The bankruptcy prediction problem can be considered an ordinal classification problem. The classical theory of Rough Sets describesobjects by discrete attributes, and does not take into account the order-ing of the attributes values. This paper proposes a modification of theRough Set approach...

While the net present value (NPV) approach is widely accepted as the right framework for studying production and inventory control systems, average cost (AC) models are more widely used. For the well known EOQ model it can be veri_ed that (under certain conditions) the AC approach gives near...

The Port of Rotterdam is a key container transshipment hub for Europe. Inland container shipping is important to connect the hinterland (40% market share). Barges visit several terminals per round-trip through the Port, thus requiring a proper planning support - to avoid planning problems such...

Ride-share systems, which aim to bring together travelers with similar itineraries and time schedules, may provide significant societal and environmental benefits by reducing the number of cars used for personal travel and improving the utilization of available seat capacity. Effective and...

We address the value of RFID technology enabled information to manage perishables in the context of a supplier that sells a random lifetime product subject to stochastic demand and lost sales. The product's lifetime is largely determined by the time and temperature history in the supply chain....

In this article we focus on product return handling and warehousingissues. In some businesses return rates can be well over 20% andreturns can be especially costly when not handled properly. In spiteof this, many managers have handled returns extemporarily. The factthat quantitative methods...

We introduce two new measures of the performance of a scientist. One measure, referred to as the halpha;-index, generalizes the well-known h-index or Hirsch index. The other measure, referred to as the galpha;-index, generalizes the closely related g-index. We analyze theoretically the...

In this paper we derive the worst-case ratio of an online algorithm for the Traveling Salesman Problem (TSP) with two disclosure dates. This problem, a variant of the online TSP with release dates, is characterized by the disclosure of a job's location at one point in time followed by the...

Electronic auctions have rapidly increased in popularity, but the consequences of switching to an electronic auction are unclear. In part this is because multiple changes occur at the same time so one can only observe the combined effect of these changes and not the effect of each separate...
