Given increased global competition and consumers’ increasing price sensitivity, apparel retailers such as J. C. Penney have begun to focus on quick response and cycle time reduction as part of their overall business strategy. Extensive use of interorganizational linkages with major suppliers has become a key component in designing more effective, responsive strategies to meet changing corporate...

Energy-efficiency is becoming increasingly important for storage systems to reduce the total cost of ownership (TCO). In this paper, we propose an energy saving policy named eRAID for conventional disk based RAID-1 systems using redundancy. In particular, we develop a dynamic performance control scheme with the help of a performance predictor based on queueing network theory. Moreover, we discu...

BACKGROUND The International Maternal, Pediatric, and Adolescent Clinical Trials P1060 trial demonstrated superior outcomes for HIV-infected children less than 3 years old initiating antiretroviral therapy (ART) with lopinavir/ritonavir compared to nevirapine, but lopinavir/ritonavir is four-fold costlier. DESIGN/METHODS We used the Cost-Effectiveness of Preventing AIDS Complications (CEPAC)-...

The population health effect and cost-effectiveness of implementing intensive blood pressure goals in high-cardiovascular disease (CVD) risk adults have not been described. Using the CVD Policy Model, CVD events, treatment costs, quality-adjusted life years, and drug and monitoring costs were simulated over 2016 to 2026 for hypertensive patients aged 35 to 74 years. We projected the effectivene...

OBJECTIVE The purpose of this research was to assess the local cost savings resulting from community water fluoridation, given current exposure levels to other fluoride sources. METHODS Adopting a societal perspective and using a discount rate of 4 percent, we compared the annual per person cost of fluoridation with the cost of averted disease and productivity losses. The latter was the produ...

We subject claims about the benefits of activity-based costing systems to the scrutiny of analytical models incorporating rational behavior by users of product costing systems. We find that a monopolist Is almost always strictly better off using multiple cost drivers as in an activity-based costing (ABC) system even when the system makes measurement errors in assigning overhead costs to activit...

This paper studies the following online replacement problem. There is a real function f(t), called the ow rate, deened over a nite time horizon 0; T]. It is known that m f(t) M for some reals 0 m < M. At time 0 an online player starts to pay money at the rate f(0). At each time 0 < t T the player may changeover and continue paying money at the rate f(t). The complication is that each such chang...

Handling freight in a crossdocking terminal is labor-intensive, and therefore costly, because workers must unload, sort, and transfer a wide variety of freight from incoming to outgoing trailers. The eÆciency of workers depends, in large part, on how trailers are assigned to doors around the dock; that is, on its layout. A good layout reduces travel distances without creating congestion, but, u...

Fashion, and especially apparel, is the fastest-growing category in online shopping. As consumers requires sensory experience especially for apparel goods for which their appearance matters most, images play a key role not only in conveying crucial information that is hard to express in text, but also in affecting consumer’s attitude and emotion towards the product. However, research related to...
