In this article, we use closed-form solutions to solve Wee and Yu (1997) deteriorating inventory model with a temporary price discount and Martin's (1994) EOQ model with a temporary sale price. In Wee and Yu (1997) and Martin's (1994), the benefits during the temporary price discount purchase...

In this article, we generalize Lev and Weiss's (1990) finite horizon economic order quantity (EOQ) model with cost change to the inventory system with deterioration. Supplier announces some or all of cost parameters may change after a decided time. Depending on whether the inventory is depleted...

A quadratic programming model is developed for predicting the credit card holders' behaviors. This quadratic program is solved by a new algorithm. This algorithm optimizes the objective function along certain directions in the null space of the constraint equations. In this work, the results...

In this paper, an alternative randomized response procedure is given that allows us to estimate the population proportion in addition to the probability of providing a truthful answer. It overcomes a difficulty associated with traditional randomized response techniques. Properties of the...
