In the wake of catastrophic natural disasters and rising threats of terrorism, the hotel industry has been hit hard by declining revenues and increasing competition. To avoid such a downward spiral, the hotel industry should find remedies to make its operations lean and robust. These remedies...

This paper investigates the rank distribution, cumulative probability, and probability density of price returns for the stocks traded in the KSE and the KOSDAQ market. This research demonstrates that the rank distribution is consistent approximately with the Zipf's law with exponent $\alpha =...

We study the continuous time random walk theory from financial tick data of the yen-dollar exchange rate transacted at the Japanese financial market. The dynamical behavior of returns and volatilities in this case is particularly treated at the long-time limit. We find that the volatility for...

The objective of this research paper is to describe a conceptual framework for evaluating the expected value of supply chain relationships (EVSCR). Various types of supply chain relationships are defined in the literature. Then borrowing basic valuation concepts from finance theory, a supply...

One of the benefits of modular design is ease-of-service. While modular design helps simplify field maintenance, extensive depot maintenance and spare modules are required to support the field maintenance. This study develops a dynamic approach for scheduling preventive maintenance at a depot...
