We consider the problem of a firm (“the buyer”) that must acquire a fixed number (L) of items. The buyer can acquire these items either at a fixed buy-it-now price in the open market or by participating in a sequence of NL auctions. The objective of the buyer is to minimize his expected...

In many industries, customers are offered free shipping whenever an order placed exceeds a minimum quantity specified by suppliers. This allows the suppliers to achieve economies of scale in terms of production and distribution by encouraging customers to place large orders. In this paper, we...

We consider the dynamic repair allocation problem for a general multi-component system that is maintained by a limited number of repairmen. Component functioning and repair times are exponentially distributed random variables with known parameters. At most one repairman may be assigned to a...

This paper studies adaptive estimation of nonlinear regression models with i.i.d. error terms . Previously in the literature, the adaptive maximum likelihood (AMLE) has been proposed only when the densities of the error terms are assumed to be symmetric.

Raised floor systems (RFS) were initially developed for computer room applications. As an alternative for general office space fitout, they have not been widely accepted, particularly in Australia. Despite the potential exhibited, such as improved ventilation and air quality when used with...
