M by the proliferation of multifunction products, we investigate product portfolio decisions of a single firm by analyzing the impact of three major factors. First, because multifunction products provide complete or partial functionalities of single-function products, we incorporate substitution or cannibalization effects between the potential products. Second, we explicitly model the variable ...

W study the effect of strategic customer behavior on pricing and rationing decisions of a firm selling a single product over two periods. The seller may limit the availability of the product (that is, ration) in the second (clearance) period. Some customers are strategic and respond to the firm’s decisions by timing their purchases. When capacity is nonconstraining and the seller has pricing fl...

T such as radio-frequency identification and global positioning systems can provide improved real-time tracking information for products and replenishment orders along the supply chain. We call this type of visibility order progress information. In this paper, we investigate how order progress information can be used to improve inventory replenishment decisions. To this end, we examine a retail...

The problem of production management can often be cast in the form of a linear program with uncertain parameters and risk constraints. Typically, such problems are treated in the framework of multi-stage Stochastic Programming. Recently, a Robust Counterpart (RC) approach has been proposed, in which the decisions are optimized for the worst realizations of problem parameters. However, an applic...

While several retailers have popularized RFID (RadioFrequency Identification) technology, recent surveys indicate that many firms are still skeptical about it. In addition to variable costs of investment due to RFID tags, firms adopting this technology face significant expenses in upfront fixed costs due to system integration, installation of equipment and so on. Allocation of benefits from thi...
