✦ Synopsis

We consider the problem of running a one-unit failure system such that the probability that the system is operating over an entire prespecified time interval (or at least at some time instant during the interval) is maximized. A fixed number of unused units having identically distributed random operating times are at the controller's disposal. Simple assumptions are made on the stochastic failure mechanism. In particular, the time required to activate a unit for the system is supposed to be constant. Analyzing the associated dynamic programming equations yields closed-form solutions.

## Abstract This paper describes a model and a decision support tool for the regulation of a lake–river system using both goal sets and goal points for the water level over the year. The inflow forecast is updated periodically, which results in a series of dynamic rolling horizon goal programming p

## Abstract Two simple formulae involving only one variable are presented for the simple and rapid estimation of the mean lifetime (τ) of exchange in uncoupled, paripartite AB systems. These formulae are shown to provide τ values comparable to those obtained from total line‐shape analysis.
