Remarks on the remaining service time upon reaching a target level in the M/G/1 queue
In this note we establish connections between new and previous results on the remaining service time upon reaching a target level in the M/G/1 queue.

Duality in option pricing based on prices of other derivatives
We clarify a financial meaning of duality in the semi-infinite programming problem which emerges in the context of determining a derivative price range based only on the no-arbi...

Stationary remaining service time conditional on queue length
In Mandelbaum and Yechiali (1979) a simple formula is derived for the expected stationary remaining service time in a FIFO M/G/1 queue, conditional on the number of customers

A note on scenario reduction for two-stage stochastic programs
We extend earlier work on scenario reduction by relying directly on Fortet–Mourier metrics instead of using upper bounds given in terms of mass transportation problems. The impo...

Robust portfolio selection with uncertain exit time using worst-case VaR strategy
In this paper we consider the robust portfolio selection problem involving two types of uncertainties; the uncertainty in the distribution of exit time and the uncertainty in the ...
