occurs. If the component is not operational at that time, the system incurs a large penalty, which we want to avoid through inspections and replacements. We propose a model and solution algorithm for finding an inspection policy that minimizes the infinite horizon discounted expected penalty, replacement, and inspection costs. We also discuss structural properties of the solution, as we...

摘要：This note complements the study of Burke, Carillo, and Vakharia ( hereafter BCV) which analyzes a class of single-product multisourcing problems under stochastic demand and random yields. The purpose is twofold. First, we prove that the objective function used by these authors is only a lower bound for the expected profit for which we provide the correct expression. Second, we show on some of the numerical instances provided in BCV's study that the structure and the performance of the BCV orde...

摘要：This study examines a deterministic material requirements planning (MRP) problem where lead times at subsequent ordering moments differ. Adequate replenishment methods that can cope with lead time differences are lacking because of the order crossover phenomenon, that is, replenishment orders are not received in the sequence they are ordered. This study specifies how to handle order crossovers and recalculate planned order releases after an update of gross requirements. The optimal (s, S) poli...

摘要：This study develops an approximate optimal control problem to produce time-dependent bid prices for the airline network revenue management problem. The main contributions of our study are the analysis of time-dependent bid prices in continuous time and the use of splines to modify the problem into an approximate second-order cone program (ASOCP). The spline representation of bid prices permits the number of variables to depend solely on the number of resources and not on the size of the bookin...

摘要：Formal contracts represent an important governance instrument with which firms exercise control of and compensate partners in R&D projects. The specific type of contract used, however, can vary significantly across projects. In some, firms' govern partnering relationships through fixed-price contracts, whereas in others, firms' use more flexible time and materials or performance-based contracts. How do these choices affect the costs and benefits that arise from greater levels of partner integr...

摘要：Dispensing of mass prophylaxis can be critical to public health during emergency situations and involves complex decisions that must be made in a short period of time. This study presents a model and solution approach for optimizing point-of-dispensing (POD) location and capacity decisions. This approach is part of a decision support system designed to help officials prepare for and respond to public health emergencies. The model selects PODs from a candidate set and suggests how to staff each...

摘要：We consider a setting in which a manufacturer sequentially sources two components and uses reverse auction to select a supplier with the lowest bidding price for each component. The manufacturer chooses a quantity to order from each supplier and a price for selling the final product. We show that the interplay between the direct competition faced by suppliers in providing their respective components and the sequence whereby the manufacturer sources components influence system performance in a ...
