Cold storage devices such as tape and optical discs are a good solution for reducing the total cost of ownership for storing data. However, there is a drawback in that media and drives are separated, and placing media into drives when accessing data needs a few minutes of time. Though placing correlated data together in the same medium reduces media exchange, multidimensional searches disrupt i...

Critics of current tying doctrine argue that metering ties can increase consumer welfare and total welfare without increasing output and that they generally increase both welfare measures. Contrary to those claims, we prove that metering ties always lower both consumer welfare and total welfare unless they increase capital good output. We further show that under market conditions we argue are r...

All resources need to be managed to realize opportunities. Isolating the benefits of Information Technology and relating them to the associated costs has proved elusive and threatened emerging opportunities. A change of approach has been advocated to overcome these problems which focuses on the Total Cost of Ownership. Over the past several years, the Total Cost of Ownership has been both haile...

What effect does firm structure have on the product service quality on offer? We answer this question by empirically assessing the impacts of complete vertical separation, such as ownership unbundling, on the quality of service delivered by a liberalized network industry. Electricity distribution utilities in New Zealand are considered for this purpose. The results show robust evidence that own...

In this paper, we consider fuzzy inventory with backorder. First, we fuzzify the storing cost a, backorder cost b, cost of placing an order c, total demand r, order quantity q, and shortage quantity s as the triangular fuzzy numbers in the total cost. From these, we can obtain the fuzzy total cost. Using the signed distance method to defuzzify, we get the estimate of the total cost in the fuzzy...

Examining two different changes in retail format, we show that consumers alter their purchase behavior when the retail context changes. In both settings, the change in purchasing behavior is consistent with the effect being driven by an interpersonal interaction between the consumer and the retail clerk. We therefore model the change in format as a “social friction” in which consumers may not p...

Die benutzerzentrierte Qualitätssicherung, die mit dem weit verbreiteten TCO-Zertifikat zu einem de facto Standard für die Qualitätssicherung von Büroprodukten führte, wird in Schweden seit 1998 unter dem Namen „UsersAward“ auch für Software-Produkte angewendet. „UsersAward“ verfolgt dabei einen ganzheitlichen Prozessansatz, bei dem die Nutzerzufriedenheit mit Software in den sechs Bereichen Ge...

Loan fraud is a critical factor in the insolvency of financial institutions, so companies make an effort to reduce the loss from fraud by building a model for proactive fraud prediction. However, there are still two critical problems to be resolved for the fraud detection: (1) the lack of cost sensitivity between type I error and type II error in most prediction models, and (2) highly skewed di...

The retail industry is being revolutionized by the movement in consumer perception of shopping exemplified by “Shopping is Theater”. Increasingly, consumers are expecting shopping to be a highly interactive and rewarding experience. This has been driving the need for reduced time to market of newer retailing ideas, and the use of advances in hardware and software technologies to create a richer...
