摘要：Motivated 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 costs of manufacturing the single-function and multifunction products. Third, we examine the ...

摘要：This paper considers a supply chain setting where several capacitated suppliers compete for orders from a single retailer in a multiperiod environment. At each period, the retailer places orders to the suppliers in response to the prices they announce. Each supplier has a fixed capacity. We consider a make-to-stock setting where the retailer can carry inventory. The retailer faces exogenous, price-dependent demand. We study the problem using ideas from fluid models. In particular, we (i) analy...

摘要：Vendor managed inventory systems are becoming increasingly popular. An important issue in implementing a vendor managed inventory scheme is the contracting terms that dictate the ownership of the inventory and the responsibility of inventory replenishment decisions. Thus the performance of a vendor managed system crucially depends on these terms and on how inventory-related costs are shared in a supply chain. We consider a system where a manufacturer supplies a single product to a retailer who...

摘要：Buyers often find that obtaining complete information about suppliers is costly. In such scenarios, there is a trade-off between the costs of obtaining information and the benefits that accrue to the owners of such information. There are also various ways in which the missing information can be obtained or inferred. In this paper, we compare the efficiency of obtaining information via the classical mechanism design approach, which relies on the information available before the contracts are de...

摘要：e use a real-options approach to analyze investments in process improvement. We develop a simple, stochastic model of a firm making investment decisions in process improvement. Our analysis offers several interesting insights into investments in process improvement. First, early investment in process improvement results in valuable knowledge, which helps increase the value of the option to invest in process improvement in future periods. This may motivate a firm to invest in process improvemen...

摘要：W e consider the problem of scheduling operations in bufferless robotic cells that produce identical parts using either single-gripper or dual-gripper robots. The objective is to find a cyclic sequence of robot moves that minimizes the long-run average time to produce a part or, equivalently, maximizes the throughput. Obtaining an efficient algorithm for an optimum k-unit cyclic solution (k >= 1) has been a longstanding open problem. For both single-gripper and dual-gripper cells, the approxim...

摘要：Technologies 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 retailer facing a stochastic lead time for order fulfillment. We characterize a replenishment po...

摘要：AIthough extensive academic research has examined the dynamics of interpersonal interactions between service providers and customers, much less research has investigated customer service encounters through technological interfaces such as the Web in electronic commerce transactions. Corporate websites have become an important point of contact with customers for many companies. Service has been described as one of the most important attributes for online business to influence traffic and sales....

摘要：Greater interdependence among workers and activities not only increases the need for internal communication, but it also imposes complications and barriers to effective information exchange. Intraorganizational communication capabilities of certain information systems can help overcome these barriers. However, the extent to which certain systems are promoted as communication tools depends largely on management's interpretation of their usefulness, which in turn may be largely dependent on oper...

摘要：We identify and analyze a scenario where a firm first opens up what we call a detached market, by offering a new product that meets a customer need that is very different from (i.e., detached from) the need met by the old established product. Our analysis builds on the previous studies that describe alternate ways in which a new product might open a new market and ultimately encroach on an existing market. Consider the example of cell phones: They opened up a new detached market by meeting the...
