In 1993, National Car Rental faced liquidation. General Motors Corporation (National's parent) took a $744 million charge against earnings related to its ownership of National Car Rental Systems. National faced liquidation, with the loss of 7,500 jobs, unless it could show a profit in the short term. National initiated a comprehensive revenue management program whose core is a suite of analytic...

We want to reveal the usefulness of mobile robots by showing concrete applications in human daily life through this study. In this paper, our trials to realize several specific tasks are shown.

And finally, a network-based stationeries rental servic...

Property asset management is keenly influenced by the market rental price for the services and asset quality. Renovation is conceived as a form of redevelopment that returns the property back to its pristine state after experiencing quality deterioration. We formulate a two-factor renovation model under rental price and quality uncertainty and a fixed investment cost. The renovation policy is d...

We define and solve a simple extension of the ski-rental problem [4]. In the classical version, the algorithm needs to decide when to switch from renting to buying. In our version, no pure buy option is available: even after switching to the buy option, the algorithm needs to pay some reduced rent. We present an online algorithm for this problem with a matching lower bound.

This paper proposes a generalized on-line risk-reward model, by introducing the notion of the probabilistic forecast. Using this model, we investigate the on-line rental problem. We design the risk rental algorithms under the basic probability forecast and the geometric distribution probability forecast, respectively. In contrast to the existing competitive analyses of the on-line rental proble...
